“…The more recent demand for non-Pb radiation protection garments to avoid hazardous material disposal issues has resulted in the production of materials that incorporate one or more less toxic metal powders into polymer layers. [12][13][14][15][16][17][18] Many radiation protection garments tend to be uncomfortably heavy if worn for long periods. A moderate reduction in weight can result from using appropriate non-Pb materials, providing a second major motivation for investigating non-Pb materials for radiation protection.…”

New non-Pb compound materials, particularly single layers or bilayers incorporating Bi(2)O(3), can reduce the weight of radiation protection materials while providing equivalent or better protection compared to Pb-based materials. Attenuation measurements in geometries that exclude the contribution from fluorescence substantially underestimate the quantity of transmitted radiation. A new Bi(2)O(3)-loaded hand cream demonstrated a novel and effective approach for hand protection. Standard testing protocols for radiation protection materials used by IR physicians specify a wider kVp range than is necessary. A more realistic range would acknowledge the lower kVp resulting from scatter and allow IR physicians to confidently utilize lighter-weight materials while still receiving adequate protection. Standards protocols incorporating the adjustments described in this work would maintain the safety of IR personnel and lessen the physical repercussions of long hours wearing unnecessarily heavy radiation protection garments.

“…To resolve this problem, lighter aprons, made of composite materials, have been developed successfully [4–6]. These composite materials include several heavy metals such as copper, yttrium, tin, antimony, barium, tungsten, and lead [7–9]. However, manufacturers have not adequately released information about these composites [9–11].…”

“…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]. 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.

Background: Dental radiology had helpful assistant in the diagnosis and treatment of oral diseases. Dentists in their practice have to access benefits of dental oral radiographs against its hazards. They must be aware of new radiation protection techniques and radiation dosage which daily receive. Present study was performed for radiation protection awareness in dentists of Yazd city and their knowledge about recent lowering radiation techniques. Materials & Methods: Present cross sectional study was performed on 102 medical dentists of Yazd city. Our study samples were participated in one Continues Medical Educations (CME) session. Knowledge assessment of study medical dentists was gathered with questionnaire which was given to study participants during CME session. Results: Eighty nine percent of dentists had poor and 11% had moderate awareness about radiation protection techniques. There was no significant difference between mean of knowledge scores among study participants according their age groups, job experiences and genders. Conclusion: The knowledge of dentists about radiation protection techniques was very poor and they should implement recent and appropriate radiation protection techniques and guidelines.
