Am-241 found in the environment is in the form of microscopic dust. When released into air, americium deposits particles in the soil and water. Small particles in air can travel far from the release site. In water, americium will stick to particles in the water or to the sediment at the bottom.

the Faroe-Bank Channel, which thereby serves as an important source for the Plutonium isotopes and 241Am were studied in seawater and sediment from of both carbon fixation (50-70%) and chlorophyll-alpha (80-90%), nanoplankton

A survey meter equipped with a alpha scintillation probe is suitable for detection of the Whole Body dosimeter: Required, unless a sealed source completely In demonstrations conducted in the laboratory, a sealed alpha source (Am‑241) is to detect the contaminant Am-241 and infer the accompanying plutonium.

This is a typical gamma spectrum from Americium, as you can see, the tall peak at 59.6 KeV is very obvious and over powers everything else, it also has a gamma at 26.3KeV which is sometimes visible to the left of the tall peak. Americium-241 isotope is used frequently for investigations of luminescent detectors and materials as a source of alpha particles, but it emits also gamma-rays (59.4 keV), what may have influence on the measured signal.
