Instrument maintenance

• Distinguish the fault into operational or functional types.

• Inventory• Physical damage• Interconnecting cables, Timer, Power supply

need to be checked periodically

Testing and Calibration

• Energy calibration test• Energy linearity test• Sensitivity test • Timer test

Quality ControlNo. Test Function of the equipment Reference Freq. of Routine

1. Scalar/timer and rate meter No Quarterly

2. Energy Calibration No Weekly

3. Counting Precision (Statistics) No Quarterly

4. Linearity of Activity Response No Half yearly

5. Response of Recorder No Half yearly

6. Analyser peak setting Every time a radionuclide is changed

7. Background counts in counting channel

Every day
