Question
Americium-241 is the most common isotope of americium. It is commonly found in ionization type
smoke detectors and is a potential fuel for long-lifetime radioisotope thermoelectric generators. It
decays to Neptunium-237 by alpha emission. How much energy (in joules) is given off by the decay?
(235 Am = 241.056 amu; 93Np 237.048 amu; He = 4.0026 amu; 1 amu = 1.661x10-24 g.)
