3. Korea Institute of Nuclear Safety 1. Background - 1 -  Needs improved system for radiation safety regulation The number of radiation workers is increasing every year. The use of radioisotope(including RG) is diversified to the various fields There are difficulties in protecting workers from radiation exposures effectively.  Because regulatory activities and the management of occupational dose records are separated to KINS and KRIA.  To be selected as a key task in a report of national policies in 2002

4. Korea Institute of Nuclear Safety 2. Purposes and Functions - 2 - - Support regulatory works - Produce data for the dose reduction - Dose assessment for the categories - Q/A for the personal dose information - Support regulatory works - Produce data for the dose reduction - Dose assessment for the categories - Q/A for the personal dose information - Privide risk information V/V for regulatory activities - Link international network - Privide risk information V/V for regulatory activities - Link international network Improve Safety Regulation System Improve Safety Regulation System Developing indicator for the risk based radiation protection scheme Development and In depth analysis for the dose Dose Reduction Dose Assessment and Evaluation Integrated management for the radiation worker information Final Goal Functions
