Abstract
Disturbances caused by static electricity in liquid scintillation counting are eliminated by an ionizing device. A liquid scintillation counter in a measurement chamber surrounded by a radiation protective device measures nuclear fissions occurring in a sample bottle moved into the measurement chamber along a predetermined path. The ionizing device ionizes the air by producing positive and negative ions in the path followed by the sample bottle into the measurement chamber. Ions produced by the ionizing device on the sample bottle before the bottle enters the chamber neutralize any electrostatic charge on the bottle.
