I just watched the movie 2012. Now I know it's just a movie and a bit of fantasy. What I want to know is, is there any type of radiation from the Sun that can penetrate a few miles into the Earth's crust and have some sort of effect on the rock down there. For example, can the amount of radiation in a rock be slowly increased over time only from radiation coming from the Sun? Do neutrinos become trapped in rock a few miles under ground and become detectable? Thanks for any answers.
