Issues in medical exposures

Journal of Radiological Protection, 2009
Medical exposures account, on average, for some 14% of the background ionising radiation exposure in the UK and form the great majority of the non-natural component. In the United States of America, medical exposures comprised over 50% of the total in 2006.

Medical X-Ray Exposure

American Industrial Hygiene Association Journal, 1963
Abstract Upon man's natural background exposure to ionizing radiation, modern uses of radioactive materials and radiation producing machines have superimposed further exposures. Added exposures through use of medical x-ray procedures can seriously exceed the tolerance levels. The severity of these hazards in the U.S.A.

Medical UV Exposures and HIV Activation

Photochemistry and Photobiology, 1996
AbstractThis paper presents the first attempt to evaluate the potential of clinical UV exposures to induce the human immunodeficiency (HIV) promoter and, thus, to upregulate HIV growth in those skin cells that are directly affected by the exposure. Using the data for HIV promoter activationin vitro, we computed UVB and psoralen plus UVA (PUVA) doses ...

Exposure of Medical Students to Body Fluids

Journal of American College Health, 1999
Three hundred forty-two students at 3 Florida medical schools were surveyed concerning occupational exposures to blood and body fluids during their 3rd-year clerkship. The 16-item questionnaire was anonymously returned by 150 students, and differences among groups were assessed at p < .05.

Medical surveillance programme for diisocyanate exposure

Occupational and Environmental Medicine, 2010
ObjectivesSurveillance programmes for occupational asthma should reduce the severity of asthma both at the time of diagnosis and after removal from exposure as well as costs related to functional impairment. The aim of this study was to compare the severity and cost of diisocyanate-induced occupational asthma in workers participating in a surveillance ...

MEDICAL CONSIDERATIONS OF EXPOSURE TO MICROWAVES (RADAR)

Journal of the American Medical Association, 1958
Apprehension over the possibility of injury to man by microwaves is based largely on the fact that sufficiently intense and prolonged radiation of this frequency has caused severe injuries to experimental animals. Several hundred workers who have been occupied about radar installations or have been exposed to radar beams have therefore been observed in

Non-medical exposures--ethical concerns

Radiation Protection Dosimetry, 2009
The scope of the Medical Exposure Directive (MED), 97/43/Euratom (Council Directive 97/43/EURATOM, on the health protection of individuals against the dangers of ionising radiation in relation to medical exposures. OJ L 180 of 09.07.1997), is such that it includes not only those exposures which are part of the normal diagnosis and treatment of patients

Medical Exposure to Radiation and Thyroid Cancer

Clinical Oncology, 2011
In 2008, the worldwide estimated age-standardised incidence rates for thyroid cancer incidence were 4.7 and 1.5 per 100,000 women and men, respectively. Thyroid cancer's overall contribution to the worldwide cancer burden is relatively small, but incidence rates have increased over the last three decades throughout the world.
