X-ray studies of the thoracic region amount to 30% of all diagnostic x- ray studies and hence may cortribute to genetic effects of radiation injury. Quantitative evaluation of radiation injury depends on the calculated skin dose received, and on the dose to the gonads from scattered radiation. The radiation burden imposed on the gonads in males is approximates 2.5 mr/r skin dose. This is approximates 10 times as great as in female patients. The dose can be reduced considerably by Pb shielding, but in practice these protective procedures are not simple to perform. The gonadal radiation received from a thoracic x-ray study is approximates equivalent to the total background radiation normally received within a year. Bone marrow damage may also result from thoracic radiation, and some incidence of leukemia has been attributed to this cause. In order to reduce the possibility of radiation injuries from scattered radiation the focus-skin distance should never be less than 30 cm, and should be more than 45 cm, if possible. The radiation exposure period should be accurately timed and the amperage should not exceed 3 ma. The size of the radiation field should be kept as small as possible, and the sensitivity of the optical system and film should be as great as possible. Special precautions should be taken with children and pregnant women. Views should be taken only after the sixth gestational month, and after serious consideration. Children under 14 should be excluded from x-ray studies if possible. Protective clothing should have a Pb equivalent of at least 0.2 mm. The radiation doses received by personnel should be checked constartly by means of ionization chambers and film badges in order to ensure that the protective measures employed really keep radiation exposure down to within the permissible values.
