Error
Possible cause and remedy
Pulse rate too low at
empty vessel
• Radiation source switched off
Switch on source at the source container
• Incorrect alignment of radiation beam
Realign beam
• Buildup in the vessel
Clean vessel or
Recalibrate (if buildup is stable)
• Fittings in the vessel have not been considered in the activity calculation
Recalculate activity and change source accordingly, if required
• Pressure in the vessel has not been considered in the activity calculation
Recalculate activity and change source accordingly, if required
• No radiation source in the source container
Load source capsule in the container
• Source too weak
Use source with higher activity
Pulse rate to high at
empty vessel
• Activity too high
Attenuate radiation, e.g. by mounting a steel plate in front of the source
container; or exchange source
• External radiation source (e.g. by gammagraphy)
Shield off if possible; repeat calibration without external radiation source
Pulse rate too high at full
vessel
• External radiation source (e.g. by gammagraphy)
Shield off if possible; repeat calibration without external radiation source
