Uptake of radionuclides by plants after the Chernobyl accident.
Gamma-radioactivity of a wide variety of plant samples was measured. Measurements showed that radioactivity in plants depended on the area of surface exposed, the developmental season of the plants, and on the external morphology of their above-ground parts. Autoradiographs on several plants showed the presence of radioactivity in certain spots (hot spots) which were distributed randomly on the surface of the plants and differed in size and activity.
