[The levels of soil pollution with plutonium isotopes in the Bryansk Oblast (following the accident at the Chernobyl Atomic Electric Power Station)].

The estimates of plutonium concentration in soils of Western regions of Bryansk (Krasnogorsky, Novozybkovsky, Zlynkovsky and Klintsovsky) are presented. The levels of soil contamination with plutonium within the regions examined vary by 4-5 times, although no definite geographical direction of pollution intensity within the territory examined is noted. The cumulative concentration of isotopes (238Pu, 239Pu, and 240Pu) varies within 21-112 Bq/kg.
