Transfer coefficients of radionuclides secreted in milk of dairy cows
- Naval Surface Weapons Center, White Oak Lab., Silver Spring, MD
This study simulated experimentally the transfer of radionuclides to milk of dairy cows on a worst-case situation using various radionuclides known to emanate from nuclear power stations and which have been detected on particulates. Two lactating Holstein cows were administered orally one gelatin capsule containing 10 radionuclides in water-soluble form per day for 14 consecutive days. Milk samples were collected and aliquots analyzed in a germanium lithium-drifted detector coupled to a 2048-multichannel gamma-ray analyzer to measure small amounts of complex mixtures of radionuclides. The transfer coefficients of the radionuclides were calculated when their secretion in milk reached or approached a plateau of concentration. The radionuclides and their transfer coefficients to milk were: chromium/sup 51/ less than 0.01%; manganese/sup 54/ 0.033 +- 0.005%; cobalt/sup 60/ 0.01 +- 0.002%; iron/sup 59/ 0.0048 +- 0.002%; zinc/sup 65/ 0.31 +- 0.07%; selenium/sup 75/ 0.29 +- 0.1%; antimony/sup 125/ 0.011 +- 0.003%; iodine/sup 131/ 0.88 +- 0.05%; and cesium/sup 137/ 0.79 +- 0.08%.
