Symbol: Am. A man-made metallic element whose isotopes Am-237 through Am-246 are all radioactive. Americium must be handled with great care to avoid personal contamination. Trace quantities of americium are widely used in smoke detectors. It is also used in bone mineral analysis and as a radiation source for radiotherapy. Americium was discovered i [..]

An artificial radioactive element with atomic number 95 (symbol Am), produced in nuclear explosions and reactors; emits alpha particles.

a silvery metal; it is a man-made element whose isotopes Am-237 through Am-246 are radioactive. Am-241 is formed spontaneously by the beta decay of plutonium-241. Trace quantities of americium are wid [..]
