Dm. Timus et al., ACTIVITY CHARACTERIZATION OF THIN SAMPLES MOVING IN FRONT OF DISK-SHAPED ISOTROPICALLY EMITTING SOURCES, Journal of Nuclear Science and Technology, 31(6), 1994, pp. 590-595
The paper deals with the activity acquired by an element of target are
a moving parallel to a flat disk-shaped source isotropically emitting
in nondispersive media. Some particular cases of motion are theoretica
lly investigated in order to establish analytically the activity acqui
red in given irradiation periods.
