This invention relates to a particle detector comprising means (1, 2, 3)
of delivering electrical pulses and means (4) of counting delivered
electrical pulses.The detector comprises means capable of receiving and
transmitting electrical pulses originating from at least one second
particle detector to the counting means (4) and means capable of
transmitting electrical pulses that it delivers and electrical pulses
that it receives from the said second particle detector to the counting
means of a third particle detector.The invention is particularly
applicable to radiology (X-ray, radioscopy).
