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). Medicine. Americium-241 gamma rays has been used to provide passive diagnosis of thyroid function. Its common isotopes are 241 Am and 243 Am. The back-end of the nuclear fuel cycle, mostly spent fuel rods, contains fission products that emit beta and gamma radiation, and actinides that emit alpha particles, such as uranium-234 (half-life 245 thousand years), neptunium-237 (2.144 million years), plutonium-238 (87.7 years) and americium-241 (432 years), and even sometimes some neutron Americium-241 is used in smoke detectors, but its radiation poses little threat. This isotope costs around $1500 per gram but this is enough americium for more than five thousand detectors.

What feature of the radioisotope americium-241 would be most helpful for the smoke detector to work? Question: Part C Americium-241 Is Used In Some Smoke Detectors. It Is An Alpha Emitter With A Half-life Of 432 Years. How Long Will It Take In Years For 36.0% Of An Am-241 Sample To Decay?

A Geiger counter, a device for counting alpha radiation, is placed below the conveyor belt. 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). Americium-241 gamma rays were also used to provide passive diagnosis of thyroid function.
