“…We measured the lead-equivalent thicknesses of the X-ray protective aprons as figures of merit. Currently, there are various lead-equivalent thickness evaluation methods [ 10 , 11 , 14 ]. We adopted a computational method from an apron attenuation formula [ 14 ], because it is possible to re-inspect lead-equivalent thicknesses easily in all facilities with only aluminum filters, which are easier to acquire than lead filters.…”

“…However, various X-ray energies are used in workplaces [9, 10]. There is also a difference in X-ray attenuation between pure lead and composite materials, which is determined by X-ray energies [9].…”

“…The figures of merit of these protective aprons are commonly expressed as lead-equivalent thicknesses, which are measured only for specific X-ray energies [ 10 , 11 ]. However, various X-ray energies are used in workplaces [ 9 , 10 ]. There is also a difference in X-ray attenuation between pure lead and composite materials, which is determined by X-ray energies [ 9 ].…”

“…There is also a difference in X-ray attenuation between pure lead and composite materials, which is determined by X-ray energies [ 9 ]. Therefore, the X-ray transmission rates of protective aprons, which are often measured at optional energies, differ among manufacturers, despite having the same lead-equivalent thicknesses [ 10 , 11 ].…”

Few practical evaluation studies have been conducted on X-ray protective aprons in workplaces. We examined the effects of exchanging the protective apron type with regard to exposure reduction in experimental and practical fields, and discuss the effectiveness of X-ray protective aprons. Experimental field evaluations were performed by the measurement of the X-ray transmission rates of protective aprons. Practical field evaluations were performed by the estimation of the differences in the transit doses before and after the apron exchange. A 0.50-mm lead-equivalent-thick non-lead apron had the lowest transmission rate among the 7 protective aprons, but weighed 10.9 kg and was too heavy. The 0.25 and 0.35-mm lead-equivalent-thick non-lead aprons differed little in the practical field of interventional radiology. The 0.35-mm lead apron had lower X-ray transmission rates and transit doses than the 0.25-mm lead-equivalent-thick non-lead apron, and each of these differences exceeded 8 % in the experimental field and approximately 0.15 mSv/month in the practical field of computed tomography (p < 0.01). Therefore, we concluded that the 0.25-mm lead-equivalent-thick aprons and 0.35-mm lead apron are effective for interventional radiology operators and computed tomography nurses, respectively.

“…In addition the heaviness of the lead would cause back strain, and orthopedic injuries in radiation workers who wear the lead aprons for long durations (2)(3)(4)(5) . Therefore production of environmentally-friendly lead-free radiation shields with less weight compared to conventional lead-based shields is a challenging issue in diagnostic radiology and nuclear medicine (6)(7)(8)(9)(10)(11) . Different investigations have been performed to obtain the properties of aprons made by combining elements with different K absorption energies, i.e.…”
