Abstract

In order to determine,99Tc in the atmosphere, we analyzed a dried-up deposition sample obtained from rain and dry fallout. We carried out tracer experiments to investigate the loss of99Tc during preparation of the sample by evaporation and drying and to examine a suitable separation method for measurement of the nuclide in the sample by using ICP-MS. The results showed no remarkable reduction of Tc during evaporation to dryness. The volatilization and trapping method with a combustion apparatus gave a clear and easy separation of Tc with a recovery of 77%.
