A survey of dental x-ray units has previously been reported (1). The present paper is concerned with the radiation characteristics of fluoroscopes surveyed in the Philadelphia area and some of the problems involved in controlling unnecessary radiation exposure from their use. Method of Survey Measurements made on 81 fluoroscopes are included in the present study. Twenty-two units were owned by 8 hospitals4 and 4 city clinics, and the remaining 59 were in the offices of physicians engaged in private practice.
