OSTI ID:4325092

The X-ray Exposure Study conducted by the U. S. Public Health Service was designed to produce estimates of the x-ray experience of the U. S. population in 1970. A similar study was performed in 1964, and some of those results are reproduced in this report. In addition to the principal findings, this report contains a description of the background, objectives, design, methods, and procedures used in the study to produce estimates of exposure for a variety of personal and demographic characteristics of the U. S. population. In addition, the study design provided a basis for estimating specific organ and genetic dose for x-ray exposure when used with models developed through research at several universities. X-ray visit data were obtained from a representative sample of the U. S. population through a supplementary questionnaire included in the Household Interview Survey, a continuing program of the National Center for Health Statistics. A sample of approximately 67,000 people in 22,000 households provided this information during the period April to September 1970. The study showed that: the estimated mean exposure per film for posterior-anterior and anteriorposterior views of the abdomen increased from an estimated 480 mR in 1964 to 620 mR in 1970; the estimated mean exposure per film for radiographic PA chest examinations remained about the same, approximately 28 milliroentgens in 1964 and 27 in 1970; and there was a 20-percent decrease in the mean exposure per dental film from an estimated 1,140 mR in 1964 to 910 mR in 1970.
