Abstract

This paper introduces the KRISS-Rn4, a high-sensitivity radon monitor with four detection cells, installed within a walk-in type radon calibration chamber at KRISS. The KRISS-Rn4 exhibits enhanced energy resolution through channel-by-channel signal processing and data acquisition. Results reveal that it achieves lower statistical fluctuations and faster response times in monitoring test atmospheres compared to commercial devices.
