Abstract
In a liquid scintillation counter a standard radioactive source is supported within the tubular bore of a flexible coil spring conveyor. Spacer elements within the coil spring retain the source at a predetermined axial position along the spring. The coil spring is disposed in sliding engagement along a conveyor guideway. A drive roller drivingly engages the spring for conveying the source along the guideway between an operating position adjacent the counting chamber and a remote shielded position.
