Opis:: Concrete is a material which is widely used for neutron shielding in such building constructions as nuclear power stations, particle accelerators and medical hospitals. Concrete is very significant for neutron shielding, because is contains some elements which help to moderate very penetrative fast neutrons. Boron increases the neutron shielding effectiveness of concretes. Boron can be added to concrete in different ways, by addition of boron to the water, used in concrete, or by addition of boron containing natural minerals. In this study, three samples of concrete were produced using B₂O₃ additives material, boron-modified active belite and Portland cement. Neutron absorption coefficients of the produced three different types of concrete samples were obtained through experiments. It is concluded that the addition of boron to concrete is an alternative option to be used for the purposes of neutron shielding.

Opis:: According to developing technology and conditions of modern life, use of radiation is rapidly increased. Unwittingly, our organs and tissues are exposed to radiation continuously. In order to avoid exposure to this radiation, some studies were carried out on protective clothing. In this study, radiation keeping properties of the fabrics coated with barite are examined. Radiation keeping properties were also determined by the method of image processing. After the experiments, it is determined that barite-coated fabrics absorb radiation better than normal fabrics.

Opis:: Since the technology concerning gamma radiation showed a rapid development, it became a necessity to be protected from it. One of the common shielding materials for this purpose is concrete. This study aims to give the effect of pumice rate on the gamma radiation attenuation coefficients of normal concrete (ρ = 2.476 g $cm^{-3}$) containing different rates of pumice mineral. Pumice, for which the Gölcük region in Isparta province is rich, is a volcanic originated spongy and porous mineral. Although it is a light material, it has a high comprehensive strength and heat resistance. So it became a common construction material in buildings. In the study, the variation of attenuation coefficients for concretes of different pumice rates were measured for 662, 1173 and 1332 keV photons using a NaI(Tl) detector. The experimental values were compared with the theoretical ones obtained by XCOM code.

Opis:: Since creation of universe there has been radiation around us and this rate is getting higher with the development of technology. Thus radiation shielding becomes important subject for researcher. Besides normal people especially radiation workers in nuclear facilities need extra protection from radiation. This is vital if we think about any kind of nuclear leakage or nuclear attack, fabric becomes very important. For this purpose, cotton-polyester type of fabric has been coated by barite and gamma ray attenuation efficient has been obtained. The fabric was coated in different rate of barite (0%, 40%, 50% and 60%) in order to test effect of barite rate on the fabric. The measurement has been performed for gamma ray energy of 511, 662, and 835 keV using gamma spectrometer system with NaI(Tl) detector. It was found that the attenuation coefficient has increased with the barite coating rate on fabric.

Opis:: It is extremely important to protect the human body from radioactive rays. Protective clothing can be used to absorb radiation because it is preferable to avoid the natural and artificial radiation exposure in our daily lives. There are many different types of fabric, used for clothes. In this study radiation absorbing properties of fabrics, which are widely used in the daily life, such as alpaca-type fabric, cotton fabric, cotton polyester blend fabric, woven dyed fabric and knitted fabric were examined using the image processing method.
