The purpose of this study is to investigate photon attenuation parameters of Colombia Resin-39 (CR-39) lens, which are linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), half value layer (HVL), tenth value layer (TVL), mean free path (MFP), effective atomic number (Zeff) and effective electron density (Neff). MACs were determined theoretically and with simulation in the energy range from 0.01 to 105 MeV. Also, obtained MACs of CR-39 lens were compared with MACs of pure aluminum and lead. Theoretically obtained Zeff values were compared with Zeff results obtained by the computer software.The results of this study are; a) the theoretically obtained MACs values are in agreement with MACs obtained results from simulation software, b) the theoretically obtained Zeff values are in agreement with Zeff obtained by the computer software c) the MACs of CR-39 lens are much lower than MACs of pure lead whereas there is not too much differences between MACs of CR-39 and pure aluminium d) the HVLs, TVLs and MFPs rise with increasing photon energy while the LACs and MACs reduce with increasing photon energy.

“…Linear attenuation coefficient (LAC) (µ), half value layer (HVL), tenth value layer (TVL), and mean free path (MFP) has a significant role to define the effects of gamma radiations for the materials (Tekin et al, 2017). The various investigators (Abbasova et al, 2019;Abutalib and Yahia, 2017;Badran et al, 2017;Kaçal et al, 2018;Köksal et al, 2019) have focused the attenuation parameters of some materials. When considering the former works, the elemental analysis, structural property, mechanical facilities, adsorbing and corrosion were studied by different investigator for some kinds of hydroxyapatite (Ciobanu et al, 2011;Fujii et al, 2006;Koksal et al, 2019a;Stipniece et al, 2018).…”

This investigation focuses on the gamma ray attenuation parameters of natural animal bone, iron, cobalt, copper and zinc doped Nano hydroxyapatite artificial bone powders and pure hydroxyapatite. The present specimens were excited by means of gamma ray photons with 59.5 keV energy radiated from a 241-Amercium annular radioactive source with 50 mCi activity by means of narrow beam transmission geometry. The transmitted gamma-rays were counted with using Ultra Low Energy Germanium (Ultra-LEGe) detector with a resolution 150 eV at 5.95 keV. The gamma-ray attenuation characteristics such as mass attenuation coefficient (MAC) (µ/ρ), linear attenuation coefficient (LAC) (µ), half value layer (HVL), tenth value layer (TVL) and mean free path (MFP), which has a significant role in the attenuation studies, are also calculated. The values obtained were checked with the predicted values from the XCOM NIST. The results show that the attenuation data of the metal-doped hydroxyapatite synthetic bone dust is very close to the value of the natural animal bone.

Polymeric composite materials for radiation shielding: a review

et al. 2021

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.
