4. Measurements and Approximations of Total Radioactivity

a. Fission and activation gases (1) These gases, excluding tritium, are collected in a Marinelli type beaker, specially modified for gas sampling, steel bombs, or glass vials and counted on a Ge(Li) detector for t s _deipal gammn emitters.

(2) Tritium gas is collected using a bubble apparatus and counted by liquid scintillation.

b. Iodines - are collected on a charcoal cartridge filter, and counted on a Ge(L1) detector.

c. Particulates - are collected on filter paper and counted on a Ge(Li) detector.

d. Liquid effluents - are collected in bottles and counted on a Ge(Li) detector.

a.

0-50 mile meat, milk and vegetable production, water usage information; location of the nearest individuals and pathways by sector out to

~ 5 miles - source: Appendix I analysis, NRC Docket No. 50-346, Evalua-tion of Compliance with Appendix I to 10CFRS.0, June 4,1976, Davis-Besse '

10. Tabl'es 11 through 18 present the X/Q values associated with the dose values presented in Tables 6 through 10.

Based on the information presented above, it is concluded that the doses to individuals are well below the dose objectives of Appendix I to 10CFR50.
