摘要：

A method of autoradiographic investigation of hot particles that have risen into the atmosphere and precipitated on the soil and leaves after the Chernobyl accident of April 1986 has been developed. Particular objects of investigation are the alpha-active radionuclides with their dimensions and activity varying from 0.2 to 200 mum and from 10(-6) to 10(-1) Bq, respectively. BYa-2 nuclear emulsions were used as detectors. The activity distribution function of particles of different dimension, A = f(d), and the leaf contamination density distribution in the vertical profile are obtained.
