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.

“…Black to brown colours of obsidians are caused by iron and other transition elements of ingredients [9]. Due to the great interest in such structures, obsidians were studied widely before [7,[10][11][12][13]. Aygun et al reported the spectroscopic features and radiation shielding potentials of four obsidians from different regions in Turkey [7].…”

Obsidians are naturally occurring structures which have great interest and are widely used in engineering, nuclear and medical applications. These glassy volcanic rocks are formed as a result of volcanic activity and lava eruptions. In the present study, it is aimed to determine the radiation protection parameters of obsidians with different colors in order to examine the radiation shielding capabilities of the samples. The parameters were determined in the range of 4keV-100 GeV photon energies by using Phy-X/PSD code. In order to make a meaningful analyze for the radiation shielding potentials of the obsidians, the calculated mass attenuation and linear attenuation coefficients were compared with ordinary concrete which can be widely used as shielding material in the nuclear application.
