Souza, L.S.; Silva, F.C.A. da

2017-01-01

Industrial Gammagraphy plays an important role in the quality control of various materials and components. It is classified by the International Atomic Energy Agency - IAEA as Category 2, due to its radiation risk caused by the use of high activity radioactive sources. This risk is based on the harmful consequences of human health, described in some accidents in the world, due to failures. In 2012, the 'Brazilian National Workshop on Accident Prevention in Industrial Gammagraphy' was carried out by DIAPI/CNEN, with the objective of disseminating knowledge about radiation accidents. At the time, the IRD/CNEN-RJ carried out a survey with the 75 participants using a form with 22 recommendations to prevent radiological accidents, in order to select the 10 most voted. A statistical study, using the 'Frequency Distribution' method, was performed to define 10 recommendations. The percentage and vote results were obtained by category of the participants and the 10 most important recommendations were defined to prevent radiation accidents. The recommendation that came in first place was 'Always use an individual monitor with alarm during all work'

The Brazilian pharmaceutical industry is heavily dependent on external sources of inputs, capital, and technology. However, the emergence of technological opportunities and the development of biotechnology and the decline of the patent boom and resulting advances by generic drugs have opened windows of opportunities for the local industry. The article examines the Brazilian industry's innovative behavior vis-à-vis these opportunities, showing that although the industry as a whole invests little in innovation, a few large Brazilian companies have expanded their market share and stepped up their investments in research and development, supported by public policies for innovation. Resumo: A indústria farmacêutica brasileira caracteriza-se pela grande dependência de fontes externas de insumos, capital e tecnologia. O surgimento de oportunidades tecnológicas, associadas ao desenvolvimento da biotecnologia e ao fim do boom das patentes com o consequente avanço dos medicamentos genéricos, entretanto, vem abrindo janelas de oportunidades para a indústria local. Este artigo examina o comportamento inovador da indústria brasileira à luz dessas oportunidades, revelando que, embora o conjunto da indústria mantenha baixos níveis de investimentos em inovação, um pequeno grupo de grandes empresas nacionais vem ampliando sua participação no mercado e intensificando seus investimentos em pesquisa e desenvolvimento, apoiados por políticas públicas de inovação.

This paper addresses the effects of the deregulation of the Brazilian air transportation industry in terms of the concentration of the market. We will show some metrics that are commonly used to study the concentration of the industry. This paper uses the Herfindhal- Hirschman Index. This index tends to zero in the competitive scenario, with a large number of small firms, and to one in case of a monopolistic scenario. The paper analyses the dynamics of the concentration of the Brazilian domestic air transportation market, in order to evaluate the effects of deregulation. We conclude that the Brazilian market presents oligopoly characteristics and aspects in its current structure that maintain the market concentrated in spite of the Deregulation measures adopted by the aeronautical authority.

The relationship between policies and the definition of a national program of nuclear energy, is considered. The case under study is the Brazilian one. It is shown that an overall evaluation of market, industry and science and technology is mandatory for the definition of a nuclear energy program, and serious fault and hesitation, leading to contradiction and failure, have their roots in a basic lack of definition in policies. The evolution of the Brazilian Nuclear Energy Program will probably remain at a mediocre level until a definition at the level of policy-making in marketing, industry and science and technology is firmly pursued and maintained.

da Silva Rabêlo, Olivan; de Azevedo Melo, Andrea Sales Soares

2018-03-08

The study analyses the relationships between the main drivers of eco-innovation introduced by innovative industries, focused on cooperation strategy. Eco-innovation is analysed by means of a multidimensional identification strategy, showing the relationships between the independent variables and the variable of interest. The literature discussing environmental innovation is different from the one discussing other types of innovation inasmuch as it seeks to grasp its determinants and to mostly highlight the relevance of environmental regulation. The key feature of this paper is that it ascribes special relevance to cooperation strategy with external partners and to the propensity of innovative industry introducing eco-innovation. A sample of 35,060 Brazilian industries were analysed, between 2003 and 2011, by means of Binomial, Multinomial and Ordinal logistic regressions with microdata collected with the research and innovation department (PINTEC) from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística). The econometric results estimated by the Logit Multinomial method suggest that the cooperation with external partners practiced by innovative industries facilitates the adoption of eco-innovation in dimension 01 with probability of 64.59%, 57.63% in dimension 02 and 81.02% in dimension 03. The data reveal that the higher the degree of eco-innovation complexity, the harder industries seek to obtain cooperation with external partners. When calculating with the Logit Ordinal and Binomial models, cooperation increases the probability that the industry is eco-innovative in 65.09% and 89.34%, respectively. Environmental regulation and innovation in product and information management were also positively correlated as drivers of eco-innovation.

Full Text Available The recent challenges of the Brazilian naval and offshore industry have generated a unique opportunity for studies on technological innovation and economic development. This paper presents the recent developments and future prospects of this industry under the theoretical framework of ‘technological interfaces’. Technological interfaces are defined as the thread of knowledge and technology necessary for establishing a transaction between two or more agents. It is both a theoretical construct and a tool for better understanding industrial coherence and dynamics. The development project of ship and platform construction in Brazil, unveils a potential dynamic similar to large national projects, such as the U.S. space project in the 50s. By establishing scientific parameters of analysis for the study, it is possible to generate a broader diagnosis of the technological interface matrix of the industry, but mainly it is possible to map the framework of operational gaps and the needs for technical-scientific development.

Radiation protection for industrial radiography in the aerospace industry

International Nuclear Information System (INIS)

Morgan, W.E.

1980-01-01

The Boeing Company employs 80 industrial radiographers, operates 90 radiation sources, and takes 10,000 exposures per month. This paper describes the major components of Boeing's radiation protection program: hazard analysis, facilities and equipment design, program administration, and evaluation. In the hazard analysis, each source of radiation is analyzed to determine its hazard and relationship to both man and the environment around it. Once the degree of the hazard is known, facilities and equipment are designed to contain the hazard. This can be anything from a four foot concrete shielded room for an industrial radiographic accelerator, to a piece of rope that isolates an Iridium-192 source during a field radiographic inspection on an aircraft. The administrative functions provide the necessary records, command media, and a radiation source certification program. This certification authorizes the source of radiation to be used under specific conditions agreed upon by both the Radiation Protection Organization and Industrial Radiography Management. The radiation protection program is evaluated through medical exams, personnel monitoring, and area radiation surveys. (H.K.)

The 10 recommendations for prevention of radiation accidents in industrial gamma radiography

International Nuclear Information System (INIS)

Souza, Luana Silva de

2015-01-01

The Industrial Gamma Radiography, as part of Industrial Radiography, stands out as the most widespread and plays an important role in the quality control of different materials and devices. However, IAEA classifies industrial gamma radiography in the Category 2 as very dangerous due to the radiological risk caused by the use of high activity radioactive sources. In March, 2012, a Brazilian Workshop on Prevention of Industrial Gamma Radiography Accident was performed by DIAPI/CNEN with the objective of disseminating knowledge about radiological accidents with radioactive sources in this application. During this Workshop, IRD/CNEN conducted a survey with 75 participants using a form with 22 recommendations to prevent radiological accidents, aiming to select the most voted. This present work aims to perform a detailed statistical study to define the Top 10 Recommendations for industrial gamma radiography operator avoids radiological accidents and to prepare a brochure with these top 10 recommendations to be distributed to all industrial gamma radiography radiation workers. Data analysis was performed using the statistical method 'Frequency Distribution', among the 75 participants categorized as General, RPO, and Other Workers of the area. The results were obtained for each category, accounting for the total of 22 recommendations in its percentage and number of votes, and the top 10 recommendations were defined to prevent radiological accidents. The first place and most important recommendation is 'Always use a personal alarm monitor throughout the work'. One of the conclusions is that the brochure with the Top 10 Recommendations shows to be understandable and useful for dissemination and training of radiation workers to avoid radiological accidents in industrial gamma radiography.

The Brazilian external individual monitoring scenario

International Nuclear Information System (INIS)

Mauricio, Claudia L.P.; Silva, Claudio R. da; Cunha, Paulo G. da

2015-01-01

In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

Industrial applications of radiation technology

In recent years, radiation processing has emerged as an alternative to conventional technologies such as thermal and chemical processing for many industrial applications. The industry is expanding at a fast rate all over the world. The actual industrial benefits on commercial basis, however, depends on the need of the individual society and may vary from country to country. In India, the applications of radiation technology have been found in areas of health care, agriculture, food preservation, industry and environment. Both gamma radiation and electron beam accelerators are being utilized for this purpose. Presently, 6 commercial gamma irradiators housing about 1.5 million curie 60 Co and an annual turnover of over US$ 2 million and 3 commercial electron beam (EB) accelerators with installed capacity of 185 kW are commercially operating in India. The new areas being explored include use of electron beam irradiation for surface treatment, radiation processed membranes for a variety of applications and radiation processing of natural polymers. In the present paper, the current status of this program, especially the recent developments and future direction of radiation processing technology is reviewed. (author)

Technical potential for developing natural gas use in the Brazilian red ceramic industry

International Nuclear Information System (INIS)

Schwob, Marcelo Rousseau Valenca; Henriques, Mauricio Jr.; Szklo, Alexandre

2009-01-01

The red ceramic industry in Brazil, consisting of over 7000 companies, requires large amounts of thermal energy, currently being met mainly by native fuelwood, which causes serious deforestation and soil erosion problems. The use of firewood does not allow achieving good energy performance in industrial ceramic kilns, causing high energy losses, low productivity and low quality products (bricks and roof tiles). Thus, to implement higher added value products, besides mitigate environmental problems caused by deforestation, the use of natural gas by the sector seems to be a promising alternative. Brazil's natural gas market has grown at a fast pace in recent years. Its share in the country's primary energy consumption increased from 3.7% to 9.3% between 1998 and 2007, compared to almost 21% in the world. The development of the Brazilian natural gas industry was grounded on stepping up supplies through integration with Bolivia from where natural gas is imported, together with fiscal incentives for promoting the demand. This paper estimates that the natural gas market that could be developed in the Brazilian red ceramic industry corresponds to less than 5% of the total industrial natural gas consumption, meaning that a major technological transformation of the country's red ceramic industry will not severely affect the natural gas market equilibrium, contributing to reduce the country's high rates of deforestation.

Silva, F.C.A. da; Leocadio, J.C.; Ramalho, A.T.

2008-01-01

An important contribution for Brazilian development, especially for the quality control of products, is the use of radiation sources by conventional industries. There are in Brazil roughly 3,000 radioactive sources spread out among 950 industries. The main industrial practices involved are: industrial radiography, industrial irradiators, industrial accelerators, well logging petroleum and nuclear gauges. More than 1,800 Radiation Protection Officers (RPOs) were qualified to work in these practices. The present work presents a brief description of the safety control over industrial radioactive installations performed by the Brazilian Regulatory Authority, i.e. the National Commission of Nuclear Energy (CNEN). This paper also describes the national system for radiation safety inspections, the regulation infrastructure and the national inventory of industrial installations. The inspections are based on specific indicators, and their periodicity depends on the risk and type of installation. The present work discusses some relevant aspects that must be considered during the inspections, in order to make the inspections more efficient in controlling the sources. One of these aspects regards the evaluation of the storage place for the sources, a very important parameter for preventing future risky situations. (author)

Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). The RBMN Project (Repository for Low and Intermediate-Level Radioactive Wastes) aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (author)

The preparation of enantiomerically pure or enriched substances is of fundamental importance to pharmaceutical, food, agrochemical, and cosmetics industries and involves a growing market of hundreds of billions of dollars. However, most chemical processes used for their production are not environmentally friendly because in most cases, stoichiometric amounts of chiral inductors are used and substantial waste is produced. In this context, asymmetric catalysis has emerged as an efficient tool for the synthesis of enantiomerically enriched compounds using chiral catalysts. More specifically, considering the current scenario in the Brazilian chemical industry, especially that of pharmaceuticals, the immediate prospect for the use of synthetic routes developed in Brazil in an enantioselective fashion or even the discovery of new drugs is practically null. Currently, the industrial production of drugs in Brazil is primarily focused on the production of generic drugs and is basically supported by imports of intermediates from China and India. In order to change this panorama and move forward toward the gradual incorporation of genuinely Brazilian synthetic routes, strong incentive policies, especially those related to continuous funding, will be needed. These incentives could be a breakthrough once we establish several research groups working in the area of organic synthesis and on the development and application of chiral organocatalysts and ligands in asymmetric catalysis, thus contributing to boost the development of the Brazilian chemical industry. Considering these circumstances, Brazil can benefit from this opportunity because we have a wide biodiversity and a large pool of natural resources that can be used as starting materials for the production of new chiral catalysts and are creating competence in asymmetric catalysis and related areas. This may decisively contribute to the growth of chemistry in our country. (author)

According to the International Atomic Energy Agency (IAEA), a relatively significant number of radiological accidents have occurred in recent years mainly because of the practices referred to as potentially high-risk activities, such as radiotherapy, large irradiators and industrial radiography, especially in gammagraphy assays. In some instances, severe injuries have occurred in exposed persons due to high radiation doses. In industrial radiography, 80 cases involving a total of 120 radiation workers, 110 members of the public including 12 deaths have been recorded up to 2014. Radiological accidents in industrial practices in Brazil have mainly resulted in development of cutaneous radiation syndrome (CRS) in hands and fingers. Brazilian data include 5 serious cases related to industrial gammagraphy, affecting 7 radiation workers and 19 members of the public; however, none of them were fatal. Some methods of reconstructive dosimetry have been used to estimate the radiation dose to assist in prescribing medical treatment. The type and development of cutaneous manifestations in the exposed areas of a person is the first achievable gross dose estimation. This review article presents the state-of-the-art reconstructive dosimetry methods enabling estimation of local radiation doses and provides guidelines for medical handling of the exposed individuals. The review also presents the Chilean and Brazilian radiological accident cases to highlight the importance of reconstructive dosimetry. (author)

Radiation in industrial processes

International Nuclear Information System (INIS)

1959-01-01

The uses of ionizing radiation can be divided into two broad categories. First, it can be used as a tool of investigation, measurement and testing, and secondly, it can be a direct agent in inducing chemical processes. For example, radiation can help in the detecting and locating of malignant tumours, and it can be employed also for the destruction of those tumours. Again, it can reveal intricate processes of plant growth and, at the same time, can initiate certain processes which result in the growth of new varieties of plants. Similarly in industry, radiation is both a tool of detection, testing and measurement and an active agent for the initiation of useful chemical reactions. The initiation of chemical reactions usually requires larger and more powerful sources of radiation. Such radiation can be provided by substances like cobalt 60 and caesium 137 or by machines which accelerate nuclear particles to very high energies. Of the particle-accelerating machines, the most useful in this field are those which accelerate electrons to energies considerably higher than those possessed by the electrons (beta particles) emitted by radioactive substances. These high-energy radiations produce interesting reactions both in organic life and in materials for industry. Several of the papers presented at the Warsaw conference were devoted to the application of ionizing radiation to polymerization and other useful reactions in the manufacture and treatment of plastics. The polymerization of the ethylene series of hydro-carbons was discussed from various angles and the technical characteristics and requirements were described. It was pointed out by some experts that the cross-linking effect of radiation resulted in a superior product, opening the way to new applications of polyethylene. Irradiated polyethylene film has been sold for several years, and electrical wire has been made with irradiated polyethylene as the insulating jacket. Other reactions discussed included the cross

Similar to all industrial activities utilizing radiation sources, or dealing with radioactive materials in its operations, petroleum industry requires the organization of a Radiation Emergency Plan. This plan should be based on a comprehensive and subtle understanding of the extensive multidisciplinary operations involved in petroleum processing and the dangers that threaten human health, environment and property; both from ordinary emergency situations common to petroleum industry activities and also from radiation emergency events. Radiation emergencies include radiological source accidents involving occurrence of high dose exposures. Radioactive contamination or spill are also major problems that may cause low dose exposures and environmental radioactive contamination. The simultaneous occurrence of other industrial emergency events such as fires or structural collapses will add to the seriousness of the emergency situation. The essential aspects of Radiation Emergency Planning include notification, assessment of situation, foresight, definition of roles and responsibilities including health safety and environmental concepts. An important contribution to the Emergency Planning is the proper intelligent medical response. Another essential parameter is the training of personnel that will undertake the responsibility of executing the emergency procedures according to the various emergency situations. The main features of the radiation Emergency Plan in Petroleum industry is presented in the text

Radiation processing: a versatile technology for industry

Soon after the discovery of x-ray in 1895 and radioactivity in 1896, it was recognized that ionizing radiation can modify the chemical, physical and/or biological properties of materials. However, it was only in the late 50's, when large radiation sources become available, has this unique property of radiation found industrial applications in radiation processing. Today, radiation processing has been used by industry in such diverse applications, such as radiation sterilization/decontamination of medical products, pharmaceuticals, cosmetics and their raw materials; radiation cross-linking of wire and cable insulation; production of heat shrinkable materials and polymer foam; and radiation curing of coatings, adhesives and inks on a wide variety of substrates. In addition to being a clean environment-friendly technology, radiation processing can also be used for the conservation of the environment by such processes as radiation treatment of flue gases to remove SO 2 and NO x and disinfection of sewage sludge. Because of the many advantages offered by radiation processing, industry is showing strong interest in the technology as evidenced by the growing number of industrial radiation facilities in many countries.

The cement industry is characterized by intensive energy consumption throughout its production stages which, together with the calcination of its raw materials, accounts for significant amounts of greenhouse gases (GHG) emissions. In 1996, the Brazilian cement industry consumed 4.3% of the energy required by the industrial sector, contributing over 22 Mtons (Million of tons) of CO 2 . The prospects for growth in this sector in Brazil indicate rising demands for fossil fuels, with a consequent upsurge in emissions. The purpose of this article is to present the prospects for energy conservation in the Brazilian cement industry through to 2015, taking into account the introduction of new production technologies in this sector, the use of waste and low-grade fuels, cogeneration, the use of additives, and other measures, based on a technical and economic energy demand simulation model

Industrial Gammagraphy plays an important role in the quality control of various materials and components. It is classified by the International Atomic Energy Agency - IAEA as Category 2, due to its radiation risk caused by the use of high activity radioactive sources. This risk is based on the harmful consequences of human health, described in some accidents in the world, due to failures. In 2012, the 'Brazilian National Workshop on Accident Prevention in Industrial Gammagraphy' was carried out by DIAPI/CNEN, with the objective of disseminating knowledge about radiation accidents. At the time, the IRD/CNEN-RJ carried out a survey with the 75 participants using a form with 22 recommendations to prevent radiological accidents, in order to select the 10 most voted. A statistical study, using the 'Frequency Distribution' method, was performed to define 10 recommendations. The percentage and vote results were obtained by category of the participants and the 10 most important recommendations were defined to prevent radiation accidents. The recommendation that came in first place was 'Always use an individual monitor with alarm during all work'.

Patterns of energy use in the Brazilian economy: Can the profile of Brazilian exports determine the future energy efficiency of its industry?

International Nuclear Information System (INIS)

Machado, G.V.; Schaeffer, R.

1997-01-01

This study examines the integration of the Brazilian economy in the global economy as a determining factor for the energy efficiency of its industry. Depending upon the profile of a country's exports (i.e., depending upon the share of energy-intensive exports out of total exports), different quantities of energy are required to produce the country's exported goods, which may counterbalance efforts made elsewhere to improve the overall energy efficiency of the country's industry. Different scenarios for the energy embodied in the industrial exports of Brazil are considered for the period 1995--2015. These scenarios are a combination of different shares of energy-intensive goods in the total exports of the country with different assumptions for gains obtained in industrial energy efficiency over time. For all scenarios the same fundamental hypothesis of liberalization of commerce and economic growth are assumed. Results for the year 2015 show that the total energy embodied in industrial exports varies from 1,413 PJ to 2,491 PJ, and the total industrial use of energy varies from 3,858 PJ to 6,153 PJ, depending upon the assumptions made. This is equivalent to an average industrial energy intensity variation ranging from 13.8 MJ to 22.0 MJ per US$-1985. The authors conclude that any policy aimed at improving Brazil's overall industrial energy efficiency should concentrate not only on the reduction of the energy intensity of particular industrial sectors, but also (and, perhaps, more importantly) on rethinking the very strategy for the integration of the country's economy in the global market in the future, with respect to the share of energy-intensive goods out of total exports. The focus is not incidental, for the ongoing structural changes in Brazilian exports alone may come to offset any efficiency improvements achieved by the national industry as a whole

A study about the industrial radiography situation in Brazil, concerning to the radiation protection aspects is shown. With this purpose it was made an inventory, with utilization of the file of facilities officially registered in industrial application from Brazilian Nuclear Energy Commission (CNEN). It was evaluated the quantity of accelerators, radiation monitors and radiation workers (health physics, operator). As quality and performance indicators of radiation protection the mean doses and the collective doses were used, and their variation from 1987 to 1990. As deficiency signals of radiological protection programs and procedures were utilized the 175 abnormal event occurred (radiological accident and emergency situation) from 1976 to 1992, after an analysis of their causes. The results showed that, for around 2000 monitored workers, the mean dose equivalent was between 0.83 to 2.70 mSv, and the collective dose, between 1.54 and 6.18 Sv.man, from 1987 to 1990. In this period, it was verified a tendency for reduction of means dose and collective dose values. It indicates a possible improvement of radiation protection services or an influence of economical situation of the country. From 175 abnormal events analysed, 456 persons were exposed, with 7.2% of them receiving doses above 50 mSv. These results were compared with those from others countries, such as United Kingdom and united States. (author). 76 refs, 16 figs, 24 tabs.

For the last 20 years, countless countries have been carrying out structural reforms in the natural gas industry, trying to achieve efficiency and economic rationality with the introduction of competition. The objective of the paper is to present an approach to the development of competition and infrastructure of the Brazilian natural gas industry. This approach is based on a market projection to 2011, on the international experience and on the characteristics of the Brazilian market, infrastructure and regulatory framework. Possible impacts of the proposed measures are also provided. According to the market projection carried out in this paper, in 2011 there will be a possible surplus of natural gas in the country, which includes a dependence diminishing of the Bolivian gas supply. This gas surplus, allied to an upcoming Gas Law and the trade liberalization in the states of Sao Paulo and Rio de Janeiro, can stimulate the development of competition, if some changes that proposed in this paper are made in the current Gas Bills. The approach proposed herein seeks to stimulate non-discriminatory open access, focused on information transparency and tariff regulation to help the development of infrastructure and competition.

Radiation protection and safety in industrial radiography

International Nuclear Information System (INIS)

1999-01-01

The use of ionizing radiation, particularly in medicine and industry, is growing throughout the world, with further expansion likely as technical developments result from research. One of the longest established applications of ionizing radiation is industrial radiography, which uses both X radiation and gamma radiation to investigate the integrity of equipment and structures. Industrial radiography is widespread in almost all Member States. It is indispensable to the quality assurance required in modern engineering practice and features in the work of multinational companies and small businesses alike. Industrial radiography is extremely versatile. The equipment required is relatively inexpensive and simple to operate. It may be highly portable and capable of being operated by a single worker in a wide range of different conditions, such as at remote construction sites, offshore locations and cross-country pipelines as well as in complex fabrication facilities. The associated hazards demand that safe working practices be developed in order to minimize the potential exposure of radiographers and other persons who may be in the vicinity of the work. The use of shielded enclosures (fixed facilities), with effective safety devices, significantly reduces any radiation exposures arising from the work. This Safety Report summarizes good and current state of the art practices in industrial radiography and provides technical advice on radiation protection and safety. It contains information for Regulatory Authorities, operating organizations, workers, equipment manufacturers and client organizations, with the intention of explaining their responsibilities and means to enhance radiation protection and safety in industrial radiography

Brazil has been recording declines in footwear exports; in 2011 there was an average reduction of 21.5% compared to 2010. Thus, Brazil has moved to the eighth position in the export market. Moreover, Asians have been improving the quality and technological level of their footwear for niche markets. It is well known that the introduction of new technologies into industrial organizations enables adding value to their products, making the organizations more competitive in the global market. In this work, we present a study on the use of radioscopy technique to improve quality control of the Brazilian footwear industry. Being already used by some international footwear manufactures, aiming at the identification of strange bodies, control jumps, among other aspects, this technique brings innovation to the referred industry, since it is a non-destructive test approach that makes use of X-rays. We also propose a tool for the application of radioscopy technique to improve quality control processes of footwear production, employing concepts of Failure Modes and Effects Analysis (FMEA).

Innovation subject to sustainability: the European policy on biofuels and its effects on innovation in the Brazilian bioethanol industry

Directory of Open Access Journals (Sweden)

Henrique Pacini

2012-08-01

Full Text Available Biofuels are a suitable complement for fossil energy in the transport sector and bioethanol is the main biofuel traded worldwide. Based on the assumption that innovation can be influenced by regulation, the Brazilian bioethanol industry is facing new requirements from external actors while reaching for international markets. Until 2010, national environmental laws were the main sustainability instrument that the biofuel industry faced. With the introduction of sustainability criteria for biofuels in the European Fuels Quality Directive (FQD and Renewable Energy Directive (RED of 2009, bioethanol producers have been pressured to innovate in respect of the requirements of future markets. Here, the aim is to analyse the case of Brazil, given the potential exports of sugarcane-based ethanol from this country to the EU. Brazil provides an interesting overview of how a bioethanol industry innovated while facing sustainability requirements in the past. A comparison between the European requirements and the industry´s status quo is then explored. The EU criteria are likely to have effects on the Brazilian bioethanol industry and incremental improvements in sustainability levels might take place based on the sustainability requirements. In addition, the industry could follow two other paths, namely risk diversification by engaging in multi-output models; and market leakage towards less-regulated markets. At the same time, an environmental overregulation of the biofuel market may make it more difficult for emerging biofuel industries in other countries, especially in Africa, by creating a barrier rather than contributing to its expansion. The results of this analysis show the main challenges to be addressed and the potential positive and negative impacts of the European Union biofuels policy on the Brazilian bioethanol industry.

In Brazil, the applications of ionizing radiation in industry are accomplished about 900 radioactive facilities, which handle approximately 3.000 radiation sources. The control of radioactive sources used in industrial installations authorized by the Brazilian Nuclear Energy Commission (CNEN) is accomplished by Servico de Radioprotecao na Industria Radiativa (SERIR) of the Instituto de Radioprotecao e Dosimetria (IRD), Rio de Janeiro, RJ, Brazil. This service carries out regulatory inspections in the practices of industrial radiography, nuclear gauges, industrial irradiators and oil wells logging. The frequency of inspections depends on the type of practice, ranging from a year to 5 years, depending on the risk involved. This paper presents a brief description of the situation of radiation safety in the use of radioactive sources in the industries of the country. The results obtained with regulatory inspections at industrial installations demonstrate that the conditions of safety and radiation protection in these facilities are satisfactory when compared with the technical regulations, both national and international

The Industrial Gamma Radiography, as part of Industrial Radiography, stands out as the most widespread and plays an important role in the quality control of different materials and devices. However, IAEA classifies industrial gamma radiography in the Category 2 as very dangerous due to the radiological risk caused by the use of high activity radioactive sources. In March, 2012, a Brazilian Workshop on Prevention of Industrial Gamma Radiography Accident was performed by DIAPI/CNEN with the objective of disseminating knowledge about radiological accidents with radioactive sources in this application. During this Workshop, IRD/CNEN conducted a survey with 75 participants using a form with 22 recommendations to prevent radiological accidents, aiming to select the most voted. This present work aims to perform a detailed statistical study to define the Top 10 Recommendations for industrial gamma radiography operator avoids radiological accidents and to prepare a brochure with these top 10 recommendations to be distributed to all industrial gamma radiography radiation workers. Data analysis was performed using the statistical method 'Frequency Distribution', among the 75 participants categorized as General, RPO, and Other Workers of the area. The results were obtained for each category, accounting for the total of 22 recommendations in its percentage and number of votes, and the top 10 recommendations were defined to prevent radiological accidents. The first place and most important recommendation is 'Always use a personal alarm monitor throughout the work'.

