Studies on Radiation-Resisting Paints for Concrete Structures in Nuclear Powerplants. Part 3.

摘要

In order to protect concrete structures in nuclear power plants from radioactive contamination, it is desirable for the irradiation-resisting paints applied on the concrete surface not only to have resistance to irradiation and hot water, but also low contaminability and high decontaminability. The irradiation contaminability and decontaminability were examined with respect to five kinds of epoxy paints and two kinds of phenol-modified paints using 3 kinds of radioactive nuclides ( exp 137 Cs exp + , exp 60 Co exp 2+ , exp 144 Ce exp 3+ ) before and after gamma -ray irradiation. The results are presented. (ERA citation 03:030942)
