Environment report 1990 of the Federal Minister for the Environment, Nature Protection and Reactor Safety

International Nuclear Information System (INIS)

1990-01-01

The 'Environment Report 1990' describes the environmental situation in the Federal Republic of Germany; draws a balance of environmental policy measures taken and introduced; gives information on future fields of action in environmental policy. The 'Environment Report 1990' also deals with the 'Environment Expert Opinion 1987', produced by the board of experts on environmental questions. It contains surveys of the following sectors: Protection against hazardous materials air pollution abatement, water management, waste management, nature protection and preservation of the countryside, soil conservation, noise abatement, radiation protection, reactor safety. A separate part of the 'Environment Report 1990' deals with the progress made in 'interdisciplinary fields' (general law on the protection of the environment, instruments of environmental policy, environmental information and environmental research, transfrontier environmental policy).

The case against protecting the environment from ionising radiation

International Nuclear Information System (INIS)

Smith, J.T.

2004-01-01

The objective of this paper is to present the (rarely heard) argument in favour of retention of the present system of radiation protection of the environment. There has been a recent trend in the radioecological and radiation protection community towards greater regulation of the effects of ionising radiations on biota. In particular, the often quoted International Commission on Radiation Protection (ICRP) hypothesis that: If humans are protected from the effects of ionising radiation, then flora and fauna are also adequately protected has been criticised as being too anthropocentric and not adequate for protection of the environment. In this paper I will challenge this view, arguing firstly that this statement is almost always quoted out of its proper context, and secondly that the ICRP hypothesis does adequately protect the environment from the effects of ionising radiations. In view of the relatively insignificant effect of regulated releases of ionising radiation on the environment, the economic cost of further regulation will not result in a significant environmental benefit. Whilst empirical research to test the ICRP hypothesis should continue, until there is clear evidence against it, this simple and cost-effective approach should be retained. This would benefit the environment by directing scarce resources to more urgent environmental problems. (author)

Environment protection and other political spheres of the European Community

Rengeling, H.W.

1993-01-01

It has long been known that environment protection is largely a cross-sectional task. The provision of Article 130 r Section 2 Clause 2 of the EEC Treaty that states that environment protection forms an integral part of all the other polticial spheres of the Community is not only a plank in the platform of the Community but also a juridical innovation. Time will tell what concrete legal claims can be derived from this provision, particularly on the part of the European Court of Justice. The lectures relate amongst others to the following topics: Environment protection and competition politics, environment protection and energy poltics, environment protection and development aid politics. Eight of the lectures were abstracted individually. (orig./HSCH) [de

Protection of the natural environment and internationally accepted practice

1996-01-01

This paper reviews the present approach to protecting the environment against ionizing radiations in international standards and guidance. This approach is based on the assumption that protecting humans will provide adequate protection for the environment. The extent to which the assumption can and has been justified is examined. Possible reasons for wishing to reconsider or elaborate the approach and to develop specific criteria for protecting other species are discussed

PROTECTIVELY COVERED ARTICLE AND METHOD OF MANUFACTURE

Plott, R.F.

A method of casting a protective jacket about a ura nium fuel element that will bond completely to the uranium without the use of stringers or supports that would ordinarily produce gaps in the cast metal coating and bond is presented. Preformed endcaps of alumlnum alloyed with 13% silicon are placed on the ends of the uranium fuel element. These caps will support the fuel element when placed in a mold. The mold is kept at a ing alloy but below that of uranium so the cast metal jacket will fuse with the endcaps forming a complete covering and bond to the fuel element, which would otherwise oxidize at the gaps or discontinuities lefi in the coating by previous casting methods.

Vegetation Cover and Furrow Erosion due to Extreme Rain Events in Semiarid Environments

Directory of Open Access Journals (Sweden)

Full Text Available The conservation of the soil resource in semi-arid environments is one of the major challenges of agricultural systems, particularly in the Mediterranean region. In the present study, two types of soil management were compared: minimum tillage (ML and minimum tillage with spontaneous vegetation cover (MLVE. The comparison was conducted in a rainfed almond plantation at slope (35%, under an extraordinary event in 2015 (91.3 mm and EI30 of 2,719.89 mm ha-1 h-1. In this situation in MLVE plots, the development of furrows in contrast to ML were not recorded; the total soil loss was more than 12 times lower than that recorded in the latter. This fact demonstrated the effectiveness of the vegetal cover in the protection of the agricultural soil against the erosion during extreme events. Also, for ML management, furrow erosion represented more than 60% of the total soil loss, demonstrating the dominance of this type of erosion. Finally, it should be noted that this event represents the almost total loss of soil recorded in the experimental plots during the period 2012-2015; and this consequently shows the significant impact of extreme events on erosion rates in the Mediterranean region.

Do we need radiation protection for the living environment?

International Nuclear Information System (INIS)

Hefner, A.; Voelkle, H.

2003-01-01

The protection of the living environment, i.e. non human species or non human organisms, is a condition for the long term human survival. This certainly is true also for radioactivity and ionizing radiation. The ICRP statement that fauna und flora are sufficiently protected if man is protected is valid in many cases but not in every one. The article gives some reflections on this subject from the point of view of practical radiation protection and some suggestions on how, if necessary, protection of the living environment could be put into practice.

2015-11-03

Decisions determining the use of land for energy are of exigent concern as land scarcity, the need for ecosystem services, and demands for energy generation have concomitantly increased globally. Utility-scale solar energy (USSE) [i.e., ≥ 1 megawatt (MW)] development requires large quantities of space and land; however, studies quantifying the effect of USSE on land cover change and protected areas are limited. We assessed siting impacts of >160 USSE installations by technology type [photovoltaic (PV) vs. concentrating solar power (CSP)], area (in square kilometers), and capacity (in MW) within the global solar hot spot of the state of California (United States). Additionally, we used the Carnegie Energy and Environmental Compatibility model, a multiple criteria model, to quantify each installation according to environmental and technical compatibility. Last, we evaluated installations according to their proximity to protected areas, including inventoried roadless areas, endangered and threatened species habitat, and federally protected areas. We found the plurality of USSE (6,995 MW) in California is sited in shrublands and scrublands, comprising 375 km(2) of land cover change. Twenty-eight percent of USSE installations are located in croplands and pastures, comprising 155 km(2) of change. Less than 15% of USSE installations are sited in "Compatible" areas. The majority of "Incompatible" USSE power plants are sited far from existing transmission infrastructure, and all USSE installations average at most 7 and 5 km from protected areas, for PV and CSP, respectively. Where energy, food, and conservation goals intersect, environmental compatibility can be achieved when resource opportunities, constraints, and trade-offs are integrated into siting decisions.

A common approach for radiological protection of humans and the environment

International Nuclear Information System (INIS)

Holm, L.-E.

2004-01-01

Protection of the environment is developing rapidly at the national and international level, but there are still no internationally agreed recommendations as to how radiological protection of the environment should be carried out. The International Commission on Radiological Protection (ICRP) is currently reviewing its existing recommendations for human protection. It has set up a task group with the aim of developing a protection policy for, and suggesting a framework of, the protection of the environment that could feed into its recommendations at the start of the 21st century. The task group will propose a framework for the protection of the environment from harmful effects of radiation, harmonising with the principles for the protection of humans. Although the task group has not yet finalised on the objectives for the environment, these might be to safeguard the environment by preventing or reducing the frequency of effects likely to cause early mortality, reduced reproductive success, or the occurrence of scorable DNA damage in individual fauna and flora to a level where they would have a negligible impact on conservation of species, maintenance of biodiversity, or the health and status of natural habitats or communities. To achieve these objectives, a set of reference dose models, reference dose per unit intake and reference organisms will be required

On the Radiation Protection of the Environment

International Nuclear Information System (INIS)

Soberhart, L. J.; Clausse, A.; D'Amato, E.

2004-01-01

Over the last decade, substantial advances in what is know as legal protection of the environment, -as a different matter from human being protection- have been made. Some national legislations include serious penalties against environmental damage. It is becoming customary to consider a serious offence any excess in the prescribed limits of radioactive materials release to the environment. What these limits mean, however, is not completely clear nowadays. According to the International Commission on Radiological Protection (ICRP) the standards of environmental control needed to protect man to the degree currently thought desirable will ensure that other species are not put at risk, although, occasionally, individual members of non human species might be harmed. However the use of limits of radioactive releases resulting from the direct application of ICRP recommend limits as legal references for the applicable offences in environmental protection is certainly a misconception. In this paper a conceptual framework for the calculation of legal limits for environmental radioprotection are presented. The approach is based on an ecosystem perspective, assessing the impact of radioactive releases on the ecosystem dynamics and equilibrium. The method is based on functional groups models -i.e. groups of species that are selected from a number of criteria such as play similar rules in the chain of nutrients or have the same radiosensitivity- providing the basis for prescribed limits of the radioactive material release to the environment. The methodology is applied to a system of three functional groups in equilibrium, with is affected by radioactive intrusion. Different impacts on the equilibrium can be identified, depending on the amount of radioactive material released to the environment. It is shown how the concept of equilibrium breakdown can be applied in order to assess the radiological impact. (Author) 8 refs

Possibilities for a constitutional embodiment of environment protection

International Nuclear Information System (INIS)

Hattenberger, D.

1991-03-01

The main topic is the question of adequacy and desirability of a constitutional rule for the protection of the environment with regard to the specific Austrian situation and the extensive discussion about this topic in German. As variants are discussed a human right of environment, objective categories of constitutional rules (constitutional aims of state's policy) and procedural or organisational rules. It begins with an explanation of the general responsibility of states in the field of environment protection and a determination of the term 'environment '. In respect of a human right first already guaranteed rights are examined for their relevance in the field of conservation with regard to the change in the understanding of human rights. Then arguments pro and against a specific right to environment are mentioned and appraised. With regard to the counter-arguments a subjective right should not be incorporated. A revision of the present concept of human rights would be necessary. Similar arguments are mentioned against the constitution of an objective norm in respect of some judicial decisions of the Austrian Constitutional Court. The problem of the protection of the environment will not be solved with a constitutional rule. It would raise new problems, which would damage the constitution as a fundamental order of human living together. (author)

Using the 'protective environment' framework to analyse children's protection needs in Darfur.

Science.gov (United States)

Ager, Alastair; Boothby, Neil; Bremer, Megan

2009-10-01

A major humanitarian concern during the continuing crisis in Darfur, Sudan, has been the protection of children, although there has been little in the way of comprehensive analysis to guide intervention. Founded on a situational analysis conducted between October 2005 and March 2006, this paper documents the significant threats to children's well-being directly linked to the political conflict. It demonstrates the role of non-conflict factors in exacerbating these dangers and in promoting additional protection violations, and it uses the 'protective environment' framework (UNICEF Sudan, 2006a) to identify systematic features of the current environment that put children at risk. This framework is shown to provide a coherent basis for assessment and planning, prompting broad, multidisciplinary analysis, concentrating on preventive and protective action, and fostering a systemic approach (rather than placing an undue focus on the discrete needs of 'vulnerable groups'). Constraints on its present utility in emergency settings are also noted.

A perspective on the ICRP approach to Radiation protection of the environment

International Nuclear Information System (INIS)

Mossman, K.L.

2003-01-01

The ICRP, in response to concerns by the environmental community, has begun the process of addressing radiation protection of non-human species. Concerns have been raised that the current framework for radiation protection fails to adequately protect the environment. Although most everyone agrees that some change to the ICRP radiation protection framework is called for, the extent of the revision is debatable. In May 2000, the ICRP set up a Task Group to provide advice on the development of a policy for the protection of the environment and to suggest a framework for environmental protection based on scientific, ethical, and philosophical principles. Based on Task Group input, ICRP intends to develop a framework for protection of the environment that can be integrated into an overall system of protection. This paper explores four major issues that serve to identify questions that ICRP should consider in its 2005 recommendations regarding radiation protection of the environment: (1) the role of ICRP, (2) defining the environment and criteria for protection, (3) the framework for environmental protection, and (4) risk management.

Protection of the Abiotic Environment

Michel, R.; Hutmacher, K. E.; Landfermann, H. H.

2004-01-01

Environmental protection against the dangers arising from ionizing radiation, radioactive materials, and other harmful substances is more than to avoid acute dangers or risks for humans or for non-human living organisms. To allow for a sustainable development the abiotic part of the environment must not be neglected in concepts of environmental protection. The environmental impact of some selected long-lived anthropogenic radionuclides is used to exemplify adverse effects for which a unified approach is needed. To this end, indicators are needed for the assessment of the human impact on the abiotic environment which allows to compare different human actions with respect to sustainability and to choose appropriate measures in the competition for a sustainable development. Such indicators have to account for the dynamics of the different environmental compartments. Using the long-lived radionuclides 14C, 36Cl, 85Kr, and 129I as examples, the importance to consider dynamical models and ecological lifetimes in quantifications of the human impact on the environment is emphasized. Particular problems arise from the natural occurrences and variability of radionuclides and other harmful substances. Suitable indicators for the assessment of human impact on the abiotic compartments air, water, and soil are discussed. (Author) 18 refs

In recent years, awareness of the vulnerability of the environment has increased, as evidenced by new and developing international policies for environmental protection, starting with the Rio Declaration of 1992. In the context of ionizing radiation, the existing international approach is largely based on providing for the protection of humans, but this is being critically reviewed in several international fora. It is in this context that the Third International Symposium on Protection of the Environment from Ionising Radiation (SPEIR 3) was held between 22 and 26 July 2002, in Darwin, Australia. The symposium focused on issues related to the development and application of a system of radiation protection for the environment. The symposium programme included sessions dedicated to: ongoing research on the effects, responses and mechanisms of the interactions of ionizing radiation with biota; policy and ethical dimensions of the development of a framework for environmental radiation protection; and the development and use of methods and models for evaluating radiation as a stressor to the environment. Three workshops were held to allow for detailed discussion of each of these subjects. This symposium was the third in a series. The first International Symposium on Ionising Radiation: Protection of the Natural Environment, was held in Stockholm, Sweden, 20-24 May 1996. This symposium was organized jointly by the Swedish Radiation Protection Institute (SSI) and the Atomic Energy Control Board (AECB) of Canada, and the proceedings were published by the Akademitryck AB, Edsbruk, Sweden in 1996. The second International Symposium on Ionizing Radiation: Environmental Protection Approaches for Nuclear Facilities, was held in Ottawa, Canada, 10-14 May 1999, and was organized by the Canadian Nuclear Safety Commission (CNSC), the Supervising Scientists Group of Environment Australia, and the Swedish Radiation Protection Institute (SSI).

Hinged concrete covers protect pipelines. [Protection of submarine pipelines from underscouring, trawlboards, and dragging anchors

Energy Technology Data Exchange (ETDEWEB)

1977-09-01

Providing effective protection for oil and gas pipelines is proving to be a difficult and expensive business, particularly in heavily used and environmentally sensitive waters such as the North Sea. The Danish Company Seditech has produced a design for ''hinged'' pipeline covers in concrete which are claimed to offer an effective solution to the problem. Model tests are currently (end of August 1977) being carried out at Trondheim, Norway, and this will be followed by a six-month feasibility study into the design of a suitable underwater installation vehicle. The aim is to produce total costs of the same order as pipe burial. The first step towards this has been achieved, as another Danish company has developed a combined vibration/pressure moulding system which allows individual cover elements to be produced in 3 to 5 min.

Protection of the environment from ionising radiation: ethical issues

2002-01-01

The paper identifies some of the main ethical issues concerning the protection of the environment from radiation and suggests ways in which ethics can aid in developing a system of protection. After a presentation of background on ethical theory and environmental ethics, three main issues related to practical environmental protection are discussed: First, the question of who or what has moral standing; second the appropriate level of protection; and third compatibility with other environmental stressors. In summary, the paper argues that there are strong ethical grounds for efforts to provide for the protection of the environment and that, all other things being equal, there is no reason to treat ionising radiation differently to other environmental stressors.

Development of multi-year land cover data to assess wildfire impacts to coastal watersheds and the nearshore environment

Science.gov (United States)

Morrison, Katherine D.

In the Mediterranean ecosystems of coastal California, wildfire is a common disturbance that can significantly alter vegetation in watersheds that transport sediment and nutrients to the adjacent nearshore oceanic environment. We assess the impact of two wildfires that burned in 2008 on land cover and to the nearshore environment along the Big Sur coast in central California. We created a multi-year land cover dataset to assess changes to coastal watersheds as a result of fire. This land cover dataset was then used to model changes in nonpoint source pollutants transported to the nearshore environment. Results indicate post-fire increases in percent export compared to pre-fire years and also link wildfire severity to the specific land cover changes that subsequently increase exports of pollutants and sediment to the nearshore environment. This approach is a replicable across watersheds and also provides a framework for including the nearshore environment as a value at risk terrestrial land management revolving around wildfire, including suppression, thinning, and other activities that change land cover at a landscape scale.

Australia's proactive approach to radiation protection of the environment: how integrated is it with radiation protection of humans?

Science.gov (United States)

Hirth, G A; Grzechnik, M; Tinker, R; Larsson, C M

2018-01-01

Australia's regulatory framework has evolved over the past decade from the assumption that protection of humans implies protection of the environment to the situation now where radiological impacts on non-human species (wildlife) are considered in their own right. In an Australian context, there was a recognised need for specific national guidance on protection of non-human species, for which the uranium mining industry provides the major backdrop. National guidance supported by publications of the Australian Radiation Protection and Nuclear Safety Agency (Radiation Protection Series) provides clear and consistent advice to operators and regulators on protection of non-human species, including advice on specific assessment methods and models, and how these might be applied in an Australian context. These approaches and the supporting assessment tools provide a mechanism for industry to assess and demonstrate compliance with the environmental protection objectives of relevant legislation, and to meet stakeholder expectations that radiological protection of the environment is taken into consideration in accordance with international best practice. Experiences from the past 5-10 years, and examples of where the approach to radiation protection of the environment has been well integrated or presented some challenges will be discussed. Future challenges in addressing protection of the environment in existing exposure situations will also be discussed.

Non-governmental environmental organisations (environmental NGOs) may consider the issue of radiological protection of the environment differently to other interested parties such as regulators or industry. While environmental NGOs are broadly positive towards the current emphasis and engagement on radiological protection of the environment per se, there remain concerns about the precise meaning of the term and the ultimate objectives of the current initiatives. Various strategies are studied and discussed. The disposal of radioactive waste at sea is discussed and a case study presented. What the environmental NGOs are looking for is focused upon and various environmental protection systems are discussed (tk)

Protection of the disabled in the work environment

Jovanović Predrag P.

2015-01-01

Full Text Available The disabled enjoy special protection at work (in the work environment. The importance of this protection essentially determines the status of the disabled in the society, because it is connected with the work of the disabled with which get the means of life, but they are also brought into an equal position with other persons that do not have disability and whose working abilities are not reduced. There is a lot of vagueness in terms of terminological and meaning determination of the concept of disability, both in the international and the domestic law. We tried to elaborate the issue of disability in the paper firstly in the terminological and meaning sense and then to present international legal and domestic platform of their protection at work connected with the work, too (the work environment. Special emphasis was put on the concept of the disabled worker and their equal protection, with a critic review on the existing solutions in the effective law.

Nuclear terrorism and legal protection of environment

International Nuclear Information System (INIS)

Ahmad-zada, Z.; Aliev, D.

2003-01-01

Full text: For the last years the terrorism has significantly changed. If 20-30 years ago terrorists would kidnap famous politicians or hijack planes, but at this stage they switched to massive destruction of innocent people. Now the problem of struggle against nuclear terrorism becomes very actual problem. The nuclear terrorism is meant as an opportunity of accomplishment of act of terrorism with use of the nuclear weapon, or accomplishment of explosions on atomic power stations and other objects of an atomic energy. Threats to nuclear objects become more and more often and appreciable. In the world there were some similar cases of threat to nuclear objects from the part of terrorists, and also cases of use by terrorists of nuclear, chemical and bacteriological substances. These cases testify to real threat of use by terrorists of the weapon of mass destruction. It is natural, that accomplishment of acts of terrorism on these objects can lead to ecological catastrophe and can put an irreparable loss to an environment and process of social development. Up to the middle of sixtieth years of twentieth century protection of an environment was not put forward as an independent political problem, and its scientific substantiation has not been developed enough as a diversified, complex, global problem. Only dynamical development in seventieth - eightieth years of scientific bases of global problems has allowed to allocate the rules of law concerning to protection of an environment, into special group. International legal protection of ecology was precisely allocated now in system of the general international law as independent, specific sphere of regulation. The principle of inadmissibility of radioactive pollution of environment covers both military, and peace area of use of nuclear power. Formation and the statement of this special principle of International law of the Environment takes place in two ways - contractual and usual, with observance by the states of

Issues around radiological protection of the environment and its integration with protection of humans: promoting debate on the way forward

This paper explores issues to consider around integrating direct, explicit protection of the environment into the current system of radiological protection, which is focused on the protection of humans. Many issues around environmental radiological protection have been discussed, and ready-to-use toolboxes have been constructed for assessing harm to non-human biota, but it is not clear how (or even if) these should be fitted into the current system of protection. Starting from the position that the current approach to protecting the environment (namely that it follows from adequately protecting humans) is generally effective, this paper considers how explicit radiological protection of the environment can be integrated with the current system, through developing a 'worked example' of how this could be done and highlighting issues peculiar to protection of the environment. The aim of the paper is to promote debate on this topic, with the ultimate aim of ensuring that any changes to the system are consensual and robust

Protection of the environment against emissions

Gas exposure experiments with plants do not reflect their relative resistance to air pollutants in nature. For example, such experiments showed that vegetables are the plants most sensitive to air pollutants. If the environment is observed closely, however, it will be found that deciduous trees show symptoms of air pollution damage much earlier. This can be explained by the fact that vegetables are frequently protected by buildings or trees. Thus, plant resistance cannot be evaluated correctly without taking the environment into account. With this approach, it can be concluded that coniferous trees are hardest hit by air pollution. If they grow in the vicinity of a deciduous forest, they will disappear first. However, crops and deciduous trees can still be grown in industrial areas. There are three ways to protect coniferous trees in an industrial area: by good stack gas dispersion using high stacks; by cleaning the raw material or by using non-toxic material; and by removing dust and pollutants from the emissions. Despite such measures, a minimum of air pollution will remain. In view of this fact, pollution-resistant plants ought to be selected for cultivation in such areas; their growth conditions (soil, water supply, etc.) must be optimized, and a belt of protective plants must be created. 24 references, 4 figures.

Radiological protection of the environment: the path forward to a new policy?

International Nuclear Information System (INIS)

2002-01-01

The international system of radiological protection is currently being revised with the aim of making it more coherent and concise. During the revision process, particular attention is being given to the development of an explicit system for the radiological protection of the environment in addition to that of human beings. In order to support the ongoing discussions of the international community of radiological protection experts, these proceedings try to answer the questions: Is there an international rationale behind the wish to protect the environment from radiation? Do we have enough scientific information to develop and define a broadly accepted policy? What are the socio-political dynamics, beyond science, that will influence policy on radiological protection of the environment? What are the characteristics of the process for developing a system of radiological protection of the environment? These proceedings comprise the views of a broad range of invited speakers, including policy makers, regulators, radiological protection and environmental protection professionals, industry, social scientists and representatives of both non-governmental and intergovernmental organisations.

Six and a half years after the accident at Fukushima Daiichi nuclear power plant, an area of existing exposure situation remains. One of the main concerns of people is the higher level of ionising radiation than before the accident, although this is not expected to have any discernible health effect. Since the accident, several 'abnormalities' in environmental organisms have been reported. It is still not clear if these abnormalities were induced by radiation. It appears that the impact of the released radioactivity has not been sufficient to threaten the maintenance of biological diversity, the conservation of species, or the health and status of natural habitats, which are the focus in environmental protection. This highlights a difference between the protection of humans and protection of the environment (individuals for humans and populations/species for the environment). The system for protection of the environment has been developed with a similar approach as the system for protection of humans. Reference Animals and Plants (RAPs) were introduced to connect exposure and doses in a way similar to that for Reference Male and Reference Female. RAPs can also be used as a tool to associate the level of radiation (dose rate) with the biological effects on an organism. A difference between the protection of humans and that of the environment was identified: an effect on humans is measured in terms of dose, and an effect on the environment is measured in terms of dose rate. In other words, protection criteria for humans are expressed in term of dose (as dose limits, dose constraints, and reference levels), whereas those for the environment are expressed in terms of dose rate (as derived consideration reference levels).

