1 Includes impacts from all site operations.

2 The applicable radiological limits for an individual member of the public from total site operations are 10 mrem/yr from the air pathways, 4 mrem/yr from the drinking water pathway, and 100 mrem/yr from all pathways combined (DOE Order 5400.5).

3 Natural background radiation levels to the average individual is 334 mrem/yr; to the population within 80 km (50 mi) in 2030 is 95,300 person-rem. Source: PX DOE 1995d; PX MH 1995a.
