(a) Explain the function of the activator added in trace quantities to many inorganic scintillators. Why are activators not needed in organic scintillators?

(b) Assuming a decay constant of 230 ns, how much time is required for a NaI(Tl) scintillator event to emit 99% of the total light yield?

(c) The scintillation efficiency of anthracene is 6.01%. How much energy was deposited in the scintillator if 21095 photons with an average wavelength of 447 nm were detected?