Geophysical methods in protected environments. Electrical resistivity tomography

There is a strong interest in protecting the environment with the aim of its long term preservation. Sometimes the heritage value of these natural areas is related to their biodiversity as there are restricted ecosystems that depend directly on them. In other cases there a singular geological record might exist, essential for the understanding of certain processes affecting the planet, such as volcanic events or glacial periods. To achieve the protection and conservation of these areas it is necessary to generate knowledge about the distribution of geological materials and groundwater masses, to study the parameters that dominate the behaviour of these systems and then define those elements that require special protection or attention. In these protected environments, research methods with a minimal environmental impact should be used. Therefore, indirect methods, such as geophysical techniques, are reliable and complementary tools with a minimum environmental impact and are therefore useful for research these unique areas. The IGME has conducted several geophysical surveys in different protected environments in Spain with the aim of achieving a better understanding, and thus facilitate their preservation and exploitation in a sustainable manner. In this paper we present a review of some case studies where geophysical methods have been used. In all the cases electrical resistivity tomography has been the axis of the geophysical research and stands out due to its great effectiveness. The main objective of this communication is to divulgate and increase awareness of the important role that these geophysical methods can play in the sustainable study of these unique places. [es

Protective or damage promoting effect of calcium carbonate layers on the surface of cement based materials in aqueous environments

Schwotzer, M.; Scherer, T.; Gerdes, A.

2010-01-01

Cement based materials permanently exposed to aggressive aqueous environments are subject to chemical changes affecting their durability. However, this holds also for tap water that is considered to be not aggressive to cementitious materials, although in that case a formation of covering layers of CaCO 3 on the alkaline surfaces is commonly supposed to provide protection against reactive transport processes. Thus, investigations of the structural and chemical properties of the material/water interface were carried out in laboratory experiments and case studies to elucidate the consequences of surface reactions for the durability of cement based materials exposed to tap water. Focused Ion Beam investigations revealed that a protective effect of a CaCO 3 covering layer depends on its structural properties, which are in turn affected by the hydro-chemical conditions during crystallization. Surface precipitation of CaCO 3 can trigger further chemical degradation, if the required calcium is supplied by the pore solution of the material.

The environment sustainable development and biota protection, including the environment radiation protection are issues of nowadays interest in the society. An activity is ongoing on the development of a system of radiation protection for non-human biota. Anthropocentric and eco-centric principles are widely discussed. ICRP Publications 103, 108, 114 and many other reports and articles refer to the topic of environmental protection, reference animals and plants set, corresponding transfer parameters, dose models and derived consideration reference levels. There is still an open field for discussion of methods and approaches to get well-established procedure to assess environmental risks of radiation impacts to different organisms, populations and ecosystems. A huge work has been done by the ICRP and other organizations and research groups to develop and systematize approaches for this difficult subject. This activity, however, is not everywhere well-known and perceived, and more efforts are needed to bring ideas of eco-centric strategy in the environment radiation protection not only to public but to specialists in many countries as well. One of the main points of interest is an assessment of critical doses and doses rates for flora and fauna species. Some aspects of a possible procedure to find their estimates are studied in this work, including criteria for datasets of good quality, models of dose dependence, sensitivity of different umbrella endpoints and methods of original massive datasets treatment. Estimates are done based on information gathered in a database on radiation-induced effects in plants. Data on biological effects in plants (umbrella endpoints of reproductive potential, survival, morbidity, morphological, biochemical, and genetic effects) in dependence on dose and dose rates of ionizing radiation have been collected from reviewed publications and maintained in MS Access format. The database now contains about 7000 datasets and 25000 records

The development of the IAEA policy on the radiological protection of the environment

International Nuclear Information System (INIS)

Linsley, G.

2002-01-01

Since its creation in 1957, and in accordance with its statute, the IAEA has established standards of safety for protection of health in the fields of nuclear installations safety, radiation protection, the transport of radioactive materials and radioactive waste management, including the control of radioactive releases to the environment. In this context, the IAEA has a long history of involvement in matters related not only to the protection of humans but also to the protection of other species from the effects of radioactivity in the environment. Concern about the environment has arisen for different reasons over the years, starting with questions about the potential effects on non-human species of fall-out from nuclear weapons testing and of radioactive discharges to atmosphere and the oceans. Later, the concern was focussed on the possible harm to non-human species caused by the dumping of solid waste at sea. The IAEA has responded to requests from other UN bodies and from international conventions to evaluate these potential hazards and to establish protection criteria. Social and political attitudes have gradually changed towards the environment mainly due to a growing realisation that the environment is vulnerable to the effects of human activities. This change has been reflected in the outcomes of major UN conferences on the environment in 1972 and 1992 and, accordingly, the emphasis of international and national policies towards the environment has increasingly shifted towards protective measures and strategies that include other species. Thus, the protection of the environment from the effects of ionising radiation has taken on a new importance. The IAEA, together with other relevant international organisations, is working to develop an agreed environmental protection strategy to counter the possible effects of ionising radiation, building on the work done over the last 30 years but taking due account of the new attitudes to the subject.

Environment protection: The current challenge in radioecology

Science.gov (United States)

Bréchignac, F.

2012-04-01

Radioecology, a multifaceted scientific discipline which addresses environmental issues relevant to radioprotection, has for a long time been focused on environmental transfers through the environment to feed the needs of human radioprotection. This quite anthropocentric initial scope is now moving to a more ecocentric view capable of assessing ecological risk mediated by ionising radiation. The central issue consists in reaching an ability to understand the effects of radiation on the environment components, from individual organisms up to populations of species and ecosystems, together with their interaction with the abiotic compartments. Dominated by operational goals, the system of radiological protection of the environment which is under development emphasises a concept based upon reference organisms supported by traditional toxicological data on individual organisms. Whilst there are immediate advantages to this approach (pragmatism, consistency with other approaches in use for man and biota), there are also clear limitations which need to be acknowledged and further considered. The most important probably is to rely on effects data gathered almost exclusively for individual organisms to meet protection goals which are usually set at population and ecosystem levels. Overcoming this limitation leads to scientific and methodological approaches featuring the ecosystem concept.

Radiation protection of the environment: anthropocentric and eco-centric principles

International Nuclear Information System (INIS)

Alexakhin, R.M.; Fesenko, S.V.

2004-01-01

The second half of the 20. century was dominated in the field of radiation protection by the anthropocentric concept stated by the International Commission on Radiological Protection (ICRP). According to this concept 'if radiation standards protect man then biota are also adequately protected from ionizing radiation'. At the end of the 20. beginning of the 21. centuries in the area of radiation protection of nature an eco-centric strategy is beginning to develop where emphasis has swung to the protection of biota in their environment. Inadequacy of ICRP's anthropocentric concept is reported. Issues are discussed such as ecological dosimetry, non-equi-dose irradiation of man and biota, criteria for estimating radiation induced changes in biota and man, as well as the need to harmonize permissible exposure doses to man and biota. An urgent need is stressed to develop a single (synthetic) concept of radiation protection which simultaneously ensures protection of human health and biota well-being in their environment. This concept is to be based on the recognition of the integrity of socio-natural ecosystems where man and biota are considered as a unity. (author)

The alleged conflicting situation between environmental protection and liberalisation can be resolved if we make both the market and competition serve the interests of environmental and climate protection to a greater extent. The exploitation of the allocation efficiency of markets for protecting the environment is legitimate according to the experience that the well-husbanded and efficient use of sparse resources is not achieved by government planning and control, but allowing market prices to form on functioning markets which reflect the shortage of such resources. This approach would also put into perspective the much debated conflict between economy and ecology. (orig.) [de

Space Ethics and Protection of the Space Environment

Williamson, Mark

2002-01-01

The construction of the International Space Station in low Earth orbit and the formulation of plans to search for life on Mars - one day by means of manned missions - indicate that mankind is intent on making the space environment part of its domain. Publicity surrounding space tourism, in-space `burials' and the sale of lunar `real estate' suggests that, some time in the 21st century, the space environment will become an extraterrestrial extension of our current business and domestic environment. This prompts the question of our collective attitude towards the space environment and the degree to which we should regulate its use and protect it for future generations. What, indeed, are the ethical considerations of space exploration and development? Ethics can be defined as "the philosophical study of the moral value of human conduct, and of the rules or principles that ought to govern it". More practically, it represents "an approved code of behaviour" adopted, for example, by a group or profession. If a set of ethics is to be developed for space, it is important that what we refer to as the `space community', or `space profession', is intimately involved. Indeed, if it is not, the profession risks having the job done for it, for example by politicians and members of the general public, who for their own reasons may wish to place restrictions on space development, or ban it altogether. The terrestrial nuclear power industry, for example, has already suffered this fate, while widespread ignorance of the subject has led to a moratorium on the use of RTGs in spacecraft. However, there is a danger in the discussion of ethics that consideration is confined to the philosophical aspects, thus excusing those involved from providing practical solutions to the problems that emerge. The fact that mankind has already affected, and arguably damaged, the space environment transports the discussion beyond the philosophical realm. This paper offers a pragmatic analysis of one

2002-01-01

Since the late 1990's the work of the International Atomic Energy Agency (IAEA), relating to the effects of radiation on species other than man, has been focused on defining and clarifying issues related to the development of an international framework to address the protection of the environment, or living elements within it, from the effects of ionising radiation. In 1999, IAEA-TECDOC-1091, entitled Protection of the Environment from the Effects of Ionising Radiation: A Report for Discussion, was published. This report explored the various issues and approaches that would need to be resolved in order to establish an environmental protection framework and associated criteria. Relevant principles, policies and regulatory approaches were reviewed and the factors that may affect future developments of a protection system were identified. The report concluded that, although improved information was required in several areas, there was sufficient knowledge of the effects of ionising radiation on organisms to move forward. Following publication of this report, IAEA activities have continued on: a) the elaboration of the ethics and principles underlying environmental protection, paying particular attention to their implications for the development of an approach for radiological protection of the environment; and, h) fostering information exchange by holding a series of Specialists Meetings on environmental radiation protection, the most recent of which took place in November 2001. The long-term aim of this work is to establish consensual IAEA Safety Standards on environmental radiation protection, in collaboration with other relevant international organisations. This paper will provide a summary of IAEA work to date on the development of a framework for protection of the environment from ionising radiation, paying particular attention to the recently published IAEA-TECDOC-1270 on Ethical Considerations in protecting the Environment front the Effects of Ionising

1.1. INTRODUCTION Plastic covering, either framed or floating, is now used worldwide to protect crops from unfavorable growing conditions, such as severe weather and insects and birds. Protected cultivation in the broad sense, including mulching, has been widely spread by the innovation of plastic films. Paper, straw, and glass were the main materials used before the era of plastics. Utilization of plastics in agriculture started in the developed countries and is now spreading to the developing countries. Early utilization of plastic was in cold regions, and plastic was mainly used for protection from the cold. Now plastic is used also for protection from wind, insects and diseases. The use of covering techniques started with a simple system such as mulching, then row covers and small tunnels were developed, and finally plastic houses. Floating mulch was an exception to this sequence: it was introduced rather recently, although it is a simple structure. New development of functional and inexpensive films trig...

Alternative cover design

1988-11-01

The special study on Alternative Cover Designs is one of several studies initiated by the US Department of Energy (DOE) in response to the proposed US Environmental Protection Agency (EPA) groundwater standards. The objective of this study is to investigate the possibility of minimizing the infiltration of precipitation through stabilized tailings piles by altering the standard design of covers currently used on the Uranium Mill Tailings Remedial Action (UMTRA) Project. Prior. to the issuance of the proposed standards, UMTRA Project piles had common design elements to meet the required criteria, the most important of which were for radon diffusion, long-term stability, erosion protection, and groundwater protection. The standard pile covers consisted of three distinct layers. From top to bottom they were: rock for erosion protection; a sand bedding layer; and the radon barrier, usually consisting of a clayey sand material, which also functioned to limit infiltration into the tailings. The piles generally had topslopes from 2 to 4 percent and sideslopes of 20 percent

The IAA Cosmic Study 'Protecting the Environment of Celestial Bodies'

Rettberg, Petra; Hofmann, Mahulena; Williamson, Mark

The study group tasked with producing this International Academy of Astronautics (IAA) `Cosmic Study' on Protecting the Environment of Celestial Bodies was formed under the aus-pices of IAA Commission V (Space Policy, Law Economy). The members of the international, multidisciplinary team assembled to undertake the Study accept, as a premise, the Planetary Protection Policy guidelines developed by COSPAR, which differentiate the degree of protec-tion according to the type of space activity and the celestial body under investigation (such that fly-by missions have less stringent requirements than lander missions, while Mars is `better protected' than the Moon). However, this Study goes deliberately beyond the interpretation of `Planetary Protection' as a set of methods for protecting the planets from biological con-tamination and extends consideration to the geophysical, industrial and cultural realms. The Study concludes that, from the perspective of current and future activities in outer space, present measures aimed at protecting the space environment are insufficient. Deficiencies in-clude a lack of suitable in-situ methods of chemical and biological detection and the absence of a systematic record of radioactive contaminants. Other issues identified by the Study include an insufficient legal framework, a shortage of effective economic tools and a lack of political will to address these concerns. It is expected that new detection methods under development, and the resultant increase in microbiological knowledge of the planetary surfaces, will lead to changes in the COSPAR planetary protection guidelines and bioburden limits. It is important, however, that any new approaches should not hamper future exploration and exploitation of celestial bodies more than absolutely necessary. The Study addresses the need to find a balance between protection and freedom of action. From a legal perspective, the Study concludes that a general consensus on protection of the

A number of international organisations are focussing on a revision of radiation protection policy from the existing system which addresses only effects on man, to one which also addresses effects on the wider environment. These developments are expected to effect a wide range of stakeholders, including industry, regulators, scientists, users and the public. With this in mind a 'Consensus Conference on Protection of the Environment' was arranged as part of an International Seminar on 'Radiation Protection in the 21st Century: Ethical, Philosophical and Environmental Issues' held at the Norwegian Academy of Science and Letters. The conference attracted 46 international experts representing various disciplines and affiliations including Environmental Science, Health Physics, Radioecology, Ethics and Philosophy and a wide spectrum of perspectives bearing on the question of radiation protection of the environment. The conference was novel in that the participants were professionals rather than laypersons, and the purpose of the consensus procedure was to identify areas of agreement as an input to the ongoing regulatory developments. The success and innovation of the model is reflected in the significant areas of agreement identified in the final consensus statement, and the subsequent interest at an international level. Participants also noted the need for furthering the debate through ongoing work. Notable issues were the harmonisation of standards for radiation with other environmental stressors, guidance for balancing different interests and values within practical management, and the need for assessment criteria

High-quality, safe, and sufficient drinking water is essential for life: we use it for drinking, food preparation and cleaning. Agriculture is the biggest source of pesticides and nitrate pollution in European fresh waters. The overarching objective of the recently approved H2020 project WATERPROTECT is to contribute to effective uptake and realisation of management practices and mitigation measures to protect drinking water resources. Therefore WATERPROTECT will create an integrative multi-actor participatory framework including innovative instruments that enable actors to monitor, to finance and to effectively implement management practices and measures for the protection of water sources. We propose seven case studies involving multiple actors in implementing good practices (land management, farming, product stewardship, point source pollution prevention) to ensure safe drinking water supply. The seven case studies cover different pedo-climatic conditions, different types of farming systems, different legal frameworks, larger and smaller water collection areas across the EU. In close cooperation with actors in the field in the case studies (farmers associations, local authorities, water producing companies, private water companies, consumer organisations) and other stakeholders (fertilizer and plant protection industry, environment agencies, nature conservation agencies, agricultural administrations) at local and EU level, WATERPROTECT will develop innovative water governance models investigating alternative pathways from focusing on the 'costs of water treatment' to 'rewarding water quality delivering farming systems'. Water governance structures will be built upon cost-efficiency analysis related to mitigation and cost-benefit analysis for society, and will be supported by spatially explicit GIS analyses and predictive models that account for temporal and spatial scaling issues. The outcome will be improved participatory methods and public policy instruments

Protection of the natural environment - philosophy and criteria

Larsson, Carl-Magnus; Sundell-Bergman, S.

Nuclear operations give rise to small releases of radionuclides to the environment either under controlled conditions (immediate releases) or uncontrolled from waste repositories in the near or far future (delayed releases). The radiation doses to man from the discharges can be estimated using radioecological and dispersion modelling methods. The system for limiting exposure of individual members of the public is currently based on the recommendation by the ICRP. Their risk philosophy, which stems from the fact that the probability of cancer resulting from radiation will be linear with dose, has hitherto gained broad acceptances for setting authorised dose-limits for man. A discussion has recently emerged on the protection of the natural environment from harmful radiation effects. In this case there is concern for the viability of the population rather than the individuals. As our understanding of important mechanisms regarding the protection of the environment is limited it seems appropriate to adopt a precautionary approach. In matters where little is known about the risks the precautionary principle has a major role to play. Concomitantly, the best available technology (BAT), as stated in the precautionary principle, could be employed to minimise discharges of radionuclides. The development of a regulatory frame-work requires that an objective is set and that standards and indicators are derived in a multi-tiered approach. By applying the precautionary principle for environmental radiation protection the safety margins have to increase. However improving knowledge may in due time lead to more rational decision-making

Globalization and protection of environment

International Nuclear Information System (INIS)

Panahandeh, M.

2003-01-01

In recent years two trends have come into conflict in the international arena. The first is the globalization of economy and the second is the increased public concern over the environmental impact of economic activities and awareness of the global dimensions of many environmental problems. Nowadays confrontation of the issue of globalization and economic liberalization and protect of the environment is a matter of heated debate and environmentalists see globalization posing a threat to environment standards. The effects of liberalization on environment in the developing world have been analyzed from the perspective of the pollution- have hypothesis. The hypothesis suggests that the liberalization encourages a spatial displacement of the so-called d irty o r pollution- intensive industries from the developed countries with stricter environmental regulations to their preferential location in developing countries which enjoy minimal environmental regulations or capacity for environmental monitoring and enforcement. It also suggests that economic policies which promote foreign investment in the natural resources of developing countries will increase rates of natural-resource extraction in the developing world. according to the theory, the translational firms will employ cheep technologies in developing countries which are not environmental sound and no longer permitted to use in the industrialized world

This study demonstrates that containment of municipal and hazardous waste in arid and semiarid environments can be accomplished effectively without traditional, synthetic materials and complex, multi-layer systems. This research demonstrates that closure covers combining layers of natural soil, native plant species, and climatic conditions to form a sustainable, functioning ecosystem will meet the technical equivalency criteria prescribed by the U. S. Environmental Protection Agency. In this study, percolation through a natural analogue and an engineered cover is simulated using the one-dimensional, numerical code UNSAT-H. UNSAT-H is a Richards. equation-based model that simulates soil water infiltration, unsaturated flow, redistribution, evaporation, plant transpiration, and deep percolation. This study incorporates conservative, site-specific soil hydraulic and vegetation parameters. Historical meteorological data are used to simulate percolation through the natural analogue and an engineered cover, with and without vegetation. This study indicates that a 3-foot (ft) cover in arid and semiarid environments is the minimum design thickness necessary to meet the U. S. Environmental Protection Agency-prescribed technical equivalency criteria of 31.5 millimeters/year and 1 x 10{sup -7} centimeters/second for net annual percolation and average flux, respectively. Increasing cover thickness to 4 or 5 ft results in limited additional improvement in cover performance.

TABITA CORNELIA ADAMOV

2008-05-01

Full Text Available The future of the agriculture is a problem very frequently discussed by the specialists. During these debates, the organic agriculture has an advantage. The organic agriculture is taking into consideration two aspects: the human being and the environment. It is based on the prohibition of using chemicals like pesticides, herbicides or chemical fertilizers. This will offer healthy and natural products, but also will protect the environment. The usage of chemicals harms the environment and they remain in the soil for a long time. The substances used to protect the crops destroy the biodiversity, killing the insects, not only the harmful ones. The preservation of the biodiversity and the quality of the environment is an important objective for the beginning of this millennium, extended by the concern for the population health, for food safety assurance and for the improvement of life conditions. The existence of the future human society depends on applying in practice the concept of lasting economical development.

Protection of the environment from the effects of ionizing radiation. A report for discussion

International Nuclear Information System (INIS)

1999-07-01

The acceptability of practices which involve the release of radionuclides into the environment, and of situations where residual radionuclides from accidents or improperly controlled practices exist in the environment, are generally assessed on the basis of implied radiation doses to humans. This approach is consistent with the recommendations of the International Commission on Radiological Protection (ICRP), which include the statement that 'the standard of environmental control needed to protect man to the degree currently thought desirable will ensure that other species are not put at risk'. The general applicability of this statement has been explored in previous IAEA and other publications. These concluded that the statement is generally valid but that reliance upon human based radiological protection criteria may not be adequate for all possible space or time scales. In recent years awareness of the vulnerability of the environment has increased and the need to protect it against the effects of industrial pollutants has been recognized. This trend is reflected in new and developing international policies for environmental protection. In the context of protection of the environment against ionizing radiation, the existing international approach is being challenged in some IAEA Member States and proposals are being made for strategies which provide for explicit protection of the environment. The present publication represents a first step towards establishing an internationally accepted philosophy and associated methodology for protecting the environment against ionizing radiations. The report reviews the various related issues and examines possible approaches to establishing criteria. It is intended for use in stimulating discussion on the subject in Member States. For its part, the IAEA intends to continue a programme of work in this area with the long term objective of providing specific recommendations on primary protection criteria and methods for

Aerotechnogenic Monitoring of Urban Environment on Snow Cover Pollution (on the Example of Voronezh City

Directory of Open Access Journals (Sweden)

Prozhorina Tatyana Ivanovna

2014-09-01

Full Text Available Snow cover is characterized by high sorption ability and represents an informative object in the process of identifying the technogenic pollution of urban environment. The article contains the results of the research on the chemical composition of the snow which fell in Voronezh in the winter period of 2013–2014. The coefficients of chemical elements concentration were calculated to provide objective characteristics of snow cover pollution. The authors analyze the connection between the presence of pollutants in snow and the level of technogenic impact. The obtained ranges of anomaly coefficients among anions reflect the composition of technogenic emissions. The mineralization of snow water reliably characterizes the intensity of anthropogenic impact on the urban environment, and the value of mineralization snow samples ranges from 62,6 (background to 183,9 mg/l. Maximum values of mineralization (more than 150 mg/l are typical for samples taken in transport area. High values of salinity (more than 120 mg/l are observed in snow samples taken in the industrial area, which confirms the high “technogenic pressure” on the urban environment in zones of industrial and transport potential of the city. The investigated functional areas can be arranged in the following series by descending level of contamination: transport area > industrial zone > residential and recreational areas > background territory. The study of the chemical composition of snow cover in the various functional areas of Voronezh allows to conclude that the pH level, mineralization and the content of suspended solids in snow waters characterize the intensity of anthropogenic pressure on the urban environment, and the composition of melt waters indicates the nature of its pollution.

Hernandez Armas, J.

2007-01-01

Paper education on Radiation Protection in health environments is essential to optimise the use of radiation for diagnostic or therapeutic purposes. The continuous increment in the number of available radiation emitting equipment in health environments and the generalisation of procedures, which imply important radiation exposures to patients, are expected to increase the overall doses to patients. A consequence of this will be the increment of harmful effects, especially, radiation induced cancer. General concern towards this respect has produced a generalisation of the requirements considered to be needed in a proper Radiation Protection education. Norms have been created for this purpose at both national and European level. here, the European and Spanish norms are reviewed. the applications of these norms are, also reviewed. Furthermore, the objectives of various platforms and European projects, aimed at improving the formation of health personnel on Radiation Protection, are presented. A conclusion of the review is that there exist significant differences in the syllabuses proposed for various professionals at different levels. Moreover, all the legislation collected in the norms has not been implemented in common practice. (Author) 24 refs

The economic, environmental and social development should not degrade the environment but it should leave it for the next generations in the state that it is presently or even better. The principle of sustainable agriculture is to cover the human needs for food without damage to the environment. The aim of the article was to research the farmers' awareness of the principle of sustainable agriculture and balanced fertilization and their influence on the environment. Among 100 farmers of the Tczew district (Poland) there was done questionnaire research on the determination rates of nitrogen fertilizers and on the regulation of fertilizers usage in Poland. Most of farmers declared a good knowledge of good agricultural practices and of balanced fertilization and the awareness of threats issuing from their activities. At the same time in Poland since the announcement of the Nitrate Directive of the former European Common Market (1992) up till now (2013) the application of nitrogen fertilizers doubled and the yield of wheat increased only by 15%, which means the increase of environmental burden with this chemical element.

