background : exposure to formaldehyde (fa) causes irritative effects and induces nasopharyngeal cancer; the interna­tional agency for research on cancer (iarc, lyon) classified fa as carcinogenic to humans, group 1. many studies have been published so far concerning the occupational exposure of industrial workers, embalmers, pathologists and anatomists to fa but very few data regarding medical ...

Medical diagnostic X-ray workers are one occupational group that expose to the long-term low-dose external radiation over their working lifetime, and they may under risk of different cancers. This study aims to determine the relationship between the occupational X-ray radiation exposure and cancer risk among these workers in Jiangsu, China. We conducted Nested case-control study to investigate ...

occupational asthma is defined as “a disease of variable airflow limitations and/or airway hyper-responsiveness due to causes and conditions attributable to a particular occupational environment and not stimuli that are being encountered outside the workplace.” an analysis of general population-based studies published up to 2007 showed that 17.6% of all adultonset asthma is due to workplace exp...

alzheimer’s disease, the most common type of dementia and a progressive neurode-generative disease, occurs when the nerve cells in the brain die. although there are medications that can help delay the development of alzheimer’s disease, there is cur-rently no cure for this disease. exposure to ionizing and non-ionizing radiation may cause adverse health effects such as cancer. looking at the ot...

BACKGROUND Radiation, which is used extensively to diagnose and treat human diseases, poses an occupational health risk for the concerned health workers. Personal dosimetry is an important tool to monitor occupational radiation exposures. OBJECTIVE This study was conducted to reveal and to describe the situation of occupational radiation exposure monitoring among staffs in different health ca...

Increased use of intraoperative fluoroscopy exposes the surgeon to significant amounts of radiation. The average yearly exposure of the public to ionizing radiation is 360 millirems (mrem), of which 300 mrem is from background radiation and 60 mrem from diagnostic radiographs. A chest radiograph exposes the patient to approximately 25 mrem and a hip radiograph to 500 mrem. A regular C-arm expos...

This instructional material is intended to provide the user with the best available information concerning what is currently known about the health risks from exposure to ionizing radiation. A question and answer format has been used. The questions were developed by the NRC staff in consultation with workers, union representatives, and licensee representatives experienced in radiation protectio...

The report presents results on finding appropriate biomarkers applicable in molecular epidemiological surveys of occupationally exposed individuals and/or population to study low dose effects. Blood samples were collected from the “strict regimen” area personnel (exposed) and the administrative staff (controls) of NPP-Kozlodui. Two levels of evaluation were used: molecular spontaneous and induc...