This work describes the ideas that guided the training in radiation protection and the first results obtained in the first half of 2004. The training took place in the Uranium Concentrate Unit URA, in Caetite, BA, in the Ore Treatment Unit - UTM, in Caldas, MG, and in the Heavy Mineral Unit - UMP, in San Francisco de Itabapuana, RJ, Brazil. In URA it was spent 9 days. 79 students were trained in 6 classes (average 13 pupils per class). Each group spent 9 hour of training, for a total of 54 hours of training given. There was no disapproval, and the grade average of the students was 9.2, with the lowest grade 7.5 and the highest 10.0. In UTM, it was spent 9 days. 200 students were trained in 9 classes (an average of 22 students per class). Each class spent 9h of training, totaling 81 hours. There were 18 deprecations, due to the the lack of education of the students. The overall average of the grades was 8.8, with lower note zero and higher 10.0. In UTM 158 people were trained in 5 classes, with an average of 31 students per class.It is concluded that in classes with few students (7 to 12) there were few parallel discussions. In classes with many students (over thirty) there was a scattering of ideas, which interfered in the progress of training. As proposal for upcoming classes can be suggested an average 20 people per class. The division of classes in groups working together was beneficial, giving a unit, which allowed greater freedom in questions, increasing parallel content taught. The classes have evaluated positively the initiative of the work done, which will be extended to other units of DRM, and subsequently all of the INB - Brazilian Nuclear Industries

Radiation technology in emerging industrial applications. Proceedings

In many industrial applications radiation processing has proven to be a technology of choice either because of its economic competitiveness or its technical superiority. Although the chemical effects of ionizing radiation have been known for more than a century, its industrial applications became possible only after the availability of reliable gamma sources and powerful electron accelerators during the last couple of decades.The programmes of the International Atomic Energy Agency (IAEA) in radiation processing are implemented through the Department of Nuclear Sciences and Applications and the Department of Technical Co-operation. The IAEA has been active in this field for many years, contributing to new developments, training, promotion and transfer of technology. In September 1997, the IAEA held an international symposium in Zakopane, Poland on the 'Use of radiation technology for the conservation of environment' where the status of current developments and of applications of radiation processing in the control of environmental pollution was reviewed (IAEA-TECDOC-1023, 1998). Recent developments and achievements in various aspects of radiation processing have been assessed continuously through the organization of consultants meetings, advisory group meetings and research co-ordination meetings. Worldwide growing interest in the use of radiation technology in various new industrial applications, as exemplified by the reports and presentations made at these meetings, has led the IAEA to organize a symposium to cover every aspect of radiation processing and, exclusively, the emerging industrial applications of radiation technology. The International Symposium on Radiation Technology in Emerging Industrial Applications was convened in November 2000 in Beijing, China. Its main purpose was to bring scientists,technologists, industrialists and regulatory authorities together with a view of exchanging information and reviewing the status of current developments and

The use of large isotopic radiation sources and accelerators in industry is reviewed. The advantages of various sources of ionizing radiation are indicated, and the development and present status of radiation technology are briefly described. Attention is given to the role played by radiation processing in the cross-linking of polymers as applied to cable insulation, artificial limbs and packaging materials, as well as for improving natural rubber. In addition, attention is given to radiation as a possible means of synthesizing polymers, of hardening non-conventional coatings and of manufacturing polymer-wood composites, thereby improving the properties of softwoods. The possibility of improving natural fibres by means of radiation is discussed, and attention is given to the important role already played by radiation in the sterilization of medical products. Finally, reference is made to the role which radiation can play in reducing food spoilage, as well as in making sewage sludge suitable for agricultural purposes [af

Noturally occurring radioactive materials, abbreviated NORM, have been incorporated into the European legislative framework of radiation protection With Directive 96/29/Euratom. Title VII of this directive pointed out that radiation protection has to be applied to ''work activities not covered by Article 2 [1] within which the presence of natural radiation sources leads to a significant increase in the exposure of workers or of members of the public which cannot be disregarded from the radiation protection point of view''. This new legal framework resulted in challenges for non-nuclear industries which process, treat or otherwise handle natural radiation sources. The natural radiation sources in these industries differ from the man-made radiation sources used in technical applications of radioactivity. In the non-nuclear industry, large volumes of raw materials with generally low activity concentration are processed.

While dosimetry is not a radiation application, accurate dosage of radiation of utmost importance for all radiation applications. For both therapeutic and industrial applications it can be matter of life and death. For this reason, great efforts have been made to ensure that radiation dosages given to patients and used in all industrial applications are as near as possible to those prescribed. The World Health Organization (WHO) and the IAEA, together with many National Standard Laboratories and with the International Bureau of Weight and Measures, have been very active and successful during the last 20 years in ascertaining that normal cobalt-60 therapy unit. For this purpose, 63 Secondary Standard Dosimetry Laboratories have been established of which more than half are in developing countries. FRPS houses one of the Secondary Standard Dosimetry Laboratories. As accurate dosimetry is a prerequisite in radiotherapy, so it is in industrial exposures and all laboratories responsible for dosimetry have to make frequent intercomparisons with one of the Primary Standard Dosimetry Laboratories. The SSDL at FRPS hopes to commence this as soon as our new Harshaw 6600 TLD reader arrives. This has already been approved by the IAEA. Much high doses of radiation are used for some industrial applications, as discussed in a previous lecture, such as sterilization of rubber, and food preservation and newly developed techniques are being used for the assurance of the prescribed dose. IAEA provides assistance in this area also through the secondary standard dosimetry laboratories. The IAEA has a broad programme of assistance which includes the calibration of all instruments in the laboratories of the participants, be it for radiation protection, or high dose measurements

The Brazilian Nuclear Energy Commission (cnen) has been making a constant effort to keep up to date with international standards and national needs to strengthen the status of radiological protection of the country. The guidelines related to radiation therapy facilities have been revised in the last five years in order to take into consideration the most relevant aspects of the growing technology as well as to mitigate the accidents or incidents observed in practice. Hence, clinical dosimeters have gained special importance in this matter. In the present work, we discuss the effectiveness of regulation and inspections to the enforcement of instrument calibration accuracy for the improvement of patient dosimetry and quality control. As a result, we observed that the number of calibrated instruments, mainly well chambers, is increasing each year. The same behavior is observed for instruments employed in technologically advanced radiation treatments such as intensity modulated radiotherapy, volumetric therapy and stereotatic radiosurgery. We ascribe this behavior to the new regulation.

Application of radiation in industry, medicine and research sector has increase significantly over the years. In industry main applications are industrial radiography, industrial fluoroscopy, radiation processing, luminizing, nucleonic gauges. Since the strength of the source used is generally high compared to other applications as well as the operating conditions prevailing during the exposure, radiological protection plays important role in this sector. Analysis of dose data, available with National Occupational Dose Registry of RPAD, Bhabha Atomic Research Centre, provides some insight into trends in occupational exposures received by industrial radiation workers. This helps in providing information on adequateness of radiation protection practices followed in the industry. This paper presents the trends in occupational exposure received by radiation workers in the industry during past 10 years (1999 to 2008). It is observed that there is a gradual increase in the occupational radiation workers during the period. The number of persons monitored as well as exposed is highest in industrial radiography compared to other sub-categories. Major contribution to collective dose is also from industrial radiography. The highest annual average as well as exposed average doses are contributed by industrial radiography. The monitored persons receiving dose d 5 mSv is 96.9% industry

Radiation sources are used in various industrial applications like industrial radiograph, industrial irradiation, industrial fluoroscopy, nucleonic gauges, well logging etc., Gamma, beta X-ray as well as neutron sources are used for various applications. Number of radiation workers in this field has increased over the years. Due to operating conditions prevailing during the exposure as well as the strength of the sources used in some of the applications, radiation protection plays an important role in this field. Analysis of doses received by radiation workers in industry provides information on trends of doses as well as adequateness of radiation protection practices followed in this sector. In India, National Occupational Dose Registry System (NODRS) of Radiological Physics and Advisory Division (RPAD), Bhabha Atomic Research Centre (BARC) maintains personnel dose information of monitored radiation workers in the country. Analysis of occupational dose data of industrial radiation workers for last 10 years, i.e., 1999-2008 has been presented in this paper. It is observed that even though there is an increase in monitored radiation workers, percentage of persons receiving radiation exposure has come down during this period. There is also a decrease in the average annual dose as well as the collective dose. Further analysis of sub-categories shows that industrial radiography operations are the main contributor for collective dose (about 77%) followed by well logging and industrial X-ray operations (about 8% each). Thus, in addition to industrial radiography attention is also to be given to operations in these areas. (author)

The oil and gas industry uses many radiation sources in various radiation based technologies which are of great benefit to the industry, this includes nucleonic gauges, multiphase flow meters, well logging etc. Inappropriate use of these equipment and installations and uncontrolled activities associated with naturally occurring radioactive materials (NORM) can contaminate the environment resulting in occupational and public exposures. The objective of this work is to develop a Radiation Protection Programme (RPP) for the oil and gas industry which when implemented by the operating organisation will keep doses to the workers and public as low as reasonably achievable (ALARA), maximize the benefits while minimizing the hazards associated with the use of radiation based technologies. In order to achieve the aim of this work, review of previous works on radiation sources in nucleonic gauges, well logging and waste management processes of NORMs was carried out. Some recommendations were stated, which if strictly implemented would improve the scope of radiation protection in the oil and gas industries. (au)

Ionizing Radiation as an Industrial Health Problem

Ionizing radiation, first as x-rays, later in natural form, was discovered in Europe in the late 1890's. Immediate practical uses were found for these discoveries, particularly in medicine. Unfortunately, because of the crude early equipment and ignorance of the harmful effects of radiation, many people were injured, some fatally. Because of these experiences, committees and regulatory bodies were set up to study the problem. These have built up an impressive fund of knowledge useful in radiation protection. With the recent development of the peaceful uses of atomic energy, sources of radioactivity have appeared cheaply and in abundance. A rapidly growing number are finding industrial application. Because of their potential risk to humans, the industrial physician must acquire new knowledge and skills so that he may give proper guidance in this new realm of preventive medicine. The Radiation Protection Program of one such industry, the Hydro-Electric Power Commission of Ontario, is summarized. PMID:14105012

Experience of improving quality assurance in the Brazilian industry

The growing participation of local engineering companies and industry in nuclear power plant implementation programs is highly important to developing countries which have decided for such programs. This participation is quite necessary and important on a political, economic and operational basis. Politically, two aspects should be taken into account; firstly, no country should develop a large and unforeseable dependence upon foreign sources for its power supply, and secondly, services and supplies which can be provided locally should not be purchased abroad. Regarding to the economic aspects, it would be very difficult to import complete nuclear power plants, taking into account the limited foreign currency unavailability to the country. As for the plant operation, if one considers the need for maintenance and repair throughout plants service life time, it would not be wise to have to fall back on foreign supply whenever a problem arises in a plant. This paper deals only with local industry participation in the construction of nuclear power plants. The first and foremost actions to be taken toward such participation should be identifying those industrial companies which have potential qualifications to participate in the construction program, and detecting the difficulties and shortcomings which must be overcome for the qualification of the various industrial companies. The difficulties for local industry participation are mainly of economic and technical nature. Economic difficulties refer to economy of scale and the amount of investments to be made by the industry in order to become qualified to participate in the program. These issues are connected with the cost of equipment to be manufactured and therefore with plant cost. As regards to the technical difficulties to be faced one has to consider the know-how for technical specifications and standards, product engineering, manufacturing procedures and above all quality assurance.

More than 30 years have passed since the starting up of nuclear industry in China from the early 1950's. Over the past 30-odd years, nuclear industry has always kept a good record in China thanks to the policy of 'quality first, safety first' clearly put forward for nuclear industry from the outset and a lot of suitable effective measures taken over that period. Internationally, there is rapid progress in radiation protection and nuclear safety (hereafter refereed to as radiation safety) and a number of new concepts in the field of radiation protection have been advanced. Nuclear industry is developing based on the international standardization. To ensure the further development of nuclear utility, radiation safety needs to be further strengthened

Prospect of radiation application in industry and agriculture

The prospect of radiation application in industry and agriculture are described. In industry, the radiation-induced crosslinking of polymers and radiation-induced graft polymerization improved many chemical and physical properties and new functional materials were created using ion beams. In agriculture, the food irradiation improved the food hygiene and killed insect pest of fruits and vegetables. Furthermore, the sterile insect technique, mutation breeding of plants, positron imaging system for plant, sterilization of medical products, environmental conservation due to purification of flue gas and wastewater, and upgrading of natural polymer (polysaccharide etc.) have been performed. Radiation process is a clean one without use of chemical reagents. The electron beam radiation is expected to reduce the cost of radiation process compared with the gamma-ray radiation. (M.H.)

Overview of Industrial Synchrotron Radiation Use

Science.gov (United States)

Laderman, Stephen S.

1996-03-01

Relevant, reliable and accessible synchrotron radiation methods can play an important role in industrial activities. To date, the application of synchrotron radiation based materials characterization methods by industrial concerns has followed the path of laboratory based x-ray methods: early adoption, continuous improvement, and a high degree of specialization to meet specific goals, which may change over time. Like all x-ray methods, their applicability to segments of the biotechnology, chemical, electronics, medical and metallurgical industries arises from a need to develop sophisticated processes for precisely controlling microstructures. An increasing number of those processes are being developed in ways which can, in principle, be more effectively studied if synchrotron radiation based analyses are performed. Technical limitations confined the efforts of early synchrotron radiation users to long-range research investigations. Nowadays, progress in data collection methods, analysis algorithims, accelerator performance, and worker training, have removed many constraints. However, commercial technologies are being improved at steadily higher rates, shortening the time between research, development and manufacturing and, in many cases, blurring their distinctions. Certainly, rapid rates of innovation increase the opportunities for synchrotron radiation techniques to bring competitive advantage since they can be used to shrink development times, to maintain yields and, perhaps, as part of advanced manufacturing. At the same time, rapid rates of innovation also impose stringent criteria on the reliability and timeliness of the supporting methods. Successful conventional x-ray methods have resulted from efforts to create useful new capabilities that effectively balance such forces. Currently, synchrotron radiation users throughout the world are pursuing analogous goals.

The transfer of research and development achievements of radiation processing to routine industrial applications in China is reviewed. While making a brief survey of historical background, the paper indicates the different roles that various domestic organizations played in the industrialization drive of radiation processing. Among them the Government's role is the most important one. In accordance with recent growth of the number of industrial radiation facilities (e.g. cobalt-60 irradiators and electron beam accelerators) and current application of radiation processing in main fields in different parts of the country, it can be said that a new radiation processing industry is shaping up in its developing stage to satisfy the growing requirements for economic booming in China.

Applications of radioisotopes and radiation technology are contributing significantly in many areas of science and technology, industry and environment, towards sustainable development, improving the quality of life and cleaner and safer national industries. There are three major classes impacting industrial scale operations, namely, (a) radiation processing/treatment, (b) radiotracer and sealed source techniques to monitor industrial processes/columns/vessels and (c) industrial gamma radiography and tomography. Radiation processing applying gamma sources and electron accelerators for material treatment/modification is an established technology. There are over 160 gamma industrial irradiators and 1300 industrial electron accelerators in operation worldwide. Development of new materials, especially for health care and environment protection, and advanced products (for electronics, solar energy systems, biotechnology etc) are the main objectives of R and D activity in radiation processing technology. The International Atomic Energy Agency (IAEA, Agency) is involved in supporting both the development and transfer of radiation technology. Thanks to Agency's efforts, advanced radiation processing centres have been established in many Member States (MS), e.g. Malaysia, Egypt, Iran, Poland, Brazil, Hungary. Hydrogel dressing for wounds, radiation vulcanised latex, degraded natural polymer are examples of useful product outcomes. Demonstration of effective treatment of flue gas in pilot plant as well as industrial scale and industrial wastewater in pilot plant scale has shown promise for tackling industrial emissions/effluents using electron beam machines. Industrial radiotracer and gamma sealed source techniques are largely used for analyzing industrial process systems. Initially used as trouble-shooting measures, they play a vital role in process parameter optimization, improved productivity, on-line monitoring and could lead to even pre-commissioning benchmarking.

This paper analyzes the macroeconomic impacts of the investments in the oil and gas upstream, which took place after the reform of the Brazilian oil industry. The reason why I chose to analyze such a period of time was the institutional change which took place in the Brazilian oil industry after the Brazilian Parliament approved Law n. 9.478 in 1997. The law represented the new regulation of the activities related to the oil industry in Brazil. Since then, there has been a very large amount of capital spending in the oil and gas upstream, not only by PETROBRAS, the state-owned oil company, but also by the oil companies which entered the Brazilian oil industry after it was opened to foreign and private upstream investments. This paper analyses the economic impacts of these upstream investments by PETROBRAS and by the new players in Brazil, addressing the impacts of these investments on the generation of aggregate value and yield and the economic activity of other industries. This paper is dedicated, in its entirety, to Prof. Carmen Alveal, whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally. (author)

Challenges and technological opportunities for the oil refining industry: A Brazilian refinery case

International Nuclear Information System (INIS)

Castelo Branco, David A.; Gomes, Gabriel L.; Szklo, Alexandre S.

2010-01-01

The worldwide oil refining industry currently faces strong challenges related to uncertainties about future feedstock and characteristics of oil products. These challenges favor two main strategies for the sector: the first strategy is increasing refinery complexity and versatility; the second is integrating the refining and petrochemical industries, adding value to the crude oil while guaranteeing market share to premium oil products. Both strategies aim at increasing production of highly specified oil products, simultaneously reducing the environmental impacts of the refining industry. This paper analyses the case of a Brazilian refinery, Gabriel Passos Refinery (REGAP), by proposing additional investments to alter and/or expand its current production scheme. All the proposed options present relatively low investment rates of return. However, investments in a hydrocracking based configuration with a gasification unit providing hydrogen and power can further improve the operational profitability, due to reduced natural gas consumption.

THE EIGHTH BRAZILIAN CONGRESS ON METROLOGY (METROLOGIA 2015) The United Nations celebrated 2015 as the International Year of Light. By a curious coincidence, many notable events in science and technology completed a multiple of 50 or 100 years in 2015. From the pioneering work of the wise Ibn Al-Haytham in 1015, through Fresnel, Maxwell, Einstein, the discovery of the cosmic microwave background, to the use of optical fibres in communications in 1965. Electromagnetic radiation is present in our daily lives in countless applications. It is remarkable that there is no way to think about these applications without thinking of measurements. From entangled photons to more prosaic public illumination of our daily life, we are intrinsically connected all the time with the luminous phenomena. Among other things, the light allows global communication on a large scale. It strengthens the internationalization of production processes, which brings considerable changes in relations, processes and economic structures, as well as it orients the social, political and cultural behaviour of any country. These conditions of this internationalization require interchangeability of parts of complex systems, translated into strict adherence to the standards and specifications that use increasingly accurate measurement techniques, as well as the growing demand from consumer markets for products and higher quality services. They also require innovation and improvements in domestic production to boost the competitiveness of industries in domestic and foreign markets. Thus, if the Science of Measurements is taken as a serious concern, countries are better prepared to evolve towards economic and social development. In this 8"t"h edition of the Brazilian Congress on Metrology (METROLOGIA 2015), in addition to the thematic sessions in various areas of Metrology and Conformity Assessment, we hold several satellite events.

Full Text Available This study aims to offer a model to apply the VMI to manage purchasing and inventory in the Brazilian footwear industry as this industry’s is inserted in a rising product diversity environment, with shorter product lifecycle while facing heavy, international competitive pressures. The model that is being proposed is also related to establishing minimum inventory levels and the ideal inventory replenishment cycle for industrial operations, and it also classifies materials according to their financial impact and to how critical their provision is. This research, which is defined as an exploratory and qualitative one, addresses a case study of a Brazilian footwear company to gather fundamental information associated with operations history, strategic operational characteristics in the purchasing area, and purchasing management systems, all performed by means of an in-depth interview. When data was analyzed, it showed that among the various materials used by a footwear company, the use of VMI would be needed for materials that were classified as being non-critical components and competitive components, that is, those with a low degree of uncertainty regarding to offer and both high and low financial impact, respectively.

Berejka, A.J.; Cleland, M.R.; Walo, M.

The evolution of industrial radiation processing is traced from Roentgen's discovery of X-radiation in 1895 by following the development of high current, electron beam accelerators (EB) throughout the twentieth century. Although Becquerel soon followed Roentgen with his discovery of what became to be known as radioactivity, electrical sources for ionizing radiation dominate industrial processing with there being more than ten times as many industrial installations using high current EB equipment than the facilities relying upon large concentrations of radioactive isotopes. In the 1950s, the discovery that ionizing radiation would enhance the value of what has become the world's largest volume commodity plastic, polyethylene (PE), opened the way for full scale commercial use of high current EB equipment. While the crosslinking of the PE insulation on wire became one of the first major industrial applications, other uses of EB processing soon followed. In the 1970s, low-energy, self-shielded EB equipment made the surface curing of inks, coatings and adhesives more industrially viable. In the early part of the twenty-first century, new market applications involving the low-energy EB surface decontamination of packaging materials emerged. This new area poses challenges for the metrology needed to control industrial processes, in that there is limited EB penetration into what have been used as dosimeters by industry. Major industrial use of radiation process is now over 50 years old. Because of the diversity of end-uses and the fact that the use of ionizing radiation in industry is a process technique, it is hard to quantify the value-added to numerous commercial products that benefit from this energy efficient process. It may be in excess of a trillion Euros in value-added to articles of commerce. In this milieu, there are some broad-based opportunities for research which are noted. - Highlights: ► The evolution of industrial radiation processing is traced from

Brazilian new patterns of an industrial, technological and foreign trade policy.

Directory of Open Access Journals (Sweden)

José Matias Pereira

2006-08-01

Full Text Available The objective of this paper is to deepen the discussion about the unavoidable way Brazil has to go through in order to construct a modern industrial and technological policy, based on knowledge and technological innovation, which will work as a stimulator of economic development. The different theories about this subject (SCHUMPETER, 1985; PAVITT, 1998; FREEMAN, 1995; KRUGMAN, 1995; COUTINHO & FERRAZ, 1994; MATIAS-PEREIRA & KRUGLIANSKAS, 2005, so as the principles set by the Brazilian Development Ministry (“Diretrizes de Política Industrial, Tecnológica e de Comércio Exterior”, give support in the search for defining a new model of industrial, technological policy and foreign trade for the country. The strategic role of industrial policy seems to be very evident, if it takes on its co-ordination work involving the productive agents, which are responsible for crucial decisions, such as those related to investments and/or innovation, in a context of great incertitude about the consequences of their decisions in the future. Finally, the conclusion arising from this discussion demonstrates that it is crucial for the country to define a modern industrial policy, which could be able to integrate the incentive to innovation as well as to exports, in order to serve as a tool to foster development. The paper also argues that the feasibility to this policy depends on Government’s ability in supplying agents with a favorable context towards adequate regulation, purchasing policy, availability on financing facilities and fiscal incentives.

Dietary pattern plays a causative role in the rising of noncommunicable diseases. The SESI (Serviço Social da Indústria) study was designed to evaluate risk factors for noncommunicable diseases. We aimed to describe food items consumed by Brazilian workers and to assess their association with socioeconomic status. Cross-sectional study was carried out among Brazilian industrial workers, selected by multistage sampling, from 157 companies. Interviews were conducted at the work place using standardized forms. 4818 workers were interviewed, aged 35.4 ± 10.7 years, 76.5% were men. The workers had an average of 8.7 ± 4.1 years of schooling and 25.4 ± 4.1 kg/m² of BMI. Men and individuals with less than high school education were less likely to consume dairy products, fruits, and vegetables daily, even after control for confounding factors. Men consumed rice and beans daily more often than women. In comparison to workers aged 50-76 years, those under 30 years old consumed less fruits and green leafy vegetables daily. The food items consumed by Brazilian workers show that there are insufficient consumption according to the guidelines of healthy foods, particularly of dairy products, vegetables, and fruits.

From research to industry - the establishment of a radiation processing industry in South Africa

International Nuclear Information System (INIS)

Du Plessis, T.A.; Stevens, R.C.B.

1983-01-01

In the late sixties the South African Atomic Energy Board in pursuing its objectives to promote the peaceful application of nuclear energy in general, established a research group with the specific purpose of investigating and developing radiation processing as a new technique. During the early years it was realised that the economic and technological facets of establishing a new industry were equally important and, in addition to fundamental research, strong emphasis was placed on the necessity of marketing this new technology. Although the initial emphasis was put on gamma sterilization, and today still forms the backbone of the radiation processing industry, the promising fields of polymer modification and food irradiation hold a lot of promise in the radiation processing industry. Following ten years of successfully introducing and providing a radiation service, the South African Atomic Energy Board in 1980 decided to transfer its service to the private sector. These developments in South Africa are a good sample of how a small country, through initial government involvement, can acquire a sophisticated new private industry. (author)

Catching up and Falling behind: An Appraisal of Brazilian Industrial Policy in the Twenty-First Century

Directory of Open Access Journals (Sweden)

Yuri Kasahara

2016-04-01

Full Text Available Amidst analyses of industrial policy’s renaissance in Latin America, Brazil is often hailed as the paragon of this movement. The mix of old and new institutions and instruments would constitute a unique effort in promoting industrial development in the post-neoliberal period. However, this experience has been followed by middling results of industrial performance. Reviewing an emerging literature about the institutionalization and results of the Brazilian industrial policy, we argue that important aspects of path-dependency have been ignored. Organizational and ideational resistance have led to a much more traditional and conservative industrial policy than would be expected. Grounded historical analysis about intra-government conflicts, combined with studies about policy and sectoral developments, could give us elements to better assess the failures and achievements of the Brazilian case. Resumen: Avances y retrocesos: Una evaluación de la política industrial brasileña en el siglo XXI A la luz de diversos análisis sobre el renacimiento de la política industrial en América Latina, Brasil es frecuentemente alabado como el país arquetipo de la mencionada coyuntura.

