For a classical radioactive bipolar charger, charging probabilities do not depend on instrument parameters and the charger is considered as reference. The theoretical charging probabilities are well known and the unwanted contribution of multiple charged particles is low. Consequently, the calculated size distributions feature highest accuracy. A neutralizer using Am241 needs almost no maintenance and features a lifetime of many years.
