a. Supplemental facility information provided in Appendix E.
b. For atmospheric releases, the dose is to the population within 80 kilometers (50 miles) of SRS. For aqueous releases, the dose is to the people using the Savannah River from SRS to the Atlantic Ocean.
c. The doses to the public from total SRS operations in 1993 were 0.25 millirem to the offsite maximally exposed individual and 9.1 person-rem to the regional population. These doses, when added to the incremental doses associated with the proposed action that are given in this table, are assumed to equal total SRS doses. For the maximum waste forecast (which gives the highest doses), the total annual doses to the offsite maximally exposed individual and the regional population would equal 0.58 millirem (0.25 + 0.33) and approximately 23.1 person-rem (9.1 + 14), respectively. The individual dose would fall below the proposed annual regulatory limits of 10 millirem from airborne releases, 4 millirem from drinking water, and 100 millirem from all pathways combined (proposed 10 CFR 834); the population dose would be lower than the proposed annual notification limit of 100 person-rem (proposed 10 CFR 834).
d. For the offsite maximally exposed individual, probability of a fatal cancer; for population, number of fatal cancers.
e. MEI = maximally exposed individual.
f. NA = Not applicable.
g. Atmospheric releases for MEI and population include contributions from offsite facilities, which contribute less than 6 percent to the atmospheric releases reported here.
