Long-term exposure to low doses of ionizing radiation may affect cells and tissues and result in various adverse health effects. The purpose of this study was to investigate whether chromosome aberrations and haematological alterations could be used as biomarkers of possible radiation injury in workers exposed to ionizing radiation. Groups totalling 323 medical professionals handling X-ray equi...

exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. measurement of the annual radiation dose hazards was performed using a halogen-quenched gm tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. the gm tube was plac...

Although high dose ionizing radiation (>100 mSv) harms humans, particularly (but not exclusively) concerning cancer, the effect of lower radiation doses is less clear. Low dose radiation exposure is of societal importance in relation to screening tests for cancer and occupational radiation exposure, as two examples. Inflammatory bowel disease (IBD) patients and cancer survivors undergo multiple...

Journal of American Physicians and Surgeons Volume 21 Number 3 Fall 2016 Diagnostic imaging with low-dose ionizing radiation helps physicians save lives and assist in prolonging good health. Numerous publications1-5 based on clinical, epidemiological, and ecological studies have claimed increased cancer risk associated with low radiation doses such as received from diagnostic imaging and other ...

The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to radiation at dose 15Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

Introduction: Exposure to ionizing radiation can trigger adverse biological effects on healthy tissues, such as causing hematological toxicity and potential injury to different organs. Ionizing radiation has sufficient energy to liberate electrons from atoms leaving them with unpaired electrons; hence ionizing them and producing free radicals. In the current study, the...

BACKGROUND Radiological practices are the first anthropic sources of ionizing radiation exposure of the population. However, a review of recent publications underlines inadequate doctors' knowledge about doses imparted in medical practices and about patient protection that might explain unnecessary radiological prescriptions. We investigated the knowledge of the physicians of Pavia District (It...

For the last 40 years the use of Computed Tomography “CT” in Medical Imaging has been increasing dramatically. Yearly CT scans done in US have risen from less than 3 million in 1980 to currently being more than 80 million a year. Last year in Australia, Medicare has paid for 3 million CT examinations that does not include Hospital inpatients, private insurance and workers compensation and Motor...

BACKGROUND ionizing radiation on the lens of the eye can produce a progressive cataract. Small cumulative doses, over a long time period, can produce adverse effects on the professional capabilities of health workers in the ionizing radiation zone. OBJECTIVES The aim of this study was to ascertain whether occupational exposure to low levels of ionizing radiation can cause an increase in preva...
