Natural environmental gamma radiation exposure and prevalence of breast cancer in Poços de Caldas, MG, Brazil
Background: Environmental ionizing radiation has been associated with increased cancer risk by several studies. The Brazilian city of Poços de Caldas, MG, seats on a huge deposit of uranium, which was until recently mined. We performed a retrospective analysis of 310 cases of patients with breast cancer, who were exposed for at least ten years to different levels of ion...
متن کاملUltraviolet radiation exposure, vitamin D, and cancer.
This paper reviews briefly the evidence for an association between various measures of UV radiation (UVR) exposure and the development of cancer. Issues such as data quality, study design, measurement variation, comparability of studies, and quantification of UV exposure in relation to skin cancer are discussed. A range of exposure, based on skin type, might be appropriate: from 5 min a day thr...
متن کاملRadiation exposure and thyroid cancer: a review.
The association between radiation exposure and the occurrence of thyroid cancer has been well documented, and the two main risk factors for the development of a thyroid cancer are the radiation dose delivered to the thyroid gland and the age at exposure. The risk increases after exposure to a mean dose of more than 0.05-0.1 Gy (50-100mGy). The risk is more important during childhood and decreas...
متن کاملEvaluation of Radiation Exposure Pattern and Radiation Absorbed Dose Resulting from Occupational Exposure of Anesthesiologists to Ionizing Radiation
Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...
متن کاملRisk of Cancer in Occupational Exposure to Radar Radiation: A Systematic Review
Background and aim: Microwave radiations are one of the most environmental workplace factors that exposed too many workers. In microwave spectrum, radar frequency with 1-300 GHz range have varied applications such as satellite, communications, military, Network, navigation, air-traffic Control, navigation, marine and weather. Uncontrolled occupational exposure to radar radiation caused to vari...
