My X-ray working hystory has become 50 years at the end of April, 1980. At this chance, the following data were summarized ; the case numbers of X-ray photographs (517,132 cases), the total amounts of radiation exposure dose (66.85 roentgen) and the results of blood test, which were experienced during past 50 years. The amounts of exposure dose during 35 years till 1960 were measured using my own method, which measured the film blackning as 30 milli-roentgen per week by certain standard method. After 1961 till 1980,the exposure dose were recorded using that of the film-badge service of Nippon Hoan Yohin Kyokai. The total amounts of exposure dose during 50 years were about 1/4 of D=5 (N-18). The results of blood test during last 27 years were found to be mormal values. Then, it is happy to say that my body has been protected completely, from radiation hazard as a result of taking radiation protection and checking blood test always at my daily radiation works. The data of my own experiences during 50 years are summarized and reported in this paper.
