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 also suitable for calibration of gamma-ray spectrometers in the low-energy range, since its spectrum consists of nearly a single peak and negligible Compton continuum (at least three orders of magnitude lower intensity). [115] Americium-241 gamma rays were also used to provide passive diagnosis of thyroid function.
Americium-243 has a mass of 243.06138 g/mol and a half-life of 7,370 years, the longest lasting of all americium isotopes. It is formed in the nuclear fuel cycle by neutron capture on plutonium-242 followed by beta decay . [ 15 ]
Americium hydroxide is a pink solid [1] which is sparingly soluble in water. [2]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 one day (244 Cm has a half-life of 18.11 years).

Americium dioxide is the most widely used americium compound in ionising smoke detectors. The dioxide form is insoluble in water, making it relatively safe to handle in production. In the late 2010s, americium dioxide has been of interest to ESA as power source for radioisotope thermoelectric generators (RTGs) for deep space exploration ...
