Abstract

In this study, radiation shielding performance of pure Lead Sheets were carried out by using new X-ray transmission set up. Diagnostic x-rays from 50 kVp to 110 kVp were applied in the experiments. Experimental set up was designed according to narrow beam geometry conditions of IEC 61331-1:2014 standard. Pure Lead sheets (99.99 % purity) having different thicknesses (0.05-0.5 mm, 0.05 mm steps), were performed against diagnostic x-rays. Radiation attenuation percentages were carried out for each xray peak tube voltages from 50 kVp to 110 kVp with 10 kVp steps. Radiation shielding percentages of the lead sheet for the studied x-ray peak tube voltage were in the range of 50.8-99.7 %. X-ray shielding percentages of commonly used Lead thicknesses were compared with the literature. The radiation shielding percentages of the samples were in a good agreement with the literature. The average of difference percentages of the study with the literature was 0.76 %. 0.25, 0.35 and 0.5 mm Lead thicknesses have 90.3 % , 94.7 % and 97.2 % shielding performance against 90 kVp, respectively.
