| Abstract:: |
| Objective To validate and discuss the time response correction formula for four types of dosimeters (6150AD6+6150AD-b, FH40G+FHZ672E-10, 451P ionization chamber and AT1123). Methods The ambient dose equivalent rates shown by survey meters were recorded separately when X-ray emission time was 500, 200, 100 and 50 ms.The corrected values were obtained by the formula of circuit having a capacitance C and asistance R in series. Results Therewas no correlation between the value measured by AT1123 dosimeter and the time of irradiation.The values by other three kinds of dosimeters obviously varied with the time of irradiation. Conclusions It is not required to make the time response correction for the measured value of AT1123 dosemeter, whereas the values measured by the other three dosimeters could be corrected by the time response correction formula. |
