Experimental tests of dead-time corrections

Experimental tests of dead-time-induced counting losses in radiation or particle detection using a relatively simple electronic device are described. A calculated correction described earlier, applicable in certain cases of pulsed radiation, is confirmed up to high fractional counting losses. The well-known correction formulae for constant, extending or non-extending dead times in the case of continuous radiation can as well be confirmed within the precision limits of the device. The technique may be useful in instruction laboratory courses.
