ABSTRACT
Objective:According to the technical standard of ISO and current regulations in China, the X/γ standard calibration quality for the finger-ring dosimeter irradiation was established in Beijing SSDL, it can ensure the traceability of surveillance data within countrywide.Methods: Air kerma-rate was determined in the X-ray beams,137Cs and60Co by a standard dosimeter, combined transfer coefficientHp(0.07) provided by standards, and confirmed condition of X/γ standard calibration quality for the finger-ring dosimeter irradiation. Using finger-ring TLD dosimeter verified the radiation beam qualities Hp on the ISO finger-phantom.Results: The linearity and energy response of the TLD dosimeter met ISO and national standard in Beijing SSDL.Conclusion: The X/γ standard radiation field can be used for the calibration of finger-ring dosimeter standard curves and experiment of research, and can further promote the comparability and reliability of the surveillance data.
