Abstract
UNSCEAR has proposed the radiation protection for human health to United Nations from the scientific results. For example, it is very hard to clarify the justice uncertain parts of radiation reports on human being of radiation accidents such as Chernobyl. In our JRRS, we has established special symposiums many times and published the special issue in JRR to seek accurate scientific results. In JRRS, we have studied about the radiation effects and risk estimation from the biological radiation effects of low dose and low dose-rate. On the other hand, we have no enough scientific results about risk estimation of radiation diagnosis. Therefore we have to study the field as soon as possible. On the other hand, our Japanese group has published many excellent papers about the biological effects of high LET radiations to normal tissue and tumors. These fields are focused from the word. In addition, recent progressed molecular biological techniques have contributed to the mechanisms of mutation induction and cancer events by study for cancer related genes and DNA repair. Especially, new approach such as mutagenic and knockout mice also has brought very important information of radiation effects. We are glad to accept the proposal about the projects which UNSCEAR requires. We have to challenge how we have to establish the proposed projects and prepare the grants for them in Japan. Then we have to produce high quality scientific products and arrange to summarize them. Finally I expect Japanese radiation scientists produce many important scientific papers which UNSCEAR cannot ignore.
