One of the sources of environment components radioactive contamination is underground nuclear explosions that were conducted for “peaceful” purposes in the second half of the XX century.
The main source of radionuclides intake into surface food chains is soil. As a result of underground explosions, radionuclides infilter soil, enter biogeochemical migration cycles, and become new soil components.
The authors of the article have carried out a research of the content of the technogenic radionuclides in the soil of the underground nuclear explosion called area “Tavda”. The authors have presented the analysis of the technogenic radionuclides contamination according to compass points within the distance of 100, 200, 300, 400 and 500 meters from the epicentre of the explosion, patterns of vertical distribution of strontium-90 and cesium-137 are also considered.
The obtained data, taking into account radionuclides half-life, show that the radiation situation in the epicentre of the explosion remains high.
