The invention provides a gamma dose rate probe adopting a Kalman filter. The gamma dose rate probe comprises a nuclear radiation detector, a signal forming circuit, an MCU and an external circuit, the MCU adopts a counter to receive the primary signal, adopts a plurality of Kalman filters to carry out data processing on the received pulse signal data, and realizes burr of the primary signal by adjusting the process noise variance and observation noise variance of the Kalman filters. The device has the following advantages: (1) the stability of output data is improved, and a Kalman filter with proper parameters is automatically selected for filtering according to the fluctuation degree of the data; and outputting the response time of the data, and realizing the switching or parameter correction of the Kalman filter through the discrimination condition of the data discriminator, thereby controlling the response time of the data. And (2) according to the set parameters, the stability and response time of the dat
