| 内容記述 | The purpose of this study was to investigate the effect and address the suitable electron energy in cross-calibration with or without an external monitor chamber. First, using the two linear accelerators, the calibration factor (N_(〖D,w,Q〗_cross)^field) and absorbed dose to water calibration factor (N_(D,w)) values are compared with or without an external monitor chamber using cross-calibration in standard dosimetry 12. Next, the N_(〖D,w,Q〗_corss)^field uses five different energies (12, 15, 16, 18, and 20 MeV) for its cross-calibration. Then, 6 MeV electron absorbed dose at depth of the dose maximum (D (dmax)) is calculated. We compared to D (dmax) for the calibration factor (N_(D,w) (Co)) given by 60Co gamma radiation. The N_(〖D,w,Q〗_corss)^field is almost equal in both using and not using an external monitor chamber, the difference value of N_(〖D,w,Q〗_corss)^field was only 0.01%. Between both D (dmax) using calibration factors N_(〖D,w,Q〗_corss)^field and N_(D,w) (Co) is a significant difference (P < 0.001). Moreover, there is also a significant difference between D (dmax) using calibration factor obtained from 20 MeV and each 12 MeV, 15 MeV (P < 0.05). These results demonstrate that there is no significant change with or without the external monitor chamber. Furthermore, the electron energy most suitable for obtaining calibration factors N_(〖D,w,Q〗_corss)^field in cross-calibration is found to be 20 MeV, and the absorbed dose is almost the same value at 12, 15, 16, and 18 MeV． | |||||
