Radioactive minerals prospecting, geological survey, radioactive geological survey
Radioactive environmental assessment, radioactivity monitoring;
Radioactive elements quantitative analysis of content, specific activity, internal exposure, external exposure
Description
This portable multi-channel Gamma-Ray spectrometer is kind of new type radioactive detection equipment, it can be used either in outdoor or indoor for Gamma energy spectrum analysis. Not only can perform quantitative analysis of the content of U, Th, K in rock, soil, minerals, but also for other radioactive elements(such as 226Ra, 232Th, 40K) and artificial radioactive elements (241Am, 137Cs, 60Co, 192lr) for content, specific activity, internal exposure, external exposure, air absorbed dose etc.