Radiation hazards in medicine, industry and education

Energy Technology Data Exchange (ETDEWEB)

Hone, C [Radiological Protection Inst. of Ireland (Ireland)

1996-10-01

Ionising radiation is widely used in medicine, industry and education. Most people are familiar with medical applications for diagnosis and treatment of disease. Industrial uses include: the measurement and control of various processes - e.g. liquid levels in bottling and canning plants and the thickness and density of a wide range of materials, the examination of metallic structures for defects and the sterilisation of medical products. Educational applications range from demonstrating the basic laws of radiation physics to sophisticated studies of chemical and biological processes using chemical compounds which have been labelled with suitable radioisotopes. Furthermore many pieces of laboratory equipment, for example X-ray diffractometers and X-ray fluorescence analyses, incorporate a source of radiation. The safety record of the use of radiation, when compared with many other industrial processes, is generally good. However, serious accidents can and have occurred. While most accidents involve small numbers of people, a few have had widespread consequences. These include accidents where large numbers of patients undergoing radiotherapy received the incorrect dose and where the inadvertent disposal and scrapping of radiation sources lead to widespread contamination of persons, property and the environment. This paper will discuss the hazards associated with particular applications and outline the causative factors identified. These include, equipment faults, simple but serious errors in dose calculations and loss or incorrect disposal of radioactive sources. The lessons that have, or should have been learned, from the past events are also considered. The paper describes the regulatory system in Ireland for controlling the use of radiation. The description shows how regulations are established within the framework of the European Commission Directives on radiation protection. (Abstract Truncated)

Serpa, Renata F.B.; Jesus, Edgar F.O. de; Lopes, Ricardo T.; Moreira, Silvana

2005-01-01

In order to identify major and trace elements in conventional and light Brazilian cigarettes, Total Reflection X-Ray Fluorescence with Synchrotron Radiation (SR-TXRF) was used. The fluorescence measurements were carried out at Brazilian Synchrotron Light Laboratory, Campinas - Sao Paulo. This technique enables detection limit is in the ngg -1 range, which is very useful in elemental tobacco smoke analysis, since it presents most of its elements at a trace level. The major elements identified in tobacco samples were: S, Cl, K, Ca, Mn, Fe and Cd, and the trace elements were: Ti, Cr, Ni, Cu, Zn, Br, Rb, Sr and Ba. However in tobacco smoke samples, there were only two major elements: K and Ca, the others were present a trace level. The rate transfer of tobacco to tobacco smoke was about 2.5 % for all elements studied. (author)

Listeria monocytogenes can cause listeriosis, a severe foodborne disease. In Brazil, despite very few reported cases of listeriosis, the pathogen has been repeatedly isolated from dairies. This has led the government to implement specific legislation to reduce the hazard. Here, we determined the incidence of L. monocytogenes in five dairies and retail products in the Southeast and Midwest regions of Brazil over eight months. Of 437 samples, three samples (0.7%) from retail and only one sample (0.2%) from the dairies were positive for L. monocytogenes. Thus, the contamination rate was significantly reduced as compared to previous studies. MultiLocus Sequence Typing (MLST) was used to determine if contamination was caused by new or persistent clones leading to the first MLST profile of L. monocytogenes from the Brazilian dairy industry. The processing environment isolate is of concern being a sequence-type (ST) 2, belonging to the lineage I responsible for the majority of listeriosis outbreaks. Also, ST3 and ST8 found in commercialized cheese have previously been reported in outbreaks. Despite the lower incidence, dairy products still pose a potential health risk and the occurrence of L. monocytogenes in dairies and retail products emphasize the need for continuous surveillance of this pathogen in the Brazilian dairy industry.

The industrial uses of ionizing radiation in Tunisia are expanding, especially in industry and most particularly in the nondestructive testing of welds. Thus workers operating in the non-destructive testing of welds may develop a radiation-induced cataract varying in time to onset depending on the dose. To describe the characteristics of the radiation-induced cataract in patients exposed to ionizing radiation, determine the risk factors of radiation-induced cataracts. This was an anamnestic, clinical, and environmental study of five cases of radiation-induced cataract in workers employed in non-destructive testing of welds. This series of five cases had a mean age of 30.2 years and 5.53 years of work experience, ranging from 14 months to 15 years. All the patients were male and industrial radiographers specialized in nondestructive testing of welds. The average duration of exposure to ionizing radiation was 5.53 years. None of the patients had worn protective gear such as eye goggles. The ophthalmic check-up for the five special industrial radiographers showed punctuate opacities in three cases, punctiform opacities in one eye in one case, and phacosclerosis with bilateral lens multiple crystalline stromal opacities in a case of micro-lens opacities in both eyes with opalescence of both eyes in one case. These cataracts had been declared as occupational diseases. The value of a specialized ophthalmologic surveillance among these workers and the early diagnosis of lens opacities must be emphasized.

Radiation protection, safety and associated problems in industrial radiography

International Nuclear Information System (INIS)

Le Roux, P.R.

1990-01-01

Industrial radiography is an indispensable tool for non-destructive testing. Its use entails potential radiation exposure to the operator as well as to the public. Since such radiation has the potential to be harmful, there is a need to limit radiation exposure to a level at which the risk is believed to be acceptable to the individual and to society. The Radiation Protection Society and the Department of National Health believe that the level of protection provided for radiation workers should be comparable with that in other 'safe' industries. The total risk for radiation workers includes the risk of non-radiation related accidents in the various occupations, as well as the special risks of radiation exposure. Industrial radiographers have one of the poorest safety records of all non-medical radiation workers. Operator errors and management errors seem to be the primary contributors to most accidental high exposures. It is necessary to remember that industrial radiography has to be carried out in a wide variety of work places under many different working conditions, both by day and by night. High energy end emissivity (X-ray output or source activity) is required for the radiation to be transmitted through specimens, because these are normally constructed of thick and dense materials such as steel. Additionally, most radiographic sources must be portable to permit use in field locations. On the negative side it must be mentioned that studies undertaken abroad conclude that the most important factors contributing to unsafe operations are human related. Careful planning of the method of work is essential if unnecessary risks are to be avoided. The most effective way of reducing accidents would seem to be to train employees to adhere to established and well documented procedures, to exercise common sense and sound judgement, and to use the protective equipment and devices provided in the manner specified. 2 tabs., 3 refs

Computational methods for industrial radiation measurement applications

Gardner, R.P.; Guo, P.; Ao, Q.

1996-01-01

Computational methods have been used with considerable success to complement radiation measurements in solving a wide range of industrial problems. The almost exponential growth of computer capability and applications in the last few years leads to a open-quotes black boxclose quotes mentality for radiation measurement applications. If a black box is defined as any radiation measurement device that is capable of measuring the parameters of interest when a wide range of operating and sample conditions may occur, then the development of computational methods for industrial radiation measurement applications should now be focused on the black box approach and the deduction of properties of interest from the response with acceptable accuracy and reasonable efficiency. Nowadays, increasingly better understanding of radiation physical processes, more accurate and complete fundamental physical data, and more advanced modeling and software/hardware techniques have made it possible to make giant strides in that direction with new ideas implemented with computer software. The Center for Engineering Applications of Radioisotopes (CEAR) at North Carolina State University has been working on a variety of projects in the area of radiation analyzers and gauges for accomplishing this for quite some time, and they are discussed here with emphasis on current accomplishments

The scientific linacs realized by CGR MeV in France have been installed in several research centers, the medical accelerators of CGR MeV have been installed in radiotherapy centers all over the world, and the industrial linacs have been used for radiography in heavy industries. Based on the experience for 30 years, CGR MeV has realized a new industrial radiation source for food processing. CARIC is going to install a new machine of CGR MeV, CASSITRON, as the demand for radiation increased. This machine has been devised specially for industrial irradiation purpose. Its main features are security, simplicity and reliability, and it is easy to incorporate it into a production line. The use of CASSITRON for food industry, the ionizing effect on mechanically separated poultry meat, the capital and processing cost and others are explained. Only 10 % of medical disposable supplies is treated by ionizing energy in France. The irradiation for food decontamination, and that for industrial treatment are demanded. Therefore, CARIC is going to increase the capacity by installing a CASSITRON for sterilization. The capital and processing cost are shown. The start of operation is expected in March, 1986. At present, a CASSITRON is being installed in the SPI food processing factory, and starts operation in a few weeks. (Kako, I.)

The radiation and radioisotope gauging industry in the United States has primarily followed a path of development solely by the private sector. It has remained highly proprietary in nature, which is opposite to the path taken by many other countries. In other countries radiation gauge development has been controlled in large part by government-sponsored research and development, which has spawned many more publications in the open literature. Historically, some of the leaders have been Great Britain, Poland, France, Russia, and Australia. This has possibly led to the misconception that the development of this technology is being dominated by countries outside the United States. This is not a healthy situation-it would be good to see our industry begin to publish more in the open literature and to sponsor more research at universities. In efforts to promote more open-literature publication, the American Nuclear Society (ANS) sponsored a topical meeting on Industrial Radiation and Radioisotope Measurement Applications (IRRMA) in 1988 that was held again in 1992

Radiation sterilization is widely applied in food processing, Pharmaceutical Manufacturing and medical instrumentation producing. As this industry offers service to related corporations, its development depends largely on the market scale of the relevant industries. This article mainly discusses the balance point between the capacity of radiation sterilization and the requirement of its market. There are less than 1% of the companies in Sichuan which using radiation sterilization for its products, broad prospects has shown in this field. The output value of radiation sterilization industry reached 0.1% of the GDP in some advanced countries (America and Japan...), under this standard, its output value in Sichuan province would be RMB1.2 hundred million, but now our capacity and scale of this industry is less than RMB40million.Research shows: there are 3 key points to make its output value reach 0.1% of the GDP in Sichuan: 1. Breaking the 'bottleneck' restrictions of capacity and Inappropriate resources distribution. 2. Promoting the technique of radiation sterilization, guiding corporation to reduce their dependence on food additive from the perspective of food safety, make effective implantation of radiation sterilization into their manufacture processes. 3. Increasing publicity for radiation sterilization, eliminating scared mentality among customer on nuclear technology, helping manufacturing corporations to establish green environmental protection brand, directing our customer to a more healthy awareness.

Promoting safety culture in radiation industry through radiation audit

International Nuclear Information System (INIS)

Noriah, M.A.

2007-01-01

This paper illustrates the Malaysian experience in implementing and promoting effective radiation safety program. Current management practice demands that an organization inculcate culture of safety in preventing radiation hazard. The aforementioned objectives of radiation protection can only be met when it is implemented and evaluated continuously. Commitment from the workforce to treat safety as a priority and the ability to turn a requirement into a practical language is also important to implement radiation safety policy efficiently. Maintaining and improving safety culture is a continuous process. There is a need to establish a program to measure, review and audit health and safety performance against predetermined standards. This program is known as radiation safety audit and is able to reveal where and when action is needed to make improvements to the systems of controls. A structured and proper radiation self-auditing system is seen as the sole requirement to meet the current and future needs in sustainability of radiation safety. As a result safety culture, which has been a vital element on safety in many industries can be improved and promote changes, leading to good safety performance and excellence. (author)

2015-11-01

Full Text Available MODIS images during the year 2012 were used for modelling of the radiation and energy balance components with the application of the SAFER algorithm (Simple Algorithm for Evapotranspiration Retrieving in the Brazilian Pantanal area. Pixels from the main sub-regions of Barão de Melgaço (BR, Paiaguás (PA and Nhecolândia (NH were extracted in order to process microclimatic comparisons. In general, the net radiation (Rn relied much more on the global solar radiation (RG levels than on water conditions and ecosystem types, in accordance with the low Rn standard deviation values. The fraction of the available energy used as latent heat flux (λE were, on average, 65, 50 and 49% for the BR, PA and NH sub-regions, respectively. Horizontal heat advection, identified by the negative values of sensible heat flux (H, made several pixels with λE values higher than those for Rn in the middle of the year. Taking the evaporative fraction (Ef as a surface moisture indicator, the Tree-Lined Savanna (TLS was considered the moister ecosystem class, with 58% of the available energy being used as λE, while the driest one was the modified ecosystem Anthropogenic Changes (AC, presenting a λE/Rn fraction of 0.46. According to the spatial and temporal consistencies, and after comparisons with other previous point and large-scale studies, the SAFER algorithm proved to have sensibility to quantify and compare the large-scale radiation and energy balance components in the different ecosystems of the Brazilian Pantanal. The algorithm is useful for monitoring the energy exchange dynamics among the different terrestrial and aquatic ecosystem types throughout the seasons of the year.

This study investigated the status of radiation exposure doses since the establishment of the 'Regulations on Safety Management of Diagnostic Radiation Generation Device' in January 6, 1995. The level of radiation exposure in people engaged or having been engaged in radiation-related industries of inspection organizations, educational organization, military units, hospitals, public health centers, businesses, research organizations or clinics over a 5 year period from Jan. 1, 2000 to Dec. 31, 2004 was measured. The 149,205 measurement data of 57,136 workers registered in a measurement organization were analysed in this study. Frequency analysis, a Chi-square test, Chi-square trend test, and ANOVA was used for data analysis. Among 57,136 men were 40,870 (71.5%). 50.3% of them were radiologic technologists, otherwise medical doctors (22.7%), nurse (2.9%) and others (24.1%). The average of depth radiation and surface radiation during the 5-year period were found to decrease each year. Both the depth radiation and surface radiation exposure were significantly higher in males, in older age groups, in radiological technologists of occupation. The departments of nuclear medicine had the highest exposure of both depth and surface radiation of the divisions of labor. There were 1.98 and 2.57 per 1,000 person-year were exposed more than 20 mSv (limit recommended by International Commission on Radiological Protection) in depth and surface radiation consequently. The total exposure per worker was significantly decreased by year. But Careful awareness is needed for the workers who exposed over 20 mSv per year. In order to minimize exposure to radiation, each person engaged in a radiation-related industry must adhere to the individual safety management guidelines more thoroughly. In addition, systematic education and continuous guidance aimed at increasing the awareness of safety must be provided

An overview of equivalent doses in eye lens of occupational radiation workers in medical, industrial and nuclear areas

International Nuclear Information System (INIS)

Lima, A.R.; Silva, F.C.A. da; Hunt, J.G.

2013-01-01

Some epidemiological evidences were recently reviewed by the ICRP and it was suggested that, for the eye lens, the absorbed dose threshold for induction of late detriments is about 0.5 Gy. On this basis, on 2011, the ICRP has recommended changes to the occupational dose limit in planned exposure situations, reducing the eye lens dose equivalent limit of 150 mSv to 20 mSv per year, on average, during the period of 5 years, with exposure not exceeding 50 mSv in a single year. Following the ICRP recommendation, the Brazilian Commission of Nuclear Energy (CNEN) adopted immediately the new limit to the eyes lens. This study aimed to show an overview about the doses in eye lens of occupational radiation workers in situations of planned exposures in the medical, industrial and nuclear areas, emphasizing the greatest radiological risks applications. It was observed that there are some limitations, such as example, to use individual monitor calibrated on Hp(3), to assess the equivalent dose in the eye lens. This limitation obstructs some experimental studies and monitoring of the levels of radiation received in the eye lens of radiation workers. Recent studies have showed that the lenses of eyes monitoring of workers, mainly in the planned exposure, must be follow-up. However, such researches were obtained only in medical exposures, mainly in interventional medicine procedures. Studies with planned exposure on nuclear and industrial areas are really needed and will be very important due to the new recommended by ICRP dose limits. (author)

Industrial radiography is one of the essential methods in the modern technology to guarantee the quality control of many types of devices, pieces and machines operation, and usually involves intense radiation sources, which can expose people at work to significant amounts of radiation. According to the reports of United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR 2000), the average occupational effective dose in this field is 3.37 mSv/y. The level of dose received by industrial radiographers was assessed in more than 1300 radiation workers in 120 industrial radiography companies. The level of radiation safety regulations and radiation protection programme implemented in Iranian industries was also studied. The results indicated that the average effective dose to the radiographers and collective effective dose are 1.65 mSv/y and 2.43 Man.Sv respectively. The results also showed that 88% of radiographers have received less than 5 mSv/y and only 1% received the annual dose more than 20 mSv. The lack of emergency instruction was found in 47% of companies and in 35% of companies there was not found any compatible emergency instrument. Suitable temporary storage and transportation facility was no also found in 30% of companies. Based on the results found in this study, the enforcement of the radiation protection low and industrial radiography code of practice for responsible persons and health physics officers are recommended.

Ionizing radiations: medical and industrial applications

International Nuclear Information System (INIS)

Vidal, H.

1994-01-01

Medical diagnosis with X-rays is the best known use of ionizing radiations on account of its wide diffusion (about 57 500 units in France). Other medical applications of artificial radionuclides involving a smaller number of installations are also well known, i.e. gamma teletherapy (167 units), brachytherapy (119 units) or therapy using unsealed sources (257 units). The industrial uses of ionising radiation, the diversity of which is very large, are generally less well known. The use of X- and gamma rays for non-destructive testing or food preservation and the use of tracers have some notoriety, but few people know that radioactive sources are involved in the measurement of parameters controlling industrial processes. The number of persons authorized to hold, use and/or sell artificial radionuclides amounts to about 4 800, all applications included. Approximately 650 of them are involved in therapy and 500 in medical research. The aim of this paper, which is not exhaustive, is to review a few typical applications of radionuclides both in the medical and industrial fields. It also supplies data both on the number of people authorized to use each technique and the radionuclides involved. (author). 10 tabs

International Nuclear Information System (INIS)

Federico, Claudio Antonio

2011-01-01

The objective of this work is the establishment of a dosimetric system for the aircrew in the domestic territory. A technique to perform measurements of ambient dose equivalent in aircrafts was developed. An active detector was evaluated for onboard aircraft use, testing its adequacy to this specific type of measurement as well as its susceptibility to the magnetic and electromagnetic interferences. The equipment was calibrated in standard radiation beams and in a special field of the European Laboratory CERN, that reproduces with great proximity the real spectrum in aircraft flight altitudes; it was also tested in several flights, in an Brazilian Air Force's aircraft. The results were evaluated and compared with those obtained from several computational programs for cosmic radiation estimates, with respect to its adequacy for use in the South American region. The program CARI-6 was selected to evaluate the estimated averaged effective doses for the aircrew who operate in this region. A statistical distribution of aircrew effective doses in South America and Caribe was made, and the results show that a great part of this aircrew members are subjected to annual effective doses that exceed the dose limits for the members of the public. Additionally, a preliminary passive dosemeter, based in thermoluminescent detectors, was proposed; international collaborations with United Kingdom and Italy were established for joint measurements of the ambient equivalent doses in aircrafts.

2010-07-01

Full Text Available This study aims to identify cases of new international ventures in the Brazilian sugarcane industry, specifically as regards ethanol production, i.e., companies that are established from start to have an international profile. The paper explores the case of one such enterprise in the light of the theories addressed. In the last few years, a rising number of companies with this profile have appeared. This runs contrary to the main classical theories of internationalization, which present this process as evolutionary. As for the sugarcane industry, it has expanded considerably in recent years, which led many groups to invest in this segment. This study is a descriptive, qualitative piece of research and is based on the case study of a company recently established in this sector. Analyzing the chosen organization and comparing it to the studied theories, the authors concluded that there is, indeed, a type of organization with the profile of a new international venture. Key-words: Internationalization. New international ventures. Sugarcane industry. Brazil.

In this account a new standardization system is described. This system is intended for the protection of environment, people and employees against the harmful consequences of ionizing radiation. This new system is based upon the actual knowledge of the harmful effects of ionizing radiation and joins to the starting points and objectives of the environment- and industry-protectional policies and is explained for both policies separately. The starting points and objectives are presented of the actual environment- and industry-protectional policies and of the radiation-protection policy pursued up till now. The harmful effects of radiation, the importance of the of the most recent scientific developments and the results of the investigation performed in the framework of this account, are described. Conclusions about these harmful affects are given. The systematics of the standardization are described. Subsequently are considered the radiation sources, their classification, the risk limits for regular situations and for large accidents, the justification principle and the ALARA-principle, emission- and product requirements, objectives for environment quality, standards for combat of the consequences of accidents, the policy with regard to 'building and dwelling' and finally standards for protection of employees. The consequences of the systematics of standardization, which are described in this account, are indicated for environment- as well as industry-protectional policy. Per radiation-source category the corresponding risks are indicated and at which term which continuation activities are necessary. The consequences for the set of instruments and some international aspects are considered. Finally the activity list gives a survey of the continuation activities and the terms at which these have to be carried out. (H.W.). 4 figs.; 1 tab

Kinda, R.

2013-04-01

Non-Destructive Testing employs a variety of techniques which are used to test objects e.g. pipes, vessels, welded joints, castings and other devices for imperfections without interfering with their physical structure. The common methods of testing include magnetic particle, ultrasound, dye penetrant and industrial radiography using gamma emitting radiation sources and electronic x-ray emitting devices. Other methods used are acoustic emission testing, acoustic resonance testing, electromagnetic testing, infrared testing and leak testing. This project work focuses on training of RPOs in the areas where radiation is used, as improper use may lead to high radiation exposure. In order to ensure adequate protection and safety of staff and the public, the Radiation Protection Officers need to be thoroughly trained. With proper training the Radiation Protection Officer will have the ability to interpret legislative instruments and understand the requirements. The RPO will also be able to develop a Radiation Protection Plan and train fellow staff on radiation safety issues. A number of companies currently specialize in Industrial Radiography and this number is growing on a yearly basis. Since the increased use of radiation sources cannot be curbed, training Radiation Protection Officers will improve the radiation safety standards within these companies and promote the safe use of the radiation sources. Therefore this project covers the fundamental elements required to train Radiation Protection Officers in Industrial Radiography. (author)

Radiation sterilization: an industrial process

International Nuclear Information System (INIS)

Ley, F.J.

1975-01-01

A new dimension has been added to the use of radiation in the medical field with the introduction of radiation as a sterilizing agent. Its use in diagnosis through radioactive tracers or X-rays and in therapy administered with the most sophisticated of electrical machines or radioisotope units, is familiar in the hospital world, being well established therein. In contrast, the application of radiation sterilization is in industry where the installation of large radiation sources is already commonplace in many countries. The beginnings in the early 1950's centered on the Van de Graaff machine and linear accelerators and the pioneering efforts of Ethicon Inc. here in the United States must be recognized. However, although sterilization with electron beams is still current practice in a number of plants, the use of gamma rays from cobalt-60 is preferred. The first steps in this direction were taken by the U.K.A.E.A. which, in common with similar organizations elsewhere, was attempting to exploit the tremendous potential for cobalt-60 production arising through the rapid construction of nuclear reactors. The first full-scale commercial gamma plant was commissioned in the U.K. in 1960. It reached a loading of 500,000 curies before its demolition after twelve years of operation. The process gained rapid acceptance within industry and approval by health authorities because it provided a ''cold'' sterilization method combining the property of lethal effect with penetration. Its immediate impact occurred in the introduction of disposable products making it possible, for example, to use heat-labile plastics and new packaging materials and package designs. Certainly, the technique has proved complementary to sterilization methods based on heat and to the use of chemical agents, in particular ethylene oxide gas

Development of a training programme for radiation protection officers in industrial irradiators

International Nuclear Information System (INIS)

Mumuni, I. I.

2014-01-01

The International Basic Safety Standards (BSS) for Protection against Ionizing Radiation and for the Safety of Radiation Sources establish the basic requirements for protection against the risks associated with exposure to ionizing radiation and for the safety of radiation sources that may deliver such exposure. One important aspect of the Safety Standard is education and training of all personnel involved in the activities of radiation and radioactive sources. According to the BSS a Radiation Protection Officer is an individual technically competent in radiation protection matters relevant for a given type of practice who is designated by the registrant or licensee to oversee the application of the requirements of the standards. By this assigned role, radiation protection officers for industrial irradiators should be adequately trained since these facilities involve very high dose rates during irradiation, such that a person accidentally exposed can receive a lethal dose within minutes or seconds and fatalities can occur. This training among others things will enable the radiation protection officers to understand practical application of the IAEA Safety Standard to industrial irradiator facilities, understand the requirements for safety assessments and emergency plans, be able to develop a radiation protection programme for irradiators, be familiar with the different types of industrial irradiators and their applications and understand the safety philosophy and design requirements for industrial irradiators.

Paulo César de Sousa Batista

2016-06-01

Full Text Available ABSTRACT This research analyses how the interaction between strategy capabilities, strategy types, strategy formulation quality and implementation capability affect organizational performance in Brazilian textiles companies. This article proposes and tests a conceptual framework, using a structural equation modeling of a set of 211 valid questionnaires on Brazilian textiles firms. The results support links between focus strategy and marketing capabilities, and between cost leadership strategy and management capabilities. However, the relationship between technologic capabilities and differentiation strategy was not statistically significant. The existence of an inter-relationship between generic strategies of focus, cost leadership and differentiation indicates the use of combined strategies. Concerning the firms' financial performance, the results show that management capability and market performance have a statistically significant relationship with financial performance.

Full Text Available The manufacturing industry's loss in participation, phenomena called “deindustrialization”, has been observed for the Brazilian economy for a while and seems to have intensified from mid-2000s. However, the literature has not developed a consistent or integrated analysis of this process. We have used a detailed simulation model to identify how macroeconomic factors (such as exchange rate, labor costs, and household consumption have contributed to manufacturing dynamics. Our results indicate that the macroeconomic scenario explains a large portion of the manufacturing industry's participation loss. The rise in households consumption and investment, important factors in this period, were responsible for dampening of the pressures coming from the currency appreciation and the workforce costs, benefiting some industrial sectors, but not avoiding the manufacturings participation loss.

Among the contributions of this work are to review the literature on the subject, identified the influence of variables of CSR in BI and RC and the differences in consumer perception for each of the brands studied, as well recommendations for future studies.

