Spatial Distributions of 3H and 14C in the Shielding Concrete of KRR-2
Abstract
The depth distributions of total and activities were characterized for the activated shielding concrete from a decommissioning of KRR-2 using the commercially available tube furnace and a liquid scintillation counter. The correlation of measurement results between and gammer emitter was evaluated to apply for estimating radionuclide inventory of the concrete waste generated from decommissioning KRR-2. The detection limits for and are 0.048 and 0.028 Bq/g respectively. The specific activities of the and tend to decrease exponentially as the depth of the concrete becomes deeper from the surface. In addition, the and activities were in good correlation with the activities analysed for the shielding concrete of KRR-2.
