Application
- TRIO is used to measure:
- activity (specific and volumetric activity) of natural radionuclides (for example 226Ra, 232Th, 40K, 222Rn);
- activity (specific, volumetric activity) of technogenic radionuclides 137Cs, 134Cs, 90Sr, 60Co, 54Co and etc.;
- summary alpha- and beta- activity in water;
- volumetric activity of 222Rn indoors;
- flux density of 222Rn from ground and building structures;
- surface activity of fresh and old radionuclide contamination.
