Abstract
Shielding aprons were produced using microlead with chlorophyll, which is a viable alternative to the widely used sheet lead aprons for shielding against medical radiation. A study was conducted to examine the effectiveness of five types of radiation shielding sheets composed of a blend of microlead and chlorophyll at varying concentrations (50, 100, 150, 200, and 250 wt% with 35 wt%, respectively) with biosilicon as a base. A comparison was made between the transmission dosages of these sheets and a lead standard (commercial shield). The tensile strength was tested when radiation shielding sheets were being made and used the European Standard for Industry test method (IEC 61331-3:2014) for X-ray protection equipment to measure the transmission dosage. and compare the results with radiation transmitted through a lead standard that had different thicknesses (0,05, 0,1, 0,15, 0,2, 0,25, 0,3, and 0,35 mm). These measurements were taken at tube voltages of 30, 60, 90, 120, 150, and 180 kVp. In the results, it was found that using a mixture of 150 % microlead and 35 % chlorophyll worked to measure a dose similar to 0,3 mm of lead. The transmission dose was 13,58 mR and 13,8 mR for sheet lead, and the density of the shield is 1,72 g/cm3. For this reason, it could be used instead of lead sheets, making it a good choice for protecting medical equipment from radiation
