Hazards and Risks
Hazards and risks associated with americium: americium does not occur naturally in the biosphere and so normally never presents a risk. In practice, americium is only found in any quantity inside controlled environments within research laboratories and nuclear facilities. In very, very small quantities, its α-radiation does find practical use in small smoke detectors. All such instruments are clearly labelled as containing radioisotopes.
