Abstract
- The effects of incorporating tritiated water into a <superscript>14</superscript>C-sampling system in sample preparation and <superscript>14</superscript>C activity measurement by liquid scintillation counting were investigated. Experiments derived the limit of water content in the prepared sample, and also demonstrated that <superscript>14</superscript>C activity can be determined without any interference from <superscript>3</superscript>H contamination for a clear-sample solution. The results enabled us to estimate the permissible relative humidity of air required for accomplishing sample preparation and <superscript>14</superscript>C activity measurement. These showed that for sampling of air with less than the permissible relative humidity, total <superscript>14</superscript>C activity in airborne effluent can be evaluated accurately without dehumidification of air.
