Dentists, as well as other dental personnel are constantly exposed to a number of specific occupational hazards. These cause the appearance of various ailments, specific to the profession, which develop and intensify with years. In many cases they result in diseases and disease complexes, some of which are regarded as occupational illnesses. Relying on relevant literature, the present paper dis...

Health hazards are of great concern to cellular phone users. One important measure of the effect of electromagnetic radiation into human body is the specific absorption rate (SAR). If the human body is exposed to electromagnetic radiation, the amount of power absorbed by its tissues per mass volume should be limited and not to exceed a maximum SAR value. The cellular phone radiated through its ...

Background: Measurement of the radiation dose distribution is important in assessing the health risk a population and serve as reference in documenting changes to environmental radioactivity in soil due to man-made activities. Materials and Methods: The activity concentration of 238U, 232Th and 40K in soil samples obtained from different locations in Ajaokuta Local Government area was measured ...

Knowledge and concern degree about work-related radiation hazards remained unknown among orthopedic surgeons. The aim of the cross-sectional study is to investigate whether the knowledge degree of work-related radiation is associated with psychological distress among orthopedic surgeons. This cross-sectional study sent electronic questionnaire via WeChat to orthopedic surgeons nationwide. Conce...

The effect of exposing rats to amplitude modulated radiofrequency radiation (112 MHz modulated to 16 Hz) during development and growth has been examined. Wistar rats (35 days old) when exposed at above frequency at the power level 1.0 mW/cm2 (SAR, 0.75 W/kg) for 35 days showed enhanced ornithine decarboxylase activity and Ca2+ efflux in brain indicating potential health hazards due to exposure.

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...

background: the potential hazards of exposure to radiation from radon have been of great concern worldwide, as it is associated with an increased risk of lung cancer. radon (222rn) and its progeny are the main sources of radioactivity in the environment. the half-life of 222rn (3.82 days) is long enough for it to diffuse into and build up in homes. 220rn or thoron from the 232th series, and 219...

vesicoureteral reflux (vur) is a relatively common and important entity in children. vur can expose patient to risk of pyelonephritis, permanent renal damage or scar. vur itself has no deleterious effect on kidney parenchyma until the development of infection or increased intravesical pressure.   the diagnosis of vur could lead to appropriate therapy and prevention of long term complications. t...

A clinical case of the development rapidly progressive systemic sclerosis after repeated coronavirus infection is described. The contribution occupational hazards, oncological process and radiation therapy to pathogenesis this disease discussed. Hydropericardium was a feature picture, as well rare immunological markers late onset sclerosis.
