A sample of Americium in the form of a gold coated Am-241 foil mast mounted source.  This contains about 40uCi total of Am-241 compared to a standard smoke detector which is only 10uCi.  This also contains Np because about 15uCi have decayed into Np-237 through the natural decay process.  A much better alternative to a small standard smoke detector source for an Am sample!
