Introduction: Interventional angiography procedures are increasingly used today. These techniques require a long time of standing near the patient and x-ray tube which lead to increase the radiation-dose of the staff and interventionists. This may also, in turn, lead to the occurrence of radiation deterministic effects. Since a large number of interventional radiology were perf...

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

Background: Exposure conditions in CT examinations are quite different from conventional Xray. In CT examination higher dose is given to patient in comparison with the dose in other diagnostic examinations. In order to calculate organ effective dose in chest CT, Monte Carlo simulation has been used in this study. Materials and Methods: The Impact survey data were used to determine the ...

Background: Breast cancer is a common disease in radiation oncology. We evaluated the radiation dose received by breast cancer patients, an often-neglected concern. Materials and Methods: The total effective radiation dose in 101 breast cancer patients was calculated by summing the effective doses of individual diagnostic imaging tests from the first hospital visit to the initiation of radiothe...

The paradigm of the response of a biological organism to exposure to stressor agents is hormetic dose response, in which high doses of a stressor are toxic or harmful but low doses are beneficial. The exploitation of this biological characteristic could enable the efficient use of plants in the fields of phytoremediation and agriculture.

PURPOSE We aimed to determine the effective dose given to patients during neuroradiological C-arm computed tomography (CT) procedures. MATERIALS AND METHODS Measurements were performed on 48 patients using a dose-area product (DAP) meter. A PC-based Monte Carlo program (PCXMC, STUK, Helsinki, Finland) was used to calculate the effective dose from the DAP values of each patient. Organ doses we...

background: the radiation doses resulting from diagnostic x-ray examinations are routinely measured in terms of entrance surface dose (esd) and effective dose (ed). in this study, for the purpose of radiation protection, the radiation doses received from digital chest x-ray examination were evaluated in terms of esd and ed. material and methods: the ed was calculated by using the mcnp monte car...
