Hot spring pool introduction: Taishun Radon Spring is formed by water on the surface of the earth that passed through a depth of 5,000 meters in the earth's crust for 38 years, circulated everywhere, and then erupted from the eye of the hot spring. It was formed by Chongzhen in the Ming Dynasty. "Taishun County Chronicle" records: "The ancient eye hole is located next to the fiery stream in Yayang." During the Wuyin period of Guangxu in the Qing Dynasty, it was stated in "Taishun Dividing Records": "The soup spring is next to the Shuikou Cave in Yayang. It is commonly known as the Fiery Stream. The spring rises from the small stone pool next to the stream. It is as hot as soup in all seasons, and it is especially hot in winter. ". After repeated testing by the Zhejiang Provincial Geological and Mineral Team, the temperature of the radon spring is 62 degrees Celsius, the radon content per liter is 15 Emmans, the fluorine content is 20 milligrams, and the water output of the spring is 500 tons/day. It has been scientifically confirmed that Taishun Radon Spring is a high-temperature and low-mineral spring. It is a large hot spring that contains radon, fluorine and silicon, and weakly radiates more than 40 kinds of trace elements.
