an extensive study was undertaken to investigate on the overall film badge service performance with which occupational radiation, exposures are reported in iran, the study involved the analysis of film badges exposed to x-and gamma rays and beta particles. for test exposures, x-rays between 60 and 140 kvpco-60 gamma radiation and sr-90 beta particles were used. the actual delivered dose equival...
background: the aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at bahawalpur institute of nuclear medicine and oncology department. materials and methods: annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to radiation dosimetry laboratory (rdl), pakistan institute of nuc...
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 and objective: professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....
The continuing increase in the worldwide use of X-ray imaging has implications for radiation protection of medical staff. Much of the increased usage could be viewed as simply a workload issue with no particular new challenges. However, advances in technology and developments in techniques have seen an increase in the number of X-ray procedures in which medical personnel need to maintain close ...
Introduction: Welding is considered to be one of the main sources of occupational exposure to non ionizing radiations. The present study was conducted to examine the rate of occupational exposure to non-ionizing radiation in common welding processes. Materials and Methods: In the present descriptive analytical study, occupational exposure to different types of non-ionizing radiations in...
Background and Objective: Professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. Occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. Biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....
BACKGROUND Studies suggest that ambient sunlight plays an important role in the pathogenesis of non-melanoma skin cancers (NMSC). However, there is ongoing controversy regarding the relevance of occupational exposure to natural and artificial ultraviolet radiation (UV) radiation. OBJECTIVES We investigated potential associations between natural and artificial UV radiation exposure at work wit...
Ionizing radiation is a well-known carcinogen, and is listed as one carcinogenic agent of occupational cancer. Given the increase in the number of workers exposed to radiation, as well as the increase in concern regarding occupational cancer, the number of radiation-related occupational cancer claims is expected to increase. Unlike exposure assessment of other carcinogenic agents in the workpla...
