atmospheric nuclear weapons tests. The sheer volume of morning reports made the task time-consuming. The ANTPR approach, like that of the other NTPR teams, evolved in response to DNA directives, along with Congressional and public needs. By August 1979, the ANTPR team had shifted its primary emphasis from research on individuals to responses to specific groups, such as the over-25-rem and over-5-rem participants, the volunteer observers, and the VA claimants. Section 2.3.3 presents statistics on these efforts. In late 1982, the ANTPR data entry staff decreased in number, as personnel and financial resources were redirected to handle new priorities within the Army, such as the Agent Orange Task Force. At about the same time, programming and data entry errors created problems in the ANTPR computer system. In early 1983, the ANTPR Program Manager sent a memorandum to the DNA NTPR Program Manager indicating that these problems, along with the decrease in staff, had resulted in considerable curtailment of data entry within the past quarter. DNA and the Army worked together in the latter half of 1983 to identify the difficulties and prescribe solutions. In a meeting with DNA on 31 January 1984, the Army agreed to provide funds to contract for technical support, especially to purify the ANTPR data base. The contract was awarded in September 1984, and work commenced immediately toward accomplishment of the five major ANTPR tasks, beginning with purification of the data base. Subsequent tasks involve identifying personnel and units, determining radiation exposure and entering information into the ANTPR data base, notifying test participants, and responding to requests for information from veterans, VA, and Congress. With the assistance of its contractor, the ANTPR should meet its objectives by the end of 1987. 2.3.2 Resources. The ANTPR has had five chief administrators: Colonel Victor J. Hugo, February 1978 to September 1978; Colonel David P. Lucke, September 1978 to October 1979; Lieutenant Colonel Darwin M. Way, 17 October 1979 to June 1980; Mr. Waldemar A. Anderson, June 1980 to March 1981; and Mr. Richard S. Christian, March 1981 to present. 35
