It produces the data of decay pulse serials of radon and its daughters by using matlab , it conforms the decay law of the radon and its daughters, and the time-interval of the neighboring pulses conforms the exponential distribution law as well And then we discriminate 219Rn from radon isotopes by using a software delayed coincidence counter, in which the best time to gate-time is about 6ms in the system of delayed coincidence measure, it is helpful to the study of the radon isotope...
