Application of a new in situ calibration technique for gamma spectrometry and comparison of in situ and laboratory measurements

open access: yesArhiv za Higijenu Rada i Toksikologiju, 2021
In situ gamma ray spectrometry was developed to quickly measure large areas of land following nuclear accidents. However, a proper calibration of detectors for in situ measurements is a long and complicated process.

Pile-up correction for coincidence counting using a CAEN 1724 digitizer

open access: yesBrazilian Journal of Radiation Sciences, 2019
In conventional gamma-ray spectrometry, the probability of pile-up effects is considered to be proportional to the dead-time, and is usually neglected for low dead-times (below 4-5%).

Non-destructive technique to verify clearance of pipes [PDF]

open access: yesNuclear Technology and Radiation Protection, 2010
A semi-empirical, non-destructive technique to evaluate the activity of gamma ray emitters in contaminated pipes is discussed. The technique is based on in-situ measurements by a portable NaI gamma ray spectrometer.
