Some general perspective is provided concerning the orders of radiation dose equivalent levels associated with exposure of human populations to ionizing radiations from consumer products. The radiation dose from /sup 40/K of natural potassium content of deer is comparable to the radiation dose from /sup 137/Cs. ![]() ![]() Assuming an annual consumption rate of 20 kg gives an average individual whole body dose of 13 mrem, about 10% of local annual background level. Consumption of all edible meat from deer killed at SRP from 1965 to 1978 gives a whole body population dose of 196 man-rem from /sup 137/Cs. Analysis of these data enables the estimation of more » population dose from ingestion of the edible meat. The computerized SRP data base for each harvested deer includes age, sex, weight, cesium content, kill location, date, and the hunter's name. This value, based on measurements of 13,907 deer taken over 14 years (1965 to 1978), similar to the value obtained for 552 deer from other southeastern Coastal Plain locations, indicating the /sup 137/Cs content is due to fallout from the atmospheric testing of nuclear weapons rather than from SRP operations. The /sup 137/Cs content in deer killed during programmed hunts at the Savannah River Plant (SRP) has averaged 9.0 pCi/g.

The total population dose from an annual distribution of 8.3 x 10/sup 6/ timepieces containing H-3 in luminous paint was estimated to be 2200 man-rem/year from an annual distribution of 2.0 x 10/sup 6/ timepieces containing Pm-147, 390 man-rem/year. Under typical conditions, a maximum annual whole-body dose from H-3 of 0.9 mrem/year was estimated for repairmen, while a maximum of 0.3 mrem/ year was estimated for watch wearers from Pm-147. Potential radiation doses from the distribution, use, repair, and disposal of timepieces containing tritium (H-3) or promethium-147 (Pm-147) in radioluminous paint were estimated for the United States population.
