Small ion pulse ionization chamber for radon measurement in underground space

Appl Radiat Isot. 2024 Oct:212:111467. doi: 10.1016/j.apradiso.2024.111467. Epub 2024 Aug 5.

Abstract

Radon, prevalent in underground spaces, requires continuous monitoring due to health risks. Traditional detectors are often expensive, bulky, and ill-suited for humid environments in underground spaces. This study presents a compact, cost-effective radon detector designed for long-term, online monitoring. It uses a small ionization chamber with natural airflow, avoiding the need for fans or pumps, and includes noise filtering and humidity mitigation. Featuring multi-point networking and easy integration capabilities, this detector significantly enhances radon monitoring in challenging, underground conditions.
