Abstract

1509189 Radio-active sources ANALYTICAL INSTRUMENTS Ltd 8 Aug 1975 [13 July 1974] 31141/74 Heading G6R A beta particle-emitting radio-active source for use in an ionization detector comprises a radio-active tritiated carrier coated with a thin layer of a low density material -which is non- radio-active and is not affected by radiation from a radio-active source. The carrier may be a layer of titanium supported on a copper or stainless steel foil. The coating material may be aluminium of thickness less than 1 micron. In the detector shown, the radio-active source 6 is in the form of a cylindrical sleeve arranged between electrodes 1, 2, gas being introduced at 4 and leaving at 5. The coating reduces the energy of the beta particles emitted and also reduces tritium loss at elevated temperature.