Radiation in industrial processes;Applications reviewed at Warsaw Conference

1959-10-15

The uses of ionizing radiation can be divided into two broad categories. First, it can be used as a tool of investigation, measurement and testing, and secondly, it can be a direct agent in inducing chemical processes. For example, radiation can help in the detecting and locating of malignant tumours, and it can be employed also for the destruction of those tumours. Again, it can reveal intricate processes of plant growth and, at the same time, can initiate certain processes which result in the growth of new varieties of plants. Similarly in industry, radiation is both a tool of detection, testing and measurement and an active agent for the initiation of useful chemical reactions. The initiation of chemical reactions usually requires larger and more powerful sources of radiation. Such radiation can be provided by substances like cobalt 60 and caesium 137 or by machines which accelerate nuclear particles to very high energies. Of the particle-accelerating machines, the most useful in this field are those which accelerate electrons to energies considerably higher than those possessed by the electrons (beta particles) emitted by radioactive substances. These high-energy radiations produce interesting reactions both in organic life and in materials for industry. Several of the papers presented at the Warsaw conference were devoted to the application of ionizing radiation to polymerization and other useful reactions in the manufacture and treatment of plastics. The polymerization of the ethylene series of hydro-carbons was discussed from various angles and the technical characteristics and requirements were described. It was pointed out by some experts that the cross-linking effect of radiation resulted in a superior product, opening the way to new applications of polyethylene. Irradiated polyethylene film has been sold for several years, and electrical wire has been made with irradiated polyethylene as the insulating jacket. Other reactions discussed included the cross

Eupatorieae are one of the largest tribes in Asteraceae with 14 of 19 recognized subtribes occurring in Brazil. We constructed the largest phylogeny of Brazilian Eupatorieae to date that sampled the nrITS and ETS, chloroplast ndhI and ndhF genes, and the ndhI-ndhG intergenic spacer for 183 species representing 77 of the 85 Brazilian genera of the tribe. Maximum likelihood and Bayesian phylogenetic analyses showed that these species are not collectively monophyletic, so their distribution reflects multiple introductions into Brazil. A novel clade was found that includes 75% of the genera endemic to Brazil (Cerrado-Atlantic Forest Eupatorieae, "CAFE" clade). This radiation of at least 247 species concentrated in the Cerrado and Atlantic Forest biomes of central eastern Brazil is <7 my old and exhibits several ecologically diverse life forms. Eight subtribes of Brazilian Eupatorieae (Ageratinae, Alomiinae, Ayapaninae, Critoniinae, Disynaphiinae, Eupatoriinae, Gyptidinae and Hebecliniinae) and 16 genera (Ageratum, Agrianthus, Austroeupatorium, Bejaranoa, Chromolaena, Critonia, Disynaphia, Grazielia, Hatschbachiella, Heterocondylus, Koanophyllon, Lasiolaena, Neocabreria, Praxelis, Stylotrichium, and Symphyopappus) were found to be polyphyletic. We attribute incongruities between the molecular phylogenetic results and the current classification of the tribe mostly to convergent evolution of morphological characters traditionally used in the classification of the tribe. We used these phylogenetic results to suggest changes to the classification of some subtribes and genera of Eupatorieae that occur in Brazil. Copyright © 2015 Elsevier Inc. All rights reserved.

Pujol, L.; Lara-Calleja, S.; Suarez-Navarro, M. J.; Gonzalez-Gonzalez, J. A.

2009-01-01

The industry of the iron and the steel in one of the most important sectors in Spain for its economic development. the recycling of metallic materials as well as the import of metallic scrap is very significant. Several reports on accidental dispersion or smelting of radioactive sources in metal recycling industries confirm the possibility that radioactive material might be mixed with scrap. In consequence, this type of accident shows the necessity of a rigorous and specific radiation control of the sector. The control of these materials with radioactive content can be carried out with radiation portal monitors installed at the entrance of these industries. The detection of radioactive materials presents special features as the continuous background acquisition or the minimisation of the relatively large number of innocent/nuisance detections. In the present work, we study a radiation portal monitor, the FHT-1388-T Thermo-Eberline. This is one of the usual radiation portal systems installed at the entrance of the metal recycling industry. Se study the characteristics and parameters of this portal monitor to optimise its use. furthermore, we propose some rapid tests for radiation portal systems in metal recycling industry.

Radiation processing in the plastics industry

International Nuclear Information System (INIS)

Saunders, C.B.

1988-01-01

The interaction of ionizing radiation with organic substrates to produce useful physical and chemical changes is the basis of the radiation processing industry for plastics. Electron beam (EB) accelerators dominate the industry; however, there are a few small applications that use gamma radiation. The five general product categories that account for over 95% of the worldwide EB capacity used for plastics production are the following: wire and cable insulation; heat-shrinkable film, tubes and pipes; radiation-curable coatings; rubber products; and polyolefin foam. A total of 6.1% of the yearly production of these products in the United States is EB treated. The United States accounts for 59% of the total worldwide EB capacity of 20.5 MW (1984), followed by Europe (16%) and Japan (15%). There are 469 to 479 individual EB units worldwide used for the production of plastics and rubber. The average annual rate of growth (AARG) for the EB processing of plastics in Japan, from 1977 to 1987, was 13.3%. The AARG for Japan has decreased from 20% for 1977 to 198, to 6.4% for 1984 to 1987. Radiation cross-linking, of power cable insulation (cable rating ≥75 kV), thick polyolefin and rubber sheet (≥15 mm), and thick-walled tubing is one fo the potential applications for a 5- to 10-MeV EB system. Other products such as coatings, films and wire insulation may be economically EB-treated using a 5 to 10 MeV accelerator, if several layers of the product could be irradiated simultaneously. Two general product categories that require more study to determine the potential of high-energy EB processing are moulded plastics and composite materials. 32 refs

Radiation processing has long been known as commercially viable technology that can be beneficially used to enhance the characteristics of many materials. Several gamma irradiators and electron beam accelerators are operating worldwide which are utilized for various established industrial applications. These could be used for the following processes: a) radiation crosslinking e.g. crosslinking of wires and cables, heat shrinkable film and tube productions, manufacture of plastic bags and tubings for medical products, pre-curing of automobile tire components, curing of polymeric coatings, etc. b) radiation degradation e.g. Scrap Teflon (Polytetraflouroethylene) to form powders, disinfestations and pasteurization of agricultural products, sterilization of medical products, etc.; and c) radiation grafting e.g. grafted non-woven fabrics for metal adsorbent. Emerging applications for radiation processing include grafted membranes for fuel cell, electrodes, cell sheet for tissue engineering, nanoparticle production, polymer composite synthesis, and fibrous catalyst for biodiesel production. Current researches at the Philippine Nuclear Research Institute consist of crosslinking of natural and synthetic polymers for medical application e.g. wound dressing, hemostats, and bioimplants for vesicouretal reflux (VUR); grafting of natural and synthetic fabrics for metal adsorbents; and radiation degradation of carrageenan as plant growth promoter.

Synchrotron radiation and industrial research

International Nuclear Information System (INIS)

Townsend, R.P.

1995-01-01

Fundamental studies on the properties of many different materials are of prime importance to most industrial concerns. For Unilever, solids (crystalline and amorphous), soft solids and complex fluids are the materials of primary interest. Synchrotron radiation has proved of great value for the analysis of a variety of such materials, because the intense and highly collimated radiation source has enabled us to obtain structural information rapidly as well as in time-resolved mode. In this paper are outlined the types of materials problems faced, and how we use different techniques to elucidate structure (both short and long range order) in zeolites, amorphous solids, as well as in biomaterials such as skin and hair containing lipid phases. Both equilibrium and time-resolved studies are described. (orig.)

Mohamad Yusof Mohamad Ali

1987-01-01

There is a substantial increase in the use of ionizing radiation in industry throughout the country especially in the last five years or so. With this growth in the number of users and activity of sources used, and together with the introduction of the new Atomic Energy Licensing Act (AELA) in 1984, the question of radiation safety and protection of workers and members of the public in general, can no longer be taken lightly. It has to be dealt with effectively. In this paper, a general discussion and clarification on certain practical aspects of radiation protection as recommended by the International Atomic Energy Agency (IAEA) is presented. Amongst the topics chosen are those on area monitoring, personnel monitoring, leak testing of sealed sources and training of personnel. Also presented in the paper is a brief discussion about UTN's experience in giving out radiation protection services to various agencies throughout the country. (author)

The Isotope Division of BARC is equipped with a 2-MeV electron beam (EB) accelerator and a 70,000 Ci Cobalt-60 source: these are mainly utilized to develop technologies of interest to our industries and needs. These include development of polyethylene 'O' rings having dimensional stability above the melting point, radiation degradation of PTFE and enhancement of colour in diamonds. The viscose rayon industry is an important industry in India. This industry faces stiff regulations from environmental pollution control agencies primarily due to the emission of toxic sulphur containing gases, and is in search of ways to reduce the pollution levels associated with the process. The irradiation of cellulose with ionizing radiation results in cellulose activation and reduction in the degree of polymerization (DP). There is a keen interest in utilizing radiation technology in viscose rayon production. We have utilized the 2-MeV electron beam accelerator for reducing the degree of polymerization (DP) of paper pulp. Laboratory scale tests have been carried out to standardize the conditions for processing of pulp having desired degree of polymerization. Our studies show that the use of irradiated pulp can significantly reduce the consumption of CS 2 and be beneficial in reducing pollution associated with the process. An electron-beam irradiation based process has been developed to convert the PTFE waste into a low molecular weight (1x10 4 -1x10 5 ) PTFE powder that can be easily processed into a fine micropowder having industrial demand. Even carbon or metal filled PTFE has been recycled using this process. The conventional method of crosslinking linear polymers by thermo-clinical method leads to the formation of homogeneously crosslinked materials which are extremely slow for industrial applications. Electron beam irradiation has been used to create inhomogeneous crosslinking of a temperature-sensitive polymer- poly(vinyl methyl ether)(PVME) so as to produce a fast response

Strategic Management at Mormaii - the Brazilian Surf Industry Leader

Directory of Open Access Journals (Sweden)

Marcos Abilio Bosquetti

2017-01-01

Full Text Available The sport of surfing has been growing rapidly in popularity worldwide and Brazil is among the countries with the largest surfing population, behind the United States and Australia, however, multinational surf companies are rushing in emerging markets like Brazil to find new opportunities for growth. This paper intends to provide insights on how local companies in these markets can overcome and even take advantage of differences with global competitors by re-thinking their core competencies and business models. Therefore, empirical research applying qualitative case study methodology was developed to investigate the role of strategy in the surf industry - a fairly unexplored research topic. Semi-structured in-depth interviews with the founder and CEO and the executive directors at the Brazilian surf industry leader - Mormaii, were conducted to understand how the 4-decade local company found its way to success. Although the theories: RBV, Core Competencies, and Dynamic Capabilities complement each other and help to explain firms’ performance and strategic choices, in empirical studies strategy has been analyzed only by one or another theory. Therefore, the simultaneous use of these three theories intended to fill this gap in the literature and bring more consistency to the discussion of this case study. As a result, this empirical study illustrates the RBV perspective, which stems from the principle that the source of firms’ competitive advantage lies in their internal resources and capabilities, rather than simply evaluating environmental opportunities and threats in conducting business. It also highlights the role that core competence and dynamic capabilities play in the company’s virtuous circle of sustainable growth and provides practitioners clues for re-thinking their strategies.

Nuclear and radiation applications in industry: Tools for innovation

International Nuclear Information System (INIS)

Machi, S.; Iyer, R.

1994-01-01

Applications of nuclear and radiation technologies have been contributing to industrial efficiency, energy conservation, and environmental protection for many years. Some of these are: Manufacturing industries: Radiation processing technologies are playing increasing roles during manufacturing of such everyday products as wire and cable, automobile tires, plastic films and sheets, and surface materials. Production processes: Other techniques employing radioisotope gauges are indispensable for on-line thickness measurements during paper, plastic, and steel plate production. Processing and quality checks are made using nucleonic control systems that are common features of industrial production lines. Sterilization of medical products using electron beam accelerators or cobalt-60 radiation is better than the conventional methods. Industrial safety and product quality: Non-destructive examination or testing using gamma- or X-ray radiography is widely used for checking welds, casting, machinery, and ceramics to ensure quality and safety. Additionally, radiotracer techniques are unique tools for the optimization of chemical processes in reactors, leakage detection, and wear and corrosion studies, for example. Environmental protection: An innovative technology using electron beams to simultaneously remove sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) has been under development. The electron beam technology is very cost competitive and its byproduct can be used as agricultural fertilizer

The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of β-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of α and β-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The β-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of β-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 μg 100 g -1 , and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 μg 100 g -1 , and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control. (author)

2017-01-01

Brazil has approximately 2000 radiative facilities that use radiation sources in their processes and are controlled by The Brazilian Nuclear Energy Commission - CNEN through standards, authorizations and inspections. These radioactive materials, whether in the form of waste or radioactive source, used in medical, industrial, research, etc. are sometimes discarded and found in inappropriate places, such as garbage dumps, industrial waste, streets, squares, etc. found by urban cleaning professionals without the proper knowledge of them. The work presents the radiation protection actions required for the safe collection of radioactive material to be performed by these professionals. According to the type of radioactive material the main actions of radiation protection are, among others: recognition of a radioactive material; correct use of personal protective equipment to contain possible radiation contamination; implementation of an area control etc. In order for the actions of recognition and collection of discarded radioactive material to be effective, there is a need to implement a training program in radiation protection for urban cleaning professionals

This paper describes the goods and services supply oil segment, as different than the oil companies segment itself. It points to the transformations in the goods and services supply segment from the 1980s until now. At that time with low international oil prices, the oil companies induced the goods and services firms to assume a major role in development of technology. Inside the country here, the goods and services segment had high local content performance but it was associated to low technology intensity or to branches of large multinational firms installed in the Brazilian market. The paper points the French approaching on this same oil segment and its applicability to the Brazilian case, giving one example of financial R and D resources for supporting such a target. Otherwise than in France some specific obstacles can be found here in that development purpose. As alternative some others scenarios were finally explored in the paper for further suggestions for institutional approaching in this Brazilian industrial oil segment. (author)

Radiation safety training for industrial irradiators: What are we trying to accomplish?

International Nuclear Information System (INIS)

Smith, M.A.

1998-01-01

Radiation safety training at an industrial irradiator facility takes a different approach than the traditional methods and topics used at other facilities. Where the more routine industrial radiation users focus on standard training topics of contamination control, area surveys, and the traditional dogma of time, distance, and shielding, radiation safety in an industrial irradiation facility must be centered on preventing accidents. Because the primary methods for accomplishing that goal are engineering approaches such as safety system interlocks, training provided to facility personnel should address system operation and emergency actions. This presents challenges in delivering radiation safety training to an audience of varied educational and technical background where little to no commercially available training material specific to this type of operation exists

Present status of industrial utilization of radiation exposure

Machi, Sueo

1987-01-01

Radioisotopes, such as Co-60 and Cs-137, and accelerators for electrically generating radiations are widely used as radiation sources for industrial radiation exposure applications. It is estimated that about 100 electron accelerators are in use in Japan as of 1985 in the industrial and R and D fields while about 300 - 400 accelerators and more than 130 Co-60 irradiation systems have been installed over the world. In the field of materials development, accelerators are currently utilized for production of cross-linked, high-temperature resistant cable cladding, production of heat-shrinkable polymer materials, pre-crosslinking of rubber sheet for tier, production of expanded polyethylene, graft copolymerization for producing diaphragms for battery, electron-beam surface coating, and lithography for semiconductor manufacturing. In the field of environmental protection, accelerators are employed for removal of sulfur dioxide and nitrogen oxides from gas emission, sterilization and composting of sludge, and electron treatment of water. Radiations are also used for sterilization of medical instruments. In addition, high-energy ion beam irradiation has already come into practical use in the field of semiconductor manufacturing and metallic surface treatment. (Nogami, K.)

Radiation ionization is an underestimated industrial technique

International Nuclear Information System (INIS)

Anon.

1999-01-01

Industrial radiation ionization requires electron beams coming from an accelerator or gamma radiation from a radioactive source (Co 60 ). The energy deposed in the irradiated material modifies its chemical bounds or kills micro-organisms. This process is used in medical material sterilization, in disinfestation of stored and packaged food products, in the production of plastic, in the coloring of glass, in the hardening of electronic components and in the modification of the properties of semi-conductors. For 40 years radiation ionization has been investigated, UNO (United Nations Organization) and WHO (World Health Organisation) recommend it for food processing. With a growing rate of 15% per year for the last 15 years, radiation ionization is now widely used. More than 170 gamma irradiation facilities are operating throughout the world. (A.C.)

Risks derived from the industrial uses of ionizing radiation

Energy Technology Data Exchange (ETDEWEB)

Alonso, A

1981-01-01

The industrial uses of ionizing radiation are clasified according to its importance in the surveillance and control of industrial processes, the possibility of modifying properties of materials under irradiation and the liberation and transformation of nuclear and desintegration energy into other useful forms. Within that framework, the industrial uses of radiation in Spain are presented together with an indication of the amount and classification of responsible operating personal. The basic concepts of risk and benefit are analyzed to show that the public perception of nuclear risk is greater that the real one. To bring both together, it is important to show a good operating experience and to develop a complete and precise set of rules and regulations. The situation in Spain on this later concept is presented in some detail.

Ethanol has recently been of great interest worldwide because it is a viable economic alternative to petroleum products and it is a renewable source of energy that mitigates the emission of greenhouse gases. Brazilian bioethanol from sugarcane is the most successful case at the world level because of its low cost and low level of greenhouse gas emissions. Brazil's success with sugarcane cannot be understood as based solely on a natural comparative advantage, but as a result of efforts that culminated in a positive trajectory of technological learning, relying mostly on incremental innovations. The purpose of this article is to analyze the key aspects of the innovation system built around the Brazilian sugarcane industry. It is based on the national innovation systems approach according to which innovation results from the interaction of different institutional actors. Institutional arrangements are analyzed as the basis for the innovative process, in particular R and D and the innovation policies and strategies of the main players in the sugarcane sector, including sugar and ethanol mills, industrial goods suppliers, public and private research institutions, and governmental agencies. - Research Highlights: → The Brazilian success in bioethanol is due to the sugarcane innovation system. → Private funds for R and D became central after IAA closure. → Nowadays Brazilian innovation system is transforming to keep its leadership. → Public funds for research in the second generation bioethanol.

Pequi: a Brazilian fruit with potential uses for the fat industry

Directory of Open Access Journals (Sweden)

Guedes Andréa Madalena Maciel

2017-09-01

Full Text Available Pequi is a native fruit from Brazil, found in the Amazon, Caatinga, Cerrado and Atlantic Rain Forest regions. It is one of the main plants with great potential for sustainable use in Central Brazil. Among 16 species comprising Caryocar genus, three are highlighted: C. brasiliense, C. villosum, and C. coriaceum, of economic importance for families in small communities of Brazilian Cerrado. They are generally organized in cooperatives and use the leaves for preparing medicinal extracts, and the fruits for culinary purposes. When the sale of fresh fruits is reduced, they produce and commercialize fruit preserves, and liqueur products, as well as extract the oil. Harvesting of mature fruits after falling from the tree while keeping some fruits at the plant is the best way for its sustainable production. The internal mesocarp contains from 36 to 66% dry weight of oil having traditional culinary, medicinal and cosmetic uses. This oil has 60% of oleic acid and 35% palmitic acid, thus suitable for industrial fat hardstocks. The presence of the triacylglycerols POO and POP makes the oil of interest for cosmetic and food industries. Both pulp and kernel oils have been studied for their health effects. By physical, enzymatic or chemical modification, the oil has shown potential uses as cocoa butter substitute and zero trans fat product.

Full text: A vast variety of nuclear techniques is available for industrial, environmental, medical and research applications. Sealed or open radioisotope sources are applied as radiotracer in the system, in nucleonic gauges, in non destructive testing and in nuclear analytical techniques. Beside of isotopes X-ray tubes and accelerators operated in e-/X mode as a source of radiation are applied as well. These methods are used for process and material control, non-destructive evaluation of wells, castings and assembled machinery help to make industrial processes safer and more cost effective. For natural resource exploration radiotracers (RTT), sealed sources and nucleonic gauges (NCS) are used in the oil industry, in mineral processing and waste water treatment plants. Radioisotopes make important contributions in several sectors of economic significance including medicine industry, agriculture, structural safety and research. They are generally produced in research reactors or cyclotrons. More than 150 different radioisotopes in different forms are in use for various applications. Non-destructive testing (NDT) is essential for quality assurance of various products in diverse industries and construction projects apart from well established NDT protocols for industrial components, machinery and chemical pipelines, new techniques and applications, such as digital radiography for ecological safety, online inspection of concrete structures and pipe corrosion, are being developed. The new applications concern cargo inspection where Co 60 or e-/X sources are used. Radioisotopes are applied as radiotracers in industry and environment. Oil fields and refineries, chemical and metallurgical industries and wastewater purification installations are the end users benefiting from radioisotope techniques. Radioisotope techniques (radiotracers, gamma scanning, tomography and single particle tracking) are extensively used to identify and quantify multiphase reactors (phase hold

The Western Australian mineral sands industry: radiation protection

International Nuclear Information System (INIS)

1989-01-01

The need for radiation protection in the mineral sand industry derives from the production and handling of monazite, a rare earth phosphate which contains 6 to 7% thorium. The purpose of this booklet is to outline the complex and detailed radiation protection surveillance program already in place. It is estimated that the quality of radiation protection has improved in recent years with respect to reporting and recording-keeping dust sampling procedures, analytical determination, training and instruction, as well as to a corporate commitment to implement dust reduction strategies. 15 figs., 2 tabs., ills

Evaluation of a label dosimeter to be used for Brazilian irradiated fresh fruits

International Nuclear Information System (INIS)

Del Mastro, N.L.

2001-01-01

The main difficulties for Brazilian fruit exports are phytosanitary barriers. Irradiation can be used as a single treatment, part of a multiple treatment or combined with other mitigation measures as a component of a systems approach which would be a treatment for plant pests of quarantine significance. For any kind of industrial irradiation, determining the absorbed doses involves a dosimetry system that covers the absorbed dose range of interest and shall be calibrated before use. Frequently, however, it is useful to also have a radiation sensitive indicator to visually determine whether or not a product has been irradiated. STERIN labels were designed as threshold indicators, where a visual message changes after exposure at or above the threshold indication dose (e.g. 125 Gy, 300 Gy). The aim of this work was to evaluate STERIN label indicators to be used for Brazilian irradiated fresh fruits. (author)

Radiation and radioactive substances are natural and permanent features of the environment; additionally the use of human made radiation is widespread. Sources of radiation are essential to modern health care, disposable medical supplies sterilized by intense radiation have been central to combating disease, radiology is a vital diagnostic tool and radiotherapy is commonly part of the treatment of malignancies. Nuclear techniques are in growing use in industry, agriculture, medicine and many fields of research, benefiting hundreds of millions of people and giving employment to millions of people in the related occupations, Irradiation is used around the world to preserve and reduce wastage and sterilization techniques have been used to eradicate disease carrying insects and pests. Industrial radiography is in routine use, for example to examine welds and detect cracks and help prevent the failure of engineered structures. It is also known that exposure to ionizing radiation can result to injuries that manifest themselves in the individual and his descendants. It is therefore imperative that the use of radiation sources be accompanied with the methods necessary for the prevention of the harmful effects of the radiation. These methods are referred to as control measures. Control measures that have been applied in establishments can be classified into physical control measures and administrative control measures. Physical control measures involve the technical aspects while administrative control measures augment physical measures. The guidelines and recommendations for the safe use of radiation and radioactive materials are provided through legislative and regulatory controls

The use of radioisotopes and radiation is expanding in the fields of industries and medicine with a high potentiality of the application to environmental protection. The technology transfer on the use of isotopes and radiation is progressing in the framework of international cooperation. But the industry has maintained wait and see attitude on the commercialization of food irradiation. Such present features were the highlight in the 19th Japan Conference on Radiation and Radioisotopes held on November 14-16. 72 papers from 19 countries were presented and discussed in 13 sessions. The progress of accelerator technology has contributed to the expansion of radiation processing market. The importance of the application of isotopes and radiation to environmental protection has been gradually acknowledged, and the electron beam treatment of flue gas for acid rain abatement and the elimination of chlorinated ethylene from drinking water were discussed. Drastic change has not been seen in the climate of food irradiation, however there are several positive indicators which support the prediction of slow but steady progress in the commercialization of the process and the trade of irradiated foods.

Federal radiation protection regulations: An industry viewpoint

International Nuclear Information System (INIS)

Harward, E.D.

1987-01-01

Regulations and standards to protect the public and workers from ionizing radiation have been in transition for a number of years, although most of the basic limits in use have remained essentially unchanged over the past 25 years or so. Legislation, political changes, new scientific data, advances in scientific concepts, and finally, public perception and resulting pressures have all been factors in the modifications that have been implemented or considered for radiation protection regulations in recent years. During this period, radiation exposures to both the public and the work force have been reduced through program management and improved technology. Based on activities of the AIF Subcommittee on Radiation Protection, this paper reviews pertinent NRC and EPA regulations, standards and guidance as well as NCRP recommendations and provide some analyses of these in terms of their potential effect on nuclear industry operations. Comments include suggestions where minor changes in Federal agency approaches to radiation regulation might be made for the public benefit

The author uses the Michael Porter framework, (from the University of Harvard), about the 'Competitive Advantage of Nations', as a theoretical instrument to analyze the Brazilian oil industry. The document studies, specifically, the related and supporting industries, one of the four determinants that, according to the author, promote the creation of national competitive advantages; the others are: the factors conditions; the demand conditions; and the firm strategy, structure and rivalry. The study aims at building a general view of competitiveness for the so called supply industries to the oil sector, which have a fundamental role in this model. Although Brazil has developed, with the leadership of PETROBRAS, a complex industrial system, this structure of related and supporting industries will have to face new challenges, having to improve efficiency, reduce costs and redefine its global strategies.

2008-01-01

Full text: After many years in the economic doldrums the world's uranium industry is undergoing a renaissance. The recent rapid price increase for the product and the anticipated market shortfalls in supply of yellowcake have are responsible for this. There is now a rush of new activity: abandoned mines from a previous era are being re-examined for their potential to be re-opened; planning for exploitation of known but undeveloped uranium deposits is proceeding at a rapid pace in many countries new to uranium mining; and finally worldwide exploration activity for uranium is expanding at a great rate with more than 400 companies now claiming to be involved in the uranium mining market. All of there activities have significant implications the radiation protection profession. At every stage of the uranium production cycle, from exploration to mining and processing through to remediation there are requirements for proper radiation protection procedures and regulation. The long period of reduced activity in uranium mining has meant that few young people have been joining the industry over the past 20 years. There is now a shortage of trained and experienced radiation protection professionals associated with the mining industry that cannot be overcome overnight. The paper discusses the development of this situation and the various strategies that are being put in place around the world to improve the situation. In particular the International Atomic Energy Agency has been working with radiation protection authorities and uranium mining industry representatives from around the world to address the issue. The latest developments in this project will be described and the future plans described. (author)

This paper estimates a structural model of the Brazilian carbonated soft drink industry to test the claim that the observed low prices of low-end entrants owe to marginal cost advantages over the large, established brands, allegedly stemming chiefly from tax evasion. Such entrants, numbering in the hundreds, are typically small-scale operations, with limited geographic reach and no advertising. In addition to the low-cost hypothesis, advocated by the incumbent duopolists, the model allows for...

Evolution of the radiation processing industry

Cleland, Marshall R.

