การตรวจสอบความเข้มข้นของก๊าซเรดอนเพื่อคาดคะเนการเกิดแผ่นดินไหวบริเวณรอยเลื่อนเขาเด่น จังหวัดสุราษฎร์ธานี

Abstract

The purpose of this research was to measure the level of radon gas by solid state nuclear track detector method. Along the Khaoden fault line Surat Thani Province, a distance of 23.2 kilometers, with 12 measuring stations collecting samples 12 times between August 2019 and August 2020 to predict the likelihood of an earthquake around the fault line. It was found that The KDF2, KDF3, KDF4 and KDF12 measuring stations have 2-10 times the radon concentration several times higher than the reference location. Which is prone to earthquakes Therefore, such measuring stations should be used as earthquake monitoring stations where radon gas should be continuously monitored.
