PART TliREE RADIATION DOSE DUE TO GASEOUS AND LIQUID EFFLUENTS DC00A9 I _
RADIATION DOSES I. Radiation doses elue to radioactive liquid effluents The radiation do.e contributions due to releases of radioactive liquid effluents to the total body and each individual organ for the maximum exposed adult ha.ve been calculated in accordance with the methodology in the Offsite Dose Calculation Procedure. Dose contributions, listed in Table 7, show conformance with technical specification 4.11.1.2.
II. Radiation doses due to radioactive gaseous effluents The radiation dose contributions due to radioactive gaseous effluents at the site boundary for the land sectors have been calculated in accordance with the methodology in the Offsite Dose Calculation Procedure. The meteorology concurrent with the time of discharge were used in'these calculations. In addition to the site boundary doses, the dose to all age groups at the nearest residence within the low population zone for each of the land sectors and a five mile infant milk dose in each of the land sectors is included. Dose contributions, listed in Table 8, for the first and second quarters show conformance with technical specifications 4.11.2.2 and 4.11.2.3.
III. 40 CFR 190 Considerations The releases of radioactivity in liquid and gaseous effluents during 1985 resulted in doses that are small percentages of the technical specification limits as shown in Tables 9 and 10. This coupled with the fact that there are no other uranium fuel cycle sources within eight kilometers of the Diablo Canyon Nuclear Power Plant shows conformance with 40 CFR 190.

NOTES:
- 1. This represents the maximum dose of age groups, organs, and geographic locations.
- 2. The ocean sectors SSE, S, SSW, SW, WSW, W, and WNW, are not included.
- 3. Radiofodines, Radioactive Material in Particulate Form and Radionuclides Other Than Noble Gases With Half-lives Greater Than Eight Days.
- 4. The inhalation, ground plane and animal-meat pathways are included in this dose calculation.
- 5. This location is a vegetable farm located tnroughout the ESE sector starting at 2 miles.
- 6. The inhalation, ground plane, animal-meat and vegetable pathways are included for this location. An occupancy factor of 0.5 was used for the inhalation and ground plane pathways. The child age group had the highest calculated dose for this location.
