| Abstract: | In order to obtain neutron spectrum quickly and measure the dose rate of neutron radiation field accurately, an Bonner sphere spectrometer was designed. The system can measure neutron spectrum online and display neutron dose rate in real time. The spectrometer was verified in a Am-Be reference radiation field. The result was in good agreement with the standard spectrum, and the deviation between the measured dose rate and the true value after conversion was less than ±7%. |
