| In the present work gamma attenuation behavior of some commonly used commercial stainless steels and boron steels were investigated. 303, 304, 310, 316, 430 stainless steels and ZF7B, 27M12C5B, 30MNB5 boron steels were studied against Cs-137 and Co-60 gamma radioisotopes. The linear and mass attenuation coefficients of the samples were measured by using gamma transmission technique. Mass attenuation coefficients were compared with the theoretical values which were calculated by using XCOM computer code. Theoretical and experimental mass attenuations were closed to each other. In addition half-value thickness (HVT) values of the samples were calculated and compared with the results of lead (Pb). European Union has published the directive in 2002 and recast in 2011 about Restriction of Some Hazardous Substances (RoHS) which included Pb. This study shows that 303, 304, 310 and 316 stainless steels and ZF7B, 27M12C5B, 30MNB5 boron steels are some of the candidate materials for using in gamma shielding applications instead of lead. |
