Abstract：The applications of ionizing radiation metrology in nuclear power plant are reviewed, such as the reactor control nuclear instrument, radiation protection instrument, environmental monitoring instrument, especially for the manufacture of standard source for gaseous effluent, the calibration of whole body counter measurement system, the monitoring of weakly penetrating radiation.The traceability needs of the monitoring for high energy of 6.13 MeV γ-ray dose, the calibration for high-dose range γ-ray instrument, the monitoring of reactor neutron flux and the distribution of neutron dose in staff channels are also described.
