Abstract From the Canadian patent
A radiation detector for dirty bomb and lost radioactive source detection applications, is enclosed in a small pager-style housing made of impact resistant ABS plastic and epoxy, binder composite which is relatively transparent to alpha beta, gamma, fast , neutron, and, x-ray radiation while also being optically opaque and providing a protective enclosure for the, radiation detector components disposed inside the housing. The detector combines indirect, radiation detection using a scintillator and photodiode and direct radiation detection by, placing the photodiode and a high gain amplifier in the path of radiation. Semiconductors in, these components generate an electrical signal …

Why it's free to use
- Filed December 30, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 30, 2023.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
