摘要：
The cumulative deposition of Pu-238 and Pu-239,Pu-240 by the end of 1990 in grassland, undisturbed for the last 40 years, was determined at 50 sites in Czechoslovakia. The cumulative deposition of Pu-238 and Pu-239,Pu-240 ranged from approximate to 0.5 to 6.2 and from 10.2 to 108.2 Bq m(-2), respectively. The mean value of the cumulative deposition of Pu-238 and Pu-239,Pu-240 were 1.7 and 49.3 Bq m(-2), respectively. No significant contribution to the cumulative deposition of Pu-238 and Pu-239,Pu-240 originating from the Chernobyl accident was found at any site and no significant decrease of Pu-239,Pu-240 at sites in the northwest parts of the Czech Republic with long-term, high incidence of acid rain was found either.
