Ionization-type smoke detectors use the emissions from americium-241 to create a small electrical current in the detector, which sends out an alarm when smoke that enters the detector causes the current to decrease. The half-life of Am-241 is 432 years. a. Explain why Am-241 spontaneously emits an alpha particle.
