= Am-241 =

Can be found in ionization smoke detectors. Modern units typically contain 1 uCi max. However, some older models contain much more such as the Pyrotronics F3/5A (80 uCi)

"each detector contains only a tiny amount of americium-241, which is sealed in a gold matrix “to make sure that corrosion does not break it down and release it.”" ([http://harpers.org/archive/1998/11/the-radioactive-boy-scout/4/ source])

http://large.stanford.edu/courses/2011/ph241/eason1/
* "a typical modern detector contains about 1.0 microcurie of the radioactive element americium, which is equivalent to 37 kilobecquerel (37,000 decays per second), or 0.33 micrograms of americium oxide (AmO2)"
* "The average quantity of americium per detector has decreased from 3 microcurie in 1978."

* Pu/Am chemistry
* Patent: 637,484: separating Pu/U
* Am specific chemistry starts about column 7

Commercial AmBe sources for oil exploration (neutrons measure water content)

= H-2 (Deuterium) =

Deuterium lamps contain a very small amount

= H-3 (Tritium) =

Powerless exit signs can contain several Ci (yes, whole number) to make them glow for a few years

= Ra-226 =

== Smoke detector ==

Smoke detectors can have a small amount. IIRC mine had 0.05 uCi (0.5?)

== Watch ==

"The estimated dose from a watch containing 4.5 uCi of radium, a very large amount, would be 310 mrem per year to the gonads."

[Radioluminescent Paint] indicates watches can have up to 5 uCi with averages much lower (0.36 uCi peak in the 60's)

Most commonly in some russian smoke detectors. Less common includes the RTGs and specialty radiation detectors