The purpose of this presentation is to discuss the question of whether radiation protection should be extended to plants and animals. Until now the recommendations of ICRP have been focused exclusively on the protection of man from ionizing radiation. It was assumed that, if man is protected, the quality of the living environment is not impaired. In recent years adequate principles, recommendations and laws have become necessary in order to protect the environment from man made toxins. These recommendations aimed to conserve plants and animals, to maintain the diversity of species, the health and status of natural habitats and the natural resources of our planet, to warrant natural evolution and selection processes in order to transmit a healthy world to future generations. Reflections have been made as to whether particular protection of fauna and flora from ionizing radiation should be included. This article presents some considerations from the point of view of operational radiation protection and some comments to the work already done by ICRP committee 5. The final purpose is to invite the audience to make its own reflections and to communicate any criticisms, comments or suggestions to committee 5 of ICRP. (author)

Use of cover habitat by bull trout Salvelinus confluentus and lake trout Salvelinus namaycush in a laboratory environment

Science.gov (United States)

Meeuwig, Michael H.; Guy, Christopher S.; Fredenberg, Wade A.

2011-01-01

Lacustrine-adfluvial bull trout, Salvelinus confluentus, migrate from spawning and rearing streams to lacustrine environments as early as age 0. Within lacustrine environments, cover habitat pro- vides refuge from potential predators and is a resource that is competed for if limiting. Competitive inter- actions between bull trout and other species could result in bull trout being displaced from cover habitat, and bull trout may lack evolutionary adaptations to compete with introduced species, such as lake trout, Salvelinus namaycush. A laboratory experiment was performed to examine habitat use and interactions for cover by juvenile (i.e., habitat, with bull trout using cover and bottom habitats more than lake trout. Habitat selection ratios indicated that bull trout avoided water column habitat in the presence of lake trout and that lake trout avoided bottom habitat. Intraspecific and interspecific agonistic interactions were infrequent, but approximately 10 times greater for intraspecific inter- actions between lake trout. Results from this study provide little evidence that juvenile bull trout and lake trout compete for cover, and that species-specific differences in habitat use and selection likely result in habitat partitioning between these species.

An ecosystem approach is a holistic (i.e., top-down) strategy for protection of ecosystem structures and functions from perturbations. A task group of International Union of Radioecology 'Ecosystem Approach to Environment Protection' was launched in April, 2010. This task group is preparing a report on the following topics: (1) goals of environmental protection; (2) legislation about environmental protection; (3) assessment of the Reference Animals and Plants (RAP) concept in the general context of environmental protection; (4) limitations and uncertainties of the RAPs concept; (5) justification and merits of the ecosystem approach; (6) assessing the feasibility of the ecosystem approach; (7) research and development required for the ecosystem approach; and (8) recommendations with respect to radiation protection. The topics 1, 3, 4 and 5 have been almost completely prepared, and demonstrate that the ecosystem approach is required for radiation protection of the environment. On the other hand, methods of the ecosystem approach which should be adopted for radiation protection of the environment are not clear in the current draft report. They should be specified by reviewing the Convention on Biological Diversity, fish stock management and other activities where the ecosystem approach is already adopted. (author)

2016-01-01

The new European Basic Safety Standards in Radiation Protection (2013/59/Euratom) introduce 'environmental criteria' to protect human health in the long term. This innovation results from work in progress and from the recent positioning of international organizations and authorities in charge of radiation protection and its implementation, regarding the protection of wildlife against ionizing radiation. On the basis of the international state of the art, from the current regulatory context to existing approaches, the ERICA method has been identified as fully consistent with the ICRP approach and the most operational at the moment, due to its richness, flexibility and traceability. Most of the radiological risk assessments for wildlife published in the 5 last years used part or all of the ERICA approach, generally screening the radiological risk for wildlife from the first stage of the assessment, except for a few areas among those most impacted by radioactive contamination (Chernobyl area, uranium mining sites in Central Asia, etc.). This update of the knowledge in the field at the international level and the feedback on the analysis of regulatory files presented by nuclear operators led to 10 recommendations from the IRSN on the radiation protection of the environment and its implementation.

Does protecting humans protect the environment? A crude examination for UK nuclear power plants and the marine environment using information in the public domain

International Nuclear Information System (INIS)

Brownless, G P

2008-01-01

Current activity around radiological protection of the environment implies concerns over the effectiveness of the current approach to this-namely if humans are adequately protected, then so are non-human species. This study uses models and data currently available in the public domain to carry out a 'quick and dirty' examination of whether protecting humans does indeed imply that other species are well protected. Using marine discharges and human habits data for operational coastal UK nuclear power stations, this study compares doses to humans and a set of reference non-human species. The study concludes that the availability of data and models, and consequent ease of studying potential effects on non-humans (as well as humans), vindicates recent efforts in this area, and that these imply a high level of protection, in general, for non-human biota from UK nuclear power station marine discharges. In general terms, the study finds that protection of non-human biota relies on taking ingestion and external exposure doses to humans into account; where only one of these pathways is considered, the level of protection of non-human biota through protection of humans would depend on the radionuclide(s) in question.

Radiological considerations of the reactor cover gas processing system at the FFTF

1987-01-01

Radiological and environmental protection experience associated with the reactor cover gas processing system at the Fast Flux Test Facility (FFTF) has been excellent. Personnel radiation exposures received from operating and maintaining the reactor cover gas processing system have been very low, the system has remained free of radioactive particulate contamination through the first seven operating cycles (cesium contamination was detected at the end of Cycle 8A), and releases of radioactivity to the environment have been very low, well below environmental standards. This report discusses these three aspects of fast reactor cover gas purification over the first eight operating cycles of the FFTF (a duration of a little more than four years, from April 1982 through July 1986).

Health promotion is a priority of our time and planning and the evaluation of health and hygiene should be directed towards strategies to improve the well-being and lifestyles of the community. At the legislative level in Italy, the Ministry of Health, was established in 1958 with the task of providing for the collective health of the whole nation and in 1978, with Law 833, the National Health Service (NHS) was created which secured assistance and healthcare to all Italian citizens. The most important component of the entire health system is the Local Health Unit (USL) which has responsibility for prevention, treatment and rehabilitation, and highlights the importance of safeguarding the health, hygiene and safely at home and at work and the "hygiene of urban settlements and communities", ie environmental protection. One of the reasons for the delays in the promotion of environmental protection initiatives in Italy is to be found in the referendums of 1993, including the one which removed the tasks regarding environmental controls from the NHS. The temporary skills gap in the environmental field was filled with the 'National Agency for Environmental Protection (ANPA), which later became the Agency for Environmental Protection and Technical Services (APAT), and the regional level, the Regional Agencies Environmental Protection Agency (ARPA). Law 61/21 January 1994 joined the ARPA to the National Institute for Environmental Research and Protection (ISPRA). It is now necessary to implement a program that takes account of the damage caused to the environment and consequently the individual, which is totally committed the combination of the environment and human health and not, as in the recent past, as two distinct entities. In this sense, it is of fundamental importance the role of prevention departments to promote the organization networking and of individual companies' and individuals' skills, in fact.

Evaluation of burial ground soil covers

International Nuclear Information System (INIS)

Fenimore, J.W.

1976-11-01

Solid radioactive waste burial at the Savannah River Plant between 1955 and 1972 filled a 76-acre site. Burial operations then were shifted to an adjacent site, and a program was begun to develop a land cover that would: (1) minimize soil erosion; and (2) protect the buried waste from deep-rooted plants, since radionuclides can be recycled by uptake through root systems. In anticipation of the need for a suitable soil cover, five grass species were planted on 20 plots (4 plots of each species) at the burial ground (Facility 643-G) in 1969. The grass plots were planted for evaluation of viability, root depth, and erosion protection existing under conditions of low fertility and minimum care. In addition, 16 different artificial soil covers were installed on 32 plots (each cover on two plots) to evaluate: (1) resistance of cover to deterioration from weathering; (2) resistance of cover to encroachment by deep-rooted plants; and (3) soil erosion protection provided by the cover. All test plots were observed and photographed in 1970 and in 1974. After both grass and artificial soil covers were tested five years, the following results were observed: Pensacola Bahia grass was the best of the five cover grasses tested; and fifteen of the sixteen artificial covers that were tested controlled vegetation growth and soil erosion. Photographs of the test plots will be retaken at five-year intervals for future documentation

Protecting people and the environment - nuclear applications outside the energy sector

International Nuclear Information System (INIS)

Regge, P.P. de

2002-01-01

Nuclear technologies, isotope technologies, and applications of ionizing radiation are widespread, making important contributions to a continued worldwide improvement of the present standard of living and the protection of people and of the environment. The International Atomic Energy Agency (IAEA) develops and supports these technologies under the statute of the United Nations. Within this framework the Agency, among other items, promotes the exchange of information, the training of qualified personnel, the provision of the required equipment, and the drafting of international safety standards. Because of their special importance to people and the environment, mainly these areas are of interest: - nuclear medicine and health care, - veterinary medicine and livestock breeding, - soil cultivation and fertilization, - environmental protection and water supply, - plant cultivation, - pest control, - land mine clearing, protection of cultural assets. The IAEA, with its many decades of activity and experience, can boast of a large number of highly successful ventures. In many countries, the development and application of nuclear technologies have made important contributions, e.g., to improving the food situation, health care, and environmental protection. IAEA's continuing these activities is in the general interest of a promising international development and cooperation. (orig.) [de

Trends of world energy consumption and possibilities of environment protective power generation

International Nuclear Information System (INIS)

Frischengruber, K.

1991-01-01

The population of the world will duplicate within the next three to four decades. The primary energy consumption will increase accordingly. Considering the limited reach of our fossil energy resources and their negative impact on the global climate, alternative strategies for the power generation have to be developed. The contribution of the renewable energy sources will be important, but not sufficient, due to their high generation costs. The nuclear power, which already today participates essentially in the energy supply, will remain one of the most important options for environment protecting energy generation. Especially for the developing countries, which -in general- have currently a not covered energy demand, the build up of reasonable energy generation structures means enormous volumes of investments, which can only be financed with the assistance of the industrialized countries. Those, on the other hand, have to economize their energy consumption and have to undertake any effort in continuing with the development of clean, safe and competitive renewable resources. To provide increasing world population with sufficient energy and at the same time to reduce CO 2 emissions is one of the biggest challenges that mankind has ever faced. (Author)

Challenging the current strategy of radiological protection of the environment: arguments for an ecosystem approach

International Nuclear Information System (INIS)

Brechignac, F.; Doi, Masahiro

2009-01-01

The system of radiological protection of the environment that is currently under development is one contribution to the general need to adequately protect the environment against stress. Dominated by operational goals, it emphasizes conceptual and methodological approaches that are readily accessible today: reference organisms supported by individual-based traditional ecotoxicological data. Whilst there are immediate advantages to this approach (pragmatism, consistency with other approaches in use for man and biota), there are also clear limitations, especially in a longer run perspective, that need to be acknowledged and further considered. One can mention a few: uncertainties generated by the need for various extrapolations (from lower to higher levels of biological organisation, ...), various features missed such as potential ecological impact through impairment of ecosystem processes, trans-generational impacts as mediated through genomic instability, indirect effects mediated through trophic interactions or disruption of ecological balances, ... Such limitations have already been faced in other fields of environmental protection against other stressors, pushing a number of environment professionals to assign stronger emphasis on more systemic approaches. This review discusses the advantages and limitations of the current approach designed for the radiological protection of non-human biota in the broader context of environment protection as a whole, with especial reference to upcoming trends and evolutions. This leads in particular to advocating the need to boost scientific and methodological approaches featuring the ecosystem concept as a mean to access a unified goal of protection: preserving life sustainability through protection of ecosystem structure and functioning.

Integrated site investigation procedure for environment protection toward sustainable development

International Nuclear Information System (INIS)

Omar, R C; Roslan, R; Baharuddin, I N Z

2013-01-01

The spatial configuration of cities and their relationship to the urban environment has recently been the subject of empirical, theoretical and policy research. An awareness of environmental issues can assist policy makers, planners, developers and others to recognize the constraints imposed upon development due the physical environment especially in areas, which are susceptible to erosion, flooding and landslide. This paper highlights the key requirements for considering an assessment to protect our urban environment by incorporating three main factor i.e. policy practice, planning process and engineering investigation. Base on this three main factor the framework of the assessment is carried out. The assessment can be divided into three different categories, namely as investigation for planning, investigation for urban development and specialized investigation and mitigation. The minimum requirements for the planning and urban development investigation are listed. These guidelines suggest the level at which the various types of investigation should be carried out as well as the range of application, the scope and methodology to be used for different investigation. It is hoped that this procedure will provide guidance in the establishment and protection of urban ecosystem toward sustainable development.

Modernization and consolidation of the European radiation protection legislation. The new EURATOM radiation protection basic safety standards

International Nuclear Information System (INIS)

Mundigl, S.

2013-01-01

With the development of new basic safety standards for the protection against the dangers arising from ionising radiation, foreseen in Article 2 and Article 30 of the Euratom Treaty, the European Commission modernises and consolidates the European radiation protection legislation. The new Directive offers in a single coherent document, basics safety standards for radiation protection which take account of the status-quo of science and technology, cover all relevant radiation sources, including natural radiation sources, integrate protection of workers, members of the public, patients and the environment, cover all exposure situations, planned, existing, emergency, and harmonise numerical values with international standards. After having received very positive opinions of the Article 31 Group of Experts and the European Economic and Social Committee, the proposed Directive has reached agreement in the Working Party on Atomic Questions of the European Council (WPAQ). The Opinion of the European Parliament is expected in September 2013, which would allow a publication of the Directive in the Official Journal of the European Union by the end of 2013. (orig.)

Environment protection in the electric power supply of China. Status and perspectives

International Nuclear Information System (INIS)

Li Naihu; Chen Heng

1994-01-01

In the course of its reformatory opening policy during the last years, the economy of China has developed very rapidly. However, this strong economic growth led to serious deficits in the electric power supply. The growth rate of the gross national product was generally higher than that of electric power production during this period. Great efforts were made in China to solve this problem. Numerous new thermal power plants were constructed. These were exclusively fueled by coal, as gas and oil production is limited in China and these raw materials are exported or used by the industry. In the past the spheres of energy politics and ecopolitics in China were largely separate. Increasing pressure from within, as a consequence of growing pollution, and demands from outside to comply with international pollutant emission standards are leading to an integration of environment protection in China's energy policies. The present article describes how China copes with the contradicting demands of its economic plight and environment protection and how it is responding to international demands. Besides this it relates the situation of and future prospects for environment protection in China's electric power supply. (orig.) [de

Privedeno opisanie patenta. / Uniformity of protective camouflage installations significantly increases survivability of tanks on the move. This installation prevents an enemy from distinguishing a tank from a car or an empty trailer. A camouflage cover made of multilayer water-resistant material makes anti-tank shaped charge projectiles pre-detonate. Since most projectiles are designed for attacking ERA, the first detonation hits the camouflage cover instead of the armour. When the second detonation hits the ERA, its explosion neutralizes the shaped charge jet. This structure is considerably cheaper and much more effective than rubber protection models. The article analyses anti-tank combat means, 'smart' missile guidance methods and methods of fighting means of attack. It also gives methods of fighting 'smart' projectiles and the applications of this protective camouflage structure.

Root characteristics of cover crops and their erosion-reducing potential during concentrated runoff

Science.gov (United States)

de Baets, S.; Poesen, J.

2009-04-01

In the loam region in central Belgium, a lot of research has been conducted on the effects of cover crops for preventing splash and interrill erosion and on their nutrient pumping effectiveness. As this is a very effective erosion and environment conservation technique, planting cover crops during the winter season is widely applied in the loess belt. Most of these cover crops freeze at the beginning of the winter period. Consequently, the above-ground biomass becomes less effective in protecting the soil from water erosion. Apart from the effects of the above-ground biomass in protecting the soil against raindrop impacts and reducing flow velocities by the retarding effects of their stems, plant roots also play an important role in improving soil strength. Previous research showed that roots contribute to a large extent to the resistance of topsoils against concentrated flow erosion. Unfortunately, information on root properties of common cover crops (e.g. Sinapis alba, Phacelia tanacetifoli, Lolium perenne, Avena sativa, Secale cereale, Raphanus sativus subsp. oleiferus) is very scarce. Therefore, root density distribution with depth and their erosion-reducing effects during concentrated flow erosion were assessed by conducting root auger measurements and concentrated flow experiments at the end of the growth period (December). The preliminary results indicate that the studied cover crops are not equally effective in preventing soil loss by concentrated flow erosion at the end of the growing season. Cover crops with thick roots, such as Sinapis alba and Raphanus sativus subsp. oleiferus are less effective than cover crops with fine-branched roots such as Phacelia tanacetifoli, Lolium perenne (Ryegrass), Avena sativa (Oats) and Secale cereale (Rye) in preventing soil losses by concentrated flow erosion. These results enable soil managers to select the most suitable crops and maximize soil protection.

Section 304 of the 1990 clean air amendments (CAAA) directed the US occupational safety and health administration (OSFA) to develop a chemical process safety standard to protect workers on-site from accidents involving hazardous substances. OSHA issued 29 CFR 1910.119, process safety management of Highly hazardous chemicals (PSM) in 1992. Section 112 r of the CAAA further mandated that a standard be developed to protect the environment from accidental releases of hazardous substances. The US environmental protection agency (EPA) proposed such a standard in 1993 (58 Fr 54190) and revised their proposal in 1995). The final rule for risk management and accidental release prevention is more comprehensive and extensive than OSHA`s PSM standard. In this paper we will discuss the concepts of both programs, the classes of substances that would trigger a facility`s need for compliance and review the regulations for risk management.

In contrast to the construction of a new nuclear reactor, Retube/Refurbishment of nuclear reactors that have been in operation for many years will involve fabrication of a new core in a radiation environment. Careful planning of the radiation protection (RP) program is crucial to ensure the protection of workers and the environment, and the success of the projects. This paper describes the key RP activities currently underway in AECL's Retube/Refurbishment projects, covering RP during retubing tooling and system designs, retubing work planning, retubing operation, and waste transfer and management. The discussion will focus on RP initiatives from engineering design aspects of the projects. (author)

Energy, entropy, environment: Why is protection of the environment objectively difficult?

1995-05-01

Evolution and man`s history indicate that the winners are the species and societies that act faster and consume more high-quality energy and materials: in other words, those which cause more pollution and faster growth of entropy. This could be the reason why protection of the environment is objectively difficult and, in particular, why it is almost impossible to considerably reduce man`s consumption of energy and materials in a world of competition. To escape this fatal evolutionary outcome, fundamentally new thinking is needed, thinking which takes the survival of mankind as the primary value. The role of religion in solving this tremendously difficult task should not be neglected

Application of Advanced Materials Protecting from Influence of Free Space Environment

High cost and low availability of the components certified for use in the space environment forces satellite designers to using industrial and even commercial items. Risks associated with insufficient knowledge about behavior of these components in radiation environment are parried, mainly, by careful radiating designing of a satellite where application of special protective materials with improved space radiation shielding characteristics is one of the most widely used practices. Another advantage of protective materials application appears when a satellite designer needs using equipment in more severe space environment conditions then it has been provided at the equipment development. In such cases only expensive repeated qualification of the equipment hardness can be alternative to protective materials application. But mostly this way is unacceptable for satellite developers, being within strong financial and temporal restrictions. To apply protective materials effectively, the developer should have possibility to answer the question: "Where inside a satellite shall I place these materials and what shall be their shape to meet the requirements on space radiation hardness with minimal mass and volume expenses?" At that, the minimum set of requirements on space radiation hardness include: ionizing dose, nonionizing dose, single events, and internal charging. The standard calculative models and experimental techniques, now in use for space radiation hardness assurance of a satellite are unsuitable for the problem solving in such formulation. The sector analysis methodology, widely used in satellite radiating designing, is applicable only for aluminium shielding and doesn't allow taking into account advantages of protective materials. The programs simulating transport of space radiations through a substance with the use of Monte-Carlo technique, such as GEANT4, FLUKA, HZETRN and others, are fully applicable in view of their capabilities; but time required for

Turbine wheels of selected HPPs were replaced in the past , replacement of impellers of pumps of machines in PSP Cierny Vah started started at present and a complex modernization of our oldest HPP Ladce (1936) is planned aimed at an increase in absorption capacity of water turbines with an increase in their efficiency. The process of increasing the efficiency of the existing units without substantial construction changes in blocks of turbines gives also economic acceptability to the mentioned approaches from the point of view of both the gained installed capacity and electrical energy production compared to an option of building a modern HPP and it is also more acceptable from the point of view of environment protection than newly built HPPs. All of the technical changes, a process of increases of increasing the use of a hydroenergetic potential and also environment protection are being realized and will be realized only by high quality workers. Thus a program of transition to a more effective provision of activities with simultaneous increase in qualification and multipurpose use of labor force is a part of the equipment development program.

1984-04-01

US Environmental Protection Agency standards for the cleanup and disposal of inactive tailings sites require that control measures for disposal of tailings be designed to be effective for up to 1000 years if reasonably achievable, and, in any case, for 200 years at least. To control the escape of contaminants over such long periods, containment systems must be capable of adjusting to changing environmental conditions. Elements of a containment system include surface covers, biotic barriers, radon barriers, and, in some cases, liners. Each element of the system affects the others, and the whole system responds to the surrounding environment. Interaction is facilitated primarily by soil moisture. Consequently, the control of soil moisture is critical to the effectiveness of containment systems. Protective covers are necessary to prevent disruption of the containment system by physical or biological factors, to provide for the effective functioning of the radon barrier, and to prevent infiltration of excess water that could cause leaching. In order to design protective covers, a working knowledge of the factors and processes impacting tailings piles is required. This report characterizes the major factors and processes, and presents generic solutions based on current research. 65 references, 9 figures, 6 tables.

Purpose: Protection of bone marrow against radiotoxicity during radioimmunotherapy and in some cases external beam radiation therapy such as hemi-body irradiation would permit administration of significantly higher doses to tumors, resulting in increased efficacy and safety of treatment. Melanin, a naturally occurring pigment, possesses radioprotective properties. We hypothesized that melanin, which is insoluble, could be delivered to the bone marrow by intravenously administrated melanin-covered nanoparticles (MNs) because of the human body's 'self-sieving' ability, protecting it against ionizing radiation. Methods and Materials: The synthesis of MNs was performed via enzymatic polymerization of 3,4-dihydroxyphenylalanine and/or 5-S-cysteinyl-3,4-dihydroxyphenylalanine on the surface of 20-nm plain silica nanoparticles. The biodistribution of radiolabeled MNs in mice was done at 3 and 24 h. Healthy CD-1 mice (Charles River Laboratories International, Inc., Wilmington, MA) or melanoma tumor-bearing nude mice were given MNs intravenously, 50 mg/kg of body weight, 3 h before either whole-body exposure to 125 cGy or treatment with 1 mCi of 188 Re-labeled 6D2 melanin-binding antibody. Results: Polymerization of melanin precursors on the surface of silica nanoparticles resulted in formation of a 15-nm-thick melanin layer as confirmed by light scattering, transmission electron microscopy, and immunofluorescence. The biodistribution after intravenous administration showed than MN uptake in bone marrow was 0.3% and 0.2% of injected dose per gram at 3 and 24 h, respectively, whereas pre-injection with pluronic acid increased the uptake to 6% and 3% of injected dose per gram, respectively. Systemic MN administration reduced hematologic toxicity in mice treated with external radiation or radioimmunotherapy, whereas no tumor protection by MNs was observed. Conclusions: MNs or similar structures provide a novel approach to protection of bone marrow from ionizing radiation based

As a consequence of the 1982-1983 French Decentralization laws, local elected officials were entrusted with new responsibilities concerning environmental protection and local development. EDF, the French public electricity utility therefore had to respond to new demands. New forms of cooperation with the various local actors were imagined: assistance in diagnostics, working out local strategies, subcontracting and working for the establishment of new industrial plants, multi-purpose water management (dams for example), environment protection (discreet lines...), urban waste treatment, transportation, etc

Full Text Available This paper presents the benefits they can obtain business which aim to protect the environment. The environment protection has found its place and affects the process of systemic change of the Polish economy. This article assumes that building a competitive economy and enterprise development based on the principle of sustainable development requires the development of mechanisms for mutual benefits. These will be the economic mechanisms, technical and technological, and social. All these mechanisms are concentrated in clusters. Pursue sustainable development policies, an emphasis on environmental protection will be the general element for them a competitive advantage. Sustainable development will in this case be both the agent and the goal of economic and entrepreneurship development. Basing on the assumption that economic development is possible through the achievement of competitive advantage, sustainable development should be treated as its source.

