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

open access: yesActa 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 ...

A Portable Three-Layer Compton Camera for Wide-Energy-Range Gamma-ray Imaging: Design, Simulation and Preliminary Testing

open access: yesSensors, 2023
(1) Background: The imaging energy range of a typical Compton camera is limited due to the fact that scattered gamma photons are seldom fully absorbed when the incident energies are above 3 MeV.

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

open access: yesJournal 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.

Radiation damage and recovery properties of common plastics PEN (Polyethylene Naphthalate) and PET (Polyethylene Terephthalate) using a137Cs gamma ray source up to 1.4 Mrad and 14 Mrad [PDF]

open access: yesJournal of Instrumentation, 2016
Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are cheap and common polyester plastics used throughout the world in the manufacturing of bottled drinks, containers for foodstuffs, and fibers used in clothing. These plastics are also known organic scintillators with very good scintillation properties. As particle physics experiments

Gamma ray attenuation for determining soil density: laboratory experiments for Environmental Physics and Engineering courses [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2020
In this paper, we present in details a method for determining the soil density of disturbed samples. The mass attenuation coefficient was also evaluated by using the relation between the number of photon counts and the path length (soil density ...

Research on the relationship between the scattering contribution and physical factors of the reference radiation regulated by ISO 4037-1.

open access: yesPLoS ONE, 2022
In the latest version of ISO 4037-1:2019 standard, the minimum dimension of a gamma radiation reference field was not clearly specified, which makes the construction of a minitype gamma reference radiation field lack of scientific basis.
