An Aerial Gamma Ray Survey of the Surrounding Area of Sizewell Nuclear Power Station [PDF]

, 1997
<p>An airborne gamma ray survey of the surroundings of the Sizewell nuclear power station was conducted to define the present levels of radiation background for reference purposes. A twin engine helicopter fitted with a high volume NaI detector and

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 ...

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%).

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.

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 ...

The effect of flight line spacing on radioactivity inventory and spatial feature characteristics of airborne gamma-ray spectrometry data [PDF]

, 2008
Airborne Gamma Spectrometry (AGS) is well suited to the mapping of radioactivity in the environment. Flight parameters (e.g. speed and line spacing) directly affect the rate of area coverage, cost, and data quality of any survey.

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.
