Although we selected "optimisation of radiological protection" above "documents" section, We would like to comment for all 5 foundation documents as "General Comments" General Comments We welcome the openness of the ICRPfs approach regarding its draft report of 2005 recommendation and its five foundation documents. As along with ICRPfs new approach, we sent our following comments to ICRPfs secretariat last December. Broadened the meanings of gdose constraintsh Disappearance of gINTERVENTIONh Definition of ea single sourcef especially for Power Plant Limitation of LNT hypothesis Disappearance of Action level for Radon Unfortunately, we can hardly find answers of these important comments in five foundation documents. Similar suggestions were also sent by many major countries and international organizations. In order to meet and facilitate the philosophy of gSTAKEHOLDER INVOLVEMENTh, these important comments were supposed to be answered clearly.
