Radiation hazard control report

This is a report on the radiation hazard control from April 1994 to March 1995 in Atomic Energy Research Institute, Kinki University. The subjects of the radiation hazard control were a total of 112 occupationally exposed personnel consisting of 57 teachers in this institute and the faculties of Science and Technology, Pharmacy and Agriculture, 13 students in the faculties of Science and Technology, and Agriculture who utilized the reactor building for thier graduation research, and 42 students in the faculty of Science and Technology as the exposed personnel involved in Radiation Hazard Prevention Act. The nuclear reactor was operated under the conditions of the maximum heat power of 1 W, the integrated heat power of 333.25 W·hr and the total operation time in 1994 was 617.96 hrs. The periodical inspections for the reactor building and an on-the-spot inspection for radiation facilities based on Radiation Hazard Prevention Law were carried out in April and September in 1994, respectively by Science and Technology Agency and the periodical RI test by Nuclear Safety Technology Center was conducted in February, 1995. These facilities have passed all the inspections without any troubles. The results of the periodically conducted inspections on radiation hazard control were presented in this report. The data of the environmental radioactivities around the reactor building and the tracer·accelerator building suggest that there is no influence by the radioactive nuclides with long half life except natural nuclides.
