Alkaline phosphatase activity in dog blood serum was studied for two years following separate and combined exposure to gamma radiation (6.45 to 51.6 mC/kg) and inhaled submicron 239Pu oxide, containing 25 per cent of 241Am, in chronically effective amounts (approximately 7-10 kBq/kg). Alkaline phosphatase activity was of an undulatory character, and the significance of changes depended upon the kind and the level of radiation as well as the time lapsed from the start of the exposure. With the combined exposure to gamma and alpha radiation in the doses used, no enhancement of the effect was noted as compared with the action of each factor applied separately. |
