6A very small quantity of Americium-241 (AM-241) is a vital ingredient in <a device>.

Americium-241 emits alpha particles and low energy gamma rays. The alpha particles emitted by the Am-241 collide with the oxygen and nitrogen in air in the ionisation chamber to produce charged particles (ions). 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. When _____ enters the space between the electrodes, the ____ particles attach to the charged ions, neutralizing them. This causes the number of ions present – and therefore the electric current – to fall, thus successfully <doing something>.

What is being described above ? ( Both blanks are the same)
