Americium-241 is an α-emitter with a weak γ-ray byproduct. Safely handling americium-241 requires knowing and following proper safety precautions, as without them it would be extremely dangerous. Its specific gamma dose constant is 3.14 × 10 −1 mR/hr/mCi or 8.48 × 10 −5 mSv/hr/MBq at 1 metre (3 ft 3 in). [27]
Americium-241 is the most common isotope of americium in nuclear waste. [8] It is the isotope used in an americium smoke detector based on an ionization chamber . It is a potential fuel for long-lifetime radioisotope thermoelectric generators .
The most important isotopes of these elements in spent nuclear fuel are neptunium-237, americium-241, americium-243, curium-242 through -248, and californium-249 through -252. Plutonium and the minor actinides will be responsible for the bulk of the radiotoxicity and heat generation of spent nuclear fuel in the long term (300 to 20,000 years in ...
The amount of elemental americium-241 in ionization smoke detectors is small enough to be exempt from the regulations applied to larger deployments. A smoke detector contains about 37 kBq (1,000 nCi) of radioactive element americium-241 (241 Am), corresponding to about 0.3 μg of the isotope.

Public health campaigns and programs outlining the dangers of smoking aren’t really aimed at older adults, says Rafael Meza, an integrative oncologist at the BC Cancer Research Institute in ...
Americium-241 has been used as a source of low energy gamma photons, it has been used in some applications such as portable X-ray fluorescence equipment and common household ionizing smoke detectors. Americium-241 is produced from 239
