Thorium lantern mantles
Thorium lantern mantles. The thorium makes a lantern's light burn whiter, and this makes a very nice
alpha, beta, and gamma demonstration source. Not all lantern mantles contain thorium.

Cesium
Cesium-137 check sources are very common. Most are exempt from regulation as long as they are
intact, accounted for, and properly labeled.

Smoke detectors contain americium
Smoke detectors contain americium-241 sources, that are most often exempt from regulation UNLESS
they are removed from the detector housing. Old industrial smoke detectors may contain radium sources,
none of which are exempt.
