Technical factors in dental radiography in Hiroshima and Nagasaki
Diagnostic radiography is an important source of iontzing radiation exposure for populations throughout the world. More particularly, it is acting as a contaminant in the ongoing assessments of the effects of ionizing radiation from the Hiroshima and Nagasaki atomic bombs. Therefore, this extensive investigation was conducted to determine the magnitude of dental radiographic exposure. Most other large studies have dealt with the exposure of populations; this one is unique in that it focuses on the exposure individual patients receive. Interviews of 2,968 persons and records supplied by personnel of 207 hospitals and dental clinics established the frequency of and technical factors used in dental radiography. One of the findings of this investigation was that only half of the radiographic units had the filtration required by governmental regulations. The majority of dentists used intermediate rather than high-speed film. Darkrooms were a rarity, and instead, special film packets were most frequently used; processing solutions are injected into the packets, permitting instant processing in lighted areas. (auth)
