An apparatus for monitoring radio-active contamination comprises an enclosure 1 containing a rotatable support 3 for carrying an article 4 to be monitored which support can be tilted out of the enclosure (Fig. 2 not shown) for location and withdrawal of the article, and a plurality of radioactive particle detectors 11 mounted around the article 4 for exploring its surface during one complete revolution of the article on the support, the detectors 11 being arranged to operate successively or simultaneously. The detectors 11 which are preferably halogen counters which function on the Geiger mode or proportional mode according to the value of their operating potentials which are adjusted by a switch 12, are placed so that each monitors one part of the article 4 when it is rotated by the operation of a crank 10 acting through a rod 8, a worm-wheel 9 and pinion 7. The detectors are arranged to operate simultaneously or successively according to the position of a switch 16. After insertion of the article 4 the switch 12 is moved to a position in which the detectors function on the proportional mode so as to detect α-particles and the switch 16 is operated so that the detectors operate simultaneously; the article is then rotated through 360 degrees and the output from the detectors 11 is fed through an amplifier (not shown) to an integrator type pulse counting scale which gives the amount of alpha contamination in pulses/second. The switch 12 is then moved to the position where the detectors function on the Geiger mode to detect #-and y -radiation in which position the amplifier is disconnected from the circuit and the measurement of # and y contamination is measured as the article is rotated through a further 360 degrees. The switch 22 is then moved to the positions where each of the detectors 11 are placed in operation singly and the procedure may then be repeated and the article may be explored entirely sector by sector. The detectors may alternatively be scintillation counters in which case two groups may be used, one group monitoring α radiation and the other monitoring # and y-radiation.