The ecosystem approach (EA) involves considering the impacts of an anthropogenic stressor at the ecosystem level because this is usually the ultimate goal of environmental protection. As such, EA includes population, community and ecosystem effects, structural and functional effects, indirect effects due to ecological interactions between species, dynamic interactions, positive or negative feedback loops, and potential synergistic or antagonistic effects of multiple stressors (both anthropogenic and natural). All such effects better reflect the reality of the impact of a contamination scenario than if assessments are restricted to considering effects to individual organisms or species. Such effects may be greater or lesser than expected from studies of individual organisms or species, so not considering them may result in under- or overestimation of risk, respectively. EA is a term that is widely used in environmental assessment, management and legislation in a number of regulatory fields (e.g., radiation protection, chemicals legislation, fisheries policy, international biodiversity conventions). However, although its justification is now well established in a wide range of environment protection contexts, its practical use is still unclear due to poorly defined protection goals and assessment endpoints, making its implementation difficult. This paper presents the initial findings of a newly formed follow-up task group of the International Union of Radioecology whose aims are to identify ways to put the EA into practice when considering protection of the environment from radiation. Drawing on knowledge and experience from a range of fields, we summarise the types of ecosystem processes, goods and services that might be included when using this approach, the science that supports the use of the EA, and the methodological challenges that need to be addressed when implementing the EA in the field of radiation protection.

2009-09-01

Full Text Available The right to environment is a recognised human right in Africa. However, despite the legal and institutional frameworks designed to respect, promote, protect and fulfil the right, its enjoyment is still a mirage to majority of African citizens as a result of environmental degradation. This article aims to proffer a holistic or integrated approach to tackling the problem of environmental degradation in sub-Saharan Africa in order to enhance the protection of the environment and the realisation of this right in the region. It recognises that the problem of environmental degradation in the region is not due to lack of regulatory frameworks, but rather due to other factors that are mainly socio-economic and political in nature. It argues that to enhance the protection of the environment and realisation of this right in sub-Saharan Africa, African governments must adopt a holistic approach towards the protection of the environment, and proposes the promotion of good governance and socio-economic reform in the region as an integral core of such approach.

Evapotranspiration (ET) covers.

Evapotranspiration (ET) cover systems are increasingly being used at municipal solid waste (MSW) landfills, hazardous waste landfills, at industrial monofills, and at mine sites. Conventional cover systems use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the surface to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on soil to capture and store precipitation until it is either transpired through vegetation or evaporated from the soil surface. Compared to conventional membrane or compacted clay cover systems, ET cover systems are expected to cost less to construct. They are often aesthetic because they employ naturalized vegetation, require less maintenance once the vegetative system is established, including eliminating mowing, and may require fewer repairs than a barrier system. All cover systems should consider the goals of the cover in terms of protectiveness, including the pathways of risk from contained material, the lifecycle of the containment system. The containment system needs to be protective of direct contact of people and animals with the waste, prevent surface and groundwater water pollution, and minimize release of airborne contaminants. While most containment strategies have been based on the dry tomb strategy of keeping waste dry, there are some sites where adding or allowing moisture to help decompose organic waste is the current plan. ET covers may work well in places where complete exclusion of precipitation is not needed. The U.S. EPA Alternative Cover Assessment Program (ACAP), USDOE, the Nuclear Regulatory Commission, and others have researched ET cover design and efficacy, including the history of their use, general considerations in their design, performance, monitoring, cost, current status, limitations on their use, and project specific examples.

Two articles of 'Care of coppice in Wood Totoro' and 'Global environment protection from the universe' are included in this report. The former explains the necessity of coppice conservation through an example of Sayama Hill in Tokyo. Until the time 30 years ago, coppices are deeply related to people as the places which supply fuel and fertilizer to villagers, but they have been left or cut down by energy source conversion and development of home lots. Now we must learn the traditional methods of caring coppices again and find a new sense of values regarding the nature. The latter introduces satellite-used remote sensing which allows to continuously scan all the areas of the earth within a short period for global environment protection. This sensor uses a wide range of wavelengths from light to radiowave. In the U.S., it is operated in the name of LANDSAT since 1972, and Japan is also operating various kinds of satellites for environment research concerning, e.g., CO2 concentration and resource exploration. 10 figs.

Ongoing climate change may undermine the effectiveness of protected area networks in preserving the set of biotic components and ecological processes they harbor, thereby jeopardizing their conservation capacity into the future. Metrics of climate change, particularly rates and spatial patterns of climatic alteration, can help assess potential threats. Here, we perform a continent-wide climate change vulnerability assessment whereby we compare the baseline climate of the protected area network in North America (Canada, United States, México-NAM) to the projected end-of-century climate (2071-2100). We estimated the projected pace at which climatic conditions may redistribute across NAM (i.e., climate velocity), and identified future nearest climate analogs to quantify patterns of climate relocation within, among, and outside protected areas. Also, we interpret climatic relocation patterns in terms of associated land-cover types. Our analysis suggests that the conservation capacity of the NAM protection network is likely to be severely compromised by a changing climate. The majority of protected areas (~80%) might be exposed to high rates of climate displacement that could promote important shifts in species abundance or distribution. A small fraction of protected areas (climates that represent analogs of conditions currently characterizing almost a fifth of the protected areas across NAM. However, the majority of nearest climatic analogs for protected areas are in nonprotected locations. Therefore, unprotected landscapes could pose additional threats, beyond climate forcing itself, as sensitive biota may have to migrate farther than what is prescribed by the climate velocity to reach a protected area destination. To mitigate future threats to the conservation capacity of the NAM protected area network, conservation plans will need to capitalize on opportunities provided by the existing availability of natural land-cover types outside the current network of NAM

Radiological and environmental protection experience associated with the reactor cover gas processing system at the Fast Flux Test Facility (FFTF) has been excellent. Personnel radiation exposures received from operating and maintaining the reactor cover gas processing system have been very low, the system has remained free of radioactive particulate contamination through the first seven operating cycles (cesium contamination was detected at the end of Cycle 8A), and releases of radioactivity to the environment have been very low, well below environmental standards. This report discusses these three aspects of fast reactor cover gas purification over the first eight operating cycles of the FFTF (a duration of a little more than four years, from April 1982 through July 1986)

NONE

2004-07-01

The marine environment of the North Sea and Baltic Sea is still heavily polluted. The marine ecosystems are under severe stress from overfishing, water pollution, raw materials production and tourism. Environmental protection in this region necessitates decisive political initiatives and strict corrections especially in fishery policy, agricultural policy and chemical substances control. This is the balance of the special expert opinion of the Council of Environmental Experts. The publication specifies the main problem areas, the current pollution situation, the fields where action is most urgently required - especially in fishery, chemical substances, agricultural and sea travel policies - and presents suggestions for an integrated European and national marine protection policy including a regional development concept for the marine environment.

Evidence-based political measures need reliable information about the health status of a population and the determinants affecting health. Here, environment and health indicators can provide helpful additional insights. This article provides an overview of existing indicators in the field of environment and health. There are single indicators and indicator sets describing solely the environment or health as well as some indicators integrating both aspects. The indicator sets cover classical epidemiological indicators but also summary measures of population health, which combine mortality and morbidity as well as simple descriptions of the exposure towards environmental risks. The indicator sets mostly cover water and air quality related aspects. For some of the indicators their influence on health is also presented. Furthermore, environment related health indicators are part of sustainability indicator sets. There are indicators on the international, European, national, and municipal level. All indicator sets aim to support policy-making by advising on measures and setting priorities in the area of environment and health protection. However not all indicators reflect the effect of the environment on health adequately. Therefore, further development of the existing indicators is necessary to reflect current progress (e. g. political needs) and to include new scientific evidence in the field of environment and health. A continuous provision, review, and interpretation of meaningful indicators is required to identify trends and to react to these in order to protect the environment and health. This is necessary to adequately pursue the precautionary principle.

Nest covering in plovers: How modifying the visual environment influences egg camouflage.

2016-10-01

Camouflage is one of the most widespread antipredator defences, and its mechanistic basis has attracted considerable interest in recent years. The effectiveness of camouflage depends on the interaction between an animal's appearance and its background. Concealment can therefore be improved by changes to an animal's own appearance, by behaviorally selecting an optimal background, or by modifying the background to better match the animal's own appearance. Research to date has largely focussed on the first of these mechanisms, whereas there has been little work on the second and almost none on the third. Even though a number of animal species may potentially modify their environment to improve individual-specific camouflage, this has rarely if ever been quantitatively investigated, or its adaptive value tested. Kittlitz's plovers (Charadrius pecuarius) use material (stones and vegetation) to cover their nests when predators approach, providing concealment that is independent of the inflexible appearance of the adult or eggs, and that can be adjusted to suit the local surrounding background. We used digital imaging and predator vision modeling to investigate the camouflage properties of covered nests, and whether their camouflage affected their survival. The plovers' nest-covering materials were consistent with a trade-off between selecting materials that matched the color of the eggs, while resulting in poorer nest pattern and contrast matching to the nest surroundings. Alternatively, the systematic use of materials with high-contrast and small-pattern grain sizes could reflect a deliberate disruptive coloration strategy, whereby high-contrast material breaks up the telltale outline of the clutch. No camouflage variables predicted nest survival. Our study highlights the potential for camouflage to be enhanced by background modification. This provides a flexible system for modifying an animal's conspicuousness, to which the main limitation may be the available

Full Text Available Interrelationships between soil cover and plant cover of normally developed (or postlithogenic mineral soils are analysed on the basis of four sampling soil groups. The four-link pedo-ecological sequence of analysed soils, rendzinas → brown soils → pseudopodzolic soils → gley-podzols, forms a representative cross section in relation to the normal mineral soils of Estonia. All groups differ substantially from each other in terms of soil properties (calcareousness, acidity, nutrition conditions, profile fabric and humus cover. The primary tasks of the research were (1 to elucidate the main pedo-ecological characteristics of the four soil groups and their suitability for plant cover, (2 to evaluate comparatively soils in terms of productivity, sustainability, biodiversity and environmental protection ability and (3 to analyse possibilities for ecologically sound matching of soil cover with suitable plant cover. On the basis of the same material, the influence of land-use change on humus cover (epipedon fabric, properties of the entire soil cover and soil–plant interrelationship were also analysed. An ecosystem approach enables us to observe particularities caused by specific properties of a soil type (species, variety in biological turnover and in the formation of biodiversity.

Measures for protection of the environment and the breach of a foreign investor's rights

Directory of Open Access Journals (Sweden)

Đundić Petar

2011-01-01

Full Text Available The paper analyses the relationship between state measures aimed at protecting the environment and the so-called regulative expropriation of investment. Protection of the environment has established itself as a legitimate regulative purpose in legal doctrine and in a number of sources of international foreign investment law. In the analytical framework of police powers doctrine it would suggest that state measures taken for environmental reasons, even if they are harmful for the economic interests of foreign investor, cannot be considered regulative expropriation. However, arbitral practice shows more restrictive approach towards regulative freedom of states in this area. The right of state to regulate without imposition of a duty to compensate a foreign investor for his loss is not unconditionally accepted. The regulative measure must be taken in good faith, i.e. with the true purpose of protecting the environment and nondiscriminatory in its character. Furthermore, there is a tendency in arbitral practice that the legitimate regulative purpose of state measure is weighed against other factors such as legitimate expectations of a foreign investor and the level of his economic loss in order to determine whether the expropriation has occurred.

Measuring protected-area isolation and correlations of isolation with land-use intensity and protection status.

2012-08-01

Protected areas cover over 12% of the terrestrial surface of Earth, and yet many fail to protect species and ecological processes as originally envisioned. Results of recent studies suggest that a critical reason for this failure is an increasing contrast between the protected lands and the surrounding matrix of often highly altered land cover. We measured the isolation of 114 protected areas distributed worldwide by comparing vegetation-cover heterogeneity inside protected areas with heterogeneity outside the protected areas. We quantified heterogeneity as the contagion of greenness on the basis of NDVI (normalized difference vegetation index) values, for which a higher value of contagion indicates less heterogeneous land cover. We then measured isolation as the difference between mean contagion inside the protected area and mean contagion in 3 buffer areas of increasing distance from the protected-area border. The isolation of protected areas was significantly positive in 110 of the 114 areas, indicating that vegetation cover was consistently more heterogeneous 10-20 km outside protected areas than inside their borders. Unlike previous researchers, we found that protected areas in which low levels of human activity are allowed were more isolated than areas in which high levels are allowed. Our method is a novel way to assess the isolation of protected areas in different environmental contexts and regions. ©2011 Society for Conservation Biology.

Fire is an important disturbance agent in Myanmar impacting several ecosystems. In this study, we quantify the factors impacting vegetation fires in protected and non-protected areas of Myanmar. Satellite datasets in conjunction with biophysical and anthropogenic factors were used in a spatial framework to map the causative factors of fires. Specifically, we used the frequency ratio method to assess the contribution of each causative factor to overall fire susceptibility at a 1km scale. Results suggested the mean fire density in non-protected areas was two times higher than the protected areas. Fire-land cover partition analysis suggested dominant fire occurrences in the savannas (protected areas) and woody savannas (non-protected areas). The five major fire causative factors in protected areas in descending order include population density, land cover, tree cover percent, travel time from nearest city and temperature. In contrast, the causative factors in non-protected areas were population density, tree cover percent, travel time from nearest city, temperature and elevation. The fire susceptibility analysis showed distinct spatial patterns with central Myanmar as a hot spot of vegetation fires. Results from propensity score matching suggested that forests within protected areas have 11% less fires than non-protected areas. Overall, our results identify important causative factors of fire useful to address broad scale fire risk concerns at a landscape scale in Myanmar. PMID:25909632

Fire-land cover partition analysis suggested dominant fire occurrences in the savannas (protected areas and woody savannas (non-protected areas. The five major fire causative factors in protected areas in descending order include population density, land cover, tree cover percent, travel time from nearest city and temperature. In contrast, the causative factors in non-protected areas were population density, tree cover percent, travel time from nearest city, temperature and elevation. The fire susceptibility analysis showed distinct spatial patterns with central Myanmar as a hot spot of vegetation fires. Results from propensity score matching suggested that forests within protected areas have 11% less fires than non-protected areas. Overall, our results identify important causative factors of fire useful to address broad scale fire risk concerns at a landscape scale in Myanmar.

Fire is an important disturbance agent in Myanmar impacting several ecosystems. In this study, we quantify the factors impacting vegetation fires in protected and non-protected areas of Myanmar. Satellite datasets in conjunction with biophysical and anthropogenic factors were used in a spatial framework to map the causative factors of fires. Specifically, we used the frequency ratio method to assess the contribution of each causative factor to overall fire susceptibility at a 1km scale. Results suggested the mean fire density in non-protected areas was two times higher than the protected areas. Fire-land cover partition analysis suggested dominant fire occurrences in the savannas (protected areas) and woody savannas (non-protected areas). The five major fire causative factors in protected areas in descending order include population density, land cover, tree cover percent, travel time from nearest city and temperature. In contrast, the causative factors in non-protected areas were population density, tree cover percent, travel time from nearest city, temperature and elevation. The fire susceptibility analysis showed distinct spatial patterns with central Myanmar as a hot spot of vegetation fires. Results from propensity score matching suggested that forests within protected areas have 11% less fires than non-protected areas.

Overlapping Leaves Covering Flowers in the Alpine Species Eriophyton wallichii (Lamiaceae: Key Driving Factors and Their Potential Impact on Pollination.

Directory of Open Access Journals (Sweden)

De-Li Peng

Full Text Available Extrafloral structures are supposed to have evolved to protect flowers from harsh physical environments but might have effects on pollination. Overlapping leaves cover flowers in Eriophyton wallichii, an alpine perennial endemic to the Himalaya-Hengduan Mountains. In previous study, it has showed that these extrafloral leaves can protect interior flowers from temperature fluctuations caused by drastic solar radiation fluctuations, but these leaves may also protect interior flowers from rain wash and UVB damage, and we do not know which one is the main function. In this study, we investigated whether rain and UVB protection are the main functions of overlapping leaves covering flowers and their potential impact on pollination. We first measured the intensities of UVB radiation in open air, beneath leaves and corollas, and then examined pollen susceptibility to different intensities of UVB and rain in the laboratory to estimate whether corollas per se protect interior pollen from UVB and rain damage. We also carried out pollination treatments and observed pollinator visitation of flowers with and without leaves in the field to assess whether the overlapping leaves covering flowers impair pollinator attraction. Our results showed that (1 water and strong UVB significantly decreased pollen germinability, but corollas per se could protect pollen from UVB and rain damage; (2 no autonomous self-pollination and apomixis occurred, and pollinators were essential for the reproduction of E. wallichii; however, flower coverage by overlapping leaves did not limit pollination. We suggested that rain and UVB protection was not the main function of overlapping leaves covered flowers, given that this protection can be provided by corollas per se. Alternatively, this extrafloral structure in E. wallichii may have evolved in response to extreme high temperatures associated with the strong solar radiation fluctuations. This indicates that, even in alpine plants

The requirement for assessments of the environmental effects of radiation, i.e. effects on non-human biota, is increasing due to growing public concern for environmental protection issues and integration of environmental impact assessments into the regulatory process. Thus, there is a strong need to establish a framework for the assessment of environmental impact of ionising radiation, as well as a system for protection of the environment from ionising radiation. These ambitions are reflected in a number of international efforts and various 'systems' have been proposed or are under development. This paper considers the current discussions on environmental protection within the International Commission on Radiological Protection (ICRP), as part of the Commission's ongoing revision of its recommendations as laid out in Publication 60. Furthermore, the paper reviews work within the EC-funded FASSET (Framework for ASSessment of Environmental impacT) project. The concepts developed both by ICRP and FASSET are similar, and the FASSET approach and results may illustrate how forthcoming ICRP recommendations could be turned into practical application.

We used forty-four primiparous sows housed in large individual pens from approximately 2 weeks prior to expected parturition. The sows were...... and the temporal pattern of sow position in relation to position of the cover (left or right side of the pen) was studied. Furthermore, postural and nest-building behaviours were observed, as well as situations where the piglets were either at risk of being crushed or were crushed. The results showed......In semi-natural environments sows often select a protected nest site at farrowing. Investigations of nest site selection under indoor conditions are scarce but suggest that sows prefer to nest and farrow under a covered area. Since feed-back from a functional nest may improve maternal behaviour...

In Central America, palm swamps are known collectively as yolillales. These wetlands are usually dominated by the raffia palm Raphia taedigera, but also by the royal palm Manicaria saccifera and -in lower extensions- by the American oil palm Elaeis oleifera. The yolillales tend to be poor in woody species and are characteristic of regions with high rainfall and extensive hydroperiods, so they remain flooded most of the year. The dominance of large raffia palm leaves in the canopy, allow these environments to be distinguishable in aerial photographs, which consequently has helped to map them along most of their distribution. However, while maps depicting yolillales are available, the extent of their surface area, perimeter and connectivity remains poorly understood. This is particularly true for yolillales in Costa Rica and Nicaragua, countries that share a good proportion of palm dominated swaps in the Rio San Juan Basin. In addition, it is not known the actual area of these environments that is under any category of protection according to the conservation systems of both countries. As a first step to catalog yolillal wetlands in Costa Rica and Nicaragua, this paper evaluates cartographic maps to delineate yolillales in the region. A subsample of yolillales mapped in this study were visited and we geo-referenced them and evaluate the extent and condition of the swamp. A total of 110 883.2ha are classified as yolillales in Nicaragua, equivalent to 22% of wetland surface area recorded for that country (excluding the Cocibolca and Xolothn Lakes). In Costa Rica, 53 931.3ha are covered by these palm dominated swamps, which represent 16.24% of the total surface area covered by wetlands. About 47% of the area covered by yolillales in Nicaragua is under some category of protection, the largest extensions protected by Cerro Silva, Laguna Tale Sulumas and Indio Maiz Nature Reserves. In Costa Rica, 55.5% of the area covered by yolillal is located within protected areas

Estimatation of evapotranspiration and crop coefficient of melon cultivated in protected environment

Directory of Open Access Journals (Sweden)

Cláudia S. Lozano

Full Text Available ABSTRACT The objective of this work was to determine the water consumption and the crop coefficient of melon in a protected environment. The experiment was conducted in a greenhouse at the Technical Center of Irrigation of the State University of Maringá, in Maringá, PR. The melon hybrid used was Sunrise and the irrigations were performed daily by drip irrigation. Crop water requirement was quantified based on its evapotranspiration directly measured through constant water table lysimeters. Weather information was collected in an automatic weather station, installed inside the protected environment, which allowed to calculate the reference evapotranspiration by the Penman-Monteith method. The total water consumption of the melon crop was 295 mm, reaching maximum crop evapotranspiration of 5.16 mm d-1. The phenological stages were shorter in the initial, growth and intermediate phases, compared with the data from FAO. The determined crop coefficients were 0.87, 1.15 and 0.64 for the initial, intermediate and final stages, respectively

MLI blankets for the Space Station Freedom (SSF) must comply with general program requirements and recommendations for long life and durability in the low-Earth orbit (LEO) environment. Atomic oxygen and solar ultraviolet/vacuum ultraviolet are the most important factors in the SSF natural environment which affect materials life. Two types of Beta cloth (Teflon coated woven glass fabric), which had been proposed as MLI blanket covers, were tested for long-term durability in the LEO environment. General resistance to atomic oxygen attack and permeation were evaluated in the high velocity atomic oxygen beam system at Los Alamos National Laboratories. Long-term exposure to the LEO environment was simulated in the laboratory using a radio frequency oxygen plasma asher. The plasma asher treated Beta cloth specimens were tested for thermo-optical properties and mechanical durability. Space exposure data from the Long Duration Exposure Facility and the Intelsat Solar Array Coupon were also used in the durability assessment. Beta cloth fabricated to Rockwell specification MBO 135-027 (Chemglas 250) was shown to have acceptable durability for general use as an MLI blanket cover material in the LEO environment while Sheldahl G414500 should be used only in locations which are protected from direct Ram atomic oxygen

Exploiting coalbed methane and protecting the global environment

The global climate change caused by greenhouse gases (GHGs) emission has received wide attention from all countries in the world. Global environmental protection as a common problem has confronted the human being. As a main component of coalbed methane, methane is an important factor influencing the production safety of coal mine and threatens the lives of miners. The recent research on environment science shows that methane is a very harmful GHG. Although methane gas has very little proportion in the GHGs emission and its stayed period is also very short, it has very obvious impact on the climate change. From the estimation, methane emission in the coal-mining process is only 10% of the total emission from human`s activities. As a clean energy, Methane has mature recovery technique before, during and after the process of mining. Thus, coalbed methane is the sole GHG generated in the human`s activities and being possible to be reclaimed and utilized. Compared with the global greenhouse effect of other GHGs emission abatement, coalbed methane emission abatement can be done in very low cost with many other benefits: (1) to protect global environment; (2) to improve obviously the safety of coal mine; and (3) to obtain a new kind of clean energy. Coal is the main energy in China, and coalbed contains very rich methane. According to the exploration result in recent years, about 30000{approximately}35000 billion m{sup 2} methane is contained in the coalbed below 2000 m in depth. China has formed a good development base in the field of reclamation and utilization of coalbed methane. The author hopes that wider international technical exchange and cooperation in the field will be carried out.

