The Comparison of the KAPM Dosimetric Protocol (1990) with the TG-21 and Cλ / CE (ICRU-21 and SCRAD protocol) method is studied. The therapetutic range of radiation (photon 4MV-15MV and electron 6MeV-20MeV)and three kinds of the chambers were used in the water phantom. The Results from TG-21 and KAPM Protocol did not show much differences (less than 1%) throughout the whole energy range; ND from KAPM protocol and Ngas from TG-21 showed 0.2% deviation mainly from W/e difference between two protocols. But the results from KAPM protocol (1990) and those from Cλ / CE Method showed –1.9±0.6%(KAPM protocol is higher) deviation for photom beam and ＋3.3±1% (KAPM protocol is lower) deviation for electron beams.
