Abstract
Screening programs to detect scoliosis in the adolescent population are active in most communities. Of children screened, 2% will be referred for treatment or observation. Increasing concern has been voiced regarding the amount of the potential effects of the radiation administered in screening programs. Radiation dosage was directly measured on 19 children participating in an established school scoliosis screening program, using LiF thermoluminescence dosimeters. Mean gonadal doses were 19 mrem in males and estimated at a maximum 95 mrem in females. Mean entrance skin dose was 174 mrem. A lack of uniformity in the radiographic techniques employed by individual technicians was identified. The measured doses were within established acceptable limits and were comparable or below the average dose of 100 mrem received annually by the general public from the environment.
