Pilot survey of soil contamination 30 years after Chernobyl

Popis výsledku v původním jazyce

The study was carried out in cooperation with the State Institute for Radiation Protection of the Czech Republic as a pilot project for the 137Cs Residue after the Chernobyl accident. The prediction of the development of the radiation situation can be based on an extensive soil survey. The current contamination of the soil with 137Cs was contributed by 2 sources: the nuclear weapons tests in the atmosphere that peaked in the 1960s and the Chernobyl accident. Surface contamination in the CR from the nuclear weapons tests in the 1960s was similar in size to the Chernobyl accident, however due to the time lag between both events, the contribution of Chernobyl contamination may currently be higher. Both contributions are not easily distinguishable. The selection of soil sampling sites was based on the 137Cs Czech soil contamination map attributed to the Chernobyl accident created by the State Institute for Radiation Protection of the Czech Republic shortly after the Chernobyl accident in 1986. The contamination of the upper layer of the soil was supposed to be dominated by the Chernobyl accident. The heterogeneous distribution of 137Cs and other radionuclides after the Chernobyl accident in the Czech Republic was caused by the coincidence of local precipitation with the passage of a contaminated cloud (several passages in different directions). Higher values were found in the area of the former North Moravian Region and the South Bohemian Region. A total of 66 samples of soils from different localities in the Czech Republic were processed and the results compared with the situation in 1986.
