How much radiation does it take to cause our risk for an observable health effect to increase? Is there a level of radiation that is safe? How is radiation beneficial? The question of an effect occurring because of radiation exposure and the question of whether low‐ level radiation is safe are much‐debated topics. There are many thoughts on the answers to these questions, and suggested answers ...

introduction one of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...

background: human activities such as mining enhance the radioactivity levels above normal background which can lead to an incremental increase in the radiation risk to the population. materials and methods: 20 tailing enriched soil samples collected around maiganga coal mine, gombe, northeast nigeria were assessed for their 226ra, 232th and 40k contents using hpge gamma-ray detector. results: t...

Intestinal microbiota play an important role in our health by immune system modulation, nutrient and xenobiotic metabolism, and sensitivity to radiation-induced injury. The individual susceptibility of humans to radiation is poorly understood and its determination accomplished by large uncertainties in radiation exposure (and radiation risk estimation) which include radiation-quality, dose-rate...

radiography is one of the most valuable diagnostic tools used in comprehensive dental care. although there is no safe level of radiation exposure, the possible risk associated with exposure to radiation, must be elucidated. to date, a variety of assays have been proposed to assess the mutagenic potential of genotoxicants; however, these methods are typically laborious and time consuming. the ai...

Cardiac diagnostic or therapeutic testing is an essential tool for diagnosis and treatment of cardiovascular disease, but it also involves considerable exposure to ionizing radiation. Every exposure produces a corresponding increase in cancer risk, and risks are highest for radiation exposure during infancy and adolescence. Recent studies on chromosomal biomarkers corroborate the current radiop...

BACKGROUND The use of ionizing radiation has led to advances in medical diagnosis and treatment. OBJECTIVES The purpose of this study was to determine the risk of radiation cataractogenesis in the interventionists and staff performing various procedures in different interventional laboratories. PATIENTS AND METHODS This cohort study included 81 interventional cardiology staff. According to ...

Purpose To estimate the benefit-to-radiation risk ratios of mammography alone, breast-specific gamma imaging (BSGI) alone, and mammography plus BSGI in women with dense breasts who were asymptomatic and examined in the 2015 study by Rhodes et al. Materials and Methods This study uses previously published breast cancer detection rates and estimates of radiation dose and radiation risk and is, th...

ntroduction: The purpose of this study was to measure the radioactivity in the agricultural soil of south-east of Shazand Refinery Complex to determine both reliable baseline data on the radiation level and the radiation dose exposure to the farmers and inhabitants of the studied area. Material and Methods: This study was conducted on 21 soil...
