PURPOSE The aim of this study was to investigate the potential dose reduction in the uterus as a result of lead apron protection during thoracic CT scans. Moreover, the distribution of the radiation dose in the uterus was determined in order to obtain information about the ratio of internally and externally scattered radiation. MATERIALS AND METHODS The uterus doses during thoracic CT were de...

Pressure garments are the main method of treatment and prophylaxis for hypertrophic burn scars. The pressure they exert on the scarred skin prevents contractures forming, reduces the itchiness and pruritus associated with active hypertrophic scars, and is believed, by many, to hasten normalization of the scar tissue. The pressure exerted is believed to be critical to treatment success and can b...

UNLABELLED Because of the penetrating ability of the radiation used in nuclear medicine, metallic lead is widely used as radiation shielding. However, this shielding may present an insidious health hazard because of the dust that is readily removed from the surfaces of lead objects. The lead dust may become airborne, contaminate floors and other nearby surfaces, and be inadvertently inhaled or ...

While mechanical cloth simulation systems are widely used for creating draped garments on virtual characters, the animation of virtual garments raise challenges on its own. The perception of garment beauty is first related to the dynamic accuracy of the cloth simulation model, which has to reproduce precisely the dissipative behaviors of the material, such as viscosity and plasticity, rendering...

Long term exposure to very high levels of radiations from medical diagnostic centres, industries, nuclear research establishments and weapon development have resulted in health effects such as cancer acute radiation syndrome, hence the need for proper shielding. This paper investigated Epoxy-Lead (II) Oxide (PbO) composite The composites were prepared by dispersion microsized PbO particles into...

In the present work, transmission factors of γ-rays are determined in bi-layered shields composed lead and steel, through a methodology three distinct parts. The buildup calculation was performed using published by Broder 1962 [1]. A computational simulation used spherical model, total concentric spheres were simulated, with source center spheres. first sphere represents shield its radius is re...
