The Pilot Survey Result on the Radioactive Concentration Measurement in Charcoal Filter Waste

Abstract

10336drams(50L dram) of granular active carbon, which were taken out from charcoal filters used in medical institutions, are stored at the Kaya Memorial Takizawa Laboratory. Samples were taken from 728 drams of them and radioactive concentration was measured. Measured results of gamma-emitting radionuclides in all the samples were below the minimum detection limit.