Securing a better future for all: Nuclear techniques for global development and environmental protection. NA factsheet on environment laboratories: Protecting the environment

International Nuclear Information System (INIS)

2012-01-01

According to the Millennium Development Goals, managing the environment is considered an integral part of the global development process. The main purpose of the IAEA's environment laboratories is to provide Member States with reliable information on environmental issues and facilitate decision making on protection of the environment. An increasingly important feature of this work is to assess the impact of climate change on environmental sustainability and natural resources. The IAEA's environment laboratories use nuclear techniques, radionuclides, isotopic tracers and stable isotopes to gain a better understanding of the various marine processes, including locating the sources of pollutants and their fate, their transport pathways and their ultimate accumulation in sediments. Radioisotopes are also used to study bioaccumulation in organisms and the food chain, as well as to track signals of climate change throughout history. Natural and artificial radionuclides are used to track ocean currents in key regions. They are also used to validate models designed to predict the future impact of climate change and ocean acidification. The laboratories study the fate and impact of contamination on a variety of ecosystems in order to provide effective preventative diagnostic and remediation strategies. They enhance the capability of Member States to use nuclear techniques to understand and assess changes in their own terrestrial and atmospheric environments, and adopt suitable and sustainable remediation measures when needed. Since 1995, the IAEA environment laboratories have coordinated the international network of Analytical Laboratories for the Measurement of Environmental Radioactivity, providing accurate analysis in the event of an accident or an intentional release of radioactivity. In addition, the laboratories work alongside other organizations, such as UNESCO, the IOC, UNEP and the EC. The laboratories collaborate with Member States through direct involvement with

Full Text Available Construction investments are related to the economic development of each country. Expansion of towns and settlements, construction, industrial, commercial and recreational objects and the communication network is necessary and results from regional development strategies. For their implementation it is necessary to prepare the area designated for their development. In many regions of our country area suitable for construction are increasingly limited, and furthermore investors often looks for an attractive investment location. For this reason, more and more construction projects dangerously close to areas of high natural value and protected and often are entering the these areas. To minimize the negative investment impact on the environment there are developed several variants of investment. Next, assessing the positive and negative effects, we choose the best, from the point of view of the surrounding environment solution. To illustrate the procedure example of analysis using the method proposed by the author, the indicator is shown.

Muzongomerwa, A.

2014-04-01

Ionizing radiation including the use of nuclear gauges can be very hazardous to humans and steps must be taken to minimize the risks so as to prevent deterministic effects and limiting chances for stochastic effects. The availability of a Radiation Protection Programme and its effective implementation ensures appropriate safety and security provisions for sealed radiation sources and promotes a safety culture within a facility that utilizes these sources. This study aims at establishing a guide on the radiation protection programme in nuclear gauges that comply with national requirements derived from current international recommendations. Elements that form part of a radiation protection programme are covered in detail as well as recommendations. The overall objective is to protect people (operators and the public) and the environment from the harmful effects of these sources if they are not properly controlled. Nuclear gauges for well logging and X-ray based gauges are outside the scope of this study. (au)

According to the overall requirements of ecological construction and environmental protection, rely on the national key ecological engineering, strengthen ecological environmental restoration and protection, improve forest cover, control soil erosion, construct important ecological security barrier in poor areas, inhibit poverty alleviation through ecological security in this area from environmental damage to the vicious cycle of poverty. Obviously, the dynamic monitoring of ecological security in contiguous destitute areas of Sichuan province has a policy sense of urgency and practical significance. This paper adopts RS technology and GIS technology to select the Luhe region of Jinchuan county and Ganzi prefecture as the research area, combined with the characteristics of ecological environment in poor areas, the impact factors of ecological environment are determined as land use type, terrain slope, vegetation cover, surface water, soil moisture and other factors. Using the ecological environmental safety assessment model, the ecological environment safety index is calculated. According to the index, the ecological environment safety of the research area is divided into four levels. The ecological environment safety classification map of 1990 in 2009 is obtained. It can be seen that with the human modern life and improve their economic level, the surrounding environment will be destroyed, because the research area ecological environment is now in good, the ecological environment generally tends to be stable. We should keep its ecological security good and improve local economic income. The relationship between ecological environmental security and economic coordinated development in poor areas has very important strategic significance.

With the development of new basic safety standards for the protection against the dangers arising from ionising radiation, foreseen in Article 2 and Article 30 of the Euratom Treaty, the European Commission modernises and consolidates the European radiation protection legislation. The new Directive offers in a single coherent document, basics safety standards for radiation protection which take account of the status-quo of science and technology, cover all relevant radiation sources, including natural radiation sources, integrate protection of workers, members of the public, patients and the environment, cover all exposure situations, planned, existing, emergency, and harmonise numerical values with international standards. After having received very positive opinions of the Article 31 Group of Experts and the European Economic and Social Committee, the proposed Directive has reached agreement in the Working Party on Atomic Questions of the European Council (WPAQ). The Opinion of the European Parliament is expected in September 2013, which would allow a publication of the Directive in the Official Journal of the European Union by the end of 2013. (orig.)

Full Text Available The importance of a shift toward agricultural systems, which are more complex in terms of biodiversity in emerging countries such as China, where most of the population (about 60% lives in rural areas, in poor conditions and still relies on agriculture as the main source of income, is discussed. In China the problems caused by shifting to more intensive and polluting agricultural production patterns to address the demand for food of the growing population and by the need of higher incomes of rural communities are serious. The experience gained in the framework of the Sino-Italian Cooperation Program for Environment Protection jointly launched by the Italian Ministry for the Environment and Territory (IMET and the State Environment Protection Administration of China (SEPA in the year 2000, through the implementation of several cooperation projects in different rural areas of China is critically discussed.

Mutual Impacts of Geocaching and Natural Environment

Full Text Available Rising popularity of geocaching is linked to increased risk of negative impacts on natural environment. Based on that, this paper intends to present possible approach of how to evaluate these impacts in the Landscape protected area Moravian Karst (Czech Republic and in the Vrátna dolina valley (National park Malá Fatra, Slovak Republic. Recreation along with nature conservation has been solved in these areas in the log-run and geocaching has been steadily extending offer of recreational activities. Therefore, it seems desirable to examine how geocaching affects environment and simultaneously how topography or land cover influences availability or difficulty of caches. 57 caches (i.e. one third of the total has been analyzed in the Moravian Karst and 11 caches in the Vrátna dolina valley. To assess impacts, own classification of indicators has been suggested, such as cache attendance, environment attractiveness or visually detected impacts of geocaching on natural environment. Our study revealed the major risk lies primarily in geo-highways which – with respect to soil type, land cover and intensity of cache attendance – grow rather fast. Despite the local nature of detected impacts, an increased attention shall be devoted to environment care and specifically to regulation of attendance.

Optimum combination of water drainage,water supply and eco-environment protection in coal-accumulated basin of North China

2000-01-01

The conflict among water drainage,water supply and eco-environment protection is getting more and more serious due to the irrational drainage and exploitation of ground water resources in coal-accumulated basins of North China.Efficient solutions to the conflict are to maintain long-term dynamic balance between input and output of the ground water basins,and to try to improve resourcification of the mine water.All solutions must guarantee the eco-environment quality.This paper presents a new idea of optimum combination of water drainage,water supply and eco-environment protection so as to solve the problem of unstable mine water supply,which is caused by the changeable water drainage for the whole combination system.Both the management of hydraulic techniques and constraints in economy,society,ecology,environment,industrial structural adjustments and sustainable developments have been taken into account.Since the traditional and separate management of different departments of water drainage,water supply and eco-environment protection is broken up,these departments work together to avoid repeated geological survey and specific evaluation calculations so that large amount of national investment can be saved and precise calculation for the whole system can be obtained.In the light of the conflict of water drainage,water supply and eco-environment protection in a typical sector in Jiaozuo coal mine,a case study puts forward an optimum combination scheme,in which a maximum economic benefit objective is constrained by multiple factors.The scheme provides a very important scientific base for finding a sustainable development strategy.

Under strong social pressure driven by current environmental concerns, all environmentalists are called to construct scientific knowledge, concepts and principles suitable to ensure acceptable mastering of ecological risk. Environment Protection against radioactivity is certainly the new challenge for radioecology. Originally, radioecology has evolved with the primary goal of assessing the impact of radioactivity on man, and as such, was focused on transfer to man through the environment. Now, following a trend that is already underway for other toxicants, the environment itself is also considered as a target requiring protection. As compared to the past, this new focus of radioecology is even more 'science demanding' particularly for basic understanding in biology and ecology. In addition to the knowledge on acute effects of high doses of radioactivity on small human critical groups, it is needed to know what happens to large ecosystems when loaded with small, but long-lasting, amounts of radio-toxicants. In addition to simple direct transfer, it is needed to take into account complex interaction processes and cycling that may lead to the redistribution of radionuclides, and eventually to their bioconcentration. In addition to classical situations like external irradiation, inhalation and wounding, it is necessary to study more thoroughly the effects of internal contamination following trophic chains. In addition to the most studied physical transfer and dispersion phenomena, it is mandatory to clarify how the many differentiating processes at work in the biosphere are acting on bioavailability, a feature that is overlooked in the current homogeneous approach of simplistic models. For all these reasons, today radioecology has to deepen its roots in the main stream of environment protection and the most advanced, or actively evolving, associated set of sciences.

SUBSTANTIATING THE DEVELOPMENT STRATEGIES FOR TOURISM IN PROTECTED AREAS

2013-12-01

Full Text Available The protected natural areas, irrespective of their classification modality or the motivations they propose, have become more and more attractive for tourists. However, in time, the increasing touristic flows they attract, often developed in an uncontrolled manner, lead to the erosion of the space and the degradation of ecosystems. Developing tourism on sustainable principles, with the appropriate balance of the two functions of a protected area – the scientific and the touristic function – should start from the analysis of this form of tourism and of the development opportunities and limits regarded from the perspective of the external environment, and from the particularisation of the concept “site’s tourist reception capacity”. Destination areas should meet the economic, social and ecological requirements in competition, so that they observe the integrity of natural resources and of local communities. The upper limit of the number of visits allowed in a protected area is purposefully set at a level below the identified level of accepted use, so that, in the long run, the environment could be able to cover the possible increases occurred in the number of tourists, without subjecting the environment to further harm.

Adriano Stephan Nascente

Full Text Available ABSTRACT Besides providing benefits to the environment such as soil protection, release of nutrients, soil moisture maintenance, and weed control, cover crops can increase food production for grain production. The aim of this study was to evaluate the production of biomass and grain cover crops (and its respective effects on soil chemical and physical attributes, yield components, and grain yield of rice in Mozambique. The study was conducted in two sites located in the province of Cabo Delgado, in Mozambique. The experimental design was a randomized block in a 2 × 6 factorial, with four repetitions. Treatments were carried out in two locations (Cuaia and Nambaua with six cover crops: Millet (Pennisetum glaucum L.; namarra bean (Lablab purpureus (L. Sweet, velvet beans (Mucuna pruriens L., oloco beans (Vigna radiata (L. R. Wilczek, cowpea (Vigna unguiculata L., and fallow. Cover crops provided similar changes in chemical and physical properties of the soil. Lablab purpureus, Vigna unguiculata, and Mucuna pruriens produced the highest dry matter biomass. Vigna unguiculada produced the highest amount of grains. Rice grain yields were similar under all cover crops and higher in Cuaia than Nambaua.

Protection of Microkernel Environment L4Re from Stack-smashed Attacks

Directory of Open Access Journals (Sweden)

Vasily Andreevich Sartakov

2014-12-01

Full Text Available Microkernel-based operating systems provide high level of protection due to the strong isolation of components, small size of Trusted Computing Base and execution of drivers in user space. At the same time, such systems are vulnerable to a stack overflow attacks, because these attacks exploit the hardware features of the platform, such as shared memory space for data and code. Modern architectures, such as AMD64 and ARM, provide opportunities to counteract attacks at the hardware level by disallowing memory allocation for storing executable stack and heap, but this protection mechanism requires additional support from the operating system. This paper presents memory management, program execution model and IPC mechanism of microkernel Fiasco.OC and environment L4Re from nonexecution memory support point of view.

Environmental protection: Shifting the focus toward the protected object

Cvetić Radenka

2013-01-01

Full Text Available This article is an attempt to provide a comprehensive overview of the rationale which led to developments in the law of environmental protection in a direction of an even more efficient protection of environment from human beings. There has been a transformation of the constitutionally protected right to a healthy environment to the Constitutional guarantee which involves both duty and responsibility for its protection. There has also been a shift from declaratory protection toward enforceable prohibitions and orders. These transformations have occurred when the society faced, under dramatic circumstances, the situation which shows that failure to protect the common good could lead to catastrophic consequences. The system of environmental protection, which enables sustainable development, is based on the primacy of the precautionary principle which deals with prevention and reduction of probability of harm, as well as on the no fault liability of the polluter for the environmental harm even in the absence of the claim for damages. The efficacy of the environmental protection could be improved by raising the awareness of the preservation of environment. The understanding that the protection of environment amounts to a survival of a mankind could lead to creating rights for the environment as such.

Protection of the environment. How to position radioprotection in an ecological risk assessment perspective

International Nuclear Information System (INIS)

Brechignac, Francois

2003-01-01

The development of a system capable of ensuring adequate protection of the environment from the harmful effects of ionising radiation is at present particularly debated. This need comes both from a restrictive consideration of the environment in the so far existing system for human radioprotection, and the planetary-wide growing concerns about man's technogenic influence on his environment which have yielded 'sustainability' and 'precaution' as guiding principles for environmental protection. Whilst evolving from the field of human radioprotection, the radioprotection of the environment needs to be discussed in a wider perspective, with particular emphasis on the most advanced concepts which emerge from the efforts to deriving improved approaches to Ecological Risk Assessment. For the sake of protection, the environment is traditionally addressed through its biota since these are the sensitive components of ecosystems. Similarities between man and biotas reflect the ubiquitous mechanistic effects of radiation on life which disrupt molecules. However, important differences also arise in a number of perspectives, from the large spectrum of different species of biotas to their hierarchical self-organisation as interacting populations within ecosystems. Altogether, these aspects are prone to promote complex arrays of different responses to stress which lie beyond the scope of human radioprotection due to its focus on individuals of a single species. By means of selected illustrations, this paper reviews and discusses the current challenges faced in proper identification of measurable effect endpoints (stochastic/deterministic, individual/population- or ecosystem-relevant), dose limits in chronic exposure (or levels of concern), and their consideration according to radiation type (RBE) and interactions with other contaminants (synergies/antagonisms) which represent critical gaps in knowledge. The system of human radioprotection has conceptually been targeted at limiting

An approach to the new ICRP recommendations on protection of the environment for the control of radioactive discharges

International Nuclear Information System (INIS)

Telleria, Diego

2008-01-01

Full text: For many years it has been agreed at the international level that the regulations for the control of discharges during normal operation from nuclear installation shall be based in the principles of individual dose limitation and optimization of the radiation protection focused on man. These regulations using a process of constrained optimization of protection, when properly applied to limit the discharges of radionuclides, were assumed to protect also other species than man and, within the available level of scientific knowledge, this assumption is still likely to be certain. After the International Conference on the Protection of the Environment from the Effects of Ionizing Radiation in Stockholm, 2003, many national, international, regional and non-governmental organizations have been working to develop a coherent international policy on the protection of the environment from effects attributable to exposures to ionizing radiation. One of the key issues to solve is how to include in the analysis and judgment process explicitly non-human species. Most of the organizations, particularly at the international level, have expressed their expectative in connection with the results of the work of the ICRP. In December 2007 the ICRP published its new recommendations and during 2008 key documents for the international community like the UNSCEAR document on effects of radiation on non-human biota and the ICRP publication on the approach to a framework for non-human protection using the concept of reference plants and animals could close, at least, the first chapter in this complex evolutionary process in the field of radiation protection. While some of the relevant topics for the protection of the environment from all the pollutants, like the global distribution patterns, the long term bioaccumulation effects, the relation of the individual effects regarding the communities and populations, Etc are still not fully discerned and noting that ICRP in its

The space environment and features on the moon surface are factors in strong electrostatic electrification. Static electricity will be produced in upon friction between lunar soil and detectors or astronauts on the lunar surface. Lunar electrostatic environment effects from lunar exploration equipment are very harmful. Lunar dust with electrostatic charge may enter the equipment or even cover the instruments. It can affect the normal performance of moon detectors. Owing to the huge environmental differences between the moon and the earth, the electrostatic protection technology on the earth can not be applied. In this paper, we review the electrostatic characteristics of lunar dust, its effects on aerospace equipment and moon static elimination technologies. It was concluded that the effect of charged lunar dust on detectors and astronauts should be completely researched as soon as possible.

The contribution of Landsat 8 TIRS sensor data to the identification of plastic covered vineyards

Science.gov (United States)

Novelli, Antonio; Tarantino, Eufemia

2015-06-01

Plastic covering is a common practice in agricultural fields. From an agronomic point of view, plastic coverings offer many advantages against unfavourable growing conditions. This explains their widespread utilization with consequent positive impact on local economy. On the other hand, plasticulture raises both environmental and landscape issues. In the Apulia Region (Italy) the wide implementation of such practice generally relates to vineyard cultivation. Continuous vineyard protection has resulted in negative effects on the hydrogeological balance of soils, causing a deep modification of the traditional rural landscape and therefore affecting its quality. To guarantee both the protection of local economy as well as the preservation of local environment and landscape features, a detailed site mapping of the areas involved is necessary. Indeed, the quantification of this phenomenon is essential in the periodic updating of the existing land use database and in the development of local policies. In this study we evaluate the potential of the novel Thermal Infrared Sensor bands (TIRS) provided by the LANDSAT 8 mission in plasticulture discrimination. Using the evident anomaly retrieved in the study area on the Quality Assessment (QA) band, a fast procedure involving TIRS data was developed, proposing a new index (Plastic Surface Index- PSI) able to emphasize plasticulture. For the aim of this study, two different acquisition dates on a test area in the Apulia region (Italy) were analyzed, one in the growing season with high plastic covering density and one in the post-harvest period with low plastic cover density.

Strand, P.; Brown, J. E.; Iospje, M.

2004-01-01

Sufficient information currently exists to introduce an overall framework for the protection of the environment from ionising radiation, drawing upon the large amount of radiobiological and radioecological information that has been gathered over the preceding decades. Nevertheless, there is a requirement to address numerous knowledge gaps and to improve upon existing databases. After the first presentation of a framework for the protection of the environment in 1999/2000 by the IUR, there has been activity to collate information and develop methodologies. This has allowed numerous recommendations to be made concerning future system development.. Although the transfer of radionuclides is quite well known within some food-chains, there are very few data on the behaviour of radionuclides in non-temperate zones and on uptake to species that do not form part of the human food chain. There is a need to develop both transfer models (flux, dynamic, ecosystem, etc.) and genotoxicological bio monitoring techniques that are capable of allowing impact assessments at a variety of species, population and ecosystem levels and that could also deal with other environmental stressors. Knowledge of the doses and effects of background radiation is lacking, as are dose-effect relationships, including information on RBE for a variety of species, doses and dose rates. The importance of various components of an environmental impact assessment can be explored, through the application of sensitivity and uncertainty analyses. An example of this type of analysis, for a marine system, demonstrated the importance of several radioecological parameters in the derivation of dose rates. However, although such examples provide insight, caution should be practiced in their interpretation. It is therefore suggested that further analyses are conducted in order to provide more robust priority lists for resource allocation. The recommendations made in this paper emphasize the need for further focussed

Full Text Available According to the overall requirements of ecological construction and environmental protection, rely on the national key ecological engineering, strengthen ecological environmental restoration and protection, improve forest cover, control soil erosion, construct important ecological security barrier in poor areas, inhibit poverty alleviation through ecological security in this area from environmental damage to the vicious cycle of poverty. Obviously, the dynamic monitoring of ecological security in contiguous destitute areas of Sichuan province has a policy sense of urgency and practical significance. This paper adopts RS technology and GIS technology to select the Luhe region of Jinchuan county and Ganzi prefecture as the research area, combined with the characteristics of ecological environment in poor areas, the impact factors of ecological environment are determined as land use type, terrain slope, vegetation cover, surface water, soil moisture and other factors. Using the ecological environmental safety assessment model, the ecological environment safety index is calculated. According to the index, the ecological environment safety of the research area is divided into four levels. The ecological environment safety classification map of 1990 in 2009 is obtained. It can be seen that with the human modern life and improve their economic level, the surrounding environment will be destroyed, because the research area ecological environment is now in good, the ecological environment generally tends to be stable. We should keep its ecological security good and improve local economic income. The relationship between ecological environmental security and economic coordinated development in poor areas has very important strategic significance.

Strategies for the protection of the environment from radiological hazards may benefit from a consideration of risk management strategies applied in other areas. This paper attempts to do that with respect to the way the OECD has addressed these issues. The paper briefly describes the approach developed within the OECD on harmonization and common approaches to chemicals risk management, related work by the Organisation on major industrial accidents and natural disasters, and places the relationship of chemical and radiological risk management in the context of the OECD Environmental Strategy for the First Decade of the Twenty-first Century.

Brownless, George; Lazo, Ted

2008-01-01

Full text: Development of radiological protection of non-human biota continues to be the focus of much interest and differing views amongst the radiological protection community. To nurture discussion of these developments, the Nuclear Energy Agency's Committee on Radiological Protection and Public Health is taking the lead in organising coverage of a spectrum of views on the topic at the International Conference on Radioecology and Radioactivity in the Environment (Bergen, 2008), with the aim of assisting the international community to construct a consensual, fit-for-purpose approach. To support discussion of these views, the session will also include scientific presentations and reports from implementers. This paper will report on these developments, based principally on the session at the Conference but also other activities in which NEA participates, to provide an up-to-date summary in this area including progress in developing understanding of how radiological protection of the environment will be implemented for the three exposure situations - planned, existing and emergency - set out in the new ICRP general recommendations. Furthermore, given the NEA's mandate across the civil nuclear energy field, the paper will give a commentary on how developments in radiological protection of the environment may interplay with new build of nuclear power plants.

Kleist, Nathan J; Guralnick, Robert P; Cruz, Alexander; Francis, Clinton D

Birds breeding in heterogeneous landscapes select nest sites by cueing in on a variety of factors from landscape features and social information to the presence of natural enemies. We focus on determining the relative impact of anthropogenic noise on nest site occupancy, compared to amount of forest cover, which is known to strongly influence the selection process. We examine chronic, industrial noise from natural gas wells directly measured at the nest box as well as site-averaged noise, using a well-established field experimental system in northwestern New Mexico. We hypothesized that high levels of noise, both at the nest site and in the environment, would decrease nest box occupancy. We set up nest boxes using a geospatially paired control and experimental site design and analyzed four years of occupancy data from four secondary cavity-nesting birds common to the Colorado Plateau. We found different effects of noise and landscape features depending on species, with strong effects of noise observed in breeding habitat selection of Myiarchus cinerascens, the Ash-throated Flycatcher, and Sialia currucoides, the Mountain Bluebird. In contrast, the amount of forest cover less frequently explained habitat selection for those species or had a smaller standardized effect than the acoustic environment. Although forest cover characterization and management is commonly employed by natural resource managers, our results show that characterizing and managing the acoustic environment should be an important tool in protected area management. © 2016 by the Ecological Society of America.

This article presents a workplace observations on manual work in cold environments and its impact on the selection of materials for protective gloves. The workplace observations was conducted on 107 workers in 7 companies and involved measurements of the temperature of air and objects in the workplaces; in addition the type of surface and shape of the objects was determined. Laboratory tests were also carried out on 11 materials for protective gloves to be used in cold environments. Protective characteristics, including mechanical properties (wear, cut, tear, and puncture resistance), insulation properties (thermal resistance), functional parameters, and hygienic properties (resistance to surface wetting, material stiffness) were evaluated. Appropriate levels of performance and quality, corresponding to the protective and functional properties of the materials, were determined. Based on the results of manual work and laboratory tests, directions for the selection of materials for the construction of protective gloves were formulated with a view to improving work ergonomics.

Climate Impacts of Cover Crops

Lombardozzi, D.; Wieder, W. R.; Bonan, G. B.; Morris, C. K.; Grandy, S.

2016-12-01

Cover crops are planted in agricultural rotation with the intention of protecting soil rather than harvest. Cover crops have numerous environmental benefits that include preventing soil erosion, increasing soil fertility, and providing weed and pest control- among others. In addition to localized environmental benefits, cover crops can have important regional or global biogeochemical impacts by increasing soil organic carbon, changing emissions of greenhouse trace gases like nitrous oxide and methane, and reducing hydrologic nitrogen losses. Cover crops may additionally affect climate by changing biogeophysical processes, like albedo and latent heat flux, though these potential changes have not yet been evaluated. Here we use the coupled Community Atmosphere Model (CAM5) - Community Land Model (CLM4.5) to test how planting cover crops in the United States may change biogeophysical fluxes and climate. We present seasonal changes in albedo, heat fluxes, evaporative partitioning, radiation, and the resulting changes in temperature. Preliminary analyses show that during seasons when cover crops are planted, latent heat flux increases and albedo decreases, changing the evaporative fraction and surface temperatures. Understanding both the biogeophysical changes caused by planting cover crops in this study and the biogeochemical changes found in other studies will give a clearer picture of the overall impacts of cover crops on climate and atmospheric chemistry, informing how this land use strategy will impact climate in the future.

