Summary: In this study, the interaction parameters of gamma-ray, neutron, and charge particles in nine selected thermoplastic polymers with different densities were investigated. The shielding capabilities of these polymers for special radiation shielding applications were evaluated. The results showed that PES had high shielding capability at lower gamma energies. The range of H+ and He++ ions increased with decreasing density of the samples but increased with projectile energies. PES had the highest stopping power at higher electron energies and lowest range at higher electron energies. Composite of PES and PEK is recommended for use in special radiation protection installations and medical radiotherapy.

Summary: In this research, polymers were fabricated by combining polyester, boron oxide, and tellurium oxide. The radiation protection features of these polymers were examined, and the results showed that the linear attenuation coefficient decreased with increasing energy. The addition of tellurium oxide significantly increased the linear attenuation coefficient at low energy. Moreover, the increase in tellurium oxide content led to a decrease in the half value layer and an improvement in the effective atomic number of the polymers.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
