Hello all, a new user here. I am in need of some very basic information that seems to be impossible to find. I need to know the typical background radiation on the earth's surface (cosmic, solar, natural, manmade), particularly flux rates and energy. The closest I have come is a flux rate for neutrons with no energy information given, and also dose rates which I do not need. If anyone can provide a link or point me to a text with this information, that would be great!!
