A Novel Design for Production of Efficient Flexible Lead-Free Shields against X-ray Photons in Diagnostic Energy Range
Background: Lead-based radiation shields are widely used in radiology departments to protect both workers and patients from any unnecessary exposure to ionizing radiation. Recently there has been a great deal of concern expressed about the toxicity of lead. Human lead toxicity is well documented. In that light, production of environmentally-friendly lead-free radiation shields with less weight ...
متن کاملBroad-and Narrow-Beam Attenuation of 500- to 1,400- Kilovolt X-Rays in Lead and Concrete
There have been numerous papers over the past 10 years dealing with X-ray protection in the range from 500 to 2,000 kv [1 to 6]. The data from these papers differ somewhat, because the conditions of the experiments were not always the same and therefore cannot be readily correlated. Part of this has been attributed to differences in the high-voltage wave form and inherent filtration for the sev...
متن کاملPreparation and characterization of Epoxy/Lead oxide nano-composite for shield against gamma and X-rays
Polymer nano-composites are a group of materials that represent proper mechanical, chemical, thermal and optical properties due to the presence of certain percentages of a filler in a polymeric matrix. In this study lead oxide nanoparticles were prepared by direct precipitation method. Then the lead oxide-epoxy resin nanocomposite was prepared by mixing (without solvent) with different weight p...
متن کاملRadiation attenuation properties of shields containing micro and Nano WO3 in diagnostic X-ray energy range
Background: It has recently been shown that the particle size of materials used for radiation shielding can affect the magnitude of radiation attenuation. Over the past years, application of nano-structured materials in radiation shielding has attracted attention world-wide. The purpose of this study was to investigate the shielding properties of the lead-free shields containing micro and nano-...
متن کاملRelative thickness of lead, concrete, and steel required for protection against narrow beams of x-rays.
The lead equivalent of X-ray protective barriers are given for both concrete and steel for potentials between 200 an d 1,400 kv . These were determined experimentally u sing a pressure ion ization chamber and an ' _ray tube to which constant potential was applied. Narrow X-ray beam were used. The data obtained are compared with t ho e published by other workers. Data on the relat ive masses ref...
