Abstract
In-situ gamma-ray spectrometry can be used as a rapid method for deter mination of the depth distribution of radioactivity in soil. A modifie d in-situ gamma-ray technique is proposed using an absorbing lead plat e placed at various distances in front of the detector in order to alt er its angular response. In this way different layers of soil, where t he registered gamma-rays are emitted from, are scanned. Comparison of the results with laboratory measurements of soil samples for the isoto pes Cs-134 and Cs-137 and for some natural radionuclides shows reasona ble agreement.
