Based on the structure and detecting principle of vacuum diode detector, the γ-ray sensitivity is obtained by Monte Carlo calculation and contrasted by the experiment resuh. The result from calculation is contrasted by that form experiment, and both are according with each other within measurement uncer-tainty. Verified by experiment result, the Monte Carlo model can also calculate γ-ray energy response of vacuum diode detector. The study work offers an economical and practical method to obtain γ-ray sensi-tivity and energy response of vacuum diode detector.
