Investigation of Behaviour of Titanium Diboride Reinforced Boron Carbide-Silicon Carbide Composites against Cs-137 Gamma Radioisotope Source by Using Gamma Transmission Technique

Acta Physica Polonica A, 2012
Boron carbide is a material which has wide application areas in industry including nuclear technology. Titanium diboride reinforced boron carbide‐silicon carbide composites were studied for searching of the behaviour against the gamma ray. It has been adopted that depending on their properties such improved materials can be used in nuclear technology ...

Estimating and accounting for 137Cs source burial through In-situ gamma spectrometry in salt marsh environments [PDF]

Journal of Environmental Radioactivity, 1996
The use of in-situ gamma ray spectrometry provides a means of rapidly estimating environmental radioactivity inventories. However, one of the principal limitations of this technique has been the influence of variations in vertical activity distribution on the observed photon fluence.

Path-Planning System for Radioisotope Identification Devices Using 4π Gamma Imaging Based on Random Forest Analysis

Sensors, 2022
We developed a path-planning system for radiation source identification devices using 4π gamma imaging. The estimated source location and activity were calculated by an integrated simulation model by using 4π gamma images at multiple measurement ...

Shielding Effect of Aluminum Against Cs-137 Source, According to Gamma Ray Transmission Technique

Journal of Engineering Technology and Applied Sciences, 2022
In this study the shielding effect of the Aluminum element against radiation is referred to by using the gamma ray transmission technique. Selected gamma-ray source Cesium is monoenergytic and not necessary the activity correction due to its half-life. Absorption caused by aluminum leads to a reduction in the radiation dose exposed. In the literature,
