To prevent the recurrence of irradiation accidents, monitor-unit (MU) verification that is independent of the MU values calculated using the radiation treatment planning system (RTPS) is required. In this study, we investigated whether independent verification of MU values is being conducted in medical settings and examined the types and methods used. Our results indicate that 93.8% of facilities conduct independent MU verification. The methods used vary according to the facility: 30.4% conduct actual measurements, 18.6% use MS-Excel calculation sheets, 16.7% use specialized commercially-available software, 14.7% use spreadsheets 13.7% use calculators, and 5.9% use other methods. In this study, we were able to formulate basic data that can be used for information-sharing between facilities.