Early investigations of the effects of treating materials with ionizing radiations began in 1894 with the irradiation of gases at atmospheric pressure using cathode rays from a Crookes gas-discharge tube, in 1895 with the discovery of X-rays emitted from a Crookes tube, and in 1896 with the discovery of radioactivity in uranium. In 1897, small electrically charged particles were detected and identified in the gas discharges inside Crookes tubes. These particles were then named electrons. During the next three decades, it was found that these novel forms of energy could produce ions to initiate chemical reactions in some gases and liquids. By 1921, it had also been shown that insects, parasites and bacteria could be killed by treatment with ionizing radiation. In 1925, a high-vacuum tube with a thermionic cathode and a thin metallic anode was developed to produce electron beams in air by using accelerating potentials up to 250 kilovolts. That unique apparatus was the precursor of the many types of electron accelerators that have been developed since then for a variety of industrial applications. In 1929, the vulcanization of natural rubber without using any chemical additives was achieved by irradiation with electrons from a 250 kilovolt accelerator. In 1939, several liquid monomers were polymerized by treatment with gamma rays from radioactive nuclides. These early results were not exploited before the end of World War II because intense sources of ionizing radiation were not available then. Shortly after that war, there was increased interest in developing the peaceful uses of atomic energy, which included the chemical and biological effects of radiation exposures. Many uses that have been developed since then are described briefly in this paper. These industrial applications are now producing billions of US dollars in revenue every year.

Public relations and the radiation processing industry

Science.gov (United States)

Coates, T. Donna

The world's uneasiness and mistrust regarding anything nuclear has heightened in recent years due to events such as Chernobyl and Three Mile Island. Opinion polls and attitude surveys document the public's growing concern about issues such as the depletion of the ozone layer, the resulting greenhouse effect and exposure of our planet to cosmic radiation. Ultimately, such research reveals an underlying fear regarding the unseen impacts of modern technology on the environment and on human health. These concerns have obvious implications for the radiation processing industry, whose technology is nuclear based and not easily understood by the public. We have already seen organized nuclear opponents mobilize public anxiety, fear and misunderstanding in order to oppose the installation of radiation processing facilities and applications such as food irradiation. These opponents will no doubt try to strengthen resistance to our technology in the future. Opponents will attempt to convince the public that the risks to public and personal health and safety outweigh the benefits of our technology. We in the industry must head off any tendency for the public to see us as the "enemy". Our challenge is to counter public uneasiness and misunderstanding by effectively communicating the human benefits of our technology. Clearly it is a challenge we cannot afford to ignore.

Full Text Available Innovation networks have been identified in the literature as a way to complement firms’ innovative capabilities through collaboration with other partners. To provide empirical evidence for this assertion, this paper investigates the contribution of partners established in innovation networks for innovative performance of firms in the Brazilian electricalelectronics industry. For this purpose, we carried out an exploratory and descriptive survey among 185 companies. The data were analyzed using structural equation modeling (SEM. As the main findings, we observed that the establishment of collaborative relationships with customers, competitors and universities/research institutions can contribute to organizational and process innovation. However, despite obtaining some significant results concerning the contribution of different partners in the network, electrical-electronics industry companies also attach great importance to internal activities to develop their innovations.

The paper presents the Brazilian Nuclear Energy Programme, its development, the organizations and the distribution of responsibilities involved in its execution at the present time. The nuclear power policy is established at the Presidency of the Republic and is planned, executed and controlled through the Ministry of Mines and Energy. Directly subject to the Ministry is the Brazilian Nuclear Energy Commission (CNEN), which has regulatory, standardization, licensing, planning and surveillance functions. The nuclear fundamental research and manpower formation are also under CNEN responsibility. Also subject to the Ministry are two companies responsible for the execution of the Programme: the Centrais Eletricas Brasileiras S.A. - Eletrobras, which advises on the granting of permits for the construction and operation of nuclear power plants, and the Empresas Nucleares Brasileiras S.A. - Nuclebras, which holds the monopoly of the nuclear fuel cycle in the country, designs and builds nuclear power plants and provides assistance to the electric utilities and promotes the participation of Brazilian industry. Besides describing the new distribution of regulatory functions given by law to CNEN, the paper gives special emphasis to the large industrial complex in the process of being established through the setting-up of the many Nuclebras subsidiaries in joint venture with German firms under the Industrial Co-operation Agreement Between Brazil and the Federal Republic of Germany in the Field of the Peaceful Uses of Nuclear Energy. The programmes for these subsidiaries are presented and their participation in the Brazilian Nuclear Energy Programme is discussed. The technology transfer aspects of the industrial activities are also discussed. (author)

The Brazilian nuclear industries - INB - in the field of the rare earth

The Brazilian Nuclear Industries - INB is responsible for the execution of part of the cycle of uranium as nuclear reactor fuel for alternative energy generation. Soon INB shall increase the participation in this cycle, through the implantation of the line of powder and pastille. INB is also the successor of the monazite processing industries. The last one was NUCLEMON that was incorporated by INB. The connection of INB with this area is due to the presence of the strategic elements uranium and thorium in the monazite. The know-how was and continues to be developed by a chemical team of the National Commission of Nuclear Energy (CNEN) with the collaboration of the technical team of INB. The ever wider applications of the individual Rare Earth in the most different fields of the electrical, electronics, communication, optical, metallurgical, catalysis and other industries, as well as INB incessant inquire for the economical workability, brought INB to appraise the position regarding to the industrial production of the Rare Earth. The choice is bringing to the separation and commercialization of the individual elements and/or in groups containing a reduced number of Rare Earth, instead of the production and commercialization of the mixture of monazitic Rare Earth. This paper illustrates through quantitative information some aspects regarding to reserves, mining and physical separations of the monazite, as well as projections about INB resuming its industrial activities with insertion of technical improvements in both, the chemical treatment of the monazite and the Rare Earth separation. In this field, there will be presented in this paper the qualitative and quantitative results recently reached in a large dimension pilot plant. These results add to the technical conquest reached in the late years by the foregoers of INB, and that will be also presented. The paper contains also some appreciations regarding to the perspectives of INB's ingression in the field of

A modern approach often used in international literature says that the government has the role to create favorable conditions for improving energy efficiency in industry, either through policies, programs or actions. This article's main objective is to describe the main programs for promoting energy efficiency in industry in Brazil and in other countries, for later to propose a new approach for the management and development of energy efficiency programs for the Brazilian industry. The creation of an executive agency, connected to the MME and with strong ties to ELETROBRAS and PETROBRAS, could manage effectively the enormous resources that are needed to mobilize the energy efficiency programs as real alternatives to programs for additional expansion in energy supply. The creation of energy assessment centers, along with an energy efficiency program for energy-intensive industry, would help in promoting energy efficiency in industry. These actions would likely bounce in other industries, and would assist in achieving optimal management standards in the energy industry, consistent with ISO 9000 and ISO 14000, used in countries like the USA and Sweden.

For selection of radiation processes in industry the processes usually are analyzing by technological and social effects, power-insensitivity, common efficiency. Technological effect is generally conditioned with uniqueness of radiation technologies which allow to obtain new material or certain one but with new properties. Social effect first of all concerns with influence of radiation technologies on consumer's psychology. Implementation of equipment for radiation technological process for both the new material production and natural materials radiation treatment is related with decision of three tasks: 1) Choice of radiation source; 2). Creation of special equipment for radiation and untraditional stages of the process; 3) Selection of radiation and other conditions ensuring of achievement of optimal technological and economical indexes

The objective of this work is to evaluate current emissions of GHGs within the Brazilian oil and gas industry, specifically the fugitive emissions arising from exploration and production. Besides, projects for mitigating these emissions and opportunities for the national industry are investigated. Results show that N{sub 2}O contributes little to fugitive emissions from the oil and gas industry, principally from gas sector. NMVOC emissions are significant, principally from the oil sector. In relation to CO{sub 2} and CH{sub 4} emissions, the oil sector emits more CO{sub 2} while the gas sector contributes more to CH{sub 4} emissions. In both sectors flaring is the activity that emits most CO{sub 2}. In relation to CH{sub 4} the principal contribution to emissions are from exploration and production onshore, although offshore activities as a whole play a greater part in the national industry. The results make it clear that the use of gas from flaring activity is a great opportunity for emission mitigation projects. From a business point of view, methane emissions could mean lost opportunities in selling natural gas. The Kyoto Protocol mechanisms, as the Clean Development Mechanism and Joint Implementation actions, provide the opportunity to stimulate investments in projects for reducing flaring and venting of associated gas.

This paper outlines fundamental knowledge, health risks, and protection related to radiation in order to carry out appropriate industrial health management to reduce great public anxiety caused by the Fukushima Daiichi Nuclear Power Plant accident developed by the Tohoku earthquake and tsunami of March 11, 2011. Radiation generally causes damage to DNA such as generation of reactive oxygen species in cells, which are also created by exposures of various kinds of physical and chemical factors. This suggests that as well as applying 5 basic measures for industrial health management in the work place, common public health measures and disease prevention, such as keeping good sanitary conditions, healthy lifestyles, home discipline, social supports, efficient health education, etc. are important for us to prevent radiation-related cancer manifestation. Improvement of early detection and treatment for cancer is also important to eliminate the public anxiety. (A.O.)

There are many differences between industrial CT and industrial radiography, such as imaging principle, inspection time, radiation dose and the requirements for operators etc. The national standards for radiation protection of industrial detection are not applicable to the requirements of protection and safety for γ-ray industrial CT to some extent now. In order to standardize the production and use for γ-ray industrial CT, protect the safety of operators and the public, and to promote the popularization and application of γ-ray industrial CT, it is significant to establish the national standards for radiation protection of γ-ray industrial CT as soon as possible. The purpose of this paper is to introduce the contents of this standard, and specify some important terms. Then there is a brief discussion on the existing problems during establishing such standards. At last, the paper summarize the practice of the standards passed over the past one year, which provides practicable experience for the further implementation. (authors)

Determination of possible radiation hazards associated with tin mining industry in West Malaysia

International Nuclear Information System (INIS)

Hu, S.J.

1979-04-01

A study was made in Malaysia under an IAEA research contract on the possible radiation hazards associated with tin mining industry in Malaysia. The study comprised of the measurement of external radiation levels in various mines, gamma-ray spectrometric analysis of various samples from mines, and measurements of radon and radon daughters concentrations. For radon daughters modified Tsivoglou and Kusnetz methods were used. The study showed that there is, in general, no radiation hazard associated with the tin mining industry in West Malaysia. However, the only likely source that might pose some external radiation hazard is the amang upgrading plant which invariably concentrates either or both 232 Th and 238 U in the final products of the upgrading process. A quantitative and thorough investigation of radiation levels in the amang upgrading industry is necessary to determine the degree of hazard.

Carter, M.W.; Coundouris, A.N.

1993-01-01

The mineral sands industry in New South Wales (NSW) mines and concentrates the heavy minerals ilmenite, rutile, zircon and monazite; principally for export. Mineral sands concentrates contain small quantities of thorium and uranium series radionuclides and therefore are radioactive. The protection of workers, the public and the environment is a responsibility of mine operators. NSW Government Departments administer legislation, grant approvals and specify conditions for radiation protection. A summary of the history and current size of the industry is presented, together with current legislative and licensing activities. The paper reviews available literature on radiation measurements in the East coast mineral sands industry and re-interprets the earlier data in the light of the contemporary methodology of dose assessment. Some unpublished information and the results of some new surveys are also presented. A comparison is made with results that have been reported from Western Australia. Procedures for reducing radiation exposures are discussed and areas of future information needs are suggested. 17 refs., 6 refs., 3 tabs

In the nuclear energy industry, the plants are located far from urban areas and the working environments are generally separate from each other for radiation protection purposes. The health investigation on radiation workers in the nuclear energy industry was carried out using the Todai Health Index questionnaire in 1982, 1983 and 1984. As a control study non-radiation workers on the other several working fields were investigated in the same manner. The results showed that the status of radiation workers in the nuclear energy industry is similar to that of the workers in the other working fields and the THI questionnaire is useful to know health and working status of a group of workers.

Paz, M. José

2014-01-01

In the wake of the commodity boom, “new development strategies” in Latin America are centering on the industrialization of natural resources, thereby questioning the “resource curse” thesis and linking the economic performance of this activity with the institutional framework. In this context, the aim of this paper focusing on the Brazilian oil sector is to analyze the implementation of a resource-based industrialization strategy. After analyzing the Brazilian institutional framework and identifying the key features of a resource-based industrialization strategy, we assess its development and identify its scope and limitations. - Highlights: • We analyze the Brazilian oil sector’s institutional framework. • We analyze the influence of the institutional framework in the Brazilian oil sector performance. • We identify the key features of a resource-based industrialization strategy. • We assess the performance of the Brazilian oil sector and, in particular, its industrialization path

TECHNOLOGY REPRESENTATION IN SOME BRAZILIAN POEMS

Full Text Available Abstract: This article analyses how the universe of technology and labour are depicted in literary terms in some Brazilian poems from the writers Castro Alves, Mario de Andrade and Oswald de Andrade. The poets portray this universe in the following approaches: modern technology dissociated from the Brazilian context painted as traditional and archaic; associated to industrial production and to workers’ exploitation; linked to high class entertainment and as an imported good subjected to central capitalistic economies, facing difficulties to be aggregated to local production.

2016-01-01

In recent years, several economists have argued that the sharp loss of competitiveness of the Brazilian industry was caused by a strong exchange rate appreciation. However, other economists have attributed this loss of competitiveness to the dismal growth of labor productivity in the Brazilian industrial sector. The present paper proposes to estimate the differential impacts of variations in exchange rate and labor productivity on the Brazilian market share of imports measured by the coeffici...

2006-01-01

Optically stimulated luminescence (OSL) has become the technique of choice in many areas of dosimetry. Natural materials like topaz are available in large quantities in Brazil and other countries. They have been studied to investigate the possibility of use its thermoluminescence (TL) properties for dosimetric applications. In this work, we investigate the possibility of utilising the OSL properties of natural Brazilian topaz in dosimetry. Bulk topaz samples were exposed to doses up to 100 Gy of beta radiation and the integrated OSL as a function of the dose showed linear behaviour. The fading occurs in the first 20 min after irradiation but it is <6% of the integrated OSL measured shortly after exposure. We conclude that natural colourless topaz is a very suitable phosphor for OSL dosimetry. (authors)

The Calibration Laboratory of Instituto de Pesquisas Energeticas e Nucleares, IPEN, has already over 25 years been calibrating instruments used in radiation protection and therapy measurements and belonging to hospitals, industries, clinics and other users located in Sao Paulo and in other parts of Brazil. At the present time, the Calibration Laboratory is part of the Radiation Metrology Center and it acts in the Radiation Protection, Radiation Therapy, Nuclear Medicine and Diagnostic Radiology areas, using special set-ups with gamma and beta radiation sealed sources, alpha and beta radiation plane sources and low and intermediate energies of X radiation. Moreover, it has reference instruments for each calibration area with traceability to the Brazilian National Laboratory for Metrology of Ionizing Radiation (secondary standards) and international laboratories (primary standards). The number of tested instruments is increasing annually (from 170 in 1980 to 1871 in 2005), and for the development of new techniques and radiation detectors the continuous improvement of the existing calibration methods is necessary, as well as the establishment of new calibration services to be offered by the Calibration Laboratory for Brazilian and South American users. The objective of this study is to show the evolution of the calibration service developed at IPEN, describing the applied methods and the calibrated instruments types. The quality system implantation process following the basis of the NBR IEC/ISO 17025 standard is also presented with some tools used in the calibration procedures. (Author)

Assessing unregulated ionizing radiation exposures of U.S. populations from conventional industries

International Nuclear Information System (INIS)

Pennington, Charles W.

2006-01-01

During the latter twentieth century, the public learned to fear perceived threats from emerging technologies. Concern about ionizing radiation became a persistent fear, causing protracted and often pointless debate. The twenty-first century offers new opportunities for this fear to cause public and political upset. Citizens and politicians know little about 'normal' radiation exposures caused by conventional industries. This paper summarizes ionizing radiation exposure assessments of several such industries, showing they deliver multiples of background radiation annually to millions of people, with even higher subpopulation doses due to lognormally distributed exposures. Such information may be useful in educating the public and in supporting comparative assessments or other forms of research on potential sources of public radiation exposure in the twenty-first century. By exposing people to information about normal radiation, we may hope to avoid some unfortunate policies and unnecessary regulatory responses, while abating needless public fear during this technologically challenging century

Radiation and the vegetable industry

International Nuclear Information System (INIS)

Roberts, P.B.

1984-01-01

The possible uses of irradiation in the vegetable industry are considered. Interest has been increasing because of possible bans on chemical fumigants and clearance of irradiation as an acceptable process, up to certain dose limits, by Codex Alimentarius and the US FDA. Inhibition of sprouting in potatoes and onions would be one possibility for exploitation. However, the main incentive for vegetable irradiation would be as a quarantine treatment for exported products. The shelf-life of a few vegetables could also be increased by combining radiation with heat treatments. Costs in New Zealand and consumer attitudes are briefly considered

Full Text Available Founded in 1921, the company currently known as Lupo S/A is one of the most ancient textile and clothing industries in Brazil. In this article we aim to describe the general lines of the trajectory of this family company, currently producing socks, nightwear and sports articles. The focus of this paper is on the analysis of some strategies used by the company along its formation and development process, and, particularly, the way these strategies made possible the productive restructuring associated to the overcoming of the strong crisis which began in the end of the 80's and early 90's, contributing to its recent consolidation in the clothing industry. The leading hypothesis of the study is that pioneering connected to a strong organizational culture that has been formed and constructed since its foundation and that was reestablished in a more recent management were the factors which were responsible for the advances able to generate an innovation environment in products as well as in processes and management. The theoretical reflection selected to subsidize the cognitive construction of the study of the company is based on the historical approach of the development of the textile industry in Brazil and in studies about the importance of the action of the entrepreneur, in the role of the organizational culture and LORENZO, H.C. & CAÍRES, A.C.R. of innovation to choose strategies in companies. The research involved the analysis of documents and data of the company, as well as interviews with directors and employees. The results show a traditional company model, but also show the presence of a very advanced entrepreneurial dynamic. Modern world – known as a fordist industrial model – could already be noticed in the company when this production pattern was not clearly defined yet in the Brazilian industry. Nowadays, the company faces the challenge of globalization and the open competition in the international market which brings the rivalry

The paper presents the Brazilian Nuclear Energy Program: its development until the present stage, as well as the organizations and the distribution of responsibilities involved in its execution at the present time. The nuclear power policy is established at the Presidency of the Republic and is planned, executed and controlled through the Ministry of Mines and Energy. Directly subject to the Ministry is the Brazilian Nuclear Energy Commission (CNEN), which has regulatory, standardization, licensing, planning and surveillance functions. The nuclear fundamental research and manpower formation are also under CNEN responsibility. Also subject to the Ministry are two companies responsible for the execution of the Programme: the Centrais Eletricas Brasileiras S.A. - ELETROBRAS, which advises on the granting of permits for the construction and operation of nuclear power plants, and the Empresas Nucleares Brasileiras S.A. - NUCLEBRAS, which holds the monopoly of the nuclear fuel cycle in the country, designs and builds nuclear power plants and provides assistance to the electric utilities as well as promotes the participation of the Brazilian industry in the nuclear field. Besides describing the new distribution of regulatory functions given by law to the CNEN, this paper gives special emphasis to the large industrial complex which is in the process of being established with the setting-up of the many NUCLEBRAS subsidiaries in joint-venture with German firms in the nuclear field, as a consequence of the Industrial Cooperation between Brazil and the Federal Republic of Germany in the Field of the Peaceful Uses of Nuclear Energy signed between the two countries on June 27, 1975. The programs for these subsidiaries are presented and their participation in the Brazilian Nuclear Energy Programme is discussed. The technology transfer aspects of the industrial activities are also discussed, based on the Government's policy on the subject [es

The use of renewable alternative sources of energy in the world has been growing in the last few decades due to concerns about dependence on fossil sources and to environmental reasons, related to climatic change and its effects on mankind. Tax and/or financial incentives have been instituted for the population, to have access to renewable source technologies, and for the local equipment industry, to develop more quickly. In Brazil, the PV (photovoltaic) equipment to convert solar into electricity is more often used in low income rural communities, located distant from the grid network. However, since there is no currently specific regulatory incentive mechanism for this source in the country, the Brazilian PV equipment industry has not made great advances and the market is largely dominated by multinationals. Against this background, this work has as objective to analyze the current PV equipment industry in Brazil, in such way that the obtained information can aid in a future elaboration of a national program development to promote the use of this technology, stimulating the domestic industry and reducing the dependence on imported equipment.

Radiation protection and personnel safety in industrial radiography

International Nuclear Information System (INIS)

Banerjee, Alok Kumar

2015-01-01

Due to availability of a variety of radioisotopes from BRIT, a considerable number of industrial organizations have come up in India which employ radiation sources in one form or the other. More such organizations may come up in the near future due to the 'Make in India' policy of the Government. All ionizing radiations, whether electromagnetic (gamma- ã ) or corpuscular (particles of alpha-á, or beta-â-), and neutrons (0n1) are harmful to the human body. The damage done by radiations is sinister as human senses are not capable of detecting even lethal doses of radiation. The dose of radiations absorbed by human body which take into account the biological effectiveness of different types of radiations as noted above. The overall outcome of exposure to radiation is initiated by damage to the cells of the organism. The effects of radiation may be deterministic or stochastic, early or late, of somatic or genetic type. The somatic effects (physical) can either be immediate or delayed when the whole body is acutely irradiated with radiation doses. All countries including India have brought their national laws/standards on ionizing radiation in line with the ICRP codes. The conditions for registration, transport, storage, protection and use of radiation sources have been laid down in regulations. The purpose of practical protection against radiation is to prevent any individual receiving a harmful dose. Radiation measurement Instruments like dose meter, pocket dosimeter, NaI(Tl) scintillation detector and recording instruments such as film/TLD badge have been briefly described

PERCEPTION OF UNCERTAINTY AND OPERATIONAL PERFORMANCE OF THE BRAZILIAN INDUSTRY FROM 2007 TO 2009

Directory of Open Access Journals (Sweden)

Marta Sambiase Lombardi

2010-11-01

Full Text Available This article poses to explore the relationship between the manager´s perception of uncertainty and the Brazilian industry´s operational performance during the period from 2007 to 2009. This timeframe was chosen because it comprised both positive and negative cycles of the global economic panorama, and thus capable of interfering in the manager´s perception of uncertainty and consequent business strategies. Periods of market fluctuations and more dynamic and complex business environments clearly demonstrate that managerial models which are applicable to static or predictable scenarios, become fragile and of dubious applicability; that is, practices adopted and described in business administration bibliographies might not produce expected results.  A key factor for sound performance is the positioning of companies in relation to future planning (Knight, 2002, the latter defined as actions taken by the entrepreneur given a certain degree of uncertainty, inherent to the management activity.  The relationship between uncertainty and corporate performance has been studied, at least, ever since Knight in 1921. The author affirmed that we live in a world of change and in a world of uncertainty. The level of entrepreneur trust from the National Industry Confederation represented the perception of uncertainty, whilst operational performance was formed as of industrial production and employment IBGE indexes. Results demonstrate that both constructs have equivalent movements during the course of the period, presenting a positive correlation. Key-words: Uncertainty. Operational performance. Trust.

The author uses the Michael Porter framework, (from the University of Harvard), about the 'Competitive Advantage of Nations', as a theoretical instrument to analyze the Brazilian oil industry. The document studies, specifically, the related and supporting industries, one of the four determinants that, according to the author, promote the creation of national competitive advantages; the others are: the factors conditions; the demand conditions; and the firm strategy, structure and rivalry. The study aims at building a general view of competitiveness for the so called supply industries to the oil sector, which have a fundamental role in this model. Although Brazil has developed, with the leadership of PETROBRAS, a complex industrial system, this structure of related and supporting industries will have to face new challenges, having to improve efficiency, reduce costs and redefine its global strategies.

In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

1993-01-01

A general review of radiobiology, immunology system,mechanism of biological effect of radiation and their biological damaging on cells and organs and specifically radiation effects on humoral immune system are given. The purpose is investigating the side effects of occupational exposures caused by ionizing radiation, and reviewing the decreasing probability of humoral immune responses in industrial radiographers. Generally, it measures the following humoral factors of industrial radiographers by value of different exposures: 1-Measuring immunoglobulins serum which consist of IgM, IgG, IgA, IgE. 2-Electrophoresis of serum proteins to investigate gamma globulins changes and also the changes occur in serum globulins after exposure. 3-Investigating the titration of isohem glutins serum (or natural immunoglobulins) that is mostly from IgM. 4-Measuring the above experiments on health control personnel who have not exposed to occupational or biological radiation effects. 5-Comparing the results of the two groups by statistical analysis. 6-Trying to relate the exposure to the information obtained from the above experiments. 7-Finally, to obtain this response whether mutation as low dose of radiation as investigated in this project is a threatening factor to the health and immunity of industrial radiographers

Applications of radiation within the wine industry

Wilson, K.J.; Moran, G.; Boreham, D.

2003-01-01

The objective was to test the feasibility of taint removal in industrial wines through the use of radiation. The process used the cobalt-60 source in the McMaster University Nuclear Reactor. When wine, composed mainly of water (∼87%), alcohol (∼10%), acid (∼2%), and anthrocyanins/tannins (∼0.1%), is irradiated, water molecules are hydrolyzed generating free radicals in solution. These free radicals are oxidizing agents that will oxidize other molecules in the wine. The focus has been a specific taint introduced into 2000-2001 vintages by the Asian lady-bird beetle (Harmonia Axyridis) whose population has increased dramatically of late. This taint - thought to be a methoxy-pyrazine - is detectable by taste in 1-2 parts per trillion (ppt). Preliminary sensory evaluation has shown that radiation dramatically improves tainted wines by eliminating the lady beetle taint. Chemical tests have indicated that radiation is acting as an oxidizing agent, reducing levels of SO 2 (introduced into wines to prevent oxidation) by nearly 40-70%. Research ongoing involves the detection of the taint (the implicated methoxy-pyrazine) by mass spectrometry as a taint assessment tool, and an indicator that radiation has removed the taint

This article discusses the importance of the industrialization of Brazilian shale based on factors such as: security of the national energy system security, global oil geopolitical, resources available, production costs, oil prices, environmental impacts and the national oil reserves. The study shows that the industrialization of shale always arises when issues such as peak oil or its geopolitics appear as factors that raise the price of oil to unrealistic levels. The article concludes that in the Brazilian case, shale oil may be classified as a strategic resource, economically viable, currently in development by the success of the retorting technology for extraction of shale oil and the price of crude oil. The article presents the conclusion that shale may be the driving factor for the formation of a technology park in Sao Mateus do Sul, due to the city's economic dependence on PETROSIX. (author)

The preparation of enantiomerically pure or enriched substances is of fundamental importance to pharmaceutical, food, agrochemical, and cosmetics industries and involves a growing market of hundreds of billions of dollars. However, most chemical processes used for their production are not environmentally friendly because in most cases, stoichiometric amounts of chiral inductors are used and substantial waste is produced. In this context, asymmetric catalysis has emerged as an efficient tool for the synthesis of enantiomerically enriched compounds using chiral catalysts. More specifically, considering the current scenario in the Brazilian chemical industry, especially that of pharmaceuticals, the immediate prospect for the use of synthetic routes developed in Brazil in an enantioselective fashion or even the discovery of new drugs is practically null. Currently, the industrial production of drugs in Brazil is primarily focused on the production of generic drugs and is basically supported by imports of intermediates from China and India. In order to change this panorama and move forward toward the gradual incorporation of genuinely Brazilian synthetic routes, strong incentive policies, especially those related to continuous funding, will be needed. These incentives could be a breakthrough once we establish several research groups working in the area of organic synthesis and on the development and application of chiral organocatalysts and ligands in asymmetric catalysis, thus contributing to boost the development of the Brazilian chemical industry. Considering these circumstances, Brazil can benefit from this opportunity because we have a wide biodiversity and a large pool of natural resources that can be used as starting materials for the production of new chiral catalysts and are creating competence in asymmetric catalysis and related areas. This may decisively contribute to the growth of chemistry in our country. (author)

Villavicencio, A.L.C.H.; Mancini-Filho, J.; Hartmann, M.; Ammon, J.; Delincee, H.

