c. E Interpretation of Dose Summ:ry Tr.ble
- E'
'U The Dose Summary Table (Table 1) presents the maximum hypothetical doses to an individual and general population resulting from the release of gaseous' and liquid effluents from TMI-2 and EPICOR 2 during the third quarter reporting period of 1982. I i 1. Liquid (Individual) The first two lines of Table 1 present the maximum hypothetical dose to an individual. Presented are the whole body and critical organ doses. Calculations are performed on the four age groups and eight organs recommended in Regulatory Guide 1.109. The pathways considered for TMI are drinking water, consumption of fish, and standing on the shoreline influenced by TMI effluents. The latter two pathways are considered to be the primary recreational activities associated with i the Susquehanna River in the vicinity of TMI. The " receptor" would be that individual who consumes water from the Susquehanna River, fish residing in the plant discharge, while occupying an area of shoreline influenced by the plant discharge. After calculating the doses to all age groups for all eight organs resulting from the three pathways described above, the Dose Summary Table presents the maximum whole body dose and affected age group along with the organ and associated age group that received the largest dose. For the third quarter of 1982, the calculated maximum whole body l dose received by anyone would have been 1.26E-05 mrem to an adult. I Similarly, the maximum exposed organ would have been 2.00E-05 mrem to the liver of a teen. 2. Caseous (Individual) There are seven major pathways considered in the dose calculations for gaseous effluents. These are: (1) plume, (2) inhalation, consumption of (3) cow milk, (4) goat milk, (5) vegetables, (6) meat, and (7) standing on contaminated ground. Lines 3 and 4 present the maximum plume exposure at the site boundary. The notation of " air dose" is interpreted to mean that these doses are not to an individual, but are considered to be the maximum dose that would have occurred at the site boundary. The Dose Summary Table presents the distance in meters to the site boundary in the affected sector (compass point). It should be noted that real-time meteorology was used in all dose calculations for gaseous effluents. .~ With respect to the gaseous release for the third quarter of 1982, j the plume exposure at the site boundary would have been 2.31E-04 mrad and 2.62E-02 mrad, gamma and beta dose respectively, i i _m,_ .,a Page 2 of 2 ^ Lines 5 and 6 present the calculated dose to the closest receptor (individual) in the affected sector (s). The location of the receptor is described,by both distance (meters) and direction from the site. Plume exposure to an individual, regardless of age, from gaseous effluents during the third quarter were 1.46E-05 mrem and 1.75E-03 mrem, whole body and skin exposure, respectively. The Iodines and Particulates section described in line 7 represents the maximum exposed organ due to iodine and particulates. This does not include the whole body plume exposure which was separated out by line 5. The doses presented in this section again reflect the maximum exposed organ for the appropriate age groap. The third quarter dose due to the iodines and particulates would have resulted in a maximum dose of 1.37E-04 mrem to the liver of a child residing 3200 meters from the site in the NNW sector. No other organ'of any age group would have received a dose greater than this. 3. Liquid and Gaseous (Population) Lines 8-11 present the person-rem doses resulting from the liquid and gaseous effluents. These doses are summed over all pathways and the affected populations. Liquid person-rem is based upon the population encompassed within the region from the TMI outfall extending down to the Chesapeake Bay. The person-rem for gaseous effluents are based upon the 1980 population projections of the FSAR and consider the population out to a' distance of 50 miles around TMI. Population doses are summed over all distances and sectors to give an aggregate dose. Based upon the calculations performed for the third quarter, liquid effluents resulted in whole body population dose of 2.8E-06 person-rem with a maximum critical organ population dose to the liver of 5.6E-06 person-rem. Gaseous effluents resulted in a whole body dose of 3.2E-01 person-rem. The maximum exposed critical: organs were GI tract, liver, kidney, thyroid, and skin. This resulted in a dose of 3.2E-01 person-rem for each organ. e Pag ~e 1 of 1
