GRIMM - Model 5522-A -Aerosol Neutralizer
The GRIMM 5522-A aerosol neutralizer is based on the radioactive decay of Am-241 (nominal activity 3.7 MBq), that produces a bipolar ionic atmosphere by α radiation. Irregularly charged particles (from ambient or lab generated) are brought into a defined stationary-state charge distribution, regardless of their initial charging state. Aerosol neutralizers based on radioactive sources are nearly maintenance free and well proven.
