GAMMA又是什么？还有没有安全的地方住了啊？

Natural Resources Canada publishes gamma radiation maps for much of Canada.

Gamma-ray spectrometry can be used to evaluate the first factor for radon in homes, source material capable of producing radon, by identifying uranium bearing materials at the earth’s surface, which may generate radon.

Studies have shown that ground concentrations of uranium determined by an airborne gamma-ray spectrometer provide a qualitative, first order approximation of regional variation in indoor radon levels and can be used to identify and outline high risk areas. The only way to know the level of radon gas in your home is to have it tested.
