Abstract In the detection of Radon gas it is common for the radon sample to be admitted to a dark chamber the sides of which are coated with a 'phosphor' (silver activated zinc sulphide or equivalent). the resultant light flashes(caused by the alpha emanation striking the 'phosphor') are then counted by a highly sensitive light detector such as a photo multiplier tube. The auxiliary circuitry for the photo multiplier tube is expensive, there is a problem of the phosphor being contaminated by build up of Radon daughters and a problem of light contamination in changing chambers in the field . In this invention, a less sensitive but economical solid state optical sensor is used and an increase in sensitivity obtained by depositing the 'phosphor' directly upon the optical detector. This may then be sealed with a thin metallic deposit that is opaque to light but semi transparent to alpha emanation. The reduced sensit- ivity due to reduced surface area may be compensated for by longer periods of observation.
