Objective data from those radiologists who had experienced no back pain before wearing a lead apron (179 radiologists, 26% of those surveyed) were tabulated respondents were grouped according to age, time spent wearing a lead apron, and degree of back pain. They received 236 responses (34% response rate). The questionnaire included both objective items that quantitated apron use and back pain and subjective items that asked, for example, if the respondent believed that lead aprons were responsible for his or her back pain. To investigate this possibility, the authors sent questionnaires to 688 radiologists in various subspecialties whose use of lead aprons varied from none to moderate to extensive. Novelline, R.A.Īnecdotal experience has suggested that back pain in radiologists may result from extensive wearing of lead aprons. Our study does not prove that wearing a lead apron is a significant risk factor for the development of back pain. These and related results were not statistically significant.
Back pain was reported by 52% of those who estimated their lead apron use at greater than or equal to 10 hr per week, the mean response, as opposed to 46% of those who wore lead aprons fewer than 10 hr a week. Answers to subjective questions for all respondents were tabulated.
(Department of Radiology, University of California, San Diego (Unites States))Īnecdotal experience has suggested that back pain in radiologists may result from extensive wearing of lead aprons. The relationship between back pain and lead apron use in radiologists The lead equivalent thickness is defined at the 80 kV level The back side of the body needs less protection and usually is covered by 0.25 mm of lead equivalent. The frontal side of the aprons should be 0.25 mm lead equivalent at working conditions under 100 kV, 0.35 mm for working conditions above 100 kV, and 0.5 mm for heart catheterization and angiography. The lead equivalent thickness of lead aprons worn by the medical staff is defined by many national standards. Heart catheterization and angiography procedures represent the most common exposures of the medical staff. Lead aprons are the major protective item of the medical staff whose work involves x-ray exposure. Narrow Lead Aprons under Medical Fluoroscopy Procedures

Skin exposures measured at the thyroid and at the sternum were reduced with the use of the apron. This study measures the dose reduction obtained with an experimental leaded apron designed for use with panoramic dental x-ray units.
Conventional aprons may produce artifacts when used with panoramic dental x-ray units. The leaded aprons currently available for use during dental radiography do not protect the thyroid gland from radiation. Films produced during the study were free from apron artifacts. Leaded apron for use in panoramic dental radiographyĮnergy Technology Data Exchange (ETDEWEB) The paper discusses the results and the recommendations for use in reactor environment. Based on the results the utility of lead Apron has been discussed in view of ALARA. The protection provided by Apron has been evaluated using personnel dosimeter. Occasionally lead apron of specific design are being used in reactor environment where one-sided radiation fields are encountered. Lead Apron as individual shielding is used primarily in Radiology for protection of personnel against ionizing radiation.
