According to the recommendations of ISO4037-1:1996, we have established the filtered x-ray reference radiation of low air kerma rate series (10 reference radiations), narrow spectrum series (13 reference radiations ), wide spectrum series (7 reference radiations) and high air kerma rate series (8 reference radiations) in CIRP. The relevant calibration facilities, such as ISO water phantom, are also built for calibration practice. An Yxlon MG325 is used as x-ray generator. Totally 38 reference radiations are produced with tube voltage range from 15 kV to 300 kV. The characteristics, such as HVL (half value layer), for these reference radiations are investigated. They are well consistent with the recommendations of ISO and can be used for the calibration of dose & doserate meters for radiation protection purpose. |
