Practical suggestions for lowering patient exposure are offered to radiologists. Maximum permissible radiation doses pertaining to somatic and genetic hazards are given. The measured average gonadal doses of radiation during a 1-min lung examination were 1.8 mr for men, 0.6 mr for women, and 20.0 mr for children aged under 1 year. X-ray pictures may be taken from a distance of 2 m to avoid distortion; in this case, however, direct radiation exposure covers 1 m, including the gonads of most patients. A 12cm dia. cone will expose a circular area of 70-cm dia., leaving the gonads outside the direct irradiation zone. A 40 x 50-cm lead-rubber apron should be worn below the level of the lower ribs for gonadal protection. When a series of exposures is made, a 12-cm cone should be used, and the head, lower half of the body, and half of the lungs should be shielded. The radiation doses reaching the gonads in such series are. without the cone in place, 155 mr for men and 20 mr for women, with the cone, 45 and 12 mr, respectively; with good protective shielding, less than 1 mr. The exposure data available for bronchiography are similar but no accurate information is presently available. (BBB)
