Abstract
Abstract A device for measuring radioactive radiation in a liquid, comprising a measuring chamber with inlet and outlet for the liquid, and a photomultiplicator connected to the measuring chamber for the purpose of measuring the Cerenkov radiation generated in the liquid in which the walls of the measuring chamber are provided with a relatively thick layer of an optically transparent material, resulting in the energy resolution of the device being increased.

A Cerenkov detector for detecting the presence of radiations of fission products in the coolant liquid of a nuclear reactor, comprising a pressure chamber, means for supplying and withdrawing coolant liquid to the pressure chamber, a layer of an optically transparent solid material having a thickness of 6- 15 mm. and lining the pressure chamber, a white reflector layer between the optically transparent solid material and the wall of the pressure chamber, a window in the pressure chamber, and a photomultiplier connected to said window for measuring the Cerenkov radiation generated by such fission products in the coolant liquid as emit beta radiation of an energy of more than 4 Mev.
