【Is it true that the earth emits the radiation?】

《The radiation which has generated from the earth's inside》

Needless to say,the neare being inside the earth,it means the deeper going down to into inside the earth,the stronger the radiation becomes.⚠

In addition,the radioactive material itself sometimes leaks from the earth's inside.One of them is radon.It's the gaseous body.☝

When the radioactive material,radium,is broken in the earth's core,the radon gives off.The radon also releases α rays,and changes into polonium.⚠

In a word,the radon is a source which releases the α rays.It's said there are a lot of the radons in a basement made of stone,so some people point out the radon has nature of causing cancer.💀

It's also said that workers in a place of uranium mine suffer from damage of being exposed to the radiation.💀

《A hot spring's radioactivity》

The radon is the gaseous body which is easy to be melted into water.😃