The International union of radioecology has been created in 1970 as an international scientific organisation to develop, inform and advise on every aspect in relation with radioactivity in environment. It advises to fill the gaps of knowledge in order to develop strong scientific bases on which found the environmental protection. Seven points of knowledge are to improve: the understanding of transfer, bio accumulating and metabolism of radionuclides in ecosystems (specially the non human food chains), understanding of low dose radiation effects on fauna, flora in chronic exposure on several generations, identification of criteria and targets of effects to allow comparisons in term of impact, effects coming from several pollutions, radioactive or non radioactive ones, extrapolation between the biological organisation levels, analysis of simultaneous effects for man and other living organisms, harmonization of a radiation protection system and a protection system against chemical toxicity, development of quantities and units allowing to qualify the noxious effects of radiations and chemical pollutants on living beings.

Forty and a few years have passed away since the start of facilities agriculture using plastic covering materials. The facilities have been divided into heavily equipped type and simplified type. The former includes heating, ventilation, irrigation water, and nutritious solution culture facilities. The latter includes pipe house, tunnel, and rain shelter facilities. For the heavily equipped type, all season, long life-time and large-scale facilities have been diffused. Hard plates and hard films with durability equivalent to glass are used. Especially, utilization of hard films has been increased, recently. Soft films are also widely used for heavily equipped type facilities in spite of their disadvantage of taking large labor for renewal. However, enhancement of durability is also required for the soft films. Their life-time has become five years from the former one or two years. The significant problem of covering materials is the treatment of used plastics. Measures for enhancing the reproduction have been promoted. Furthermore, the development of naturally decomposed materials with biological and optical degradation properties has been also promoted. 11 refs., 2 figs., 2 tabs.

Land cover and its change analysis across the Hindu Kush Himalayan (HKH) region is realized as an urgent need to support diverse issues of environmental conservation. This study presents the first and most complete national land cover database of Nepal prepared using public domain Landsat TM data of 2010 and replicable methodology. The study estimated that 39.1% of Nepal is covered by forests and 29.83% by agriculture. Patch and edge forests constituting 23.4% of national forest cover revealed proximate biotic interferences over the forests. Core forests constituted 79.3% of forests of Protected areas where as 63% of area was under core forests in the outside protected area. Physiographic regions wise forest fragmentation analysis revealed specific conservation requirements for productive hill and mid mountain regions. Comparative analysis with Landsat TM based global land cover product showed difference of the order of 30-60% among different land cover classes stressing the need for significant improvements for national level adoption. The online web based land cover validation tool is developed for continual improvement of land cover product. The potential use of the data set for national and regional level sustainable land use planning strategies and meeting several global commitments also highlighted. Copyright © 2014 Elsevier Ltd.

Nevertheless, the effects of different urban land covers on energy and water fluxes has been rarely quantified across the large varieties of construction materials, landscaping and vegetation types, and industrial, commercial and residential areas in cities. In this study, we deployed a mobile eddy covariance tower at three different locations in the Phoenix, Arizona, metropolitan area to capture a variety of urban land covers. The three locations each represent a common urban class in Phoenix: 1) a dense, xeric landscape (gravel cover and native plants with drip-irrigation systems near tall buildings); 2) a high-density urban site (asphalt-paved parking lot near a high-traffic intersection); and 3) a suburban mesic landscape (sprinkler-irrigated turf grass in a suburban neighborhood). At each site, we measured meteorological variables, including air temperature and relative humidity at three heights, precipitation and pressure, surface temperature, and soil moisture and temperature (where applicable), to complement the eddy covariance measurements of radiation, energy, carbon dioxide and water vapor fluxes. We evaluated the tower footprint at each site to characterize the contributing surface area to the flux measurements, including engineered and landscaping elements, as a function of time for each deployment. The different sites allowed us to compare how turbulent fluxes of water vapor and carbon dioxide vary for these representative urban land covers, in particular with respect to the role of precipitation events and irrigation. While the deployments covered different seasons, from winter to summer in 2015, the variety of daily conditions allowed quantification of the differential response to precipitation events during the winter, pre

There were 384 (8877 square m) walls which covered with plant on 10 square km in the city of Tokyo, and the green wall rate in the city of Tokyo was 0.88%. Vines, for example Parthenocissus tricuspidata and Hedera helix, were widely used. The factor of thinking better of the landscape in urban area was one of the easily management of plants. The three wall greening systems, a wall covered with hanging climbers and two types of self-contained living wall, mitigated the thermal environment. However its degree can be depended on the greening method and the greenery occupancy rate of wall

This paper present the approach used at the VUJE institute for the evaluation of a ruptured blade impact on the current protection cover of a SKODA 220 MW turbine. Firstly, it briefly describes experiments (Hopkinson-Davies split bar facility, Taylor tests) and numerical simulations used to obtain realistic material parameters needed for the Cowper- Symonds material model that is implemented in the code LS-DYNA3D. Then, numerical simulations, by using the code, of the ruptured blade impact on various protection barriers are presented. These simulations make it possible to find an optimal solution for a new turbine protection cover. (author)

Natural radiation, protection against its effects and maintaining safe natural environment

2015-01-01

Exposure to naturally occurring radioactivity and its consequences is an issue that needs the global concern, as practices bringing such radioactive materials closer to human environment through mining, building, industrial applications and food production and preservation is continuously increasing, in addition to the daily consumption in foods such as banana, carrot, potato and drinking water. Although it has direct and indirect impacts affecting human health that in some cases lead to the loss of lives and polluting natural environment, it is an inevitable task that necessitates devising some means of its minimization and protection against its hazardous effects. This could be achieved by the use of expertise ideas and by the creation of awareness and sharing related information with the people concerned and the general public. This paper gives an overview on the radiation present in natural environment, its sources, mechanism of its effects. The paper compares the radiation dose limits with the average doses from these sources in order to raise the challenges facing researchers, governments and the general individuals with regard to this issue. The paper also proposed applicable solutions to reduce the risks due to the exposure to natural radiation to ground level. (author)

Research on smart environments saturated with ubiquitous computing devices is rapidly advancing while raising serious privacy issues. According to recent studies, privacy concerns significantly hinder widespread adoption of smart home technologies. Previous work has shown that it is possible to infer the activities of daily living within environments equipped with wireless sensors by monitoring radio fingerprints and traffic patterns. Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of  fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks.

Experiences Gained from Radiation Protection Activities in Egypt and Saudi Arabia

2004-01-01

My official duties and responsibilities in Egypt and Saudi Arabia as radiation safety officer, qualified expert and head of dosimetry section covered the specified branch of radiation protection. This branch may be called Applied Radiation Protection. This branch covers all aspects of personal and environmental dosimetry and monitoring, as well as, radiation measurements and shielding. This branch has been implemented at many universities, medical centers and nuclear organizations in both Egypt and Saudi Arabia. As a result, three subjects have been highlighted 1] Radiation Protection of workers, public and environment, 2) Safety of radioactive materials to ensure its control and 3) Security from unauthorized removal. A program has been proposed as (RPSS program). In this program, radiation workers are responsible for the security of all radioactive materials in their possession including radioactive waste in storage cabinets and sources left unattended on laboratory benches. Occupational radiation exposures have been kept below dose limits at all radiation areas by training increased experience and ability of radiation workers. All radioactive materials that are not in locked storage are under constant surveillance and immediate control at all times by Radiation Safety Officer (RSO) or medical physicist departments. Precautionary measures serve as a guide to safe operations in handling radioactive materials and radiation sources. Certain restricted areas, which contain large quantities of radioactive materials, required additional security measures. Implementation of this program led to secure of radioactive materials from unauthorized removal or access, public health, maintaining exposures as low as reasonably achievable and promoting a protective safe working environment with no contamination. It is recommended to include this program in Radiation Protection Manual and Emergency preparedness procedures at academic institutions, nuclear research facilities and

Australian and Canadian perspectives and regulations for protecting the polar marine environment

Energy Technology Data Exchange (ETDEWEB)

Rothwell, Donald R.

1997-12-31

The report compares Australian and Canadian responses for protecting polar marine environments. Vast areas of the polar seas fall within their potential combined EEZ/continental shelf jurisdiction. The Antarctic Treaty provisions, doubts on the status of the Northwest Passage waters and the capacity to enforce legislative initiatives against foreign vessels have been constraints. Australia`s enactment of legislation prohibiting mining within the AAT continental shelf and whaling within the AAT EEZ has tested the Antarctic Treaty. Canada`s reaction to the Manhattan and the enactment of the Arctic Waters Pollution Prevention Act is an example of unilateral action. While the countries have made noteworthy initiatives to enhance the protection of their polar marine environments, doubts remain in some instances on their capacity to give effect to the initiatives. However, sovereignty remains at the heart of their response. Failure to address Antarctic marine environmental issues will rebound on the environment and reflect poorly upon Australia`s sovereignty claim to the AAT. For Canada it is a sovereignty issue and has directly impact upon its citizens inhabiting the islands and coastal areas of the Canadian Arctic. The Madrid Protocol provides the strongest legal basis for the Antarctic Treaty parties to enact laws and regulations in Antarctica. Conservation measures adopted under the Convention for the Conservation of Antarctic Marine Living Resources focuses increasingly on environmental concerns. The most significant regional initiative adopted by Arctic states is the AEPS which does not have a legal foundation. It`s co-operative programs provide basis for co-operation in dealing with environmental problems. It clearly recognises that only co-operative responses will achieve significant outcomes. The 1990s have posed new challenges for marine environmental protection such as ship-based tourism in Antarctica and the growing pressure to use the Northwest Passage on a

The slow elimination of legal protection in connection with the law on the protection of the environment

International Nuclear Information System (INIS)

Geulen, R.

1980-01-01

The main cause of the reduction of legal protection against decisions under planning law and faits accomplis created during planning seems to stem from the practice adopted by those initiating and having an interest in projects, namely to prepare and somewhat anticipate the essential decisions long before government-controlle planning sets in. In fact, the licensing authorities which, according to their legal function, would have to check applications of operators with regard to licensing requirements, see themselves confined to follow a slow process of amalgamation with given, and, sometimes, factually executed planning decisions. In addition, the situation of the authorities regarding personnel and time does not allow them to carry out factual checking in its proper sense of, for example, licensing requirements for nuclear power plant construction. This process of amalgamation discussed by the author has an impact on the functions to be fulfilled by the courts, and on legal protection in general. The prognosis given by the author says that, due to this lack of efficient control by governmental authorities and courts especially in connection with the planning of large-scale projects likely to have an unfavourable effect on the environment, those persons or groups of persons feeling themselves insufficiently protected by the legal system, will more and more have recourse to political action rather than legal action.

Kainberger, F.; Kallinger, W.; Hofer, H.

1979-01-01

This is a report on the protective covering of the infant's pelvis. Comparative measurements of two customary lead covers, phantom measurements and comparative measurements on infants were carried out. Results show that a properly applied lead cover with a correct lead value (at least the equivalent of 1 mm of lead) may be considered a very effective protection against irradiation, a method that reduces irradiation to the gonads by a factor of 100. The initial dosis is at the surface and, as a rule, is below 1 mR. The dosis attaching the gonads is most likely within the micro-R-range. Thus we state for practical purposes that a lead protective cover is very effective in X-raying the infant pelvis - indeed it should be mandatory for every pelvic X-ray taken of infants. (author)

2000-01-01

The conflict among water drainage, water supply and eco-environment protection is getting more and more serious due to the irrational drainage and exploitation of ground water resources in coal-accumulated basins of North China. Efficient solutions to the conflict are to maintain long-term dynamic balance between input and output of the ground water basins, and to try to improve resourcification of the mine water. All solutions must guarantee the eco-environment quality. This paper presents a new idea of optimum combination of water drainage, water supply and eco-environment protection so as to solve the problem of unstable mine water supply, which is caused by the changeable water drainage for the whole combination system. Both the management of hydraulic techniques and constraints in economy, society, ecology, environment, industrial structural adjustments and sustainable developments have been taken into account. Since the traditional and separate management of different departments of water drainage,

2003-01-01

Protective coating materials used in the containment structures should be durable for the designed 30 to 40 year lifetime of a nuclear power plant. At the present, these materials have not yet been developed. Therefore it is very important to keep the durability of the protective coating materials through persistent maintenance, and in order to achieve this, understanding the adhesion characteristics of the coating materials is of utmost importance. Therefore, this study attempts to find any methods for durability maintenance of these protective coating materials. To accomplish these aims, this study applied an experimental deterioration environment condition relevant to Loss of Coolant Accident (LOCA) and Main Steam Line Break (MSLB), categorized as of Design Basis Accident (DBA), onto steel liner plate specimens covered with protective coating materials. Adhesion tests were performed on these deteriorated coating materials to characterize the physical properties and through these tests, the quantitative adhesion characteristics according to the history of deterioration environment were found

International guidelines on protective environment for HSCT recipients proposed a set of 10 global recommendations in 2009 on protective environment (GRPE) concerning hospital room design and ventilation. The EBMT Infectious Diseases Working Party undertook a survey on the status on protective environment for HSCT recipients with the aim of surveying current practices and their agreement with GRPE recommendations. The questionnaire consisted of 37 questions divided into 5 sections about filtration, air changes, maintenance, and the protective environment in rooms and the surrounding unit. Overall, 177 centres (response rate 33%) from 36 countries responded, indicating that 99.4% of patient rooms were equipped with HEPA filters, but only 48.6% of the centre's staff were aware of, and could confirm, regular replacement of filters based on manufacturers' recommendations. Well-sealed rooms were used in terms of windows (70.6%), ceilings (35%), and plumbing pipes (51.4%). The sensor monitors in the patient room used to determine when the HEPA filters require changing were installed only in 18.1% of centres. Only 1 centre fulfilled all 10 GRPE recommendations, while 62 centres fulfilled the 3 level "A" recommendations. In conclusion, HEPA-filtered rooms are available in almost all centres, while fewer centres fulfilled other requirements. Knowledge on the details and maintenance of protective environments in the HSCT setting was inadequate, reflecting a lack of communication between the health personnel involved, hospital infection control and the hospital maintenance services.

Optimising the use of plastic protective covers in field grown melon on a farm scale

Directory of Open Access Journals (Sweden)

Paolo Benincasa

2014-01-01

Full Text Available This in-farm research study was aimed at evaluating new strategies in the use of plastic protective covers in field grown melon in order to expand the production period and reduce costs. Four experiments were set up in 2010 and repeated in 2011 in Central Italy, in an inland region with a temperate climate. We evaluated: i the use of high tunnels for two growing cycles per year, i.e. for very early and very late production (target transplanting in late winter and mid-summer, respectively, for either one year or two consecutive years, and the use of grafted plants in the second year as an alternative to normal plants to prevent soil born diseases; ii the use of ethylene-vinyl-acetate film low tunnels alone or combined with non-woven floating row covers for transplanting in early spring; iii the use of non-woven low tunnels for transplanting in mid-spring; iv the use of biodegradable and conventional polyethylene ground mulch films, both in the presence of nonwoven low tunnels. As far as the non-woven cover is concerned, we adopted the strategy of removing later with respect to usual practices, i.e. ten days after the onset of first pistillate flowers. This was based on the evidence that covers hamper honeybee circulation, which may be exploited on a farm-scale to delay pollination until an adequate number of pistillate flowers set, in order to shorten scaled fruit ripening and harvest. Our results demonstrate that high tunnels may be used for at least four consecutive melon growing cycles (early and late productions for two years with good off-season yields and no appreciable drawbacks in terms of disease scale-up, irrespective of the use of normal or grafted plants. The non-woven low tunnel was effective in hampering honeybee circulation and its delayed removal allowed the harvest period to be halved, a more uniform fruit size to be obtained, and labour productivity of harvest to be increased. This had positive implications on the management of

Austrian Radiation Protection Association (OVS) share with others a long-standing tradition of common endeavours and close collaboration. We have been and are able to influence the European radiation protection environment and IRPA initiatives and policies. We are intrigued by the breadth and comprehensive nature of the symposium programme, covering the most important sub-fields in our profession, and spanning topics from radiation dosimetry to radiobiology, from instrumentation and measurement to radioecology, and from radiation protection for workers and in medicine to our professional responsibilities towards the general public. These topics are timeless and current, providing testimony to the fact that the science of radiation protection is not exhausted. Novel applications of ionizing and non-ionizing radiation, including new modalities in the fields of medical therapy and diagnosis, a resurgence of nuclear energy generation in some parts of the globe, combined with increased efforts for decontamination and decommissioning of existing sites and facilities, they are all attest to the continued need for further research and our professional input and discussion. The national radiation protection associations will have a role to play in both, the advocacy of increased efforts to educate and train our future professionals and the retention of those professionals in our field.

Ecological security pattern construction based on ecological protection redlines in China

Science.gov (United States)

Zou, Changxin

2017-04-01

China is facing huge environmental problems with its current rapid rate of urbanization and industrialization, thus causing biodiversity loss, ecosystem service degradation on a major scale. Against this background, three previous examples (the nature reserve policy, the afforestation policy, and the zoning policy) are implemented in China. These all play important roles in protecting natural ecosystems, although they can sometimes cause new problems and lack rigorous targets for environmental outcomes. To overcome current management conflicts, China has proposed a new "ecological protection redlines" policy (EPR). EPR can be defined as the ecological baseline area needed to provide ecosystem services to guarantee and maintain ecological safety. This study analyzed the scope, objectives and technical methods of delineating EPR in China, and put forward the proposed scheme for the ecological security pattern based on EPR. We constructed three kinds of redlines in China, including key ecological function area redlines, ecological sensitive or fragile areas redlines, and forbidden development areas redlines. For the key ecological function area redlines, a total of 38 water conservation functional zones have been designated, covering a total area of 3.23 million km2; 14 soil conservation zones have been designated, covering a total area of 881700 km2; wind-prevention and sand-fixation zones across the country cover a total area of about 1.73 million km2, accounting for 57.13% of the total land area of the whole country. With respect to the ecologically vulnerable redlines, 18 ecologically vulnerable zones has been designated across the country, covering 2.19 million km2, accounting for 22.86% of the total land area of the whole country. Forbidden development areas redlines covered a total area of 3.29 million km2, accounting for 34.3% of the total land area of the whole country. We also suggest to form a complete ecological security pattern including patterns of

The Science of Science Communication and Protecting the Science Communication Environment

Promoting public comprehension of science is only one aim of the science of science communication and is likely not the most important one for the well-being of a democratic society. Ordinary citizens form quadrillions of correct beliefs on matters that turn on complicated scientific principles they cannot even identify much less understand. The reason they fail to converge on beliefs consistent with scientific evidence on certain other consequential matters—from climate change to genetically modified foods to compusory adolescent HPV vaccination—is not the failure of scientists or science communicators to speak clearly or the inability of ordinary citizens to understand what they are saying. Rather, the source of such conflict is the proliferation of antagonistic cultural meanings. When they become attached to particular facts that admit of scientific investigation, these meanings are a kind of pollution of the science communication environment that disables the faculties ordinary citizens use to reliably absorb collective knowledge from their everyday interactions. The quality of the science communication environment is thus just as critical for enlightened self-government as the quality of the natural environment is for the physical health and well-being of a society's members. Understanding how this science communication environment works, fashioning procedures to prevent it from becoming contaminated with antagonistic meanings, and formulating effective interventions to detoxify it when protective strategies fail—those are the most critical functions science communication can perform in a democratic society.

This paper presents a way to use the ICRP approach for protection of the environment in generic assessments of the radiological impact of radioactive releases to the marine environment. Generic assessments of radiological impact to the environment are needed in certain circumstances, for example, when input data are limited or when the likely radiological consequences are expected to be not significant. Under these circumstances the effort in performing the assessment must be commensurate with the potential radiological consequences. The generic assessment described in this paper is a simple tool which provides reasonable and cautious results and is applicable to multiple exposure scenarios associated with the assessment of the radiological impact of releases to the marine the environment. This generic assessment can be also used to provide preliminary results which, when compared to radiological criteria, may determine the need of further specific assessments. The ICRP based its approach to protect the environment in the definition of a set of reference animals and plants and the use of related radiological criteria, in the form of derived consideration reference levels. The paper discusses selection and exposure conditions of the reference animals and plants, methods to estimate their doses and the use of the radiological criteria, for the purpose of a generic assessment. The IAEA is elaborating applications of these generic impact assessments presented in the paper to be included in international guidance under development. (authors)

The 1995 Symposium on Radiation Protection in Neighbouring Countries in Central Europe was a continuation of a series of conferences held by radiation protection societies and/or associations in Central Europe to promote the knowledge in radiation protection and to exchange scientific information and experience between countries in this region. Radiation hazards present a small part of all hazards to which the mankind is exposed these days. However, radiation protection do have a leading role in creating a strategy to minimize and regulate practices where various hazards are involved. This time the symposium was organized by Radiation Protection Association of Slovenia and J. Stefan Institute in cooperation with Austrian Association for Radiation Protection, Croatian Radiation Protection Association, Czech Society for Radiation Protection, Health Physics Section of Hungary, Italian Radiation Protection Association and Slovak Society of Nuclear Medicine and Radiation Hygiene. It was held in Portoroz, Slovenia. 112 papers were contributed as oral or poster presentations by 194 authors from 15 countries and two international organizations. Papers and posters covered a wide range of subjects, including: radiation protection at work place, natural radioactivity, nuclear instrumentation and dosimetry, emergency exposure situations, waste management, radiation protection principles and policies, radiation protection infrastructure, education, training and public relations and non-ionizing radiation. The well being of humans and other biota is tied in a very fundamental way to the environment, which make the environment a primary target for protection. That's why we believe that the activities of our Societies in future should be aimed at the protection of the environment in general, through a global and multi-disciplinary approach and the symposium demonstrated that there is a clear need for international communication and co-operation.

Energy-Efficient Privacy Protection for Smart Home Environments Using Behavioral Semantics

Homin Park

2014-09-01

Full Text Available Research on smart environments saturated with ubiquitous computing devices is rapidly advancing while raising serious privacy issues. According to recent studies, privacy concerns significantly hinder widespread adoption of smart home technologies. Previous work has shown that it is possible to infer the activities of daily living within environments equipped with wireless sensors by monitoring radio fingerprints and traffic patterns. Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of  fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks.

Full Text Available The objective of this work was to evaluate the floral biology and pollination requirements of seeded and seedless mini watermelon varieties, and to determine the best varieties to cultivate under protected environment. Three seedless (HA-5106, HA-5158, and HA-5161 and two seeded (Minipol and Polimore genotypes were tested. Flowers were monitored from the pre-anthesis stage to senescence, and fruit quality was also evaluated. The evaluated treatments were hand-geitonogamous pollination (MG, cross-pollination with pollen from the Polimore variety (MCP, cross-pollination with pollen from the Minipol variety (MCM, and restricted pollination. All varieties had monoecious plants with diclinous flowers, and the stigmas remained receptive throughout anthesis. Fruit set rates of 84.62% (MG, 61.54% (MCP, 48% (MCM, and 0% (restricted were obtained for seeded varieties, but of 0% (MG, 76.36% (MCP, 82.69% (MCM, and 0% (restricted for seedless varieties. Fruits did not differ in quality among treatments within each genotype. Therefore, all the studied varieties require a pollination agent and diploid pollen for fruit set to occur, regardless of the donor variety; and Minipol or Polimore with HA-5106 or HA-5158 are the varieties recommended for cultivation in protected environment.

Radiation Protection Act promulgated on May 19, 1988, SFS 1988: 220

International Nuclear Information System (INIS)

1988-01-01

This Act entered into force on 1 July 1988 and supersedes the previous Radiation Protection Act (SFS 1958: 110). The objective of the new Act is to protect humans, animals and the environment from the harmful effects of ionizing as well as non-ionizing radiation. As previously, the main responsibility for public radiation protection will rest with one central radiation protection authority. The general obligations with regard to radiation protection place a greater responsibility than in the past on persons carrying out activities involving radiation. The Act also contains rules governing decommissioning of technical equipment which could generate radiation. Basically, the same requirements still apply regarding licensing of activities involving ionizing radiation, with certain extensions covering, inter alia, also production and transportation of radioactive material. Under the Act, it is now possible to adjust the licensing and supervisory procedures to the level of danger of the radiation source and the need for adequate competence, etc., and finally, more effective supervision is provided for.

