In the work present the results of research of the contamination of the soil with artificial radionuclides at the 4 and 4´A´ test site, where radiological warfare agent program are testing. A modern radiation situation is given in territory. Total number of fields is 30 (5 fields in test site 4 and 25 fields - on 4”A” test site). According to the results of pedestrian beta-radiation’s research create maps of surface contamination. Found that the depth of soil contamination with a specific activity 90Sr 5•104 Bq / kg not exceeding 40 cm. Assessment calculations of radioactive waste (by 90Sr) carried, the total volume amounted is about 105 m3.
