Abstract: 1,187,987. Cerenkov radiation detector. ATOMENERGI A.B. June 5, 1967 [June 16, 1966], No. 25938/67. Heading G1A. Radio-active materials present in a liquid are measured by detecting the Cerenkov radiation they produce in the liquid and from layers of optically-transparent material lining the walls of the through-flow chamber. #-emitting fission products in the coolant water of a nuclear reactor, present due to leakage from damaged fuel elements, are detected by the apparatus shown. Water flows through conduits 5 into chamber 4, having white reflecting coatings 7 of epoxy resin, and out through conduits 6. Cerenkov radiation produced in the water itself passes through a quartz glass window 10 and a glass disc 21, and is detected in photomultiplier 13. The (3-radiation from the fission products also produce Cerenkov radiation from the walls 8, 9, which are preferably of a transparent plastics material, or of glass or quartz; and also from the window 10. A further wall, similar to that 9, can be inserted in front of window 10. The use of the transparent walls increases the production of Cerenkov radiation by high energy #-particles (from the fission products) but has little effect on Cerenkov production by #-radiation of lower energies which is generated by corrosion and unstable isotopes formed by irradiation of the water when it was in the reactor. Thus the detector energy resolution is improved by the use of these walls.
