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

Arhiv 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.

Optimization of the gamma-ray spectrometry counting time based on uncertainties of radionuclides concentration in samples

Brazilian Journal of Radiation Sciences, 2020
This paper aims to propose an easy and fast method of optimization of the gamma-ray spectrometry counting time in determining natural radionuclides (Pb-210, Pb-212, Pb-214, Bi-212, Bi-214 and Ac-228) in order to minimize uncertainties in the ...

Fission studies by prompt gamma-ray spectrometry

EPJ Web of Conferences, 2015
The feasibility of retrieving accurate fission observables with a Ge-detector array around a fissile target placed in a cold neutron beam was tested. In three measurement campaigns performed at ILL with the EXILL setup, 235U and 241Pu targets were placed

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

Brazilian 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%).
