TROUBLESHOOTING 
 
 

 

Symptom: radiation count rate greater than zero even when 
no radiation present after contacting radioactive tissue 

Resolution: decontaminate probe tip of radioactive material 
using sterile process

 

 

 

Symptom: spurious radiation counts in conjunction with 
energizing electrocautery device or other radio-frequency 
emitter 

Resolution: move electrocautery device cable or other radio- 
frequency emitter away from probe 

 

 

 

Symptom: spurious radiation counts not associated with 
radiation contamination or electrocautery device or other 
radio-frequency emitter 

Resolution: replace probe

 

 

 

Symptom: insufficient or complete lack of radiation counts 
when locating the probe over a known source of high 
radioactivity 

Resolution: replace probe

 

 

 

Symptom: new probe 

or probe that hasn’t expired won’t 

connect with a UFU. 

Resolution: turn the UFU off then back on 

–

 the UFU must be 

turned off prior to connecting to a new probe.
