Abstract
On the basis of the work (ground investigations and gamma aerial surveys) carried out jointly by the Rosgidromet organizations and Berezovgeologiya, data on the radiation exposure in Russia were obtained shortly after the accident of April 6, 1993 already. These data were transmitted to interested institutions. The measurements performed on April 11 and 12, 1993 indicated that within the isolines of 10 {mu}R/h a contaminated area of up to 25 km in length and up to 6 km in width extended towards the northeastern direction. Thus, the contaminated area outside of the premises of the combine covered about 100 km{sup 2}. The total amount of radioactive substances in this area was 530 - 590 Ci. Isotope composition of the radioactive trace was determined by ruthenium-103 (1%), ruthenium-106 (31%), zirconium-95 (22%), niobium-95 (45%) and plutonium-239 (0.02%). Contamination heterogeneity is caused by the existence of `hot` particles with an activity of up to 10-11 Ci/particle. In the contaminated area the gamma exposure rate varied between 14 and 42 {mu}R/h at 1 m height, yielding the maximum external radiation dose 100 mrem/year for the population of Georgievka. The Pu-239 inhalation dose of the population of Georgievka when passing the radioactive cloud did not
