The National Dose Registry (NDR) of Canada is a unique resource for a direct estimation of the potential health risks associated with low doses of ionizing radiation. This is the largest national occupational radiation exposure database, comprising records for about 600,000 nuclear, industrial, medical and dental workers. An analysis of the NDR data based on a cohort of about 200,000 workers fi...

Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...

We have assembled this mini-monograph on adult lead exposure to provide guidance to clinicians and public health professionals, to summarize recent thinking on lead biomarkers and their relevance to epidemiologic research, and to review two key lead-related outcomes, namely, cardiovascular and cognitive. The lead standards of the U.S. Occupational Safety and Health Administration are woefully o...

BACKGROUND Intramedullary nailing under fluoroscopic guidance is a common operation. We studied the intraoperative radiation dose received by both the patient and the personnel. PATIENTS AND METHODS 25 intramedullary nailing procedures of the tibia were studied. All patients suffered from tibial fractures and were treated using the Grosse-Kempf intramedullary nail, with free-hand technique fo...

Workers at U.S. facilities that use radioactive materials are subjected to a small occupational health risk. The Nuclear Regulatory Commission sets standards to ensure their safety. The agency limits worker doses to no more than five rem (5,000 millirems) per year and requires that occupational doses be kept “as low as reasonably achievable.” Radiation workers are individually monitored to reco...

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...

Occupational asthma after exposure to salbutamol in the pharmaceutical industry has not been previously reported. The occurrence of occupational asthma is described in two pharmaceutical process workers who were likely to have inhaled doses appreciably in excess of the therapeutic dose range. The findings do not lead to an unequivocal conclusion on the mechanism of the asthma but it was probabl...

  Introduction: Because radiology technologists are exposed to protracted low-dose ionizing radiation and considering the possible effects of low-dose radiation on blood factors, we aimed to investigate the effects of occupational exposure on blood factors of radiographers working in radiology departments of Khuzestan Province, Iran.   Materials and Methods: This case-control study was conducte...

BACKGROUND Recent years have seen increased levels of production and consumption of seafood, leading to more frequent reporting of allergic reactions in occupational and domestic settings. This review focuses on occupational allergy in the fishing and seafood processing industry. REVIEW Workers involved in either manual or automated processing of crabs, prawns, mussels, fish, and fishmeal pro...
