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.

Assessment of ¹³⁷Cs in the Environment of Hetauda City, Nepal by In-Situ Gamma Ray Spectrometry

Atom Indonesia, 2023
A significant amount of 137Cs radioactive fallout have been spread in the atmosphere due to nuclear weapon testing and nuclear reactor disasters. This fallout eventually settles on the Earth's surface, and because 137Cs has a long half-life, it remains ...

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

Nuclear 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.

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%).

Source and LVis based coincidence summing correction in HPGe gamma-ray spectrometry

Nuclear Engineering and Technology, 2022
The activity of gamma-ray emitting nuclides is calculated assuming that each gamma-ray is detected individually; thus, the magnitude of the coincidence summing signal must be considered during activity calculations.

Insights into Gamma-Ray Spectrometry of Building Stones in the North Temple of the Great Ball Court, Archaeological Zone of Chichen Itza, Mexico

Buildings
Non-destructive tests are especially useful for the assessment of building stones and their deterioration in built cultural heritage. Gamma-ray spectrometry is a non-destructive test that has not been applied extensively in these types of constructions ...
