Try again...I hit the wrong key on the last message. NEUTRINOS - Very interesting... The neutrino was postulated originally to provide conservation of momentum (when a body is in motion it stays in motion) in the weak nuclear force (radiation decay). The neutrino has no mass and does not interact with anything hence it was intially christened "the little neutral one" by Pauli. Typically, only one solar neutrino in every 10000000000 will interact with the earth. Therefore, the chances of an interaction between one person on the surface of the earth and a solar neutrino is, for all practical purposes, zero. Someome may have already stolen your idea because there is a theory that evolution resulted as a consequence of solar neutrino mutations. Neutrino experiments have been completed using nuclear reactors since they are produced in abundance from these sources. You can check to see if more people have PD who have worked or lived around nuclear reactors since it is virtually impossible to screen their production. However, if someone is exposed to a large dose of radition they generally die of cancer before they get a chance to develop PD.
