CALIBRATION RECORDS; TELETHERAPY, REMOTE AFTERLOADER, AND GAMMA STEREOTACTIC RADIOSURGERY UNITS

A licensee must maintain a record of the teletherapy unit, remote afterloader unit, and gamma stereotactic radiosurgery unit full calibrations required under parts 4731.4469 to 4731.4471 for three years. The record must include: A. the date of the calibration; B. the unit manufacturer's name; C. the model number and serial number of the teletherapy, remote afterloader, and gamma stereotactic radiosurgery unit; D. the model number, serial number, and identity of the source; E. the model number, serial number, and identity of the source instruments used to calibrate the units; F. the results and an assessment of the full calibrations; G. the results of the autoradiograph required for low dose-rate remote afterloader units; and H. the signature of the authorized medical physicist who performed the full calibration.
