AIMS To study the risk of childhood cancer in relation to parental occupation and related exposures. METHODS Self reported occupational data from mothers and fathers of 3838 children with cancer and 7629 control children were analysed. Odds ratios were calculated for 31 "occupational groups" by parent, diagnostic group (leukaemia, acute lymphoblastic leukaemia (ALL), central nervous system tu...

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...

The countries of central Europe, including Poland, the Czech Republic, Slovakia, Hungary, Romania, and Bulgaria, suffer from environmental and occupational health problems created during the political system in place until the late 1980s. This situation is reflected by data on workplace exposure to hazardous agents. Such data have been systematically collected in Skovakia and the Czech Republic...

Three areas of activity in the field of low-level radiation epidemiology have been reviewed. They concern the questions of cancer risk related to antenatal X-ray exposure, occupational radiation exposure, and residence in areas of real or supposed increased levels of radiation. Despite the a priori unlikelihood of useful information developing from studies in any of these areas, such investigat...

background :asthma is the most common respiratory disease with an increasing prevalence. on the other hand, obesity is also a challenging disease compromising health in human communities. this study sought to assess the correlation of asthma and body mass index (bmi) in occupational setting.   methods : this study was conducted in a cable manufacturing company in 2012. a total of 551 workers fr...

introduction the purpose of this study was to evaluate personal shields in radiation departments of hospitals affiliated to mashhad university of medical sciences. materials and methods first, the information related to 109 personal shields was recorded and evaluated by imaging equipment. afterwards, the equivalent lead thickness (elt) of 62 personal shields was assessed, using dosimeter and st...

health care workers (hcw) are at high risk of occupational exposure from blood-borne pathogens. the most important pathogens that can be transmitted to hcw are hiv with prevalence of 2.24 per 100000, hbv with prevalence of 2.3%, and hcv with prevalence of 0.2% in iran. most of this occupational transmission can be prevented through standard precautions reducing exposure. these precautions, howe...

The Fukushima Daiichi Nuclear Power Plant (NPP) 1 was severely damaged from the chain reaction of the Great East Japan Earthquake and Tsunami on 11 March 2011, and the consequent meltdown and hydrogen gas explosions. This resulted in the worst nuclear accident since the Chernobyl accident of 1986. Just as in the case of Chernobyl, emergency workers were recruited to conduct a wide range of task...

AIMS Interventional cardiologists who work in cardiac catheterisation laboratories are exposed to low doses of ionising radiation that could pose a health hazard. DNA damage is considered to be the main initiating event by which radiation damage to cells results in development of cancer. METHODS AND RESULTS We report on four interventional cardiologists, all with brain malignancies in the lef...
