Abstract

The invention discloses a method for measuring neutron, gamma energy spectrum and dosage in a nuclear power station. The method comprises the following steps: 1 ) the neutron and gamma rays are inputinto a neutron detection system to output a signal A, and the gamma rays are input into a gamma detection system to output a signal B; 2) the signal A and the signal B are input into a digital signalprocessing circuit to be subjected to operation processing to obtain the neutron, gamma energy spectrum and dosage, wherein the digital signal processing circuit takes a field-programmable gate arraychip as a core chip. Compared with the prior art, the method for measuring neutron, gamma energy spectrum and dosage in the nuclear power station disclosed by the invention has the advantages that thesimulations measurement of the neutron, gamma energy spectrum and dosage can be realized based on the field-programmable gate array technology. In addition, the invention further discloses a system for measuring the neutron, gamma energy spectrum and dosage in nuclear power station.
