Simultaneous occupational exposure to FM and UHF transmitters.
Occupational exposure caused by large broadcasting transmitters exceeds current reference levels. As it is common for different radio and TV transmitters to share the location, we analysed combined exposure on a 40-m high mast. The frequency modulation (FM) transmitter, located between the 10th and 30th metre, had the power of 25 kW, whereas an ultra-high frequency (UHF) transmitter of 5 kW occ...
متن کاملHearing impairment due to cigarette smoking and simultaneous exposure to occupational noise
Abstract Background : Noise is the most common hazard in the workplace and noise induced hearing loss considered to be the most common occupational disease as well. Cigarette smoking, in some studies, has been known to induce hearing loss. The purpose of this study was to evaluate the effect of contemporary exposure to occupational noise and cigarette smoking on hearing. Methods :...

متن کاملoccupational exposure to blood and body fluids
occupational exposure to blood and body fluids is an important hazard for health care workers, which places them at a high risk for blood-borne infections including hepatitis b virus, hepatitis c virus and human immunodeficiency virus and results in psychological and emotional stresses. several preventive measures have been proposed including pre-exposure ( e.g. , education, use of standard pre...
متن کاملOccupational exposure assessment on an FM mast: electric field and SAR values.
Electric field strengths normally exceed the reference levels for occupational exposure in close vicinity to large frequency modulation (FM) transmitters. Thus, a detailed investigation on compliance with basic restrictions is needed before any administrative protection measures are applied. We prepared a detailed numerical model of a 20-kW FM transmitter on a 32-m mast. An electrically isolate...