1997-01-01

Radiation processing of beans, which are a major source of dietary protein in Brazil, is a valuable alternative to chemical fumigation to combat postharvest losses due to insect infestation. To ensure free consumer choice, irradiated food will be labeled as such, and to enforce labeling, analytical methods to detect the irradiation treatment in the food product itself are desirable. In two varieties of Brazilian beans, Carioca and Macacar beans, the radiolytic formation of hydrocarbons formed after alpha and beta cleavage, with regard to the carbonyl group in triglycerides, have been studied. Using gas chromatographic analysis of these radiolytic hydrocarbons, different yields per precursor fatty acid are observed for the two types of beans. However, the typical degradation pattern allows the identification of the irradiation treatment in both bean varieties, even after 6 months of storage

In 2005, Brazil addressed the environmental challenges posed by ballast water through a unilateral regulation, called the Maritime Standard N° 20 (NORMAM-20), applied to all shipping in her waters. This world-leading decision was the culmination of a process that started during the 1990‧s. Here, we summarize how these ballast water regulations were brought in and adopted and present the findings of 10 years of enforcement (2005-2015) in 39 ports along the Brazilian coast. We show that compliance with the Brazilian standard has increased significantly since the regulations were implemented (p < 0.001). After five years of implementation, non-compliance decreased probably reflecting an increase in awareness of the Brazilian Standard and a shift in the shipping industry commitment to minimize and control the spread of invasive species through ballast water. The Brazilian experience shows that very high levels (97%) of compliance with ballast water management regulations can be made to work in a region of global importance to the maritime industry. In the last decade, the rules governing ballast water in Brazil have evolved to address the demands from the maritime community and to provide updates such as imminent requirements for the use of ballast water management systems on board ships. These regulations are rarely cited when ballast water regulations are discussed internationally, yet there is much to learn from the proactive approach taken by Brazil such as what is feasible and enforceable.

Besides generation of electricity from nuclear fuels, one of the objectives of the Atomic Energy Programme in India is development and promotion of applications of radioisotopes and radiation technology in all major fields of human endeavor. The applications of isotopes both as stable and as radioactive and electronic radiation sources is increasing at a rapid pace in all major fields of human endeavor. These applications expanded greatly when it became possible to produce a variety of radioisotopes artificially in nuclear reactors and by bombardment of the targets with high energy particles. With the recent developments in the supporting technologies such as compact electronics, high resolution detectors, fast computers, small reliable neutron tubes, dedicated computer modeling codes and better data interpretation, one can now satisfy the longstanding demand for immediate, accurate and detailed information about the test specimen. As a result of the radioisotope programme, the country has a strong infrastructure in various fields including applications in industry. One major area of industrial applications of radioisotopes is their use as sealed radioactive sources and as radioactive tracers for troubleshooting, process control and process vessel design modification. These applications are mostly online, nondestructive and noninvasive. Radioisotope techniques can perform many tasks better, easier, quicker, relatively simply, cost effectively than alternative methods and have no substitutes in many applications, and are used extensively in all areas of industry, research, medicine and agriculture. Sealed source techniques of radioisotope applications provide valuable, non destructive and noninvasive insight to the process and plant problems. These are either supplementary to or more convenient than tracer techniques. These applications do not require much preparation time and hence can be carried out at short notice. The use of these techniques is growing steadily

The recent crisis in electricity supply raised in all Brazilians the necessity in improving energy resources. The expansion of generation capacity cannot be seen as the unique solution: optimise what is available already is at least so important than to expand. The rational use of energy resources brings additional benefits as reduced environmental impacts, replacement of equipment and following incentives to industry and employment. Promote coordinated actions has been challenging in several places. In Brazil, GERBI Program aims to address several market barriers, developing activities in different fronts: service suppliers' qualification, preparation of financial agents and, mainly, engage industrial end users for improved solutions. The paper presents GERBI Program structure as an incentive to rational energy use in industrial facilities, focused on GHG emissions reduction. The Program is structured in three main components: energy efficiency projects development, supporting industries to implement better practices and efficient technologies, development of CDM candidate projects, making use of 'carbon credits' resulted from reduced emissions, and training and qualification.

Industrial radiography is a method for non destructive testing of homogeneity of various materials based on different absorption of radiation in different material. X and γ radiation are the most often used. Detrimental effects of radiation are observed since its discovery. In order to prevent harmful effects of radiation without unduly limitations of its use, International Commission on Radiological Protection in collaboration with International Atomic Energy Agency have developed International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources, Safety Series No 115, adopted in 1996. based on ICRP recommendations from 1991. Besides a lot of changes in radiation protection concept and philosophy, decrement of annual dose limits for occupational exposure from 50 to 20 mSv. (author)

Industrial fiberscopes incorporating pure silica core image guides have been extensively used for remote visual inspection in radiation fields including nuclear power plants, owing to their superior radiation resistivity. The authors have been intensively conducting R and D on improving radiation resistivity of pure silica core image guides. This paper reports the results of experiments to compare the effects of core materials on radiation resistivity and to investigate the dependence of radiation resistivity on total dose, does rate, and support pipe material. The results confirmed the superior radiation resistivity of the core material containing fluorine at any irradiation condition and indicated the existence of a critical dose rate at which radiation-induced deterioration was stabilized. No difference in radiation resistivity attributable to support layer material was observed. (author)

Full Text Available A spatial price equilibrium model of the international cotton sector was used to analyze the impacts of the Port of Salvador improvements on the Brazilian cotton industry and world cotton trade. The port of Salvador is undergoing relevant improvements in its facilities and physical structure. As a result of these improvements, the port of Salvador is expected to become more competitive and attract ocean shipping companies which are willing to export products directly to Asian importing markets. Scenarios with different reduction in export cost for the port of Salvador were examined. For all scenarios, the new direct ocean shipping lines were found to be important for the cotton exporters in Brazil, especially for the producers in the state of Bahia. In addition, results suggested that the state of Bahia would have the potential of becoming the largest cotton exporting state in Brazil.

This article presents the main regulatory changes that occurred in the Brazilian power sector in 2009, along with the impacts these changes caused on the market, especially related to small hydropower (<30 MW). This study addresses regulatory issues based on inventory studies and records of basic projects, changes related to the compensation of the assured energy of SHPs in the Brazilian energy reallocation market, the socio-economic impact resulting from the construction of SHPs, SHPs in alternative resource auctions and finally the general outlook for the growth scenario for SHPs in Brazil according to the ten-year plan (2010-2019). The overall conclusions of this investigation were that the 2008/2009 biennium was a period of great changes in the regulation of small hydropower plants in Brazil, and the SHP market has shown maturity. Additionally, despite SHP being a type of technology that is completely dominated by domestic industry, in recent years, they have experienced policy disincentives caused by changes to rules that inhibit their growth. - Highlights: → Main regulatory changes in Brazilian Power Sector that have occurred in 2009. → The impact of these changes caused on market, especially about SHPs (<30 MW). → The Brazilian growth scenario for SHPs according to the ten-year plan (2010-2019). → 2008/2009 biennium was a period of changes in the Brazilian regulation of SHPs. → SHP is a type of technology that is completely dominated by domestic industry.

Treatment of Municipal and Industrial Waste by Radiation Processing

International Nuclear Information System (INIS)

Abdelaziz, M.E.

1999-01-01

In recent years the effort in science and technology is shifting from conventional technologies preventing the pollution of air, water and soil, towards processing by gamma or by electron beam (EB) irradiation in order to prevent pollution, rather than curing the problems caused by production processes, which are not optimized with regard to pollution control. Radiation processing may help to improve the environmental situation in two aspects : It provides alternatives to conventional technologies for the cleaning of air, flue gases and water,...etc, and it also helps to realize clean processes for preventing pollution in the first place. This paper will outline the basic principles of radiation processing for waste streams of environmental relevance, will summarize the state-of -the-art in environmental applications of radiation processing to show both the advantages and the limitations of the radiation processing of waste streams, and to highlight the environmental and economic benefits of clean processes made possible by radiation processing applied to municipal and industrial waste. Reference is made to gamma and EB radiation sources, and description of new technologies is presented

Radiation Protection and NORM Residue Management in the Titanium Dioxide and Related Industries

2012-08-15

The Fundamental Safety Principles (IAEA Safety Standards Series No. SF-1), together with Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (IAEA Safety Standards Series No. GSR Part 3 (Interim)), set out the principles and basic requirements for radiation protection and safety applicable to all activities involving radiation exposure, including exposure to natural sources of radiation. The Safety Guides on Occupational Radiation Protection in the Mining and Processing of Raw Materials (IAEA Safety Standards Series No. RS-G-1.6) and Management of Radioactive Waste from the Mining and Milling of Ores (IAEA Safety Standards Series No. WS-G-1.2) provide guidance on the control of exposure of workers and members of the public to naturally occurring radioactive material (NORM) in industrial activities involving the exploitation of minerals. This guidance applies irrespective of whether the minerals are exploited for their radioactivity content. The titanium dioxide and related industries constitute one of several industry sectors for which the radioactivity content of the minerals and raw materials involved is too small to be of commercial value but is large enough to warrant consideration by the regulatory body concerning the possible need to control exposures of workers and members of the public. This Safety Report has been developed as part of the IAEA's programme to provide for the application of its safety standards in the field of radiation, transport and waste safety. It is a compilation of detailed information on the processes and materials involved in the titanium dioxide and related industries and on the radiological considerations that need to be taken into account by the regulatory body when determining the nature and extent of radiation protection measures to be taken. This is consistent with the graded approach to regulation, in terms of which the application of the requirements of the safety standards is

An attempt was made to apply radiation techniques in the treatment of industrial wastewater from a dairy, brewery and sugar factory. For degradation of pollutants present in the wastewater, the following methods were used: irradiation, irradiation combined with aeration, ozonation, and combined irradiation and ozonation. For all three types of wastewater, the best method among these listed above appeared to be the method of irradiation combined with ozonation. Most degradable was the wastewater produced in sugar factories, and the least biodegradable appeared to be dairy wastewater. Depending on the dose of ozone and radiation, a maximum 60% reduction of COD was obtained. No effect of the wastewater aeration on its degradation by radiation was found. Changes in the content of mineral compounds were observed in none of the cases. The process of biological treatment of wastewater was carried out in a low-loaded, wetted bed. Pretreatment of the wastewater had no significant effect on the improvement of the biological step operation. Some effect was observed only in the case of the wastewater coming from a sugar factory. For medium concentrated wastewater from food industry, it is not economically justified to apply the pretreatment with the use of ionising radiation. (orig.)

This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices) and 19.77% (market prices) of Brazilian GDP. The tax burden of agribusiness (20.68%) was higher than that of other sectors (13.59%), despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

The purpose of this work was to obtain a broad knowledge of the circumstances under which activities involving ionizing radiations are held at brazilian academic institutions. Around 90 institutions (universities and isolated schools of both public and private sectors) were invited, by mail, to answer an inquiry with questions from technical to legal aspects of their activities with radiations. Information received from 2/3 of institutions contacted, permitted conclusions as: there is a wide ignorance about radioprotection procedures and legislation, although few universities maintain some efficient radioprotection staff; there is a need for the establishment of a standard radioprotection text dedicated to those specific activities of the sector.

Methods for estimating the risk of radiation induced cancer mortality to members of the public are outlined for each element of the nuclear power industry - reactor accidents, routine releases from nuclear plants, transport, mining and milling of uranium, and escape of buried radioactive waste (high level and low level). The results are compared with mortality risks from the air pollution and chemical carcinogens released into the ground in generating the same amount of electricity by coal burning - the latter are thousands of times larger. Radiation from nuclear power is also 1,000 times smaller than that from radon in homes. The amount of money spent to avert a death from nuclear power radiation is in the billion dollar range, whereas lives could be saved from radon in homes for 0.00001 times that cost. Medical screening and highway safety programs can save lives for a similarly low cost

Although most of the sky-shine radiation levels in industrial radiography are below regulatory limits, sky-shine radiation could make a valuable contribution to the total radiation level near shielding facility with little shielding and open field without shielding. Therefore sky-shine radiation should be thoroughly predicted and supervised with the ALARA principle. In this study, we simulated sky-shine radiation for mobile irradiators using MCNP and newly suggested the equation for calculating sky-shine radiation. Also these results were applied to developing Korean regulatory guidance about industrial radiography and to recommending the requirement of the facility design, controlled or supervised area at work places.

Radiation Processing of Natural Polymers for Industrial Applications

Hegazy, E.A.

Radiation induced degradation technology is a new and promising application of ionizing radiation to develop viscose, pulp, paper, food preservation, pharmaceutical production, and natural bioactive agents industries. Controlling the degree of degradation, uniform molecular weight distribution, saving achieved in the chemicals (used in conventional methods) on a cost basis, and environmentally friendly process are the beneficial effects of using radiation technology in these industries. However, for some development countries such technology is not economic. Therefore, a great effort should be done to reduce the cost required for such technologies. One of the principle factors for reducing the cost is achieving the degradation at low irradiation doses. The addition of some additives such as potassium per-sulfate (KPS), ammonium per-sulfate (APS), or H 2 O 2 to natural polymers (carboxy-methylcellulose (CMC), chitosan, carrageenan and Na-alginate) during irradiation process accelerates their degradation. The highest degradation rate of polysaccharides obtained when APS was used. The end product of irradiated CMC, chitosan, carrageenan and Na-alginate may be used as food additive or benefited in agricultural purposes. On the other hand, radiation crosslinking of PAAm or PNIPAAm is affected by the presence of natural polymer like CMC-Na and carrageenan due to their degradability which could be controlled according to its concentration in the bulk medium and irradiation dose. Accordingly, the gel content, thermo-sensitivity (LCST) and swelling properties of PNIPAAm based natural polymers could be controlled. The swelling of the prepared copolymer hydrogels was investigated for its possible use in personal care articles particularly diapers or as carriers for drug delivery systems. The prepared crosslinked copolymers possessed high and fast swelling properties in simulated urine media and the swelling ratios of CMC-Na /PAAm gels in urine are acceptable for diaper

Propolis is a natural product from vegetable origin that is generally collected from beehives. This product is well-known for its heath benefits attributed to its biological properties. On the other hand, Brazilian sugarcane spirit, cachaca, shows increasing interest and importance in the alcoholic beverage segment in many markets in the world. Therefore, it was evaluated the addition of propolis into cachaca and the effect of ionizing radiation on propolis compounds with biological activity. Samples of cachaca with propolis used in irradiation experiments were prepared from cachaca (40 deg GL) composed with propolis (0,1 %). Eight treatments, with four repetitions each, were carried out in this study. Three doses of ionizing radiation from electron beam and gamma radiation by 60 Co were applied on the cachaca samples, i.e. 0.5, 1.0, and 2.0 kGy, aiming to accelerate the aging of the cachaca samples. The spirits samples were stored for two periods (immediately after the radiation treatment and 30 months after the treatments) and their phenolic compounds contents were analyzed. Phenolic compounds contents were statistically different between both storage times of the cachaca. The samples of cachaca treated with electron beam at 2.0 kGy presented higher reduction in phenolic compounds contents, approximately 6 % in the first analysis and 11 % in the second analysis. In conclusion, the time of storage to promote reduction on the phenolics compounds and the ionizing radiations from electron beams affect more the contents of these compounds than gamma radiation.

The hazards associated with the use of industrial equipment is one of the undesirable by-products of advanced technology. The use of nuclear techniques is a good example. Due to the usefulness of such techniques, one may accept the risks involved if they can be brought down to manageable levels. Most of the nuclear techniques in use in industries in Malaysia require only minimal safety precautions as they make use of only small amounts of radioactive material. However, some large sources are also being used and safety precautions have to be strictly enforced. The management plays a critical role in these industries. The requirements for radiation safety include the monitoring of workers and work areas, the medical surveillance of workers and the provision of barriers and other safety precautions. The management should also look to the training of the workers and be prepared for any emergencies that may arise. (author)

The hazards associated with the use of industrial equipment is one of the undesirable by-products of advanced technology. The use of nuclear techniques is a good example. Due to the usefulness of such techniques, one may accept the risks involved if they can be brought down to manageable levels. Most of the nuclear techniques in use in industries in Malaysia require only minimal safety precautions as they make use of only small amounts of radioactive material. However, some large sources are also being used and safety precautions have to be strictly enforced. The management plays a critical role in these industries. The requirements for radiation safety include the monitoring of workers and work areas, the medical surveillance of workers and the provision of barriers and other safety precautions. The management should also look to the training of the workers and be prepared for any emergencies that may arise.

Radiation response of industrial materials: Dose-rate and morphology implications

International Nuclear Information System (INIS)

Berejka, Anthony J.

2007-01-01

Industrial uses of ionizing radiation mostly rely upon high current, high dose-rate (100 kGy/s) electron beam (EB) accelerators. To a lesser extent, industry uses low dose-rate (2.8 x 10 -3 kGy/s) radioactive Cobalt-60 as a gamma source, generally for some rather specific purposes, as medical device sterilization and the treatment of food and foodstuffs. There are nearly nine times as many (∼1400) high current EB units in commercial operation than gamma sources (∼160). However, gamma sources can be easily scaled-down so that much research on materials effects is conducted using gamma radiation. Likewise, laboratories are more likely to have very low beam current and consequently low dose-rate accelerators such as Van de Graaff generators and linear accelerators. With the advent of very high current EB accelerators, X-ray processing has become an industrially viable option. With X-rays from high power sources, dose-rates can be modulated based upon accelerator power and the attenuation of the X-ray by the distance of the material from the X-ray target. Dose and dose-rate dependence has been found to be of consequence in several commercial applications which can employ the use of ionizing radiation. The combination of dose and dose-rate dependence of the polymerization and crosslinking of wood impregnants and of fiber composite matrix materials can yield more economically viable results which have promising commercial potential. Monomer and oligomer structure also play an important role in attaining these desirable results. The influence of morphology is shown on the radiation response of olefin polymers, such as ethylene, propylene and isobutylene polymers and their copolymers. Both controlled morphology and controlled dose-rate have commercial consequences. These are also impacted both by the adroit selection of materials and through the possible use of X-ray processing

Radiation sterilization technology, cross-linked polymers and curing, food and environmental applications of the radiation is widely used for many years. At the same time, drinking water and wastewater treatment are the part of the radiation technology applications. For this purpose, drinking water and wastewater treatment plants in various countries has been established. In this project, gamma / electron beam radiation treatment is intended to be used for the treatment of alkaloid, textiles and polychlorinated biphenyls (PCBs) wastewater. In this regard, the chemical characterization of wastewater, the interaction with radiation, biological treatment and determination of toxicological properties are the laboratory studies milestones. After laboratory studies, the establishment of a pilot scale treatment plant has been planned. Within the framework of the project a series of dye used in textile industry were examined. Besides the irradiation, the changes in treatment efficiency were investigated by using of oxygen and hydrogen peroxide in conjunction with the irradiation. Same working methods were implemented in the wastewater treatment of Bolvadin Opium Alkaloid Factory as well. In addition to chemical analysis in this study, aerobic and anaerobic biological treatment process also have been applied. Standard reference materials has been used for the marine sediment study contaminated with polychlorinated biphenyls.

The objective of this paper is to inform about the aspects of radiation protection public policies concerning the public spheres and the ordinary population. It is known that information has been considered a very important good in several knowledge areas. However, the efficiency of their transmission mechanisms should be periodically evaluated, checking existing critical and stagnation points. Nuclear area can be mentioned as a historically typical case, where the public policies assume relevant importance as tool for promotion, control and education of the population in general. Considering the polemic nature of such subject, it is clear that there is a need for conducting the construction of educational contents taking in account the educator training necessities. The addressing of radiation protection aspects applied to nuclear techniques conducts, for example, to the awareness on the benefits of radiation and its industrial and medical applications, which are established considering the worldwide adopted basic principles of radiation protection. Such questions, concerned with (or related to) public policies, establish a link between radiation protection and education, themes explored in this article to provide a better view of the current Brazilian scenario.

The monitoring and dosimetry systems used at Industrial Application and Engineering Service Department of the Instituto de Pesquisas Energeticas e Nucleares of the Brazilian Nuclear Energy Commission (GE-IPEN-CNEN/SP) are analyzed,in order to verify the compliance with the condition established by the dose system limitation and the basic radiation protection standards. The criteria about the use of individual dosimetry for persons that work in these facilities are established. In case of an external radiation dosimetry, by using film badge method, a level of 200μGy has been assigned, considering the detection significant threshold. For dose in air due to electromagnetic radiation, using TLD dosimetry of CaSO 4 :Dy a quarter year significant threshold is 101μGy. A symbiosis between the workplace monitoring and the individual monitoring became necessary for optimization purpose. (authors). 5 refs., 2 tabs., 1 fig

Since the discovery of X-rays in 1895, ionizing radiation has been applied in many sectors of society, such as medicine, industry, safety, construction, engineering and research. However, population is unaware of both the applications of ionizing radiation and their risks and benefits. It can be seen that most people associate the terms 'radiation' and 'nuclear energy' with the atomic bomb or cancer, most likely because of warlike applications and the stealthy way radioactivity had been treated in the past. Thus, it is necessary to clarify the population about the main aspects related to the applications, risks and associated benefits. These knowledge can be disseminated in schools. Brazilian legislation for basic education provides for topics such as nuclear energy and radioactivity to high school students. However, some factors hamper such an educational practice, namely, few hours of class, textbooks do not address the subject, previous concepts obtained in the media, difficulty in dealing with the subject in the classroom, phobia, etc. One solution would be the approximation between schools and institutions that employ technologies involving radioactivity, which would allow students to know the practices, associated radiological protection, as well as the risks and benefits to society. Currently, with the increasing application of ionizing radiation, especially in medicine, it is necessary to demystify the use of radioactivity. (author)

Evaluation of radiation protection in the use of radioactive tracers in the oil industry; Avaliação da proteção radiológica no uso de traçadores radioativos na indústria de petróleo

Radioactive tracers have been widely used in the industry to optimize processes, improve product quality, save energy and reduce pollution. The petroleum industry uses sources for radioactive tracers in solid, liquid and gaseous forms to investigate or track the movement of other materials into pipes of inaccessible lines, such as, {sup 3}H, {sup 82}Br, {sup 131}I, {sup 85}Kr, {sup 41}Ar, {sup 14}C, {sup 24}Na, {sup 192}Ir , etc. The work presents the application of radioactive tracers in the area of oil and gas industry and carries out an evaluation of the radiological risk, the doses of radiation, the specific radiological protection procedures, safety and radiological emergency to be followed. It was observed that radiological risks in the use of radioactive tracers involve three aspects: external dose, external contamination and internal contamination. Most of the time the risk of radiation related to the external dose is very low because unsealed radioactive sources have low activity and exposure times are very low during handling. External and internal contaminations appear due to the use of open sources that allow direct contact and even inhalation or ingestion of radioactive material. It was identified that there is no specific Brazilian regulation for radiation protection in radioactive tracers, and the recommendations of the International Atomic Energy Agency - IAEA should be used.

Borges, J.C.

1996-01-01

The Brazilian labour legislation establishes, since 1950, some privileges for people working in activities which imply exposure to ionizing radiations. Comparing the present legal framework with technical radioprotection knowledge, one can detect several incoherences covering: classification of such activities; additional payments; reduced labour journey; more vacations; medical surveillance; early retirements; special norms for women. An analysis of these incoherences lead us to propose a new frame of labour rights and radioprotection norms, coupling Brazilian juridical principles and modern radioprotection knowledge. (author)

Securitization in the Brazilian Banking Industry: An Empirical Study

Directory of Open Access Journals (Sweden)

Umbelina Cravo Teixeira Lagioia

2009-05-01

Full Text Available Securitization is a modality of structured finance which allows a company to raise funds based on its receivables through capital markets. In Brazil, securitization was developed mostly in the form of mutual funds -- the FIDC, which raise money by issuing senior quotas for qualified investors, and subordinated cotes, usually bought by the company that originated the receivables. This paper evaluates the risk and return for both kinds of investors through a stochastic model with two main variables: interest rates and default rates. The model is still sensible to the characteristics of the fund, like the amount of subordinated cotes, the type of asset being securitized; and the amount of receivables in relation to the assets. Regarding the case of senior cotes, the risk of returns under the basic level of interest rates is highly improbable; and in the case of subordinated cotes, the risk of returns under the basic interest rate may be considered still low, due to the high spreads observed in the Brazilian financial market. The simulations indicated that under historically mean interest rate volatility the default rates are the main component of the total risk. Accordingly to the developed analysis of international standards of regulation, the Brazilian Central Bank imposes very strong capital requirements to banks that securitize their assets and purchase the corresponding subordinated cotes.

Regulation of the natural gas distribution sector: a comparison of Brazilian and Colombian industries; Regulacao do setor de distribuicao de gas natural: uma comparacao dos casos brasileiro e colombiano

Domingues, Mariana Peralva; Ferraro, Marcelo Colomer [Universidade Federal do Rio de Janeiro (UFRJ), RJ (Brazil)

2008-07-01

The Bolivia oil industry nationalization in 2006 and the high price of oil on the international market called the public and government attention to the problems of the natural gas industry regulation in Brazil. Recently, the establishment of a specific law for the natural gas industry had been debated in academic circles and in government institutions. In Brazil, the absence of an integrated energy policy and the absence of a homogeneous regulatory framework interfere with natural gas industry development, especially in distribution. Thus, the objective of the work will be contrast the Colombia distribution natural gas regulatory structure sector to the Brazilian natural gas regulatory framework. The comparison of the Brazilian regulatory framework and the Colombian natural gas regulation shows that the existence of different kinds of concession contracts in distribution is one of the explanations for the different levels of investment in Brazil. The contract with exclusive right to explore the distribution service in geographic territories also contributes to explain the low coverage rate of public distribution companies. Thus, the rapid expansion of the natural gas distribution network in Colombia after the regulatory reforms shows the importance of the establishment of a regulatory structure to push private investment. The Colombian case can be considered a good model for other countries in South America, especially to the natural gas distribution regulation. (author)

Radiation doses inside industrial irradiation installation with linear electron accelerator

2015-01-01

Aceletron Industrial Irradiation Company is the unique installation in South America to provide industrial irradiation service using two linear electron accelerators of 18 kW and 10 MeV energy. The electron beam technology allows using electrons to irradiate many goods and materials, such as hospital and medical equipment, cosmetics, herbal products, polymers, peat, gemstones and food. Aceletron Company uses a concrete bunker with 3.66 m of thickness to provide the necessary occupational and environmental radiation protection of X-rays produced. The bunker is divided in main four areas: irradiation room, maze, tower and pit. Inside the irradiation room the x-rays radiation rates are measured in two ways: direct beam and 90 deg C. The rates produced in the conveyor system using 10 MeV energy are 500 Gy/min/mA and 15 Gy/min/mA, respectively. For a 1.8 mA current, the rates produced are 900 Gy/min and 27 Gy/min, respectively. Outside the bunker the radiation rate is at background level, but in the tower door and modulation room the radiation rate is 10 μSv/h. In 2014, during a routine operation, an effective dose of 30.90 mSv was recorded in a monthly individual dosimeter. After the investigation, it was concluded that the dose was only in the dosimeter because it felt inside the irradiation room. As Aceletron Company follows the principles of safety culture, it was decided to perform the radiation isodose curves, inside the four areas of the installation, to know exactly the hotspots positions, exposure times and radiation doses. Five hotspots were chosen taking into account worker's routes and possible operational places. The first experiment was done using a package with three TLD and OSLD dosimeters to obtain better statistical results. The first results for the five hotspots near the accelerator machine showed that the radiation dose rates were between 26 Gy/h and 31 Gy/h. The final measurements were performed using a package with one TLD and one OSLD

The application of radiation technology in industrial processes: current and future perspectives

International Nuclear Information System (INIS)

Silverman, J.

