[Test production of 60Co sealed sources of high specific activity (author's transl)].

To establish the production technique of 60Co sources with high specific activity, test production was started in 1967 by using JRR-3 and JMTR reactors. Two kinds of cobalt targets, a wafer type (diameter 8.0 mmxthickness 2.3 mm, 1.1g) and a pellet type (diameter 1.0 mmxlength 1.0mm, 6.9 mg) were used. The former was irradiated at a maximum nvt of 4.4x10(20… CONTINUE READING
