Sampling and monitoring of carbon-14 in gaseous effluents from nuclear facilities: Literature survey

Margit Snellman

Research output: Book/ReportReport

Abstract

This study reviews the possibilities for sampling and monitoring C-14 in gaseous effluents from nuclear facilities. After oxidation of various forms of carbon-14 in the off-gas into CO2 three main processes for trapping are used either separately or in combination. These are sorption, freezing and chemical processes. Absorption in alkaline solutions or solids or molecular sieve adsorption are the most frequently used methods. The main counting methods used are gas proportional counting and liquid scintillation counting.