1975-01-01

The development of nuclear power has been responsible for many by-products, among them radioactive fission products. In the late 1940's and early 1950's considerable efforts were made to develop industrial processes that could make use of the fission products in large quantities. Although some fission products are utilized today, the scale does not approach the quantities that will be produced in a nuclear economy. The efforts have not been a failure, however, and the research to develop industrial processes has created markets, not for the fission products as one had hoped, but for the radioisotope Cobalt-60 produced by neutron capture in a nuclear reactor, and for accelerators - machines that produce radiation in a controlled manner. Success in finding uses for the major fission products may yet come, as research continues in the radiation chemistry and radiation biology fields. Radiation processing is now a vigorously expanding area because of sharp increases in the reliability of electron beam generators, sharp drops in the unit cost of both electron beam power and electron beam energy, significant advances in radiation chemistry leading to lower dose requirements and increased engineering knowledge and practical experience. he principal reasons for its bright future promise arise from expectations of further sharp decreases in the unit cost of electron beam energy and from the recent successful adoption of radiation on a large scale for cross linking of telephone wire insulation in the United States.

China is pursuing the use of radiation technology as part of its wastewater treatment methods to further efforts to manage industrial waste in an environmentally friendly way. “Treating the water that comes from our industries is very important, so we have been doing this for a long time. Now we want to become better at making our water cleaner,” said Jianlong Wang, Vice-President of the Institute of Nuclear and New Energy Technology (INET) at Tsinghua University in Beijing. “We are receiving a lot of support from the IAEA to use electron beam based technologies to help us get rid of various water pollutants that the other methods cannot do on their own.”

The Brazilian nuclear power manpower development programme

Barbalho, A.R.; Spitalnik, J.; Machado, J.B.

1983-01-01

Since the early stages of decision making, manpower availability has been recognized to be a key factor for the implementation of Brazil's nuclear power programme. Though care has been given to securing an industrial base and financial resources, the consequences of a lack of sufficient qualified manpower could be critical for the success of the whole programme. The broad scope of the Brazilian nuclear power programme which, as a main concept, aimed at establishing in the country a complete fuel cycle industry together with the construction of nuclear power plants, added another burden to the already complex task of providing appropriate human resources when advanced technologies are introduced in a developing country. Thus, not only the work-force required for nuclear power plant operation but also that needed for plant design, component manufacture, fuel cycle plant design and operation, had to be made available in number and qualification in accordance with the standards of the nuclear industry. The feasibility of the Brazilian programme depended on a complete transfer of technology, essentially achieved through personnel training. Again, the process of manpower preparation for an efficient know-how transfer required careful planning, and the great difficulty in its implementation was the lack of reliable experience at the time.

International Nuclear Information System (INIS)

1990-01-01

The use of radiation sources of various types and activities is widespread in industry, medicine, research and teaching, and is increasing yearly. The safety record has been admirable, although incidents have occurred where loss of control of radiation sources has given rise to unplanned exposures to workers, medical patients and members of the public, sometimes with fatal results, while in other situations exposure may not have been as low as reasonably achievable. This publication is intended as a practical aid for all concerned with operational radiation protection connected with the use of radiation sources in industry, medicine, research and teaching, from the point of view of both the user of such sources and the regulatory bodies.

Calculating Historical Contributions To Climate Change. Discussing The 'Brazilian Proposal'

International Nuclear Information System (INIS)

Hoehne, N.; Blok, K.

2005-01-01

This paper discusses methodological issues relevant to the calculation of historical responsibility of countries for climate change ('The Brazilian Proposal'). Using a simple representation of the climate system, the paper compares contributions to climate change using different indicators: current radiative forcing, current GWP-weighted emissions, radiative forcing from increased concentrations, cumulative GWP-weighted emissions, global-average surface-air temperature increase and two new indicators: weighted concentrations (analogue to GWP-weighted emissions) and integrated temperature increase. Only the last two indicators are at the same time 'backward looking' (take into account historical emissions), 'backward discounting' (early emissions weigh less, depending on the decay in the atmosphere) and 'forward looking' (future effects of the emissions are considered) and are comparable for all gases. Cumulative GWP-weighted emissions are simple to calculate but are not 'backward discounting'. 'Radiative forcing' and 'temperature increase' are not 'forward looking'. 'Temperature increase' discounts the emissions of the last decade due to the slow response of the climate system. It therefore gives low weight to regions that have recently significantly increased emissions. Results of the five different indicators are quite similar for large groups (but possibly not for individual countries): industrialized countries contributed around 60% to today's climate change, developing countries around 40% (using the available data for fossil, industrial and forestry CO2, CH4 and N2O). The paper further argues including non-linearities of the climate system or using a simplified linear system is a political choice. The paper also notes that results of contributions to climate change need to be interpreted with care: Countries that developed early benefited economically, but have high historical emission, and countries developing at a later period can profit from developments

Radiological protection, safety and security issues in the industrial and medical applications of radiation sources

Science.gov (United States)

Vaz, Pedro

2015-11-01

The use of radiation sources, namely radioactive sealed or unsealed sources and particle accelerators and beams is ubiquitous in the industrial and medical applications of ionizing radiation. Besides radiological protection of the workers, members of the public and patients in routine situations, the use of radiation sources involves several aspects associated to the mitigation of radiological or nuclear accidents and associated emergency situations. On the other hand, during the last decade security issues became burning issues due to the potential malevolent uses of radioactive sources for the perpetration of terrorist acts using RDD (Radiological Dispersal Devices), RED (Radiation Exposure Devices) or IND (Improvised Nuclear Devices). A stringent set of international legally and non-legally binding instruments, regulations, conventions and treaties regulate nowadays the use of radioactive sources. In this paper, a review of the radiological protection issues associated to the use of radiation sources in the industrial and medical applications of ionizing radiation is performed. The associated radiation safety issues and the prevention and mitigation of incidents and accidents are discussed. A comprehensive discussion of the security issues associated to the global use of radiation sources for the aforementioned applications and the inherent radiation detection requirements will be presented. Scientific, technical, legal, ethical, socio-economic issues are put forward and discussed.

Radiation protection principles applied to conventional industries producing deleterious environmental effects

Tadmor, J.

1980-01-01

Comparison of the radiation protection standards, for the population at large, with the conventional pollutants ambient standards, reveals differences in basic principles which result in more relaxed ambient standards for conventional pollutants and consequently, the penalization of the nuclear industry, due to the increased cost of its safety measures. It is proposed that radiation protection principles should be used as a prototype for pollutants having harmful environmental effects and that radiation health physicists should be active in the application of these principles of population protection. A case study of atmospheric release of SO 2 , under different conditions, is analyzed, to emphasize the importance of consideration of the size of the exposed population. (H.K.)

[Brazilian guidelines for marketing baby food: history, limitations and perspectives].

Monteiro, Renata

2006-05-01

The objective of this paper is to present and discuss Brazilian policy concerning actions to protect breastfeeding, especially the history, international and national background, limitations, and perspectives of the Brazilian Guidelines for the Marketing of Baby Food, Pacifiers and Bottles. The Brazilian Guidelines, which play a crucial role in protecting breastfeeding against industry marketing strategies, were based on the International Code of Marketing of Breastmilk Substitutes, proposed by the World Health Organization in 1981. The first version of the Brazilian Guidelines was released in 1988, and there were subsequent revisions in 1992 and 2001/2002. In 2006, the Guidelines became national law. However, the strides made over this period in terms of regulation have been few because the law is not always observed. Thus, it is essential that all actors involved, including government officials, manufacturers and sellers of baby food and other baby products, teaching and health professionals and their associations, international bodies, and non-governmental organizations make a commitment to enforce the current law.

Gamma-rays utilized as a food-processing treatment to eliminate insect contamination is well established in food industries. Recent troubles in Brazilian cereal bars commercialization require a special consumer's attention because some products were contaminated by insects. To solve the problem, food-irradiation treatment was utilized as a safe and effective solution. The final product was free of insect contamination. The aim of this study was to determine the best radiation dose processing utilized to disinfestations and detect some change on sensorial characteristic by sensorial analysis in cereal bars. In this study, three different kinds of cereal bars were purchased in Sao Paulo (Brazil) in supermarkets and irradiated with 1.0, 2.0 and 3.0 kGy at 'Instituto de Pesquisas Energeticas e Nucleares' (IPEN-CNEN/SP). The samples were treated with ionizing radiation using a 60 Co gamma-ray facility (Gammacell 220, A.E.C.L.). That radiation doses were used successfully as an anti-insect treatment in the cereal bars, since in some food industries doses up to 3.0 kGy are used to guarantee at least a dose of 1.0 kGy in internal cereal bars package. Sensorial analysis was necessary since cereal bars contain ingredients very sensitive to ionizing radiation process

Anthropotechnological analysis of industrial accidents in Brazil.

Binder, M. C.; de Almeida, I. M.; Monteau, M.

1999-01-01

The Brazilian Ministry of Labour has been attempting to modify the norms used to analyse industrial accidents in the country. For this purpose, in 1994 it tried to make compulsory use of the causal tree approach to accident analysis, an approach developed in France during the 1970s, without having previously determined whether it is suitable for use under the industrial safety conditions that prevail in most Brazilian firms. In addition, opposition from Brazilian employers has blocked the proposed changes to the norms. The present study employed anthropotechnology to analyse experimental application of the causal tree method to work-related accidents in industrial firms in the region of Botucatu, São Paulo. Three work-related accidents were examined in three industrial firms representative of local, national and multinational companies. On the basis of the accidents analysed in this study, the rationale for the use of the causal tree method in Brazil can be summarized for each type of firm as follows: the method is redundant if there is a predominance of the type of risk whose elimination or neutralization requires adoption of conventional industrial safety measures (firm representative of local enterprises); the method is worth while if the company's specific technical risks have already largely been eliminated (firm representative of national enterprises); and the method is particularly appropriate if the firm has a good safety record and the causes of accidents are primarily related to industrial organization and management (multinational enterprise).

Capsicum peppers are known as a source of capsaicinoids, phenolic compounds and antioxidants. Brazilian Capsicum peppers are important spices used in foods worldwide. However, little information is available on the chemical composition and antioxidant activity of these peppers. Capsaicin, dihydrocapsaicin, total phenolic compounds and antioxidant activity were investigated in extracts of three Brazilian peppers: Capsicum frutescens, C. chinense and C. baccatum var. pendulum, in two different harvest years and at two ripening stages. The bioactive compound content was dependent on harvest year, and changes in the concentration profiles were found for capsaicin. Mature fruits of C. chinense harvested in the first year had the highest capsaicin concentration (2.04 mg g -1 fresh pepper), and mature fruits of C. frutescens harvested in the same first year had the highest dihydrocapsaicin content (0.95 mg g -1 fresh pepper). Mature fruits of C. frutescens harvested in the first year showed the major total phenolic compound content (2.46 mg g -1 fresh pepper). The total phenolic compound content was directly related to antioxidant activity. Our results suggest that phenolic compounds significantly contribute to the antioxidant activity of the investigated peppers. Also, these data add valued novel information that enhances current knowledge of Brazilian pepper fruits. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Brazil has approximately 2000 radiative facilities that use radiation sources in their processes and are controlled by The Brazilian Nuclear Energy Commission - CNEN through standards, authorizations and inspections. These radioactive materials, whether in the form of waste or radioactive source, used in medical, industrial, research, etc. are sometimes discarded and found in inappropriate places, such as garbage dumps, industrial waste, streets, squares, etc. found by urban cleaning professionals without the proper knowledge of them. The work presents the radiation protection actions required for the safe collection of radioactive material to be performed by these professionals. According to the type of radioactive material the main actions of radiation protection are, among others: recognition of a radioactive material; correct use of personal protective equipment to contain possible radiation contamination; implementation of an area control etc. In order for the actions of recognition and collection of discarded radioactive material to be effective, there is a need to implement a training program in radiation protection for urban cleaning professionals.

Hegazy, E.A.; AbdEl-Rehim, H

2008-01-01

Radiation induced degradation technology is a new and promising application of ionizing radiation to develop viscose, pulp, paper, food preservation, pharmaceutical production, and natural bioactive agents industries. Controlling the degree of degradation, uniform molecular weight distribution, saving achieved in the chemicals (used in conventional methods) on a cost basis, and environmentally friendly process are the beneficial effects of using radiation technology in these industries. However, for some development countries such technology is not economic. Therefore, a great effort should be done to reduce the cost required for such technologies. One of the principle factors for reducing the cost is achieving the degradation at low irradiation doses. The addition of some additives such as potassium per-sulfate (KPS), ammonium per-sulfate (APS), or H 2O2 to natural polymers such as chitosan and Na-alginate during irradiation process accelerates their degradation. The highest degradation rate of polysaccharides obtained when APS was used. The end product of irradiated chitosan, and Na-alginate may be used as food additive or benefited in agricultural purposes. The prepared crosslinked copolymers possessed high and fast swelling properties in simulated urine media and the swelling ratios of CMC-Na /PAAm gels in urine are acceptable for diaper application.

Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry

International Nuclear Information System (INIS)

2010-01-01

The oil and gas industry, a global industry operating in many Member States, makes extensive use of radiation generators and sealed and unsealed radioactive sources, some of which are potentially dangerous to human health and the environment if not properly controlled. In addition, significant quantities of naturally occurring radioactive material (NORM) originating from the reservoir rock are encountered during production, maintenance and decommissioning. The oil and gas industry operates in all climates and environments, including the most arduous conditions, and is continuously challenged to achieve high efficiency of operation while maintaining a high standard of safety and control - this includes the need to maintain control over occupational exposures to radiation, as well as to protect the public and the environment through proper management of wastes that may be radiologically and chemically hazardous. The oil and gas industry is organizationally and technically complex, and relies heavily on specialized service and supply companies to provide the necessary equipment and expertise, including expertise in radiation safety. This training manual is used by the IAEA as the basis for delivering its training course on radiation protection and the management of radioactive waste in the oil and gas industry. Enclosed with this manual is a CD-ROM that contains the presentational material used in the training course, the course syllabus and additional notes for course presenters. The course material is based principally on IAEA Safety Reports Series No. 34 Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry, published by the IAEA in 2003. The training course is aimed at regulatory bodies; oil and gas field operators and support companies; workers and their representatives; health, safety and environmental professionals; and health and safety training officers. A pilot training course was held in the Syrian Arab Republic in 2000 as

Conceptual model for decision support in mining industry NORM - aspects of environmental radiation protection

International Nuclear Information System (INIS)

Reis, Rocio Gloria dos

2012-01-01

Mining like many other industries can cause environmental impact. One of aspects that is in focus in many countries concerns to quantify the impact and establish requirements or improve the existing regulation about naturally occurring radioactive material - NORM. By a suitable management of the activities in these industries, there is an effort to minimize the waste production, minimize the environmental impacts and, consequently, the exposure of members of the public and workers. This study developed a conceptual model, a tool to assist in the decision making process for managers of mining and industrial facilities that deal with NORM. To develop this model, the Brazilian regulations were confronted with the regulations of countries where the NORM subject is important and with those that are being established by the principal institutions of radioprotection. The need of updating the Brazilian regulations was observed. Some recurring themes that are relevant to the management of NORM industries were surveyed, which resulted in the insertion of non-human biota risk assessment and the participation of stakeholders in the proposed model. The model was applied to a real case, the phosphoric acid and uranium plant of Santa Quiteria, in the Ceara state, with the aim of identifying the main critical points of the facility from the perspective of the environmental radiological impact and evaluating the adequacy of model, in addition to providing subsidies for its improvement. By the assessment of the process, it was found that the main source would be the phosphogypsum stack, which "2"2"6Ra activity concentration might exceed the level established for its use in agriculture and cement industry. The impact assessment was carried out in three different scenarios: 1) the critical group located in the facility borders, 2) the critical group located on the stack, after the closure of the area and 3) workers. In all cases, the exercise pointed out the exceeding of the adopted

When the ionizing radiation interact with the matter different effects happen on the radiations and on the matter. Many of these effects have been used with very different ends giving place to applications in several fields, among those that stand out the applications in medicine and industry. Basically, two different dispositions exist: one in that the radiation crosses or retrodisperse in the material and another in that the radiation acts on and it modifies the material.

Since the International Commission on Radiation Protection (ICRP) recommendation 60, the optimisation principle appears to be the core of the radiation protection system. In practice applying it, means implementing an approach both predictive and evolutionary - that relies essentially on a prudent and responsible state of mind. the formal expression of this process, called optimization procedure, implies and indispensable tool for its implementation: the system of monetary values for the unit of collective dose. During the last few years, feed ALARA principle means that a global work management approach must be adopted, considering together all factors contributing to radiation dose. In the nuclear field, the ALARA approach appears to be more successful when implemented in the framework of a managerial approach through structure ALARA programmes. Outside the nuclear industry it is necessary to clearly define priorities through generic optimisation studies and ALARA audits. At the international level much efforts remain to be done to expand efficiently the ALARA process to internal exposure as well as to public exposure. (author) 2 graphs, 5 figs., 3 tabs.

Radiation induced degradation technology is a new and promising application of ionizing radiation to develop viscose, pulp, paper, food preservation, pharmaceutical production, and natural bioactive agents industries. Controlling the degree of degradation, uniform molecular weight distribution, saving achieved in the chemicals (used in conventional methods) on a cost basis, and environmentally friendly process are the beneficial effects of using radiation technology in these industries. However, for some development countries such technology is not economic. Therefore, a great efforts should be done to reduce the cost required for such technologies. One of the principle factors for reducing the cost is achieving the degradation at low irradiation doses. The addition of some additives such as potassium per-sulfate (KPS), ammonium per-sulfate (APS), or H 2 O 2 to natural polymers (carboxymethylcellulose (CMC), chitosan, carrageenan and Na-alginate) during irradiation process accelerates their degradation. The highest degradation rate of polysaccharides obtained when APS was used. The end product of irradiated CMC, chitosan, carrageenan and Na-alginate may be used as food additive or benefited in agricultural purposes. On the other hand, radiation crosslinking of PAAm or PNIPAAm is affected by the presence of natural polymer like CMC-Na and carrageenan due to their degradability which could be controlled according to its concentration in the bulk medium and irradiation dose. Accordingly, the gel content, thermo-sensitivity (LCST) and swelling properties of PNIPAAm based natural polymers could be controlled. The swelling of the prepared copolymer hydrogels was investigated for its possible use in personal care articles particularly diapers or as carriers for drug delivery systems. The prepared crosslinked copolymers possessed high and fast swelling properties in simulated urine media and the swelling ratios of CMC-Na/PAAm gels in urine are acceptable for diaper

1995-01-01

A set of radiation overexposure event reports were reviewed as part of a program to examine human performance in industrial radiography for the US Nuclear Regulatory Commission. Incident records for a seven year period were retrieved from an event database. Ninety-five exposure events were initially categorized and sorted for further analysis. Descriptive models were applied to a subset of severe overexposure events. Modeling included: (1) operational sequence tables to outline the key human actions and interactions with equipment, (2) human reliability event trees, (3) an application of an information processing failures model, and (4) an extrapolated use of the error influences and effects diagram. Results of the modeling analyses provided insights into the industrial radiography task and suggested areas for further action and study to decrease overexposures

Growing international concern about radioactive sources after the Sept. 11, 2001 event has led to a strengthening of physical safety. There is evidence that the illicit use of radioactive sources is a real possibility and may result in harmful radiological consequences for the population and the environment. In Brazil there are about 2000 medical, industrial and research facilities with radioactive sources, of which 400 are Category 1 and 2 classified by the - International Atomic Energy Agency - AIEA, where large irradiators occupy a prominent position due to the very high cobalt-60 activities. The radiological safety is well established in these facilities, due to the intense work of the authorities in the Country. In the paper the main aspects on radiological and physical safety applied in the large radiators are presented, in order to integrate both concepts for the benefit of the safety as a whole. The research showed that the items related to radiation safety are well defined, for example, the tests on the access control devices to the irradiation room. On the other hand, items related to physical security, such as effective control of access to the company, use of safety cameras throughout the company, are not yet fully incorporated. Integration of radiation and physical safety is fundamental for total safety. The elaboration of a Brazilian regulation on the subject is of extreme importance

The Brazilian sugarcane industry constitutes one of the biggest and most efficient ethanol production processes in the world. Brazilian ethanol production utilizes a unique process, which includes cell recycling, acid wash, and non-aseptic conditions. Process characteristics, such as extensive CO 2 generation, poor quality of raw materials, and frequent contaminations, all lead to excessive foam formation during fermentations, which is treated with antifoam agents (AFA). In this study, we have investigated the impact of industrial AFA treatments on the physiology and transcriptome of the industrial ethanol strain Saccharomyces cerevisiae CAT-1. The investigated AFA included industrially used AFA acquired from Brazilian ethanol plants and commercially available AFA commonly used in the fermentation literature. In batch fermentations, it was shown that industrial AFA compromised growth rates and glucose uptake rates, while commercial AFA had no effect in concentrations relevant for defoaming purposes. Industrial AFA were further tested in laboratory scale simulations of the Brazilian ethanol production process and proved to decrease cell viability compared to the control, and the effects were intensified with increasing AFA concentrations and exposure time. Transcriptome analysis showed that AFA treatments induced additional stress responses in yeast cells compared to the control, shown by an up-regulation of stress-specific genes and a down-regulation of lipid biosynthesis, especially ergosterol. By documenting the detrimental effects associated with chemical AFA, we highlight the importance of developing innocuous systems for foam control in industrial fermentation processes.

2001-01-01

Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

Assessing land availability to produce biomass for energy: The case of Brazilian charcoal for steel making

Piketty, Marie-Gabrielle; Wichert, Marcos; Fallot, Abigail; Aimola, Luis

2009-01-01

The paper discusses the availability of biomass in Brazil to supply charcoal to the steel industry on the bases of an initial global assessment of land potentially available for plantations and of Brazilian data that allows refining the assessment and specifying the issue of practical availability. Technical potentials are first assessed through a series of simple rules against direct competition with agriculture, forests and protected areas, and of quantitative criteria, whether geo-climatic (rainfall), demographic (population density) or legal (reserves). Institutional, social and economic factors are then identified and discussed so as to account for the practical availability of Brazilian biomass through six criteria. The ranking of nine Brazilian States according to these criteria brings out the necessary trade-offs in the selection of land for plantations that would efficiently supply charcoal to the steel industry.

Industrial radiography is the process of using either gamma-emitting radionuclide sources or X-ray machines to examine the safety of industrial materials. The average annual effective dose in industrial radiography is one of the highest among radiation workers. The aim of this study was to investigate the cytogenetic effects of ionizing radiation in the peripheral blood lymphocytes of 60 industrial radiographers and 40 non-exposed individuals as the control group by using cytokinesis-block micronucleus (CBMN) assay. Totally, the frequencies of micronuclei (MN), nucleoplasmic bridges (NPBs) and nuclear buds (NBUDs) were significantly higher in the industrial radiographers than in the controls (p = 0.000). The mean MN frequency per 1000 binucleated cells in the industrial radiographers with last 5-y radiation dose of >100 mSv was significantly higher than those with ≤100 mSv (34.81 ± 12.70 vs. 26.33 ± 7.940, p = 0.024). The effect of age was observed in the control group and subjects with the age of >30 y showed significantly higher MN frequency compared with the subjects with the age of ≤30 y (9.45 ± 3.710 vs. 6.81 ± 3.050, p = 0.02). No obvious trend of increased MN as a function of either duration of employment or age or smoking status was observed in the industrial radiographers. The results show the increased levels of cytogenetic damages in the industrial radiographers. Even the workers exposed to the permissible doses are subjected to elevated frequencies of DNA damages. These findings confirm the importance of cytogenetic bio-monitoring program beside physical dosimetry, surveying radiation safety of equipment and periodic training of workers for improvement of safety and radiation protection.

On May 2000, an industrial gamma radiography operator, during a maintenance work of a 60 Co irradiator, has suffered a radiological accident with severe consequences to the left hand. The experts of the High Doses Analysis Group (GADE/IRD/CNEN) initiated the reconstructive dosimetry for the radiation dose estimation, in order to determine the real dose received by the operator, and to help the medical evaluation for prescribing the medical procedures for treatment of the involved victim. This paper presents the reconstructive dosimetry performed through the determination of the radiation doses of the operator, based on theoretical, experimental and computational methods. For the computer methods, a program for the calculation of external doses were used, based on the Monte Carlo method, and a human body simulator composed by voxels. The values of effective and equivalent doses are also presented which has caused severe lesions on the operator hand

To investigate if the levels of optical radiation hazards in glassblowing are well classified according to the hazard types defined in the Canadian Standards Association (CSA) standard for industrial eye protectors. We carried out radiometric measurements, and questionnaire survey in 4 university glassblowing laboratories, and 3 private studios. There is exposure to low levels of UV and IR radiation in all glassblowing operations. A supra-threshold IR radiation level exists in the craft glassblowing. The use of eye protectors is based on past experience regardless of the level of ocular exposure. Optical radiation hazards exist in both craft and scientific glassblowing. There seems to be an inadequate understanding about radiation types encountered by glassblowers.

