“…One lead, and two lead-free aprons were tested for x-ray absorption ability in both the primary and scattered radiation fields. The method for the measurements performed in this study (with and without the aprons) is based on methods described in previous studies 5, [14][15][16] .…”

“…The difference ranged from -9.5% to -13.3%, for selected tube voltages 60 kVp and 113 kVp, respectively. Furthermore, the lead equivalent thickness of the lead-free aprons in the direct radiation beam was also determined, in order verify whether they fulfilled the lead-equivalent value given by the manufacturer 3,16 . The results showed that the lead-free aprons fulfilled the equivalent lead thickness of 0.35 mm specified by the manufacturer.…”

Aim: To compare the absorption ability of two lead-free aprons with a lead apron. Method: Measure and compare the absorption ability of 3 aprons; OpaqFu bilayer apron containing bismuth and antimony, NoLead one layer apron containing antimony, and a lead apron. The measurements were repeated with and without each of the aprons present in both primary and scattered beams. The selected tube voltages were between 60 and 113 kVp with constant mAs, a fixed field size and fixed source to object distance. Results: No significant difference in absorption ability of the two lead-free aprons compared to the lead apron were observed when the dose was measured in the primary beam. When measurements were performed in the scatter radiation field, the absorption ability of the OpaqFu apron was 1.3 times higher than NoLead apron and nearly equal to the absorption ability of the lead apron. An increase in the difference between the OpaqFu and NoLead aprons was observed for the tube energies higher than 100 kVp in favor of OpaqFu apron. Conclusion: It is safe to use the lead free aprons that were tested in this study in a clinical environment for the tube energy range of 60-113 kVp.

“…To determine whether the shielding sheet is effective, a lead equivalent test method is utilized, (17,18) specified in the European Industrial Standard for X-ray protective supplies was employed (IEC 61331-3:2014). (19) Additionally, the GE Healthcare DefinirionTM 6000 X-ray generator's effective energy was measured (USA).…”

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.

“…Furthermore, lightweight gowns are recently made from alternative sorbents (with lower atomic numbers) in combination with lead, and their manufacturers claim that attenuation characteristics are equivalent to lead. The “lead-equivalent” parameter is not clear since the properties of photon attenuation are significantly different during the energy spectrum for all materials, such as lead; the largest changes are in the diagnostic imaging range (70-120 kVp) [ 17 , 18 ]. Most radiologists, who work with interventional methods, do not know that weight reduction for the protective gown can only be achieved in the range of kVp, and the photon energy and the duration of wearing is a potential trade-off between weight and radiation protection [ 9 , 18 ].…”

Background: Radiation protection plays a key role in medicine, due to the considerable usage of radiation in diagnosis and treatment. The protection against radiation exposure with inappropriate equipment is concerning. Objective: The current study aimed to investigate the efficiency and quality of the radiation protection gowns with multi-layered nanoparticles compositions of Bismuth, Tungsten, Barium, and Copper, and light non-lead commercial gowns in angiography departments for approval of the manufacturers’ declarations and improve the quality of gowns. Material and Methods: In this case study, physicians, physician assistants, radiology technologists, and nurses were asked to wear two commercial and proposed gowns in the angiography departments. Dosimetry of personnel was conducted using a Thermoluminescent Dosimeter (TLD) (GR-200), and the radiation dose received by personnel was compared in both cases. The participants were asked to fill out a questionnaire about the quality and comfort of two radiation protection gowns. Results: However, both gowns provide the necessary radiation protection; the multi-layer proposed gown has better radiation protection than the commercial sample (2 to 14 percent reduction in effective dose). The proposed gown has higher flexibility and efficiency than the commercial sample due to the use of nanoparticles and multi-layers (2.3 percent increase in personnel satisfaction according to the questionnaires). Conclusion: However, the multi-layer gown containing nanoparticles of Bismuth, Tungsten, Barium, and Copper has no significant difference from the non-lead commercial sample in terms of radiation protection, it has higher flexibility and comfort with more satisfaction for the personnel.
