Laboratory operation during radiation emergency

During radiation emergency, a special operation mode of laboratories of the Radiation Monitoring Network (hereinafter RMN) is expected. The principal factors differing the emergency mode from the normal one are the following: - significantly higher amount of analyzed samples; - high activities of the majority of the samples; - higher risk of personal and equipment contamination; - higher working and psychological demands on laboratory staff. The assuring of the radiation protection requirements of laboratory staff has to be the primary objective, nevertheless the risk of equipment contamination and of samples cross- contamination of course have to be as well taken into consideration. The presentation describes the experience of the RMN Central Laboratory of the National Radiation Protection Institute in Prague (SURO) which was obtained during realization of field tests, in which a radioactive matter was released. These tests allow us to evaluate the source term or radioactivity dispersal balance based on various detection methods with the aim to estimate exposure of the afflicted persons. Tests provided to simulate emergency working conditions in Central Laboratory - high number of contaminated samples, which have to be analyzed in a short time (short half-time of used radionuclide 99m Tc) using sophisticated laboratory techniques (gamma spectrometers, aerosols collectors, etc.). The testing shows the availability of the SURO laboratory to work during the radiation emergency and to participate on its determination. The suitable settings and the ideal number of staff have been found. The average analysis time was approximately 1 minute per sample and the sample results were available just a few minutes after the counting. Moreover, the settings avoided any danger and kept both the crew and the samples safe and secure from contamination. (authors)

New approach to radiation monitoring: citizen based radiation measurement

International Nuclear Information System (INIS)

Kuca, P.; Helebrant, J.

2016-01-01

Both the Fukushima Dai-chi NPP accident in Japan in 2011 and the Chernobyl NPP accident in USSR in 1986 similarly to the first one have shown a necessity to find a way how to improve confidence of the public to official authorities. It is important especially in such a case of severe accidents with significant consequences in large inhabited areas around the damaged NPP. A lack of public confidence to officials was caused mostly by rather poor communication between official authorities and the public, as well by restricted access to the information for the public. It may have extremely negative impacts on the public understanding of actual situation and its possible risks, on public acceptance of necessary protective measures and participation of the public in remediation of the affected areas. One of possible ways to improve the situation can be implementation of citizen radiation monitoring on voluntary basis. Making sure, the official results are compatible with public self-measured ones, the public probably has more confidence in them. In the Czech Republic the implementation of such an approach is tested in the framework of security research founded by the Czech Ministry of the Interior - the research project RAMESIS solved by SURO.

HPGe detector shielding adjustment

International Nuclear Information System (INIS)

Trnkova, L.; Rulik, P.

2008-01-01

Low-level background shielding of HPGe detectors is used mainly for environmental samples with very low content of radionuclides. National Radiation Protection Institute (SURO) in Prague is equipped with 14 HPGe detectors with relative efficiency up to 150%. The detectors are placed in a room built from materials with low content of natural radionuclides and equipped with a double isolation of the floor against radon. Detectors themselves are placed in lead or steel shielding. Steel shielding with one of these detectors with relative efficiency of 100% was chosen to be rebuilt to achieve lower minimum detectable activity (MDA). Additional lead and copper shielding was built up inside the original steel shielding to reduce the volume of the inner space and filled with nitrogen by means of evaporating liquid nitrogen. The additional lead and copper shielding, consequent reduction of the inner volume and supply of evaporated nitrogen, caused a decrease of the background count and accordingly MDA values as well. The effect of nitrogen evaporation on the net areas of peaks belonging to radon daughters is significant. The enhanced shielding adjustment has the biggest influence in low energy range, what can be seen in collected data. MDA values in energy range from 30 keV to 400 keV decreased to 0.65-0.85 of original value, in energy range from 400 keV to 2 MeV they fell to 0.70-0.97 of original value. (authors)

Strontium-90 in milk and mixed diet in the Czech Republic

2014-01-01

Among various activities of National Radiation Protection Institute (SURO) monitoring of radionuclides in environment and food chain plays an important role. The monitoring takes place in frame of Czech Radiation Monitoring Network (RMN). Determinations of 90 Sr are performed according to the monitoring schedule of RMN. Strontium-90 was released into environment during the tests of nuclear weapons in the fifties and sixties of XX. century and to some extent in 1986 owing to the Chernobyl accident. Strontium is a chemical analogue of calcium and accordingly when entering a mammal body, it behaves very much like calcium. A large portion of the strontium will accumulate in bone and like calcium it transfers to milk. Since the Sr uptake by the human body from milk is an important pathway for radiostrontium incorporation, milk and milk powder are good indicators of 90 Sr content in human diet. Along with milk and milk powder, mixed diet samples composed of representative locally purchased food items according to food consumption statistics are also analysed for 90 Sr.The analyses are made using oxalate precipitation method, when interfering radionuclides are removed by precipitation scavenging and after its ingrowth 90 Y is separated and repeatedly measured by gas flow proportional counter. Strontium-90 activity is calculated as equal to 90 Y activity in equilibrium. Time evolution of 90 Sr activities in milk in Northern Moravia region (1988 present) and in Prague (1965 - present), in milk powder from the regions of the Czech Republic and in the mixed diet samples from the whole republic is presented on the poster. A very small increase due to the Chernobyl accident can be seen in milk. After the ban of atmospheric tests the level of 90 Sr has steadily been falling. The decrease is caused by radioactive decay and migration of the radionuclide in the environment. Due to this decrease activity concentrations in many samples have recently fallen under minimum significant

Centrum Vyzkumu Rez (CVR) is research and development Company situated in Czech Republic and member of the UJV group. One of its major fields is material research for Generation IV reactor concepts, especially supercritical water-cooled reactor (SCWR), very high temperature/gas-cooled fast reactor (VHTR/GFR) and lead-cooled fast reactor (LFR). The CVR is equipped by and is building unique experimental facilities which simulate the environment in the active zones of these reactor concepts and enable to pre-qualify and to select proper constructional materials for the most stressed components of the facility (cladding, vessel, piping). New infrastructure is founded within the Sustainable Energy project focused on implementation the Generation IV and fusion experimental facilities. The research of SCWR concept is divided to research and development of the constructional materials ensured by SuperCritical Water Loop (SCWL) and fuel components research on Fuel Qualification Test loop (SCWL-FQT). SCWL provides environment of the primary circuits of European SCWR, pressure 25 MPa, temperature 600 deg. C and its major purpose is to simulate behavior of the primary medium and candidate constructional materials. On-line monitoring system is included to collect the operational data relevant to experiment and its evaluation (pH, conductivity, chemical species concentration). SCWL-FQT is facility focused on the behavior of cladding material and fuel at the conditions of so-called preheater, the first pass of the medium through the fuel (in case of European SCWR concept). The conditions are 450 deg. C and 25 MPa. SCWL-FQT is unique facility enabling research of the shortened fuel rods. VHTR/GFR research covers material testing and also cleaning methods of the medium in primary circuit. The High Temperature Helium Loop (HTHL) enables exposure of materials and simulates the VHTR/GFR core environment to analyze the behavior of medium, especially in presence of organic compounds and
