Annual Tests
The Accuracy Test should be performed semi-annually (at least annually) to ensure the
continued accuracy of the instrument.
Accuracy Test
The accuracy of the instrument should be verified using appropriate Reference
Standard Sources such as Cs137, Co57 and Co60. The activity of these Standard
Sources should be sufficient to obtain precise measurements at approximately those
levels normally encountered.
The activity determined by the calibrator should coincide with the activity of the
certified Reference Standard Source to within ±5%.
Should the activity reading for Co60 and/or Co57 be confirmed to be inaccurate by
more than ±5%, the instrument should be repaired. Do not alter the system
calibrations of the instrument unless the cause of the disagreement is found.
If the calibrator is used to determine a therapeutic dose for a patient, the accuracy of
the measurement should be tested by all means possible.
