According to CFR regulations, the instrumentation required for the dose calibrator must be calibrated based on which section?

The correct choice associated with calibrating dose calibrators according to CFR regulations is indeed 10 CFR 35.60. This section specifically outlines the requirements for the calibration of instruments used in the measurement of therapeutic and diagnostic radioactive materials.

Calibration is essential to ensure accurate dosage measurements for radioactive materials administered to patients, which is crucial for both safety and effectiveness in nuclear medicine practices. This regulation details the necessary benchmarks and protocols healthcare facilities must follow to maintain compliance and ensure that their equipment delivers accurate readings.

While other sections of 10 CFR 35 address different regulatory aspects related to radioactive materials, 10 CFR 35.60 is the one that directly pertains to the calibration of dose calibrators, making it the relevant choice in this context.
