This paper presents the precise method to estimate the dependence of linear and mass attenuation coefficients of gamma rays on concentration of Manganese (II) chloride (MnCl2). The experiment was done using GSpec gamma spectroscopy system. The GSpec consists 2‖x 2‖ NaI (Tl) detector with Multichannel analyzer (MCA). The GSpec has built in 14 Pin PMT base.The GSPEC is pc based Gamma Ray Spectros...

Soil contamination may occur in the upcoming decommissioning activities of TRIGA2000 Reactor. Measurement contaminant radioactivity, which can be performed using single-channel spectroscopy, is required soil decontamination processes. This research develops a timer/counter system for spectroscopy microcontroller. The performance ATMega328P microcontroller Timer/Counter on Arduino has been teste...
