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]
The critical masses of the two readily available isotopes, 241 Am and 243 Am, are relatively high – 57.6 to 75.6 kg for 241 Am and 209 kg for 243 Am. [97] Scarcity and high price yet hinder application of americium as a nuclear fuel in nuclear reactors.

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 .
After removal of fuel from reactor, decay will predominate for shorter-lived isotopes such as 238 Pu, 241 Pu, 242–244 Cm; but 245–248 Cm are all long-lived. Fertile material is a material that, although not fissile itself, can be converted into a fissile material by neutron absorption .
Americium hydroxide is a pink solid [15] which is sparingly soluble in water. [16] Due to self-irradiation, the crystal structure of 241 Am(OH) 3 decomposes within 4 to 6 months (241 Am has a half-life of 432.2 years); for 244 Cm(OH) 3 the same process takes less than a day (244 Cm has a half-life of 18.11 years).
