Americium-241 is used in some smoke detectors It is an alpha emitter with a half-life of 432 How long will it take in years for 31.0 of an Am-241 sample to decay?
288
Why is americium-241 ideal to use in gauges?
Americium 241 is an artificial isotope with a long half life - 432,2 years - and a gamma ray emitter. Being a strong gamma emitter it can be used for gamma radiography of materials and for thickness gauges.
Why is curium 242 not suitable for use in smoke detectors?
It is radioactive. ------------------------------- Incorrect answer: americium-241, the usual isotope in smoke detectors is more radioactive.
