Abstract

Uranium in human bone, drinking water and daily diet has been determined by neutron activation analysis using the238U(n, γ)239U reaction. An improved scheme for the separation of the239U is proposed; with this scheme, after neutron irradiation in a 100 kW TRIGA reactor, a uranium content as low as 5·10−11 g can be determined reliably, rapidly and easily. A wide range of uranium concentrations, from about 0.1 ppb up to about 10 ppb has been found in the bones of normal Japanese. Water from several Japanese city water services, and the daily diet taken in two Japanese cities, have been found to contain an average 9·10−9 g/l and 1.5 μg per person-day uranium, respectively.
