432 a Americium has several isotopes and
241
Am is a ra-
dioactive isotope. It is a typical companion found in var-
ious plutonium nuclide compositions and therefore it is
regarded as threat. This nuclide can also be found in
components of smoke detectors, where a small ameri-
cium source acts as an ionizer.

Innocent Several nuclides emit �+ particles. These particles may
recombine with negative particles in the detector ma-
terial, typically depositing a photo energy of 511 keV.
Some of these isotopes are used for positron emission
tomography (PET).
The
radEAGLET displays the identification result �+
when confronted with such a source because all
sources share the 511 keV line and cannot be differ-
entiated further (except
22
Na).
