Abstract

Abstract: [Background] Environment gaseous radioactive iodine monitoring is important for nuclear power plant safety. ¹³¹I detection efficiency is an important parameter for environment gaseous radioactive ¹³¹I monitoring equipment. [Purpose] The aim is to explore an easy and simple approach which can estimate ¹³¹I detecting efficiency in iodine sampling cartridge based on ¹³³Ba source. ¹³³Ba has γ rays of similar energy characteristics as ¹³¹I and has long half-life. [Methods] According to some iodine detector sampling and detecting device, some work have been carried out including experiments and detection efficiency estimation and simulated calculation with SuperMC program under conditions similar to experiment. [Results] Detection efficiency experimental estimation results consistent with Monte Carlo (MC) simulation results within 6.0%. [Conclusion] The study suggests that the simple experimental method can be used to estimate the iodine sampling cartridge ¹³¹I detection efficiency.

Key words: ¹³¹I sampling cartridge, Detecting efficiency, ¹³³Ba point source, SuperMC program
