Dear Dr. Till:

This is in reply to your letter dated September 6, 2001. The following responses are provided with respect to the questions posed by the National Research Council Committee to Review the Dose Reconstruction Program of the Defense Threat Reduction Agency and the Board on Radiation Effects Research. Per our conversation with NAS’ Dr. Al-Nabulsi on 7 September 2001, we indicated it would be appropriate for DTRA to respond to questions 5, 6, 8, 9, 10, 11, 12, 13, 14, and 16 and provide comments on the flow chart pertaining to DTRA responsibilities. We recommended questions 1 through 4 should be referred to Department of Veterans Affairs (VA), Office of the Undersecretary for Benefits and questions 7, 8, 10, and 15 to VA, Office of the Undersecretary for Health.

Question 5. When a claimant is referred to JAYCOR, is the dose of record then sent to VA and DTRA or only to DTRA?

Reply: When a dose is provided for a claim referred to JAYCOR, the dose information is given to DTRA for review and approval. DTRA then sends the dose information to both the VA and the claimant. In cases where the claimant’s address is not known, DTRA requests the VA to forward a copy to the claimant.

Question 6. Under what circumstances is the file referred to SAIC for a dose and in what circumstances is this not done?

Reply: Claimant files not referred to SAIC are under the following circumstances:


non-participant cases (these cases are not verified participants);


presumptive cases (these cases do not require dose information); and
