1 The involved worker is a worker associated with operations of the A/D facilities. The estimated number of involved workers considered at risk for exposure is 300 for the downsize/consolidate alternative. The 1,070 workers for the No Action alternative are all considered at risk for exposure.

2 The radiological limit for an individual worker is 5,000 mrem/yr (10 CFR 835).

3 The noninvolved worker is an onsite worker unassociated with operation of the A/D facilities in question. The estimated number of noninvolved workers is 50.

4 The total site workforce is the sum of the number of involved and noninvolved workers. The estimated number of workers in the total site workforce is 350 for the downsize/consolidate alternative and 1,070 for the No Action alternative. Source: DOE 1993n:7; PX MH 1995a.
