摘要：
Two methods were used to improve procedures of fission track dating: (1) to measure absolute neutron fluence using SRM 962 uranium dosimeter glass calibrated against Co activition foils; (2) to determine zeta calibration constant. The calibration factor B was measured from 12 irradiations to be (5.79 +/- 0.29) x 10(9) neutron/track. The seta calibration constant determined against SRM 962 uranium dosimeter glass is 327.5 +/- 7.8 (2sigma). In this persentation, some results on fission track dating calibration using uranium dosimeter glass and age standards are described.
