摘要：
The concentration of the plutonium isotopes Pu-238 and Pu-239+240 in the surroundings of the research reactor was measured by application of a very sensitive and selective radioanalytical procedure for the determination of plutonium in soils and plants, including lichens and mosses as bioindicators. All measured concentrations are in the range of variation of the global contamination with plutonium caused by fallout of atmospheric nuclear weapon tests and burning of satellites in the atmosphere. An additional contamination by plutonium isotopes due to discharges from the reactor in the past is not detectable.
