Actual conditions of the radiation protection in 20 dental offices were investigated from December 1979 to March 1980. The findings of this investigation are reported hereunder : 1. Shielding rooms used exclusively for X-ray examination were found in 7 dental offices only. A simple protective barrier or no protection devices are seen in the rest. 2. Exposure dose measured during production of a maxillar molar radiograph varied from 200mR to 1000mR or more according to the judgement of the individual practitioners. 3. However, most of the types of the cones and timers of the dental X-ray machines were found to be in compliance with paragraphs 113 and 115 of ICRP publication 16. The exposure field size of these machines were mostly less than 60mm in diameter at the end of the cone. Generally, most of the equipment meet the requirements of the ICRP publications. 4. Also from the observation of other matters for investigations, it was noted that the radiation protection in the general dental offices is rather insufficient or unattended to due to economical reason and other difficulties peculiar to the dental treatment.
