introduction radiotherapy is regarded as the first treatment of choice for nasopharyngeal carcinoma. despite the advantages of radiotherapy, patients may suffer from a wide range of side-effects due to the presence of many sensitive normal tissues in these regions. if the absorbed dose exceeds the tolerance level in parotid glands and the spinal cord, myelopathy, lhermitte's sign and xeros...

Abstract— A technique for studying the spatial structure of hybrid X-pinch plasma objects in X-ray range is described, and main experimental results are presented. The spectral characteristics sources have been measured. investigations carried out using thermoluminescent detectors based on lithium fluorides LiF(Mg, Ti).

We evaluated photoluminescence, scintillation and thermoluminescent characteristics of BaCaBO3F doped with various amounts Tb to fabricate new phosphors for radiation measurements. Sharp peaks centered at 491, 542 589 nm originating from the electronic 4f→4f transitions Tb3+ appeared in photoluminescence spectra X-ray induced spectra. These derived decay times under ultraviolet light were appro...

OBJECTIVE The purpose of this paper is to show the effectiveness of a new radiation protection method designed to decrease the amount of scatter radiation received by practitioners performing procedures under fluoroscopic guidance. MATERIALS AND METHODS A sterile, disposable, lead-free surgical drape containing radiation protection material composed primarily of bismuth was evaluated for effe...
