Express method of gamma-ray analysis of the soil blocks which have been sampled without a disturbance of the turf layer

Abstract

This paper presents method of gamma-analysis of the soil patterns sampled soon after of nuclear accident. The method does not require of sample preparation and intends for analysis of the soil samples with a non-homogeneous distribution of activity at the depth. Technique of calibration of the detector efficiency is considered, that have been used when soil blocks sampling by means of the non-disturbance method (by rings) after Chernobyl accident were measured.
