Surveying and recording the actual state of X-ray practice at periodic time intervals have a very important meaning from the standpoint of radiation protection. Designating the one week period of November 24 to 30, 1982 as a survey period, an actual state study on dental radiology practice was carried with the cooperation of all dental clinics and dental departments of general hospitals throughout Japan.
Comparison with the results of the previous study (1976) showed an improvement in the following areas: construction of exclusive X-ray rooms (25.7%), construction of darkrooms (47.4%), dissemination of automatic processors (47.1%), use of protective aprons (63.1%) and carrying of personnel monitoring dosimeters (19.5%).
