ABSTRACT
Objective:
To carry out comparative study on energy respond characteristics of 4 kinds of medical diagnostic X-ray dosimeters that included general new imported equipment and domestic equipment.Methods:
In the standard radiation field of secondary standard dosimetry laboratory(SSDL)of IAEA,substitution method was adopted to complete contrast measurement of 10 kinds of X-ray diagnosis radiations which voltage were 60-150 kV,tube current were 10 mA and 2.5 mmAl was used as filterable addition.Results:
The results of energy respond performances of domestic RD-98 diagnosis dosimeter and imported dosimeter indicated that all of these responses of different energy to dose were within ±5%when X-ray range was 6-150 kV.Conclusion:
The energy response characteristics of 4 kinds of new diagnosis X-ray dosimeter were better,and the response of different energy to dose conforms to the requirement of IEC in diagnosis dosimeters of semiconductor detector and air ionization chamber.
