Application of semiconductor detectors in gamma knife's verification

According to the small size,high sensitivity and non-directional characteristics of the semiconductor detector,a kind of semiconductor detector for measuring the dose rate of gamma knife's focus was developed.Then a semiconductor detector's model for gamma ray measurement was built,and the measurement calculation method of the semiconductor detector's model was given.The experimental tests show that the semiconductor detector developed was suitable for the measurement and verification of the gamma knife's focus dose rate at small gamma radiation field.
