By Shawna Miller & Crystal Thomas
Americium (chemical symbol Am) is a man-made radioactive metal, with Atomic Number 95.
A silvery metal; whose isotopes americium-237 through -246 are all radioactive. Americium-241 is formed spontaneously by the beta decay of plutonium-241.
A typical detector contains 0.9 micro-curie of americum-241
