The amount of manganese in waste water can be esti-
mated by analyzing this isotope. Therefore, it is a reli-
able predictor for heavy metal pollution in the water of
mining activities.

Na features a high energetic line beneath its �+ emis-
sion and is well-suited to investigate pipeline leakage or
welding quality.
Some further applications are found in medicine.
The identification result for this isotope will display
Na22 and additionally �+Na22 because the �+ emission
is a natural part of the isotopes radiation profile.

Neptunium is used to produce
238
Pu. It is considered to
be a major SNM threat, as are uranium and plutonium.

Plutonium is a severely dangerous material. It is ex-
tremely poisonous and poses a deadly risk for humans.
The radEAGLE distinguishes four mixtures of
239
Pu
with
240
Pu. The abbreviation RGPu stands for reactor-
grade plutonium (yielding a higher amount of
240
Pu in
the composition). Weapons-grade plutonium (WGPu)
has a higher amount of
239
Pu and a lower amount of
240
Pu. The denotion “HS” marks a source with heavy
shielding where only few or none of the lower energy
gammas of plutonium may be found in the spectrum.
It is common for both reactor-grade or weapon-grade
plutonium to be accompanied by an ID of
241
Am.
