Slow scintillation time constants in NaI(Tl) for different interacting particles
Very large thallium doped sodium iodide crystals operated underground and in very low background environment in the context of a dark matter search experiment have been used to determine scintillation components in the tens of ms range in the light pulse induced by different interacting particles: gammas/muons and alphas.
