Use and workload factors in dental radiation-protection design
Abstract:
A dosimetric and photographic record of the pattern of radiation on the walls of a dental x-ray operatory was obtained. This indicates that there is an overlap of the radiation fields with "hot spots" on the side wall opposite the patient's head, with the rest of the room receiving minimal exposures. In the course of this investigation, it was found that use of the long-cone x-ray machine resulted in less radiation reaching the walls of the room. The presently accepted concept of mAs per week proves to be less relevant than the number of films being taken.
