background: dose assessment using proper dosimeters is especially important in radiation protection optimization and imaging justification in diagnostic radiology. objective: the aim of this study is to obtain the entrance skin dose (esd) of patients undergoing lumbar spine imaging using two thermoluminescence dosimeters tld-100 (lif: mg, ti) and gr-200 (lif: mg, cu, p) and also to obtain the a...

background: intraoral radiographies are the most frequent x-ray examinations in humans. according to international commission on radiation protection (icrp) recommendations, the selection of a diagnostic reference level (drl) should be specific to a country or region. critica l organs such as thyroid gland are exposed to x-rays in intraoral radiography and these exposures should be kept as low ...

introduction radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. therefore, entrance skin dose (esd), body organ dose (bod), and effective dose (ed) from adult patients undergoing routine thorax posterior-anterior (pa) and thorax right lateral (rlat) were estimated in uni...

background: one of the means of assessing dose to patients from computed tomography (ct) procedure is through the determination of the skin entrance dose (esd) with the appreciation of the concern that ocular exposure effects from ct scan includes possible induction of cancer and cataract. due to the relatively more recent introduction of ct scans, little work has been done in this area in the ...

background: there is not any report on the radiation doses received by patients in diagnostic radiology sections in hospitals under control of chaharmahal and bakhtiari medical sciences university, in the south west of iran. objectives: the aim of this study is measurement of entrance surface doses (esd) for the most routine types of x-ray procedures in radiology centers as part of ongoing dose...

Children with complex congenital heart diseases often require repeated cardiac catheterization; however, children are more radiosensitive than adults. Therefore, radiation-induced carcinogenesis is an important consideration for children who undergo those procedures. We measured entrance skin doses (ESDs) using radio-photoluminescence dosimeter (RPLD) chips during cardiac catheterization for 15...
