In diluted, watery solutions chlorine dioxide is a free radical. At high concentrations it reacts strongly with reducing agents. Chlorine dioxide is an unstable gas that dissociates into chlorine gas (Cl 2), oxygen gas (O 2) and heat. When chlorine dioxide is photo-oxidized by sunlight, it falls apart.

2017-2-2detection rate of 91% is achieved, with seven false alarms recorded over 3 days, and an average detection delay of 108 s. The localization results show an accuracy of 5 m. Recommendations for future explosive gas sensor design are then presented. Index Terms—Distributed detection, gas leak detection, industrial wireless, low power networks ...
