Almost everything is radioactive, at least to some extent. I strongly suspect that most geologists know this. The air is radioactive because of C14. Our bodies are radioactive due to K40 and others. It is mostly a matter of degree of how radioactive things are. Most rocks are slightly radioactive. Some rocks are quite radioactive. A few rocks are very very radioactive. I don't know how radioactive the rock where the geothermal is being proposed is. It would be foolish not to find out what sort of radiation release would be generated before significant development of the geothermal field. However, chemical risks are probably higher: arsenic, lead, etc. -- Phil Hays
