Saturated Solutions

The compounds, Na2B4O7, H3BO3, CdCl2 and NaCl and their solutions, attenuate gamma rays in addition to neutron absorption. These compounds are widely used in shielding of neutron sources, reactor control and neutron converters. Mass attenuation coefficients of gamma related to saturated solutions of the above four compounds, in energies 1172 keV and 1332 keV have been measured by NaI detector and agree very well with the results obtained by Xcom code. Experiment and computation show that, H3BO3 has the highest gamma ray attenuation coefficient among the aforementioned compounds.

Gamma Ray Attenuation

In this study, dependence of gamma-ray absorption coefficient on the size of Pb particle size ranging from 200µm up to 2.5mm, using different weights of each particle size. The results show that gamma-ray attenuation coefficient is inversely proportional with the size of Pb particle size due to the reduction of the spaces between the lead particles.

The purpose of this study was to determine the linear attenuation coefficient, the mass attenuation coefficient, Half Value Layer. Tenth Value Layer and Mean Free Path for four different shielding materials such as aluminium, iron, zirconium and tungsten. By using the gamma-radiation energies emitted from 152Eu, 22Na, 137Cs, and 60Co radioactive sources. For this purpose, the attenuation measurements were performed using NaI(TI) detector. Calculated values of all parameters of the all shielding materials were compared with each other. The results of all presented parameters show that, tungsten has the best radiation shielding compared to other shielding materials. Then, the obtained parameters were compared with the theoretical values.

The Impact

The surrounding conditions of the shielding concrete, (moisture and temperature), affect the water content within it, and therefore, the attenuation coefficient of the concrete. In this study, the impact of changing the amount of water, in four types of local candidate shielding concretes was investigated. The concrete attenuation coefficient of gamma-rays has been identified experimentally and computationally using the MCNP-4C code. The results show a significant decrease in the attenuation coefficient of each the four concrete samples due to the water losses, especially between 20- 100 oC. Acceptable compatibility was noticed between the measured and calculated results of the attenuation coefficient of the studied concrete samples.
