Contamination checking device and procedure for its use. A detecting probe (10) is connected to processing means (20) comprising means (24) of shaping the pulses supplied by the probe (10) under the effect of a radiation, counting means (26) and a microprocessor (36). The microprocessor (36) computes a mean value of the number of pulses counted per second and determines an instantaneous evolution indicator of the number of pulses counted per second. Application to the detection of alpha, beta, gamma and X radiation. <IMAGE>
