Gamma Activity Monitor

Download Datasheet

Atomtex AT1320C highly sensitive selective wide-range spectrometric scintillation gamma activity monitor is designed to work with a personal computer (PC) and measures volumetric (specific) radionuclide activity in 131I, 134Cs, 137Cs, 40K, 226Ra, 232Th samples with 0.5 litre and 1 litre flat containers, and 1 litre Marinelli beaker.

Description

The Atomtex AT1320C is suitable for the measurement of volume activity and specific activity of gamma emitting radionuclides in water, foodstuff, agricultural raw materials and fodder, industrial raw materials, forestry products, building materials, soil and other objects of environment. The measurement process includes preliminary analysis of sample radionuclide composition. Identification results will be used as basis for calculation of sample radionuclide activity. This Gamma activity monitor operates based on the detection unit pulse-height distribution analysis. The data  can be assessed via a PC software designed to control operation modes, view recorded information, calculate gamma radionuclide activity and measurement error for chosen measurement geometry, as well as managing electronic history log of measurement results.