Use of EMW radiation in the building industry at defects in buildings

Directory of Open Access Journals (Sweden)

Sobotka Jindřich

2017-01-01

Full Text Available This paper discusses theory and application of microwave radiation and experimental optimization of microwave radiation to eliminate moisture content in wood elements. It will be appreciated that the rising moisture leaking into the structure, resulting in defects and structures of the buildings themselves. Owing to its properties, microwave radiation has been used in the construction industry in modern times, in particular to dry wet masonry of buildings. Effects of electromagnetic radiation on building structures lead to relatively sharp decreases in moisture content from damp building structures or elements. The influence of electromagnetic radiation on building structures lead to oscillation of water molecules contained in the material, which cause a phase transformation of water into vapour. Consequently, the vapour evaporates from the moist material, thereby drying the element exposed to radiation. The article describes experiments carried out at the Faculty of Civil Engineering of the Faculty of Technology in Brno that demonstrate successful decrease of water content in building materials using microwave radiation. First, the understanding of microwave radiation will be discussed. Following an analysis of research results an optimum intensity of microwave radiation sources as well as the necessary length of the irradiation of microwave radiation have been determined with respect to the particular type of building material and the success rate of elimination of moisture.

Radiological protection, safety and security issues in the industrial and medical applications of radiation sources

International Nuclear Information System (INIS)

Vaz, Pedro

2015-01-01

The use of radiation sources, namely radioactive sealed or unsealed sources and particle accelerators and beams is ubiquitous in the industrial and medical applications of ionizing radiation. Besides radiological protection of the workers, members of the public and patients in routine situations, the use of radiation sources involves several aspects associated to the mitigation of radiological or nuclear accidents and associated emergency situations. On the other hand, during the last decade security issues became burning issues due to the potential malevolent uses of radioactive sources for the perpetration of terrorist acts using RDD (Radiological Dispersal Devices), RED (Radiation Exposure Devices) or IND (Improvised Nuclear Devices). A stringent set of international legally and non-legally binding instruments, regulations, conventions and treaties regulate nowadays the use of radioactive sources. In this paper, a review of the radiological protection issues associated to the use of radiation sources in the industrial and medical applications of ionizing radiation is performed. The associated radiation safety issues and the prevention and mitigation of incidents and accidents are discussed. A comprehensive discussion of the security issues associated to the global use of radiation sources for the aforementioned applications and the inherent radiation detection requirements will be presented. Scientific, technical, legal, ethical, socio-economic issues are put forward and discussed. - Highlights: • The hazards associated to the use of radioactive sources must be taken into account. • Security issues are of paramount importance in the use of radioactive sources. • Radiation sources can be used to perpetrate terrorist acts (RDDs, INDs, REDs). • DSRS and orphan sources trigger radiological protection, safety and security concerns. • Regulatory control, from cradle to grave, of radioactive sources is mandatory.

Queiroz, Paulo Cesar Beltrao de; Zouain, Desiree Moraes

2009-01-01

This paper analyzes both the carbon fiber-based development for uranium centrifuges and the research project that supports its development effort over time. The carbon fiber-based engineering properties make it a valuable supply for high technologic products. Nevertheless, its fabrication occurs only in few developed countries and there is no production in Brazil. In addition, the carbon fiber-based products have dual applications: they can be used by the civilian and military industry. Therefore, there are international restrictions related to its use and applications that justify the internal development. Moreover, the Brazilian Navy centrifuges for uranium enrichment were developed using carbon-fiber which contains polyacrylonitrile (PAN) as an imported raw material. The PAN properties of low weight, high tensile strength increase the isotopic separation efficiency. The Brazilian financial scenario surrounded by the international uncertain economy shows that combined creative project solutions are more effective. Therefore, the Navy's Technological Center in Sao Paulo (CTMSP), the University of Campinas (UNICAMP), the University of Sao Paulo (USP), the RADICIFIBRAS Company, and the Brazilian FINEP agency, which is responsible for the project financial support, established a partnership aiming the development of a domestic PAN-based carbon fiber industry. The innovative project solutions adopted and the results of this partnership are presented here. (author)

Estimativa do balanço de radiação por sensoriamento remoto de diferentes usos de solo no sudoeste da Amazônia brasileira / Estimative of radiation balance by remote sensing of different soil uses in the brazilian southern Amazon

Directory of Open Access Journals (Sweden)

Luiz Carlos Da Silva

2015-08-01

Full Text Available Changes in land use have motivated research on the dynamics of radiative and energy exchange in the Brazilian Amazon, which in turn cause demand for such data on the surface in spatial and temporal scales. While measuring these changes in micrometeorological towers provides punctual results, remote sensing provides accurate and low cost results to estimate them on a regional scale. This study aimed to evaluate the spatial and temporal distribution of estimates of net radiation and biophysical parameters from remote sensing in different land uses in southwestern Brazilian Amazon. Four sites were selected with soil covers by natural Amazon forest, Amazon managed forest, pasture and silvopastoral system. The net radiation and biophysical parameters (NDVI, leaf area index, albedo and radiometric temperature were estimated by the SEBAL algorithm, using images from the Landsat TM sensor 5 in July of 2009, 2010 and 2011. The NDVI, LAI, albedo and net radiation were higher in natural forest, followed by managed forest, grassland and silvopastoral system. Radiometric surface temperature were higher in the silvopastoral system followed by pasture, natural forest and managed forest.

Attribution of CO2 emissions from Brazilian deforestation to consumers between 1990 and 2010

Karstensen, Jonas; Peters, Glen P; Andrew, Robbie M

2013-01-01

Efforts to reduce deforestation to mitigate climate change and to conserve biodiversity are taking place on a global scale. While many studies have estimated the emissions occurring from deforestation, few studies have quantified the domestic and international drivers sustaining deforestation rates. In this study we establish the link between Brazilian deforestation and production of cattle and soybeans, and allocate emissions between 1990 and 2010 along the global supply chain to the countries that consume products dependent on Brazilian deforestation. We find that 30% of the carbon emissions associated with deforestation were exported from Brazil in the last decade, of which 29% were due to soybean production and 71% cattle ranching. The share exported is growing, with industrialized nations and emerging markets (especially Russia and China) greatly increasing imports. We find a correlation between exports (and hence global consumption) of Brazilian cattle and soybeans and emissions from deforestation. We conclude that trade is emerging as a key driver of deforestation in Brazil, and this may indirectly contribute to loss of the forests that industrialized countries are seeking to protect through international agreements.

Gamma radiation effect on agar viscosity for use in food industry

International Nuclear Information System (INIS)

Aliste, Antonio J.; Del Mastro, Nelida L.

1999-01-01

The application of food radiation processing is increasing worldwide mainly because of its efficiency in the industrial decontamination of packaged food products. Indeed, the process neither introduces any undesirable elements nor increases the temperature, thus allowing the preparation of ready-to-use products which remain stable for long periods at room temperature. The aim of this work was to study the effect of Co-60 gamma radiation on the viscosity of agar. This hydrocolloid derived from seaweed is a galactose polymer with a high hysteresis capacity (great difference among melting and gelification temperature) which is extremely important when used as additive for the food industry. Commercial agar was irradiated with doses of 0, 1, 5 and 10 kGy. Proper dilutions were prepared and the viscosity was measured in a Brookfield model LVDVIII viscosimeters. The relationships viscosity/dose for the temperatures of 45 deg C and 60 deg C were established. The decrease of the viscosity was 71.4% and 49.6% respectively when the applied dose was 10 kGy. The implications of the use of this additive in food irradiation are discussed. (author)

Full Text Available This paper deals with the potential for internationalization of the Brazilian software industry from the perspective of software developers and service providers. The purpose of the study conducted was to better understand the way Brazilian software companies relate to the international software market by comparing the perceptions of entrepreneurs and those of government agency officials responsible for increasing Brazil's participation in the international software market. Data collection took place by means of semi-structured interviews with entrepreneurs and government agency officials. The data gathered was subjected to content analysis. Results show that Brazilian software companies perform poorly with regard to levels of exporting their products and services for a number of reasons, among which the most outstanding is that they still think that the internal market offers enough challenges and opportunities.

Alternative fuels: a Brazilian outlook

International Nuclear Information System (INIS)

Moreira, J.R.; Serra, G.E.

1990-01-01

This paper focuses on studies and information related to the use of alternative fuels in Brazil. The first part of this paper deals with the economics of different biomass technologies. The analysis consists of a careful costing of all operations involved. The study deals with wood, sugar cane and cassava, since these crops are exploited for commercial purposes in Brazil. Corn, although a useful raw material for producing ethanol in the United States, is not used for this purpose in Brazil. The second part deals with the industrial technologies used to convert biomass into energy. We consider several forms of energy derived from biomass and evaluate the economics of the processes. When opportune, we compare costs with those of the North American market. Market analysis and displacement of conventional energy are the subject of the third part of the paper. While the cost of each product is evaluated in most cases; in others the current market price is used. Finally, we raise the issues of institutional problems and planning and offer some conclusions on the future of biomass as an alternative energy source. The technological discussion in this paper is based on the Brazilian experience in producing ethanol and other fuels from biomass. It is possible to extrapolate the Brazilian experience to other developing countries. The observations made in this chapter are based on the conditions prevalent in the Brazilian south-central agricultural region, specifically the state of Sao Paulo.

Radiological assessment of NORM industries in Ireland-radiation doses to workers and members of the public

International Nuclear Information System (INIS)

Organo, C.; Fenton, D.

2008-12-01

Natural resources that are extracted from the ground such as coal, oil, natural gas and other mineral ores contain various amounts of natural radioactivity. When these resources are extracted and processed, their natural state can be modified which may result in the enhancement of the natural radioactivity content originally present. Such enhancements may be observed in the residues or the waste created and/or in the products or by-products and are sometimes high enough to pose a risk to both humans and the environment if they are not controlled properly. Materials of this kind are commonly referred to as Naturally Occurring Radioactive Materials or NORM. Up to 1996, international regulatory attention dealing with exposure to natural sources of radiation focused mostly on exposures arising from the mining and processing of uranium ores because such activities need to be controlled as part of the nuclear fuel cycle. More recently, the attention of the international radiation protection community has been broadened to include industries dealing with NORM. The most recent revision of the European Basic Safety Standards (BSS) Directive took place in 1996 and includes special provisions concerning exposure to natural sources of ionising radiation. The implementation of the 1996 European Directive resulted in significant legal changes in Ireland. Previously the national radiation protection regulations did not cover work activities involving exposure to natural sources. This changed on 13th May 2000 and according to current Irish regulations, work activities involving exposure to natural sources of radiation such as NORM are amenable to control if they are liable to give rise to an effective dose to workers or members of the public in excess of 1 mSv above background in any 12-month period. To assist Member States in the implementation of the 1996 European Directive with regards to the provisions dealing with natural sources of radiation, recommendations on how to target

Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry. Additional Information

International Nuclear Information System (INIS)

2010-01-01

The oil and gas industry, a global industry operating in many Member States, makes extensive use of radiation generators and sealed and unsealed radioactive sources, some of which are potentially dangerous to human health and the environment if not properly controlled. In addition, significant quantities of naturally occurring radioactive material (NORM) originating from the reservoir rock are encountered during production, maintenance and decommissioning. The oil and gas industry operates in all climates and environments, including the most arduous conditions, and is continuously challenged to achieve high efficiency of operation while maintaining a high standard of safety and control - this includes the need to maintain control over occupational exposures to radiation, as well as to protect the public and the environment through proper management of wastes that may be radiologically and chemically hazardous. The oil and gas industry is organizationally and technically complex, and relies heavily on specialized service and supply companies to provide the necessary equipment and expertise, including expertise in radiation safety. This training manual is used by the IAEA as the basis for delivering its training course on radiation protection and the management of radioactive waste in the oil and gas industry. Enclosed with this manual is a CD-ROM that contains the presentational material used in the training course, the course syllabus and additional notes for course presenters. The course material is based principally on IAEA Safety Reports Series No. 34 Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry, published by the IAEA in 2003. The training course is aimed at regulatory bodies; oil and gas field operators and support companies; workers and their representatives; health, safety and environmental professionals; and health and safety training officers. A pilot training course was held in the Syrian Arab Republic in 2000 as

Planned and projected budget cuts over the next many years will reduce the number of Department of Defense (DoD) personnel and the diversity and quantity of their armaments and systems. Consequently, there is a requirement for the deployment of more effective defense equipment and their more efficient operation. Concomitant with this challenge is an opportunity for innovative technologies that can, at a lower cost, produce new, stronger, more durable materials-and do so with less environmental impact. Radiation processing offers this potential for (a) creating significant cost savings and performance advantages in a broad range of defense materials; (b) destroying and detoxifying dangerous chemicals, ordnance, and rocket propellants; (c) cleaning noxious gaseous effluents; and (d) purifying contaminated water. Radiation technology has the potential to immediately affect defense materials and, in the short and long terms, US industrial international competitiveness

Federal Legislation in Brazil establishes that the Brazilian Nuclear Energy Commission - CNEN - is responsible for the surveillance of the industrialization of nuclear ores and the production and commerce of nuclear materials in such way that activities such as buying, selling, import and export, are subject to previous licensing and surveillance. Regulation CNEN-NN-4.01 on Safety and Radiation Protection in Mining and Milling Facilities of conventional ores containing naturally occurring radioactive materials, NORM, was issued in 2004 establishing both a methodology for classification of these facilities into three Categories, taking into account both the contents of uranium and thorium in the ores and the applicable radiation and safety requirements based on a graded approach. Although the lack of a licensing process in the above mentioned Regulation made its implementation a difficult task, CNEN, by means of an initial survey, identified ca. 30 mining and milling industries of conventional ores containing uranium and thorium with concentrations above 10 Bq/g. More recently, a new juridical understanding of the legislation concluded that CNEN must issue licences and authorizations for the possession and storage of all ores with uranium and thorium concentrations above exemption levels. A proper surveillance programme encompassing 13 of these mining facilities was then put forward aiming at the improvement of their safety and radiation protection. This article presents an overview of NORM exploitation in Brazil and put forward suggestions for achieving viable solutions for the protection of workers, general public and environment from the effects of ionizing radiation.

Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

Science.gov (United States)

Meneghini, R

2010-09-01

Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

Estimation of annual radiation dose received by some industrial workers

International Nuclear Information System (INIS)

Garg, Ajay; Chauhan, R.P.; Kumar, Sushil

2013-01-01

Radon and its progeny in the atmosphere, soil, ground water, oil and gas deposits contributes the largest fraction of the natural radiation dose to populations, enhanced interest exhibited in tracking its concentration is thus fundamental for radiation protection. The combustion of coal in various industrial units like thermal power plants. National fertilizer plants, paper mill etc. results in the release of some natural radioactivity to the atmosphere through formation of fly ash and bottom ash or slag. This consequent increases the radioactivity in soil, water and atmosphere around thermal power plants. Keeping this in mind the measurements of radon, thoron and their progeny concentration in the environment of some industrial units has been carried out using solid state nuclear track detectors (SSNTD). The specially designed twin cup dosimeter used here consists two chambers of cylindrical geometry separated by a wall in the middle with each having length of 4.5 cm and radius of 3.1 cm. This dosimeter employs three SSNTDs out of which two detectors were placed in each chamber and a third one was placed on the outer surface of the dosimeter. One chamber is fitted with glass fiber filter so that radon and thoron both can diffuse into the chamber while in other chamber, a semi permeable membrane is used. The membrane mode measures the radon concentration alone as it can diffuse through the membrane but suppresses the thoron. The twin cup dosimeter also has a provision for bare mode enabling it to register tracks due to radon, thoron and their progeny in total. Therefore, using this dosimeter we can measure the individual concentration of radon, thoron, and their progeny at the same time. The annual effective doses received by the workers in some industrial units has been calculated. The results indicate some higher levels in coal handling and fly ash area of the plants. (author)

Reconstructive dosimetry and radiation doses evaluation of members of the public due to radiological accident in industrial radiography

Lima, Camila Moreira Araujo de

2016-01-01

Radiological accidents have occurred mainly in the practices recognized as high risk radiological and classified by the IAEA as Categories 1 and 2, and highlighted the radiotherapy, industrial irradiators and industrial radiography. In Brazil, since there were five major cases in industrial radiography, which involved 7 radiation workers and 19 members of the public, causing localized radiation lesions on the hands and fingers. One of these accidents will be the focus of this work. In this accident, a "1"9"2Ir radioactive source was exposed for more than 8 hours in the workplace inside a company, exposing radiation workers, individuals of the public and people from the surrounding facilities, including children of a school. The radioactive source was also handled by a security worker causing severe radiation injuries in the hand and fingers. In this paper, the most relevant and used techniques of reconstructive dosimetry internationally are presented. To estimate the radiation doses received by exposed individuals in various scenarios of radiological accident in focus, the following computer codes were used: Visual Monte Carlo Dose Calculation (VMC), Virtual Environment for Radiological and Nuclear Accidents Simulation (AVSAR) and RADPRO Calculator. Through these codes some radiation doses were estimated, such as, 33.90 Gy in security worker's finger, 4.47 mSv in children in the school and 55 to 160 mSv for workers in the company during the whole day work. It is intended that this work will contribute to the improvement of dose reconstruction methodology for radiological accidents, having then more realist radiation doses. (author)

Natural gas perspectives of diffusion on the brazilian structural ceramics industry; Perspectivas de difusao do gas natural na industria brasileira de ceramica vermelha

Energy Technology Data Exchange (ETDEWEB)

Schwob, Marcelo Rousseau Valenca

2007-03-15

This study evaluates the perspectives of the natural gas (NG) used by the Brazilian structural ceramics industry (BSCI), according to technological, economic and environmental aspects. It identifies the advantages of using NG, as well as the barriers faced by this energy source. Considering the amount of NG required by the thermal demand of the BSCI processes and the average energy specific use of the furnaces in operation in Brazil, the total consumption of NG will be nearly 12.06 Mm{sup 3/}day. However, the existence of few technical and economical adequate conversion conditions for ceramics furnaces (4% of continuous furnaces) limits the previous potential to only 0.67 Mm{sup 3/}day. In addition, considering the geographic intersection of the ceramics production clusters with the natural gas distribution grid of the Brazilian states, the estimated potential is lowered to 0.28 Mm{sup 3/}day. Yet, the perspective of the NG diffusion in the BSCI in the medium to the long term is more positive, owning to the increasing implementation of large scale production furnaces and cogeneration systems. Also worthwhile to this positive perspective are: the improving demand for certified structural ceramic products, with more quality and value added, and the expanding investment in low income classes dwelling programs.

Utilization of radiation in the industrial field has been enlarged due to the variety of technologies. In the present paper, the economic scale between the U.S.A. and Japan is compared with selected industrial parameters such as sterilization, semiconductors, radiographic testing (RT) and radial tire production because the very large industrial markets make a whole comparison difficult. The economic scale revealed was about 56b$ (1$=121 yen) for the U.S.A. and 39b$ for Japan. The former is large in magnitude by a factor of 1.4. With respect to the relative ratio versus the GDP, the former was 0.7% and 0.9% for the latter. This implied that utilization of radiation in industry is large in magnitude and is expected to be further developed. Regarding electron beam (EB) accelerators, for example, 648 units were installed in North America and 308 units for Japan during the past 29 years. The large number of the former is attributed to use in curing and heat shrinkable tubes (film). (author)

Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

Industry's demand for the BESSY synchrotron radiation (SR): approaches towards interlinking basic scientific research activities and industry

In Germany, industry's demand for synchrotron radiation (SR) is very limited, due to the current macroeconomic situation and the corporate strategy of potential SR users in industry. This is in contrast to the conditions in the USA (and Japan), where industrial enterprises more readily invest in and run their own long-term basic research projects for exploration of potential commercial applications according to their demands, with research goals pursued there and in Germany overlapping to a large extent. It cannot be expected that demand for SR from industry in Germany will ever come up to the level seen in the USA. In Germany, non-university research institutes are most likely to become an important group of potential users of SR. Substantially boosting the demand for SR from industry will need a change of macroeconomic framework conditions affecting the corporate strategy to the effect that industry will more strongly commit itself to and take up responsibility for application-oriented fundamental research and the corresponding technology transfer. This can be achieved by a policy providing both for institutional means and financial incentives. As to near-market, strategic technological developments, establishment of structures allowing direct cooperation of science and technology, for instance in the form of joint ventures, or underwriting agreements and corresponding supervisory boards, seem to be promising. As to basic-research-oriented promotion of research, a technology screening might lead to the selection of technology-relevant research goals, and corresponding financial support from a special fund. Such incentives for cooperative action by technology, science and the government will create novel types of research-industry interfaces in Germany between ''historical'' spheres of autonomy of research of industry and the scientific community.

Due to the construction, by Brazilian Navy, of a Submarine Construction and Maintenance Ship with Nuclear Propulsion, where, among other activities, the commissioning and exchange of the fuel elements of the reactor in the future Nuclear Submarine, and of a Naval Base where the Nuclear Submarine and the Conventional Submarines, it is necessary the establishment of a Nuclear Security Naval Agency to monitor activities involving ionizing radiation sources and nuclear materials aimed at the radiological protection of exposed occupationally individuals (IOE), the general public and the environment. It should be noted that nuclear and radioactive material will be present only in a part of the yard called Radiological Complex. Therefore, the development of a structure for the control of the Radiological Complex is fundamental, considering that the future licensing process will be unprecedented in Brazil and will face several difficulties. This work presents a model of a structure for the radiological control of the industrial complex for the construction and maintenance of the submarine with nuclear propulsion, as well as the fundamental concepts of the activities, such as inspection, regulations and authorizations, to be carried out by the various component sectors of the Nuclear Security Naval Agency.

Propolis is a natural product from vegetable origin, but, this substance, in general, is collected in the beehives. This product is largely known because its heath benefit attributed to its biological properties. On the other hand, Brazilian sugarcane spirit, 'cachaca', is an interesting alcoholic beverage with an increasing importance in the segment in many markets in the world. Therefore, was evaluating the addition of the propolis into cachaca and the effect of ionizing radiation on propolis compounds with biological properties. Samples of cachaca with propolis used in irradiation experiments were prepared from cachaca (40 deg GL) composed with propolis (0.1%). Eight treatments, with four repetitions each, were considered in this study. Three doses of ionizing energy from electron beam and gamma radiation from 60 Co were applied on the cachaca samples, i.e. 0.5, 1.0, and 2.0 kGy, with the goal to accelerate the aging time of the cachaca. The sugarcane spirits samples were storage during two periods (immediately after the radiation treatment and 30 months after the treatments) and their flavonoids contents were analyzed. Flavonoids contents in sugarcane spirit were statistically different between both storage time. The samples of cachaca treated with electron beam at 2.0 kGy presented the highest reduction in flavonoids contents, approximately 30.0 % in relation to the first analysis time. In conclusion, the time of storage to promote reduction on the flavonoids contents and the ionizing radiation also promoted reduction on the contents of these compounds, mainly in the first period of storage.

The most important applications of the radiation technology are the crosslinking of polymers and sterilisation. Although extensive experience about the use of this technology is available and powerful and dependable radiation facilities can be obtained, as yet the radiation technology has not found the acceptance it deserves in the industry. The main reason therefore has to do with how the question of radiation or the term radiation is presented to the industry and among the population. This paper will deal with considerations and ways in which the industrial use of the radiation technology can be expanded. (author)

Smoking or health: the Brazilian option.

Lokschin, F; Barros, F C

Tobacco plays a key role in both disease and the economy in Brazil. In 1981 about 135 billion cigarettes were smoked, and cigarette-related diseases far outnumber infections as the leading cause of death. Brazil is the 4th largest world producer and the 2nd largest exporter of tobacco. 2.1% of the total population -- 2.5 million people -- are maintained by tobacco-related activities. Cigarette sales taxes provide 11.6% of the country's total taxes. Involved in a deep economic crisis, Brazil depends on this revenue and has not introduced any measures to control or counteract the high pressure marketing of cigarette manufacturers. Ischemic heart disease is the leading cause of death in Brazil, taking 90,000 lives in 1979. Based on World Health Organization estimates, at least 25% of these deaths could be ascribed to smoking. Cancer is the 2nd largest cause of death. In 1979, 10% of 60,000 cancer deaths were from lung cancer. Based on estimate that 30% of cancer deaths are provoked by smoking, more than 20,000 of those deaths were caused by tobacco. In Brazil, lung cancer is the 2nd highest cause of death from cancer in men and 3rd among women. Smoking in Brazil is definitely associated with low birth weight, the single most important predictive factor of perinatal and infant mortality. Rural workers giving up subsistence crops to grow tobacco may also affect their children's health. Also in such low-income populations, expenditures for cigarettes leave less money for essential goods. As a result of the high tax rate and the enormous number of cigarettes sold, 11.6% of all the country's revenue comes from the tobacco industry. The Brazilian Association of Tobacco Industries has been trying to link cigarette sales to Brazilian social development but does not mention the cost of disease, disability, and early death provoked by smoking. In Brazil tobacco companies have a huge market free of constraints, and the country lacks consistent smoking control policies. Recently

Presently, ten industrial radiography facilities are operating in Bangladesh using X-ray or gamma-ray sources. During the last 5-year, 14 industrial radiography facilities were received individual monitoring service using thermoluminescent dosimeters (TLDs) from the Health Physics Division (HPD), Atomic Energy Centre, Dhaka under Bangladesh Atomic Energy Commission. HPD is the only individual monitoring service provider in Bangladesh due to external sources of ionizing radiation. The number of monitored industrial radiography facilities ranged from 7 to 14 while the number of worker ranged from 72 to 133 during the study period. The annual average effective doses received from external radiation in industrial radiography workers and the distributions of the annual effective doses by dose intervals are presented. The distribution of the occupational doses shows that the majority (about 75 %) of workers received doses below 1 mSv for the last 5-years. Even though, very few workers (about 1%) received doses higher than average annual dose limit (20 mSv), but no workers received doses higher than 100 mSv in 5 consecutive years. The average annual effective dose of industrial radiography workers in Bangladesh is higher than the corresponding values in Tanzania, Greece, Poland, Australia, UK and lower than in Bosnia and Herzegovina, USA and Canada. However, the average annual effective dose is comparable to the corresponding values in China, Brazil, Germany and India. The status and trends in occupational doses show that radiation protection situation at the majority of the workplace were satisfactory. In spite of that, additional measures are required due to big differences observed in the maximum individual doses over the last 5-year. (author)

The overall goal of NASA's SCAR (Smoke, Cloud and Radiation) Program is to obtain physical and chemical properties of the smoke produced by biomass burning and the effects of the smoke on the earth's radiation balance and climate. It is a joint project with the Brazilian government and their organizations, including INPE (Instituto Nacional Pesquisas Espaciais) who actively participate in all activities. Appropriate estimates of the biomass buming in the tropics is therefore essential to determine its effect on the atmosphere and on climate. The SCAR series of experiments is designed with that purpose. The present study of evaluating the burnt-out areas is to augment the data collected to date to help evaluate the effect of biomass burning.

Pharmaceutical and biotechnology industries comprise a major production subsystem of the health industrial complex in Brazil. It stands out for both its economic importance and its prominent role in developing new technologies in strategic areas. Strengthening the local production of generic drugs in the last decade has significantly increased the number of Brazilian companies in the local pharmaceutical market and has been an important turning point for this industry's growth. However, there remain major structural bottlenecks both in terms of production and continuous innovation. These bottlenecks reveal the high vulnerability of the Brazilian National Health System and point to the need of public policies that promote strengthening the production base and innovation in the pharmaceutical industry and that at the same time meet health-related social demands in health in Brazil.
