EPA Facts about Radium

Isotopes of radium decay to form radioactive isotopes of radon gas. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. The half lives are 3.5 days for radium-224, 1,600 years for radium-226, and 6.7 years for radium-228, the most common isotopes of radium, after

Jun 29, 2010 · 14 Ionisation smoke detectors contain a small amount of the radioactive isotope americium. 241Am is an α-emitter. It has a half-life of 432 years, and the activity from the source in a new smoke detector is about 3.5 × 104 Bq. (a) Explain why the radiation produced by a smoke detector does not pose a health hazard. (1)
