I was reading about Earnest Lawrence and a question dawned onto me; Lets say you bombarded a metal, lets say iron or copper, with high energy protons coming from a cyclotron. The protons going from the "dees" into an accelerating vacuum tube with the specimen at the end. Would the proton beam make the item decay into another element? Would the decay/transmutation into be quick or take a long time, and would it make the item dangerously radioactive. (defining dangerous as giving off ALPHA radiation and relatively few Gamma Rays.) Would it instantly make it a new element? Please tell me, using the examples stated above. This is TOTALLY HYPOTHETICAL so moderators don't worry.
