A method for measuring the coincidence count rate, using a time-to-digital conversion and an extendible dead time method with measurement of the live time. The count rate of coincident events between radiation detectors operating in parallel is measured, the time fluctuations of the coincident events are converted into digital form, and the extendible dead time method is used with measurement of the live time to eliminate all the other correlated events which may occur in a given detector. The time distributions of the time intervals separating the pulses are recorded, and the count rate of the coincident events is measured using recorded time distributions.
