Abstract

Radioactivity of water increased linearly with dose when aqueous solution of 3H-formate (2 μCi/ml and 2×10−8 M) was irradiated with γ-rays in the presence of oxygen. The increase of the radioactivity was found to be reciprocally proportional to the non-labeled formate concentration where the amount of 3H-formate was kept invariable. Addition of ferrocyanide and 2-propanol, effective OH-radicals scavengers, depressed the radioactivity increase to near zero. These facts show that the abstraction of tritium from 3H-formate by OH-radicals causes the increase of the radioactivity of water. A competition method to measure relative rate constants for reactions with OH-radicals was deviced on the present results. Some values obtained by this method were in agreement with published data.
