What are some Pyroelectricity Detectors technical report?
Cock Crusher My name for everything
The radioactive isotope that the source (usually americium) given off in the detector decays so rapidly that by the time it reaches the outer edge of the sensor itself it is safe. There was a story about 15 years ago where David Hahn had collected on the order of hundreds of smoke detectors and gathered up the radioactive material to try to make a breeder reactor in a shed in his mothers backyard, there was enough there that it irradiated the shed he was using to the point where it had to be dismantled and classified as low-level radioactive waste. That just goes to show what happens when some people have too much free time on their hands.
