Improved Personnel Dosimeter. An improved personnel dosimeter was introduced on a Laboratory-widebasis in April 1998. The dosimeter’s increased accuracy in measuring the external neutron dose removedsome conservatism that had been previously used in estimating the dose, which resulted in lower reporteddoses. (The actual dose did not change, but the ability to measure it accurately improved.)Comparison with the Projected TEDE in the ROD. In addition to being less than the collective TEDElevels in 1993–1995, the collective TEDE for 2002 is less than the TEDE projected in the ROD. Theimplementation of war reserve pit manufacture, which was approved in the ROD, has not become fullyoperational at LANL. This contributed to lower doses than projected. The collective dose may increase oncethe pit manufacture program is fully implemented.Collective TEDEs for Key Facilities. In general, collective TEDEs by Key Facility or technical area aredifficult to determine because these data are collected at the group level, and members of many groups and/ororganizations receive doses at several locations. The fraction of a group’s collective TEDE coming from aspecific Key Facility or technical area can only be estimated. For example, personnel from the Health PhysicsOperations group and JCNNM are distributed over the entire Laboratory, and these two organizations accountfor a significant fraction of the total LANL collective TEDE. Nevertheless, the group working at TA-18 iswell defined, and the 2002 collective TEDE for the Pajarito Site Key Facility is 1.4 person-rem.Many of the groups working at TA-55 have been reorganized to include workers at other facilities.However, approximately 95 percent of the collective TEDE that these groups incur is estimated to come fromoperations at TA-55. The total collective TEDE for these groups in CY 2002, plus the estimated collectiveTEDE for the health physics personnel and JCNNM personnel working at TA-55, is 108 person-rem, which is66 percent of the total Laboratory TEDE of 164 person-rem.3.6 SocioeconomicsThe LANL-affiliated workforce continues to include UC employees and subcontractors. Table 3.6-1summarizes the workforce data from CY 1996 through CY 2002. As shown in Table 3.6-1, the number ofemployees has exceeded SWEIS ROD projections. The 13,524 employees at the end of CY 2002 are 2,173more employees than SWEIS ROD projections of 11,351. SWEIS ROD projections were based on 10,593employees identified for the index year (employment as of March 1996). The 13,524 total employees atthe end of CY 2002 reflect an increase of 1,144 employees over the 12,380 employees reported in the 2001Yearbook (LANL 2002a).Table 3.6-1.
