background : farmers and welders who work in open spaces and are exposed to direct sunlight are often exposed to sunlight radiation o n the neck and head . thus, they may be afflicted with various types of skin cancer . the aim of the present study was to investigate the amount of uv exposure in welders working in shahrud city , iran .   materials and method s : this cross-sectional , descripti...

Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...

background: astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. the application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. the aim of the present study was to investigate ...

patients and methods we evaluated radiation exposure from initial and downstream testing in a prospectively collected, matched cohort evaluated for cp in the emergency department (ed) with either ccta compared with usual care over a median follow-up of 19.6 months. effective radiation dose was calculated using published conversion factors. results prospective, ecg-triggered acquisition using a ...

background: the rapidly increasing use of mobile phones has led to public concerns about possible health effects of these popular communication devices. this study is an attempt to investigate the effects of radiofrequency (rf) radiation produced by gsm mobile phones on the insulin release in rats. methods: forty two female adult sprague dawley rats were randomly divided into 4 groups. group1 w...

introduction: occupational exposure to ionizing radiation due to medical activities (both diagnostic and therapeutic procedures) has increased sharply in recent years. among the occupationally exposed workers in these fields, those most affected by this increased exposure to ionizing radiation are nuclear medicine workers. in this study, annual average effective dose, annual collective effectiv...

Background: The aim of this study was to calculate the radiation amount exposed during percutaneous nephrolithototomy (PCNL) and to make the urologists and other staff sensitive about the radiation risk they were exposed to. Materials and Methods: We measured the radiation exposure during 114 cases of PCNL performed. Thermoluminescent dosimeters (TLD) were placed between the operation table and...
