Investigations for VA Claims. The NNTPR has provided information on participation and dose to the Veterans Administration for 1,045 claims filed for compensation benefits by Navy personnel who believe their diseases or disabilities were caused by their exposure to ionizing radiation during atmospheric nuclear weapons testing (5). In compiling data for the VA, the NNTPR developed over 360 unit histories, usually from one to three pages, for the ships, squadrons, and staffs associated with the oceanic nuclear tests. These histories specify unit locations and activities during the test series, unit dosimetry data, and, when available, the radiological conditions present (9). Correspondence Summary. In fulfilling its obligations, the NNTPR has processed considerable amounts of correspondence. The following table summarizes both the type and volume of correspondence for selected years (9): NNTPR Outgoing Correspondence Totals Type Personal Inquiries VA Request Congressional Request from Family Request from Employer Miscellaneous Memorandum for the Record FOIA Attorney’s Request Special Medical Letters Over-5-rem Letters Medical Records Request Form Letters Final File "A" Letters Non-Participant Letters Total 2.3 t 1978 1980 1982 1984 1985 1986 11 14 8 1 0 291 33 0 0 0 0 1,226 325 46 25 12 58 114 2 13 586 163 217 132 42 13 8 262 58 35 7 0 13 218 212 17 9 2 227 59 16 6 0 0 107 223 20 18 2 164 16 24 4 0 4 47 62 8 1 0 30 1 2 2 0 0 0 0 0 552 0 0 89 5,170 523 124 6,632 271 135 182 9 127 170 4 358 3,605 6,590 7,793 910 456 0 483 21 0 2 2 ARMY NTPR EFFORTS.
