When might the treatment timer of a 60Co machine require correction?

The treatment timer of a 60Co machine might require correction if it reads less or more compared to a calibrated electronic timer. This criterion is crucial because an accurate timer is essential for the delivery of precise radiation doses to patients. A calibrated electronic timer serves as a reliable standard for comparison and ensures that the treatment delivered is both safe and effective.

Discrepancies between the actual timer reading and the calibrated electronic timer indicate that the treatment machine may not be functioning as intended. Such inconsistencies could result in either underdosing or overdosing, which can have significant implications for patient safety and treatment outcomes. Therefore, routine checks against a calibrated timer are vital for maintaining the accuracy and reliability of radiation therapy equipment.

In clinical practice, adherence to these calibration protocols is central to the goals of medical dosimetry. Regular monitoring allows for timely adjustments and corrections, ensuring that any operational issues are addressed before they can affect patient treatment.
