Abstract:
An investigation of vertical distribution of alpha-emitting nuclides for various types of soils using solid state nuclear track detectors (SSNTD) has been carried out. As SSNTD the DNC-film was used. Experimental system for measurement of total alpha activity in the samples of soils, including devices and equipment for selection of probes, exposition, chemical etching of detectors, automated accounting of tracks has been developed. The method of determination of specific activity of alpha emitting nuclides has been created. A comparison results of measurements with the method pointed out and radiochemical method as well as x-y-spectrometry method has been carried out.
