Analytical characterization of some nuclear reactions induced in thin samples axially moving in front of disk-shaped isotropically emitting sources

The paper deals with the theoretical characterization of some nuclear reactions induced in an element of target area moving axially in front of a flat disk-shaped source isotropically emitting in non-dispersive media. Some particular cases of motion are theoretically investigated in order to establish analytically the level of nuclear mutations or the radioactivity acquired in given irradiation periods.
