“…Based on results shown in Table (3), lead had the highest value, while glass had the lowest one. The mass absorption coefficient was calculated by dividing linear attenuation to the material density [8][9][10][11]. Table (3) shows the mass attenuation coefficients for all samples that were close to each other except lead, which had the greatest value.…”

Calculations on shielding are required for the building of a gamma ray radiography exposure room to ensure worker exposure to radiation. A measurement used to evaluate the radiation diffusive and absorption characteristics of a medium is the linear attenuation coefficient ( ). Despite the fact that, as radiation moves through a medium, its absorption is influenced by the wavelength of the radiation as well as the thickness and composition of the medium, the linear absorption coefficient is crucial in the interaction of radiation with matter. This research uses a variety of materials as a shield for a gamma radiation source of emitted by Cs-137. The results obtained using a gamma source with a scintillation counter showed that the Half Value Thickness (HVT) of glass and aluminum were 3.57 cm, and 3.39 cm while for standard materials (concrete, iron, and lead) were 2.98 cm, 1.195 cm, and 0.58 cm respectively.

“…Measurements were made by using a gamma scintillation detector NaI (Tl) and theoretical calculations were done with XCOM. It was determined that it has a better attenuation coefficient than basalt and andesite for these energies (Mavi et al, 2015). In another study, GATE software was used as the Monte Carlo code to calculate the gamma-ray attenuation coefficient of some granite samples at 662 keV, 1173.2 keV and 1332.5 keV photon energies.…”

N THIS study, the gamma-ray attenuation properties of spilitic basalt, andesite, dolomite, limestone and syenite rocks obtained from Trabzon Province and its vicinity have been investigated. The gamma-ray mass attenuation coefficients and radioactivity concentrations of the rocks considered have been determined by using coaxial high purity germanium detector (HPGe) detector system. The capability of andesite by means of gamma-ray shielding for low energy gamma rays has been found highest when it is compared with those of basalt, dolomite, limestone and syenite rocks. In the places where the rocks were extracted, the activities of the natural radioactive elements ( 238 U, 232 Th, 40 K) and artificial radioactive elements ( 137 Cs) have been determined by analyzing the natural radiation concentration on site and using gamma spectroscopic analysis to reveal the presence of radioactivity. The 137 Cs concentration has been found to be below the detection limit. The radioactivity concentrations of 238 U, 232 Th and 40 K have been found to be in acceptable levels. Furthermore, chemical element analyzes have been carried out to determine the content of these rocks precisely. The gamma-ray mass attenuation coefficients of andesite for low energy gamma rays have been found to be highest among those of other rocks considered in this work.

“…The shielding, which is implemented naturally or composite materially, is used widely and effectively for protecting from hazards of radiation. As naturally occurring materials, marbles have been examined widely in terms of gamma attenuation coefficients in literature [2][3][4][5][6] but the survey of Kırklareli marble is absent in literature.…”

Abstract:The total linear and mass attenuation coefficients, half-value and tenth-value thickness of marble samples from Kırklareli Province have been investigated using different gamma ray energies. Three different gamma ray energies one at 661.7 keV from Cs-137 and others at 1173.2 and at 1332.5 keV from Co-60 have been used. The measurements were carried out using a gamma spectrometer containing a NaI(Tl) sintilation detector. Comparison between the results from measurements and from computer code of XCOM has also been performed with the results available in literature. The measurement results obtained from marble disks and tablets of limestone powder were also matched.