The development of international standards for the protection of the environment from the effects of ionizing radiation

International Nuclear Information System (INIS)

Robinson, Carol

2004-01-01

There has been an increasing awareness over recent years of the need to develop an approach that specifically addresses the protection of non-human species from the effects of ionizing radiation, largely in response to national and international environmental legal instruments. The IAEA has a long history of involvement in assessing the impact of ionizing radiation on non-human species and has, in recent years, established a programme of work to address the development of safety standards on this issue, in co-operation with other relevant international organizations. This paper provides an overview of the status of international work in this regard, paying particular attention to the work of the IAEA, and the relevant task groups of the International Commission on Radiological Protection (ICRP). It includes a discussion of the ethics and principles of environmental protection, and issues related to the development of a practical framework for environmental assessment and decision-making. The future development of international safety standards for the control of releases of radionuclides to the environment will depend upon the findings and recommendations of the International Conference on Protection of the Environment from the Effects of Ionizing Radiation, held in Stockholm, Sweden, 6-10 October 2003. The main issues arising at that conference are summarised. (author)

In order to make clear the difference of the response time between the oxygen sensors with different protection covers, we visualized gas flow inside of sensor covers by means of two experimental methods: One is `Smoke Suspension Method` using liquid paraffin vapor as the smoke. With smoke suspension method, we detected the streamlines inside of the covers. The other is `Color Reaction Method` using the reaction of phenolphthalein and NH3 gas. With color reaction method, we confirmed the streamline inside of the cover and furthermore detected the difference of the response time of each sensor. 3 refs., 7 figs., 1 tab.

LeProvost, M.I.; Gordon, D.M.

1991-01-01

In recent years a number of oilfields have been developed in tropical waters of the Rowley Shelf, north-west Australia. Along with Bass Strait and the Timor Sea, this region is the focus for Australia's current oil exploration and production. It supports major coral and mangrove habitats and fishing grounds sensitive to the effects of oil pollution. This paper provides a synthesis of the Rowley Shelf marine environment and reviews procedures protecting the marine resources of the region from the effects of oil spills. Recent government and industry initiatives for improving the protection of the environment are outlined and discussed on the basis of the improved understanding of the marine resources and experience being gained in oil spill contingency planning. The tropical habitats of the Rowley Shelf occur within the Indo-Pacific Zoogeographic Region, therefore experience gained in Western Australia is applicable to similar environments in the South East Asian region

Communication in hazardous environments

International Nuclear Information System (INIS)

Rankin, W.N.; Herold, T.R.

1986-01-01

Radios were investigated for use in hazardous environments where protective breathing equipment such as plastic suits and respirators interfere with communication. A radio system, manufactured by Communications-Applied technology (C-AT), was identified that was designed specifically for hazardous environment communications. This equipment had been used successfully by the US Army and NASA for several years. C-AT equipment was evaluated in plantwide applications at the Savannah River Plant (SRP) using temporary frequencies obtained by the Department of Energy-Savannah River (DOE-SR). Radios performed well in all applications, which included a tritium facility, high-level caves, a nuclear reactor building, tank farm, and a canyon building interior. Permanent frequencies were obtained by DOE-SR for two complete six-man C-AT systems at SRP. Because of the relatively short range of these systems, replicates will cover all applications of this type of equipment plantwide. Twelve radio systems are currently being used successfully in plantwide applications

Prevalence of Pure Versus Mixed Snow Cover Pixels across Spatial Resolutions in Alpine Environments

David J. Selkowitz

2014-12-01

Full Text Available Remote sensing of snow-covered area (SCA can be binary (indicating the presence/absence of snow cover at each pixel or fractional (indicating the fraction of each pixel covered by snow. Fractional SCA mapping provides more information than binary SCA, but is more difficult to implement and may not be feasible with all types of remote sensing data. The utility of fractional SCA mapping relative to binary SCA mapping varies with the intended application as well as by spatial resolution, temporal resolution and period of interest, and climate. We quantified the frequency of occurrence of partially snow-covered (mixed pixels at spatial resolutions between 1 m and 500 m over five dates at two study areas in the western U.S., using 0.5 m binary SCA maps derived from high spatial resolution imagery aggregated to fractional SCA at coarser spatial resolutions. In addition, we used in situ monitoring to estimate the frequency of partially snow-covered conditions for the period September 2013–August 2014 at 10 60-m grid cell footprints at two study areas with continental snow climates. Results from the image analysis indicate that at 40 m, slightly above the nominal spatial resolution of Landsat, mixed pixels accounted for 25%–93% of total pixels, while at 500 m, the nominal spatial resolution of MODIS bands used for snow cover mapping, mixed pixels accounted for 67%–100% of total pixels. Mixed pixels occurred more commonly at the continental snow climate site than at the maritime snow climate site. The in situ data indicate that some snow cover was present between 186 and 303 days, and partial snow cover conditions occurred on 10%–98% of days with snow cover. Four sites remained partially snow-free throughout most of the winter and spring, while six sites were entirely snow covered throughout most or all of the winter and spring. Within 60 m grid cells, the late spring/summer transition from snow-covered to snow-free conditions lasted 17–56 days

Variability, plot size and border effect in lettuce trials in protected environment

Directory of Open Access Journals (Sweden)

Daniel Santos

2018-03-01

Full Text Available ABSTRACT The variability within rows of cultivation may reduce the accuracy of experiments conducted in a complete randomized block design if the rows are considered as blocks, however, little is known about this variability in protected environments. Thus, our aim was to study the variability of the fresh mass in lettuce shoot, growing in protected environment, and to verify the border effect and size of the experimental unit in minimizing the productive variability. Data from two uniformity trials carried out in a greenhouse in autumn and spring growing seasons were used. In the statistical analyses, it was considered the existence of parallel cultivation rows the lateral openings of the greenhouse and of columns perpendicular to these openings. Different scenarios were simulated by excluding rows and columns to generate several borders arrangements and also to use different sizes of the experimental unit. For each scenario, homogeneity test of variances between remaining rows and columns was performed, and it was calculated the variance and coefficient of variation. There is variability among rows in trials with lettuce in plastic greenhouses and the border use does not bring benefits in terms of reduction of the coefficient of variation or minimizing the cases of heterogeneous variances among rows. In experiments with lettuce in a plastic greenhouse, the use of an experimental unit size greater than or equal to two plants provides homogeneity of variances among rows and columns and, therefore, allows the use of a completely randomized design.

1975-10-01

A structural evaluation of the bellows and bellows cover sections was undertaken in order to confirm the structural integrity of these TFTR vacuum vessel components in the prescribed operating environment. The evaluations investigate component stability, stress, and deflection behavior. The products of this investigation appearing in this report include; (1) Structural verification of the vacuum bellows as currently defined in an operating environment of one atmosphere external pressure and 93 0 C (200 0 F) uniform temperature. (2) The establishment of a structurally adequate design configuration for the bellows cover section. (3) The presentation of a parametric study which indicates the effects of varying some bellows cover section parameters in order to obtain acceptable variations of this design configuration. (4) A verification of bellows and bellows cover section integrity to preclude a fatigue type failure for reactor startup and shutdown cyclic life in the design environment

An atmospheric vulnerability assessment framework for environment management and protection based on CAMx.

Science.gov (United States)

Zhang, Yang; Shen, Jing; Li, Yu

2018-02-01

This paper presents an atmospheric vulnerability assessment framework based on CAMx that should be helpful to assess potential impacts of changes in human, atmospheric environment, and social economic elements of atmospheric vulnerability. It is also a useful and effective tool that can provide policy-guidance for environmental protection and management to reduce the atmospheric vulnerability. The developed framework was applied to evaluate the atmospheric environment vulnerability of 13 cities in the Beijing-Tianjin-Hebei (BTH) region for verification. The results indicated that regional disparity of the atmospheric vulnerability existed in the study site. More specifically, the central and southern regions show more atmospheric environment vulnerability than the northern regions. The impact factors of atmospheric environment vulnerability in the BTH region mainly derived from increasing population press, frequently unfavorable meteorological conditions, extensive economic growth of secondary industry, increased environmental pollution, and accelerating population aging. The framework shown in this paper is an interpretative and heuristic tool for a better understanding of atmospheric vulnerability. This framework can also be replicated at different spatial and temporal scales using context-specific datasets to straightly support environmental managers with decision-making.

Temporary and permanent cover crops were used in three rain fed vineyards in the Center of Spain. They were sown in the middle of the strips to assess their ability to control erosion as well as their influence on grape production. Data from the year 2008 are compared with those obtained with traditional tillage treatment. The permanent cover formed by Brachypodium distachyon showed better ability to control erosion but it produced a decrease in production in young vines. barley and rye treatments were temporary covers, mowed in spring. They also reduced the erosion compared with the tillage however they did not appear to affect the vineyard production. (Author)

Carbon steel protection in G.S. (Girlder sulfide) plants. Iron sulfide scales formation on surfaces covered by fabrication produced films. Pt. 4

International Nuclear Information System (INIS)

Burkart, A.L.

1986-04-01

This work describes the assays aimed to passivate the steel carbon of the process pipings. This steel is marked by the ASTM A 333 G6 and is chemically similar to those of isotopic exchange towers which corrode in contact with in-water hydrogen sulfide solutions forming iron sulfide protective layers. The differences between both materials lie in the surface characteristics to be passivated. The steel of towers has an internal side covered by paint which shall be removed prior to passivation. The steel's internal side shall be covered by a film formed during the fabrication process and constituted by calcinated wastes and iron oxides (magnetite, hematite and wustite). This film interferes in the formation process of passivating layers of pyrrhotite and pyrite. The possibility to passivate the pipes in their actual state was evaluated since it would result highly laborious and expensive to eliminate the film. (Author) [es

Special study on vegetative covers

International Nuclear Information System (INIS)

1988-11-01

This report describes the findings of a special study on the use of vegetative covers to stabilize tailings piles for the Uranium Mill Tailings Remedial Action (UMTRA) Project. The principal rationale for using plants would be to establish a dynamic system for controlling water balance. Specifically, vegetation would be used to intercept and transpire precipitation to the atmosphere, rather than allowing water to drain into the tailings and mobilize contaminants. This would facilitate compliance with groundwater standards proposed for the UMTRA Project by the Environmental Protection Agency. The goals of the study were to evaluate the feasibility of using vegetative covers on UMTRA Project piles, define the advantages and disadvantages of vegetative covers, and develop general guidelines for their use when such use seems reasonable. The principal method for the study was to analyze and apply to the UMTRA Project the results of research programs on vegetative covers at other US Department of Energy (DOE) waste management facilities. The study also relied upon observations made of existing stabilized piles at UMTRA Project sites where natural vegetation is growing on the rock-covered surfaces. Water balance and erosion models were also used to quantify the long-term performance of vegetative covers planned for the topslopes of stabilized piles at Grand Junction and Durango, Colorado, two UMTRA Project sites where the decision was made during the course of this special study to use vegetative covers. Elements in the design and construction of the vegetative covers at these two sites are discussed in the report, with explanations of the differing features that reflect differing environmental conditions. 28 refs., 18 figs., 9 tabs

Although rates of late-stage melanoma are rising in Hispanics, particularly those living in high ultraviolet light environments, little is known about the prevalence of sun protective behaviors in Hispanic children. We analyzed baseline data including frequency of sunburn, sun protective behaviors, level of U.S. acculturation, and skin phototype from a cross-sectional survey of 2003 Hispanic elementary school children in Los Angeles, California, who participated in a skin cancer prevention intervention. Although the Hispanic children reported frequently engaging in some sun protective behaviors, they also had a high rate of sunburn (59%) that exceeded previous national estimates for non-Hispanic white children (43%). Fewer U.S.-acculturated children reported more frequent shade-seeking at home (P = .02), along with less shade-seeking at school (P = .001) and more sunscreen use at school (P = .02). The surprisingly high rate of sunburn in Hispanic children suggests that the way in which they are practicing sun protection is not preventing sunburns. Sun safety interventions should be targeted toward Hispanic youth to provide them with practical methods of effective sun protection, in addition to education on the risks of high sun exposure. © 2017 Wiley Periodicals, Inc.

Full Text Available The satellite imagery has been effectively utilized for classifying land covertypes and detecting land cover conditions. The Advanced Spaceborne Thermal Emissionand Reflection Radiometer (ASTER sensor imagery has been widely used in classificationprocess of land cover. However, atmospheric corrections have to be made by preprocessingsatellite sensor imagery since the electromagnetic radiation signals received by the satellitesensors can be scattered and absorbed by the atmospheric gases and aerosols. In this study,an ASTER sensor imagery, which was converted into top-of-atmosphere reflectance(TOA, was used to classify the land use/cover types, according to COoRdination ofINformation on the Environment (CORINE land cover nomenclature, for an arearepresenting the heterogonous characteristics of eastern Mediterranean regions inKahramanmaras, Turkey.

The U.S. Department of Energy Office of Legacy Management is evaluating methods to enhance natural changes that are essentially converting conventional disposal cell covers for uranium mill tailings into water balance covers. Conventional covers rely on a layer of compacted clayey soil to limit exhalation of radon gas and percolation of rainwater. Water balance covers rely on a less compacted soil “sponge” to store rainwater, and on soil evaporation and plant transpiration (evapotranspiration) to remove stored water and thereby limit percolation. Over time, natural soil-forming and ecological processes are changing conventional covers by increasing hydraulic conductivity, loosening compaction, and increasing evapotranspiration. The rock armor on conventional covers creates a favorable habitat for vegetation by slowing soil evaporation, increasing soil water storage, and trapping dust and organic matter, thereby providing the water and nutrients needed for plant germination, survival, and sustainable transpiration. Goals and Objectives Our overall goal is to determine if allowing or enhancing these natural changes could improve cover performance and reduce maintenance costs over the long term. This test pad study focuses on cover soil hydrology and ecology. Companion studies are evaluating effects of natural and enhanced changes in covers on radon attenuation, erosion, and biointrusion. We constructed a test cover at the Grand Junction disposal site to evaluate soil manipulation and revegetation methods. The engineering design, construction, and properties of the test cover match the upper three layers of the nearby disposal cell cover: a 1-foot armoring of rock riprap, a 6-inch bedding layer of coarse sand and gravel, and a 2-foot protection layer of compacted fine soil. The test cover does not have a radon barrier—cover enhancement tests leave the radon barrier intact. We tested furrowing and ripping as means for creating depressions parallel to the slope

Over the last decade, deforestation in Indonesia has reduced the forest area down to more than 6 million hectares. There is conflict that the protected forest ecosystem service is still often perceived as public goods. Many of them went unrecognized in planning process and continue to be undervalued. The challenge lies in maintaining socioeconomic development and ecosystem services sustainability without overlooking the people’s opportunities and improving their livelihoods over the long term. An integrated approach is required to understand the comprehensive concept of protected forest ecosystem service. This research aims to formulate a scheme of payment for ecosystem service (PES) in a protected forest. It is a first step towards the attempt for the value of ecosystem services to be reflected in decision-making. Literatures, previous researches and secondary data are reviewed thoroughly to analyze the interrelated components by looking at the environment as a whole and recognize their linkages that have consequences to one another both positive and negative. The framework of implementation of PES schemes outlines the complexity of human-environment interconnecting relationships. It evaluates the contributing actors of different interest i.e. long term use and short term use. The concept of PES accommodates the fulfillment of both conservation and exploitation with an incentive scheme to the contributing parties who are willing to implement conservation and issuance of compensation expense for any exploitation means. The most crucial part in this concept is to have a good and effective communication between every policy makers concerning the forest ecosystem and local communities.

An alternative cover design consisting of a monolithic layer of native soil is proposed as the closure path for the Mixed Waste Landfill at Sandia National Laboratories, New Mexico. The proposed design would rely upon soil thickness and evapotranspiration to provide long-term performance and stability, and would be inexpensive to build and maintain. The proposed design is a 3-ft-thick, vegetated soil cover. The alternative cover meets the intent of RCRA Subtitle C regulations in that: (a) water migration through the cover is minimized; (b) maintenance is minimized by using a monolithic soil layer; (c) cover erosion is minimized by using erosion control measures; (d) subsidence is accommodated by using a ''soft'' design; and (e) the permeability of the cover is less than or equal to that of natural subsurface soil present. Performance of the proposed cover is integrated with natural site conditions, producing a ''system performance'' that will ensure that the cover is protective of human health and the environment. Natural site conditions that will produce a system performance include: (a) extremely low precipitation and high potential evapotranspiration; (b) negligible recharge to groundwater; (c) an extensive vadose zone; (d) groundwater approximately 500 ft below the surface; and (e) a versatile, native flora that will persist indefinitely as a climax ecological community with little or no maintenance.

Best Dressed Test: A Study of the Covering Behavior of the Collector Urchin Tripneustes gratilla.

Directory of Open Access Journals (Sweden)

Morgan A Ziegenhorn

Full Text Available Many sea urchin genera exhibit cryptic covering behaviors. One such behavior has been documented in the sea urchin Tripneustes gratilla, and previous studies have theorized that this behavior serves as protection from UV radiation. However, other hypotheses have been presented such as protection from predators or added weight to help T. gratilla resist strong currents. A field study was conducted in October-November 2015 in Moorea, French Polynesia to assess urchin covering behavior in natural habitats. The study found that urchins partially underneath rocks covered more, and with more algae, than urchins totally underneath rocks. To test if this behavior was driven by light intensity, a series of 30-minute experimental trials were run on 10 individuals in bright and dim conditions. Individuals were given red and clear plastic, and percent cover of each was recorded. These tests were repeated once fifty percent of spines had been removed from the urchin, in order to determine whether spine loss affects T. gratilla covering behavior. The study found that urchins had a distinct preference for cover that best protects them from UV radiation. Spine loss did not significantly affect urchin ability to cover, and urchins with removed spines still preferred opaque cover. Additionally, covering behavior was mapped onto a phylogeny of echinoderms to determine how it might have evolved. Understanding urchin covering behavior more fully is a step towards an understanding of the evolution of cryptic behavior across species.

Forest is the lung of the earth, and it has important effect on maintaining the ecological balance of the whole earth. This study was conducted in Inner Mongolia during the year 1990-2015. Land use and land cover data were used to obtain forest cover change of Inner Mongolia. In addition, protected area data, road data, ASTER GDEM data were combined with forest cover change data to analyze the relationship between them. Moreover, patch density and landscape shape index were calculated to analyze forest change in perspective of landscape aspect. The results indicated that forest area increased overall during the study period. However, a few cities still had a phenomenon of reduced forest area. Results also demonstrated that the construction of protected area had positive effect on protecting forest while roads may disturbed forest due to human activities. In addition, forest patches in most of cities of Inner Mongolia tended to be larger and less fragmented. This paper reflected forest change in Inner Mongolia objectively, which is helpful for policy making by government.

Capability and limits of EC policy and instruments for protection of the environment

The authors who contributed to this compilation of studies start from different points of view in their approaches towards describing the existing (or desirable) balance between centralised and decentralised frameworks and instruments of the EC policy for protection of the environment: A total harmonisation of environmental protection standards would be inconsistent with the principles of competition and, in terms of environmental protection, would rather foster a climate tending to be hostile to innovation. The impetus given by the EC in support of free mobility in the transport sector of the internal market on the other hand ought to be flanked by mandatory ecological standards. Adhering to the economic theory of federalism would mean to decide for a high degree of decentralisation, which in turn does not seem to be altogether appropriate in view of the large scope of impact of environmental damage and the mutual ecological dependence of EC member states. A more centralised regulatory competence has to be accompanied by correspondingly strong, democratic institutions in order to fulfill the principles of constitutional law. The priority given to the principle of subsidiarity in the compromise laid down in the Treaty of Maastricht needs to be given concrete shape [de

Inuit have travelled to and settled in the coastal landscapes of Northeast Greenland for several longer periods during the latest ca. 4500 years. Most recently the Thule culture Inuit lived in the region from around 1400 until 1850 AD. The access to partly and periodically ice covered near coastal...... waters has been crucial to the primarily marine based subsistence strategy of the Thule Inuit culture, and their settlements are therefore found immediately at the coast. Changing geological and geomorphologic settings strongly influence the coastal morphodynamics, and only specific locations offer...... stable and protected conditions needed for proper winter settlements. The comprehensive study of coastal environments and Thule culture winter settlements in the Young Sound region show an accumulation of winter settlements, nearly all located either in protected pocket beaches or on stable basalt capes...

Uriel Jeshua Sánchez-Reyes

2017-07-01

Full Text Available Loss of vegetation cover is a major factor that endangers biodiversity. Therefore, the use of geographic information systems and the analysis of satellite images are important for monitoring these changes in Natural Protected Areas (NPAs. In northeastern Mexico, the Natural Protected Area Altas Cumbres (NPAAC represents a relevant floristic and faunistic patch on which the impact of loss of vegetation cover has not been assessed. This work aimed to analyze changes of land use and coverage (LULCC over the last 42 years on the interior and around the exterior of the area, and also to propose the time of succession for the most important types of vegetation. For the analysis, LANDSAT satellite images from 1973, 1986, 2000, 2005 and 2015 were used, they were classified in seven categories through a segmentation and maximum likelihood analysis. A cross-tabulation analysis was performed to determine the succession gradient. Towards the interior of the area, a significant reduction of tropical vegetation and, to a lesser extent, temperate forests was found, as well as an increase in scrub cover from 1973 to 2015. In addition, urban and vegetation-free areas, as well as modified vegetation, increased to the exterior. Towards the interior of the NPA, the processes of perturbation and recovery were mostly not linear, while in the exterior adjacent area, the presence of secondary vegetation with distinct definite time of succession was evident. The analysis carried out is the first contribution that evaluates LULCC in this important NPA of northeastern Mexico. Results suggest the need to evaluate the effects of these modifications on species.

2015-06-01

Full Text Available In regions with intense solar radiation it is common the use of aluminated covers in greenhouses, with the aim of reducing the inside temperature. However, the use of these covers reduces photosynthetic active radiation (PAR transmitted into the greenhouse. The objective of the present study was to evaluate the influence of different covers on microclimate in greenhouses cultivated with cherry tomato during three growing seasons. The environment I was covered with plastic film anti-UV and with thermo-reflective screen (40% disposed internally. The environment II was covered with diffusive plastic film (55%. The transmitted solar radiation to the interior of covered environments was, on average, 5.5 MJ m-2 day-1 in the environment I and 8.2 MJ m-2 day-1 in environment II. The air temperature in environment II was, on average, 1°C higher than external conditions. The highest difference for the relative humidity (RH was also observed between environment II and the outside conditions, with 10.7% for the minimum RH during the first growing period. Considering all growing periods, the diffusive plastic film provided higher solar energy availability inside the greenhouse than the plastic film with thermo-reflective screen, without causing major changes in air temperature and relative humidity, and promoting greater productivity of tomato grown under this environment for the three periods evaluated.

Full Text Available The article investigates the processes of health protection at modern industrial enterprises. Occupational health of workers is considered in the article as an important component of the sustainable development of the enterprise. The process of health protection is described in the study not only as a social component, but also as a process relating to all areas of sustainable development. The article attempts to show the place of ‘health-protection subsystem’ as part of an integrated system of industrial enterprises’ sustainable development. Four independent spheres of health protection programs implementation were pointed out at the level of enterprise – professional environment, the quality of workplace, involvement of employees in the process of health protection, involvement of the enterprise in the processes of health protection. The article emphasizes the interrelationship of biological and economic characteristics of human life and society in the formation of health protection processes. Programs for sustainable development taking into account the management of health protection should include two sets of activities: corrective and special ones. Tools used in health management programs aimed at expanding the choices of healthier behavior and altering the character of individual preferences in behavior within the framework of the formation of health tastes and preferences are defined. The authors present the results of the analysis of occupational diseases on the example of the three companies of the Perm region (Saranovskaya shakhta ‘Rudnaya’ OJSC, Motovilikhinskie zavody PJSC and Proton-PM PJSC. The results allowed to offer a list of universal and special arrangements for the implementation of health protection control programs within the mentioned industrial enterprises.

