The building is kaolin. Does it have radiation? District 15 years ago is a kaolin processing plant, there will be residual radiation it?
Although people can not over accept radiation, but if people are completely out of radiation environment, it is also unhealthy. For example, all the known radon spa, is actually a kind of radiation recuperation.
The first thing to stress is that the world is full of radiation, whether it's land, sea, mountains, fields, rocks, soil...... We call it the background radiation intensity".
There is no radiation pollution in kaolin itself, but it is impossible to be consistent with the background radiation intensity according to the soil and rock composition in different areas. In other words, the radiation intensities of kaolin and kaolin are not exactly the same. Specific to your place is excessive radiation, and nothing to do with kaolin itself.
