The Central Electrode Correction Factor that corrects the effect due to the electrode being made of non-air material is base on the data from the depth of 5cm in water. But TG-51 protocol proposes the reference depth of 10cm in water. The purpose of this research is to check the alteration of Central Electrode Correction Factor due to the change of reference depth from 5cm to 10cm in water using Monte Carlo Computing Methods. The results showed that the change of Central Electrode Correction Factor is ignorable in the statistical errors of 2% for two different depth, 5cm and 10cm.
