Exposition des professionnels médicaux aux rayonnements ionisants et risque de cancer
Les expositions aux rayonnements ionisants (RI) à forte dose ont été reconnues comme facteur de risque de cancers (1). Les effets à long terme des rayonnements ionisants à faibles et moyennes doses restent débattus. De nombreuses études épidémiologiques portant sur le suivi des survivants des bombardements d’Hiroshima et de Nagasaki et sur le suivi des travailleurs exposés aux RI ont montré des augmentations de risque de cancer et de pathologies cardiovasculaires (2). Les professionnels de santé, notamment...
New models for prediction of micronuclei formation in nuclear medicine department workers
Background : Ionizing radiation causes detrimental health effects such as cancer and genetic damage. The study aim was to determine predictors for micronuclei (MN) occurrence and frequency in peripheral blood lymphocytes of health workers professionally exposed to radiation. Methods : Health workers, age matched, selected for the study on regular check-ups, were divided according to the radiation exposure. The exposed group involved nuclear medicine department employees (54) and the control group comprised workers from other departments (36). Data about workers characteristics and habits, received...
Ionising radiation and risk of death from leukaemia and lymphoma in radiation-monitored workers
An international cohort study Background: There is much uncertainty about the risks of leukaemia and lymphoma after repeated or protracted lowdose radiation exposure typical of occupational, environmental, and diagnostic medical settings. We quantified associations between protracted low-dose radiation exposures and leukaemia, lymphoma, and multiple myeloma mortality among radiation-monitored adults employed in France, the UK, and the USA. Methods: We assembled a cohort of 308 297 radiation-monitored workers employed for at least 1 year by the Atomic Energy Commission, AREVA Nuclear Cycle, or the...
The Risk of Radiation Exposure To Assisting Staff in Urological Procedures
A Literature Review Fluoroscopy is an integral part of urology and is used for various procedures, such as extra-corporeal shock wave lithotripsy, percutaneous nephrolithotomy, uretero-renoscopy, and ureteral stenting. This technique exposes the urologist and assistants to radiation, which is known to have deleterious effects. Although there have been studies that determine the amount of exposure and the risks to the operating urologist, the risk to the assisting staff remains largely undetermined. A literature review was conducted to determine the risk of radiation exposure during urological procedures...
Radiation Sources in Natural Gas Well Activities
More attention and monitoring of occupational radiation exposure in the natural gas industry are warranted . The boom in the natural gas industry across the nation, made possible by recent advances in hydraulic fracturing ("fracking") methodology, has resulted in increased concern for public and environmental safety. This, in turn, has resulted in a series of recommendations for minimizing the risk to the public and the environment (Secretary of Energy, 2011). The natural gas industry has responded to environmental concerns by cleaning and recycling frack water, which can take the form...
