222Rn (radon) is the major radioactive gas in volcanic area. The study of radon concentration variations areas has been considered as a useful tool to investigate activity one Tatun Volcano Group, where close Taipei basin and exhibits active fumaroles hot springs, was chosen for first time systematical Hsiao-You-Keng hydrothermal area northern Taiwan. In addition soil CO2 flux compositions, concentrations were measured situ by an analogous sensor. sensor developed separate electronics from measurement chamber, which contains detector preamplifier completely covered epoxy, can be used aggressive environment. Combined with composition helium isotopic data, we conclude that mainly carried gases. Therefore, it good proxy monitoring magma this A station newly setup such purpose preliminary data will presented study.
