A low-level electric voltage applied across the chamber is used to collect these ions, causing a steady, small electric current to flow between two electrodes. 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.

Genom en linjär implosion bildas en sfär, och samtidigt övergår det till α fas.

A low-level electric voltage applied across the chamber is used to collect these ions, causing a steady, small electric current to flow between two electrodes. 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. 241Am (Americium) Americium is a man made radioactive isotope, and is commonly found in smoke detectors.
