CHAIRMAN MOSELEY: Universal Time, It's 30 minutes after the hour Coordinated and we will begin with a presentation by Dr. Ng on the Progress on Internal Dose Assessment Models, and he will be followed by Or. Anspaugh on another aspect of this subject. Dr. Ng. . ; OR. NG: Now, 10 ll (Exhibit LRA-1) May I have the second viewgraph now, please? this viewgraph (LRA-2) simply emphasizes that the documents by Hicks listed below have been published. Next viewgraph 12 (LRA=3) please. This viewgraph shows how the dose 13 calculations are carried out,-and it summarizes the basic calculations for 14 the dose in somewhat different form than I've previously shown, but it is 15 essentially unchanged. 16 exposure 17 location. 18 1 mR/hr at H+12. 19 is 20 individual and varies with the nuclide and event. 21 which varies with the age group, nuclide and organ.