Full Text Available Genipap (Genipa americana L., Rubiaceae is a native Brazilian species and can be used in the recovery of degraded forest areas or for food supply. In order for the species to reach its potential, production of high quality seedlings is essential. The objective of this study was to evaluate genipap seedlings in protected environments and different substrates. The environments tested were: (1 a greenhouse with polyethylene film in the top, with aluminized screen (Aliminet® of 50%-shading under this film, and lateral sides covered with 50%-shading nylon net (Sombrite®, (2 a shaded hut, all sides covered with 50%-shading nylon net (Sombrite®, and (3 a nursery shelter, with all lateral sides uncovered and the roof covered with leaves of buriti (Mauritia flexuosa. In these environments the following substrates were tested: 50% cattle manure + 50% cassava foliage, 50% cattle manure + 50% Vida Verde®, 50% cattle manure + 50% vermiculite, and 25% cattle manure + 25% vermiculite + 25% of cassava foliage + 25% Vida Verde®. Because there was no repetition of the growth environment, the effect of environment was examined using statistical procedures for analysis of combined experiments. Within environments a completely randomized design was used with five replications. All substrates are suitable for the formation of genipap seedlings, where the recommended substrates are: 50% cattle manure + 50% cassava foliage and 50% cattle manure + 50% Vida Verde® for the greenhouse and the substrates composed of 50% cattle manure + 50% vermiculite and 25% cattle manure + 25% cassava foliage + 25% Vida Verde®+ 25% vermiculite for the shaded hut. The buriti shelter is not recommended for production of genipap seedlings.O jenipapo (Genipa americana L., Rubiaceae é uma espécie brasileira nativa e pode ser utilizada na recomposição de áreas de florestas degradadas ou fornecimento de alimentos.

The majority of the countries of the world, especially developing countries, face environmental problems. Limitations of basic resources (water and soil) and population growth have been the cause of these environmental problems that countries are confronted with. Developing countries have numerous problems, including destruction of forests, vegetable and animal species, and pollution of the environment. Damage to natural resources and the environment can influence the food-security situation. One of the main millennium development goals (MDGs) is protection of the environment and people's health. This cannot obtained unless there is ensured food security. Food security has been defined as a situation when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food needed to maintain a healthy and active life. At the same time, with ensured food security, we can hope to protect the natural resources and environment. The methodology used is descriptive-analytical, and its main purpose is determining the importance and role of food-security solutions in the reduction of environmental hazards and improvement of natural resources and the environmental situation in developing countries. Therefore, some of the most important food-security solutions that can play an important role in this relation were discussed, including conventional research-based technology, biotechnology, information and communication technologies (ICTs), alternative energy sources, and food irradiation.

Perspectives for environmental radiation protection in EU radiation protection legislation

International Nuclear Information System (INIS)

Janssens, A.

2000-01-01

The basis of EU radiation protection legislation is the EURATOM Trealy. It is discussed whether the Treaty offers a legal basis for the protection of the natural environment. The incorporation of provisions pertaining to the nuclear fuel cycle or to radioactive substances in general environmental legislation is explained, as well as the possible implications of international conventions subscribed by the European Union. The European Commission is in the process of developing an overall approach to risk analysis for the protection of health, consumer interests, and the environment. It is examined to what extent the consideration of the impact of radiation on the natural environment fits in the overall framework and whether the principles underlying classical radiation protection are applicable to biota. Specific attention is given to situations where high levels of environmental radioactivity would require intervention. (Author)

Full Text Available Tourist activities motivate tourists to visit a destination. Tourism evaluates motives and protects them largely from harmful influences. Tourism evaluation aims to establish the value of natural tourist attractions and of those created by humans. Along with tourist attractions, destinations are also evaluated in order to find out about their utility. The evaluation of a destination and its particular attractions is expressed by the realized tourist traffic for the observed period. Protection of tourist attractions is a systematic activity against all kinds of pollution. It also includes the sustainability of traffic flows in tourism destination. Management in tourism industry has an irreplaceable role in that.

Design surface covers: an approach to long-term waste site stabilization

International Nuclear Information System (INIS)

Beedlow, P.A.; Cadwell, L.L.; McShane, M.C.

1983-02-01

The wide range of existing environmental conditions, potential contaminants and available cover materials at waste disposal sites necessitates site-specific designing of surface covers for effective long-term erosion resistance. This paper presents a systematic approach to designing surface covers for hazardous waste repositories that can be tailored to conditions at any site. The approach consists of three phases: (1) an assessment, during which the degree of required surface protection (erosion potential) is determined; (2) a preliminary design that integrates surface cover design with the need to minimize transport of contaminants; and (3) a final design, where the cost and effectiveness of the surface cover are determined. 1 figure

DIII-D in-vessel port cover and shutter assembly for the phase contrast interferometer

International Nuclear Information System (INIS)

Phelps, R.D.

1994-01-01

The entire outer wall of the DIII-D vacuum vessel interion is covered with a regular array of graphite tiles. Certain of the diagnostic ports through the outer vessel wall contain equipment which is shielded from the plasma by installing port covers designed to withstand energy deposition. If the diagnostic contained in the port must communicate with the vessel volume, a shutter assembly is usually provided. In the ports at 285 degrees, R+1 and R-1, interferometer mirrors have been installed to provide a means for transmitting a large diameter CO-2 laser beam through the edge of the plasma. To protect the mirrors and other hardware contained in these ports, a special protective plate and shutter arrangement has been designed. This report describes the details of design, fabrication, and installation of these protective covers and shutters

Optimization of the Area 5 Radioactive Waste Management Site Closure Cover

Energy Technology Data Exchange (ETDEWEB)

Shott, Greg; Yucel, Vefa

2009-04-01

The U.S. Department of Energy Manual DOE M 435.1-1, “Radioactive Waste Management Manual,” requires that performance assessments demonstrate that releases of radionuclides to the environment are as low as reasonably achievable (ALARA). Quantitative cost benefit analysis of radiation protection options is one component of the ALARA process. This report summarizes a quantitative cost benefit analysis of closure cover thickness for the Area 5 Radioactive Waste Management Site (RWMS) on the Nevada Test Site. The optimum cover thickness that maintains doses ALARA is shown to be the thickness with the minimum total closure cost. Total closure cost is the sum of cover construction cost and the health detriment cost. Cover construction cost is estimated based on detailed cost estimates for closure of the 92-acre Low-Level Waste Management Unit (LLWMU). The health detriment cost is calculated as the product of collective dose and a constant monetary value of health detriment in units of dollars per unit collective dose. Collective dose is the sum of all individual doses in an exposed population and has units of person-sievert (Sv). Five discrete cover thickness options ranging from 2.5 to 4.5 meters (m) (8.2 to 15 feet [ft]) are evaluated. The optimization was subject to the constraints that (1) options must meet all applicable regulatory requirements and that (2) individual doses be a small fraction of background radiation dose. Total closure cost is found to be a monotonically increasing function of cover thickness for the 92-ac LLWMU, the Northern Expansion Area, and the entire Area 5 RWMS. The cover construction cost is orders of magnitude greater than the health detriment cost. Two-thousand Latin hypercube sampling realizations of the relationship between total closure cost and cover thickness are generated. In every realization, the optimum cover thickness is 2.5 m (8.2 ft) for the 92-ac Low-Level Waste Management Unit, the Northern Expansion Area, and the entire

Systematic approach to designing surface covers for uranium-mill tailings

International Nuclear Information System (INIS)

Beedlow, P.A.; Cadwell, L.L.; McShane, M.C.

1982-01-01

The wide range of environmental conditions present at uranium mill tailings sites precludes the use of a single type of surface cover. Surface covers must be designed on a site-specific basis. To facilitate site specific designs the UMTRA program is developing guidelines for designing surface covers. This paper presents a systematic approach to designing surface covers for tailings that can be applied under any site condition. The approach consists of three phases: (1) An assessment during which the degree of surface protection is determined. (2) A preliminary design that facilitates interaction with those designing other containment system elements. (3) A final design where the cost and effectiveness of the surface cover are determined. The types of information required to apply this approach are discussed

The corrosion protection of polypyrrol (PPY) and polyaniline (PANI) coatings electrochemically deposited with and without polyvinyl alcohol (PVA) as adhesive onto 304 type stainless steel has been evaluated using electrochemical techniques. Environment included 0.5 M H{sub 2}SO{sub 4} at 60 C whereas employed techniques included potentiodynamic polarization curves (PC), linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) measurements. Results showed that the free corrosion potential, of the substrate, E{sub corr}, was made more noble up to 500 mV with the polymeric coatings. The corrosion rate was lowered by using the polymers, but with the addition of PVA, it was decreased further, one order of magnitude for PPY and up to three orders of magnitude for PANI. Impedance spectra showed that the corrosion mechanism is under a Warburgh-type diffusional process of the electrolyte throughout the coating, and that the uptake of the environment causes the eventual failure of the coating corroding the substrate.

Full Text Available This Opinion paper briefly summarizes the views of the authors on the directions of research in the area of plant protection chemistry. We believe these directions need to focus on (1 the discovery of new pesticide active ingredients, and (2 the protection of human health and the environment. Research revenues are discussed thematically in topics of target site identification, pesticide discovery, environmental aspects, as well as keeping track with the international trends. The most fundamental approach, target site identification, covers both computer-aided molecular design and research on biochemical mechanisms. The discovery of various classes of pesticides is reviewed including classes that hold promise to date, as well as up-to-date methods of innovation, e.g. utilization of plant metabolomics in identification of novel target sites of biological activity. Environmental and ecological aspects represent a component of increasing importance in pesticide development by emphasizing the need to improve methods of environmental analysis and assess ecotoxicological side-effects, but also set new directions for future research. Last, but not least, pesticide chemistry and biochemistry constitute an integral part in the assessment of related fields of plant protection, e.g. agricultural biotechnology, therefore, issues of pesticide chemistry related to the development and cultivation of genetically modified crops are also discussed.

This is why we wanted to see what the environment is important for managers on companies in Romania, the company's CSR policy. In the literature the definition of social responsibility and ways to implement this in practice are often encountered. Some authors claim that societal marketing concept has not found its way into the language of business. From here, there were other terms that had a greater impact on the business environment such as social responsibility. Increasing the company's impact on the environment, the pressure exerted by stakeholders, and identifying positive elements of socially responsible approach have been the main stimulus for development of social responsibility. From that a lot of studies on academic and commercial problem. And the present study fit the same line we conducted a research on 50 companies,it was an exploratory research.

The study is the only planning document that is required for the entire area of a district. It outlines directions of spatial policy and spatial development. Detailed investigations encompassed nine functionally diverse rural districts in SE Poland. The objective was to assess the description of environmental determinants and the problems of natural resources protection presented in the studies. The adequacy of the adopted approach to the subject matter and its correlation with spatial development directions were analysed. The analysed studies usually provide an exhaustive description of (a natural resources and the nature conservation system along with restrictions in environment use, and (b the problem of raw materials. Not all studies, however, highlight the local, very often unique characteristics of the natural environment. Natural hazards are marginalized in some studies. There is also a lack of concrete solutions for the protection of space and improvement of spatial order.

Full Text Available Soundscape, as urban noise is termed, is essentially a qualitative approach which aims to discover ways to improve the “sonic environment”. A possible analogy can be assumed for the acoustic quality of some types of covered spaces which have a function similar to urban spaces. Furthermore, it can be proposed that such covered spaces may have a specific, distinct and recognizable sound environment - hence, a “soundscape” occurs which is created both by the architecture and the sound sources. This study takes a further step in suggesting that the acoustic comfort or sound quality of these spaces cannot be sufficiently dealt with via noise parameters. This paper aims to show the possibility of evaluating the acoustical quality of covered spaces, such as shopping centers, through soundscape studies. The formation of streets is the basic spatial design concept that connects open and closed shopping areas. For this reason the researchers chose to study a modern and an historical shopping center and a modern and a traditional street, both of which have shopping as a basic function, The soundscapes of these open and closed shopping areas were determined by soundwalks and listening tests. The objective and subjective findings of this study showed that covered shopping areas have a specific soundscape that can be evaluated by the soundwalk method regardless of whether the environment is open or covered.

Current wildlife dose assessment models adopt simplistic approaches to the representation of animal-environment interaction. The simplest approaches are to assume either that environmental media (e.g. soil, sediment or water) are uniformly contaminated or relating organism exposure to activity concentrations in media collected at the point of sampling of the animal. The external exposure of a reference organism is then estimated by defining the geometric relationship between the organism and the medium. For example, a reference organism within the soil would have a 4p exposure geometry and a reference organism on the soil would have a 2p exposure geometry. At best, the current modelling approaches recognise differences in media activity concentrations by calculating exposure for different areas of contamination and then estimating the fraction of time that an organism spends in each area. In other fields of pollution ecology, for example wildlife risk assessment for chemical pollution, more advanced approaches are being implemented to model animal-environment interaction and estimate exposure. These approaches include individual-based movement modelling and random walk modelling and a variety of software tools have been developed to facilitate the implementation of these models. Although there are more advanced animal-environment interaction modelling approaches that are available, it is questionable whether these should be adopted for use in environmental radiation protection. Would their adoption significantly reduce uncertainty within the assessment process and, if so, by how much? These questions are being addressed within the new TREE (TRansfer - Exposure - Effects) research programme funded by the United Kingdom Natural Environment Research Council (NERC) and within Working Group (WG) 8 of the International Atomic Energy Agency's MODARIA programme. MODARIA WG8 is reviewing some of the alternative approaches that have been developed for animal-environment

Full Text Available The outdoor open space is used for various purposes, e.g., to walk, rest, talk, meet, study, exercise, play, perform, eat, and drink. Therefore, it is desirable to provide various thermal environments according to users’ needs and their actual conditions. In this study, the radiation environment was evaluated, focusing on ground cover materials and solar radiation shading, through the examination on the redevelopment buildings in front of Central Osaka Station. The spatial distribution of solar radiation shading was calculated using ArcGIS and building shape data. Surface temperatures on the ground and wall are calculated based on the surface heat budget equation. MRT (Mean Radiant Temperature of the human body is calculated assuming that the human body is a sphere. The most dominant factor for the radiant environment is solar radiation shielding and the next is the improvement of surface cover. It is difficult to make SET* (Standard new Effective Temperature comfortable in the afternoon by both solar radiation shielding and improved surface cover because the air temperature is too high on a typical summer day (August. However, particularly in Rooftop Gardens and Green Garden, because the areas of shade grass and water are large, there are several places where people do not feel uncomfortable.

The use of gamma radiation in the preservation of the cultural environment, and in particular art objects, is examined. In each branch, the present status of research on, and its application to, the treatment of art objects is described. Two major applications - disinfection and consolidation - are reviewed: (1) Disinfection: The destruction by gamma irradiation of xylophagous insects and of fungi which contaminate paintings, pictorial documents and mummies, is discussed. The effect of gamma-rays on the constituent materials of the infected objects is examined. (2) Consolidation: this process represents an extrapolation to the preservation of cultural objects of research performed over the last 20 years with the aim of improving the mechanical properties of porous materials (by impregnation of the material in a vacuum by a liquid plastic substance which is polymerized by radiation in situ). This technique is currently being used to treat ''uncoated'' wooden objects and, to a more limited extent, ''coated'' wood (polychromy and gilt wood), depending on the fragility of the covering. With regard to stone materials, the enhancement of the mechanical properties of a limestone impregnated with a styrene-polyester resin is described; this resin has been used to treat several sculptures. The use of acrylics and methacrylics has caused some samples to crack during radiation polymerization; theories put forward to explain this phenomenon are discussed. The consolidation of terracotta and bone has also been studied. The consolidation of waterlogged wood (archaeological wood) requires a different impregnation technique (diffusion in liquid). This preservation method has already been used to treat archaeological artifacts. (author)

Ethics, genetics and dynamics: an emerging systematic approach to radiation protection of the environment

International Nuclear Information System (INIS)

Pentreath, R.J.

2004-01-01

There is now a general consensus of opinion that an explicit approach is necessary to demonstrate radiation protection of the environment, and that this approach needs to be developed in a systematic way. The framework that is emerging links ethical and moral issues (anthropocentric, biocentric, and ecocentric) to broad-based principles and objectives of environmental protection (sustainable development, maintaining biological diversity, and habitat protection) and then links these, in turn, to the needs of current environmental management practices, such as environmental exploitation, pollution control, and nature conservation. The relevance of this to radiation is that its effects (such as causing early mortality, morbidity, reduced reproductive success, as well as resulting in observable (scorable) cytogenetic damage) are those that may have a bearing on these same environmental management practices. The devise that would appear to be most useful to bridge the gap between our disparate data on radiation effects and the needs of environmental management, is that of adding to the concept of Reference Man in the shape of a small set of Reference Animals and Plants. This approach has now been adopted by the ICRP, adding new dynamics--the motive forces, both moral and physical--to the subject. The way is now clear for rapid progress to be made on a number of fronts

Scale dependency in effectiveness, isolation, and social-ecological spillover of protected areas.

Protected areas are considered vital for the conservation of biodiversity. Given their central role in many conservation strategies, it is important to know whether they adequately protect biodiversity within their boundaries; whether they are becoming more isolated from other natural areas over time; and whether they play a role in facilitating or reducing land-cover change in their surroundings. We used matching methods and national and local analyses of land-cover change to evaluate the combined effectiveness (i.e., avoided natural-cover loss), isolation (i.e., changes in adjacent areas), and spillover effects (i.e., impacts on adjacent areas) of 19 national parks in South Africa from 2000 to 2009. All parks had either similar or lower rates of natural-cover loss than matched control samples. On a national level, mean net loss of natural cover and mean net gain of cultivation cover decreased with distance from park boundary, but there was considerable variation in trends around individual parks, providing evidence for both increased isolation and buffering of protected areas. Fourteen parks had significant positive spillover and reduced natural-cover loss in their surroundings, whereas five parks experienced elevated levels of natural-cover loss. Conclusions about social-ecological spillover effects from protected areas depended heavily on the measures of land-cover change used and the scale at which the results were aggregated. Our findings emphasize the need for high-resolution data when assessing spatially explicit phenomena such as land-cover change and challenge the usefulness of large-scale (coarse grain, broad extent) studies for understanding social-ecological dynamics around protected areas. © 2016 Society for Conservation Biology.

Autumn cover crops and green manures: environment protection and agronomic interest. Due to the evolution of the environmental policy, practice of green manure cropping has been replaced by autumn cover crops in order to take up nitrate residues of the soil. These crops (mustard, phacelia, rye-grass, rye) show a high ability to take up N (sometimes more than 100 kg N.ha-1), leading to a decreasing threat for nitrate leaching. Such an ability is however related to species, but also to cropping...

Protected areas (PAs) cover about 22% of the conterminous United States. Understanding their role on historical land use and land cover change (LULCC) and on the carbon cycle is essential to provide guidance for environmental policies. In this study, we compiled historical LULCC and PAs data to explore these interactions within the terrestrial ecosystem model (TEM). We found that intensive LULCC occurred in the conterminous United States from 1700 to 2005. More than 3 million km2 of forest, grassland and shrublands were converted into agricultural lands, which caused 10,607 Tg C release from land ecosystems to atmosphere. PAs had experienced little LULCC as they were generally established in the 20th century after most of the agricultural expansion had occurred. PAs initially acted as a carbon source due to land use legacies, but their accumulated carbon budget switched to a carbon sink in the 1960s, sequestering an estimated 1,642 Tg C over 1700–2005, or 13.4% of carbon losses in non-PAs. We also find that PAs maintain larger carbon stocks and continue sequestering carbon in recent years (2001–2005), but at a lower rate due to increased heterotrophic respiration as well as lower productivity associated to aging ecosystems. It is essential to continue efforts to maintain resilient, biodiverse ecosystems and avoid large-scale disturbances that would release large amounts of carbon in PAs.

Radiation protection aspects of the trafficking radionuclides contaminated metal scrap

International Nuclear Information System (INIS)

Prouza, Z.

1999-01-01

This paper covers the legal base of the release in the environment of radionuclides containing materials and the radiation protection aspects of trafficking in radionuclides contaminated materials. Materials, substance and objects containing radionuclides or contaminated by them may be released into the environment, if they do not exceed values authorized by SONS (State Office of Nuclear Safety). Legislative measures should be taken against illicit trafficking of the nuclear material in all the areas. The creation of a sophisticated system for the control and regulation of all important radionuclides released into the environment should be based on the radiation protection limits, constraints, reference and exemption levels which are introduced in the legislative documents; the strong supervision of producers and users of the sealed sources by SONS side, in addition to the requirements of the licensing process of their sources; a complete data-base and information exchange system related to illicit trafficking in contaminated material; in this system all the authorities with jurisdiction should be involved. The responsibilities of the persons involved in metal scrap trafficking should include arrangement of appropriate monitoring, rules for transport of the metal scrap, an adequate measuring system to monitor metal scrap including monitoring to prevent processing or smelting of the radioactive material, control measures, etc. All of the above items of legislation are an important challenge for the Czech Republic.

Full Text Available Plastic covering is used worldwide to protect crops against damaging growing conditions. This agricultural practice raises some controversial issues. While it significantly impacts on local economic vitality, plasticulture also shows several environmental affects. In the Apulia Region (Italy the wide-spreading of artificial plastic coverings for vineyard protection has showed negative consequences on the hydrogeological balance of soils as well as on the visual quality of rural landscape. In order to monitor and manage this phenomenon, a detailed site mapping has become essential. In this study an efficient object-based classification procedure from Very High Spatial Resolution (VHSR true color aerial data was developed on eight test areas located in the Ionian area of the Apulia Region in order to support the updating of the existing land use database aimed at plastic covered vineyard monitoring.

Environmental radiation protection - a brief history

International Nuclear Information System (INIS)

Zapantis, A.P.

2003-01-01

The effects of ionising radiation on man has been studied intensely for decades, and the system of radiation protection for man has been continually refined in the light of those studies. That system assumes that if man is protected, non-human biota at the species level will also be adequately protected. However, an increasing recognition of the need to protect the environment, and international agreements signed in 1992, have resulted in that paradigm being questioned, with the onus shifting slowly towards demonstrating that the environment is protected. Further, radiation protection agencies and environmental protection agencies around the world have now started considering the issue of developing a system of radiation protection for the environment. The International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA) are also active in this area. The purpose of this paper is to briefly outline some of the issues confronting environmental and radiation protection specialists, and to mention some of the initiatives being taken by the international community to resolve those issues

Non-radiological factors and decision making on the radiological protection of the environment

International Nuclear Information System (INIS)

Simcock, A.

2002-01-01

'Non-radiological factors' can cover both physical and non-physical issues. As far as physical issues are concerned, the appropriate course is not to forget that radioactive substances have to be considered in the same way as other substances in respect of their non-radioactive properties. 'Damage to amenities' and 'interference with legitimate uses of the sea' are long-standing descriptions of the non-physical aspects of marine pollution and degradation. A framework for a taxonomy of the interests involved in such aspects is suggested, using the three dimensions of the degree of linkage to the marine environment, the nature of the interaction with the marine environment, and the economic nature of the interest concerned. Questions of remoteness also arise. A multi-dimensional analysis of the risks to the interests concerned is suggested. The dimension of 'public response' is particularly significant for the non-physical aspects of marine pollution and degradation. This dimension is complex, being influenced by 'fright factors' and subject to media amplification. These influences can include special local economic circumstances and past experiences. Finally, the process for integrating physical and non-physical factors is examined. Early consideration is recommended of how to achieve a transparent presentation of the issues and the way in which decisions are to be taken. (author)

Forecasting land cover change impacts on drinking water treatment costs in Minneapolis, Minnesota

Science.gov (United States)

Woznicki, S. A.; Wickham, J.

2017-12-01

Source protection is a critical aspect of drinking water treatment. The benefits of protecting source water quality in reducing drinking water treatment costs are clear. However, forecasting the impacts of environmental change on source water quality and its potential to influence future treatment processes is lacking. The drinking water treatment plant in Minneapolis, MN has recognized that land cover change threatens water quality in their source watershed, the Upper Mississippi River Basin (UMRB). Over 1,000 km2 of forests, wetlands, and grasslands in the UMRB were lost to agriculture from 2008-2013. This trend, coupled with a projected population increase of one million people in Minnesota by 2030, concerns drinking water treatment plant operators in Minneapolis with respect to meeting future demand for clean water in the UMRB. The objective of this study is to relate land cover change (forest and wetland loss, agricultural expansion, urbanization) to changes in treatment costs for the Minneapolis, MN drinking water utility. To do this, we first developed a framework to determine the relationship between land cover change and water quality in the context of recent historical changes and projected future changes in land cover. Next we coupled a watershed model, the Soil and Water Assessment Tool (SWAT) to projections of land cover change from the FOREcasting SCEnarios of Land-use Change (FORE-SCE) model for the mid-21st century. Using historical Minneapolis drinking water treatment data (chemical usage and costs), source water quality in the UMRB was linked to changes in treatment requirements as a function of projected future land cover change. These analyses will quantify the value of natural landscapes in protecting drinking water quality and future treatment processes requirements. In addition, our study provides the Minneapolis drinking water utility with information critical to their planning and capital improvement process.
