  • Detector for aiborne alpha partice radiation
    Patent number: 7745799
    Abstract: In the field of protection from ionising alpha particle radiation there is a need for a low cost, reliable, maintenance free, and self-contained detector that can monitor continuously over a plurality of time periods the levels of airborne alpha particle radiation. The detector operates by measuring the charge created by alpha particle decay between electrodes in an enclosure. Detectors may be linked together to monitor several parts of a building or a large area for applications such as civil emergencies and earthquake warning.
