Purpose: To ensure radiation safety of medical staff personal protective equipment (PPE). Material and methods: In order to not make assumptions of possible protective materials optical distortion, estimated the dependence of light transmission in the wavelength range 330–660 nm leaded glass brands of TF-1 and TF-5, as well as the intensity of glow glasses when exposed to light and X-rays. Results: We trace the degree of browning and the nature of the recovery of transparency of glass after irradiation. To determine the optimum thickness of lead glass for eyewear experimentally evaluated attenuation of X-rays with energy efficiency 30 and 80 keV. Lead equivalent values for lead glass, was determined so for Eeff ~ 20 keV at a multiplicity of weakening k = 10 lead glass brand TF-5 thickness 2.0 mm equivalent 0.8 mm Pb, etc. For the possible use of other additives in the window shows the curves of the attenuation of photon radiation radionuclide 241Am (20–60 keV) filters from 9Be, 26Al, 56Fe, 64Cu, 99Mo, 112Cd, 184W, 207Pb Conclusion: Possible introduction of new dose limits for the lens of the eye can be successful only in case of both existing and newly developed PPE. To reduce the impact of domestic lead glass radiation can be used for staff in the form of screens and glasses.
