| Abstract:: |
| This paper describes an investigation on the quality of the primary beam of diagnostic X-rays and the scattered X-rays at 90°and at a distance of 1m from the centml ray of the primary beam.According to the result of this investigation and the characteristics of calcium sulphate and lithium fluoride thermolumineseence dosimeter.An energy response modification method for using uncompensated calcium sulphate as a perseal monitor for medical diagnostic X-ray workers was proposed.An energy fesponse modification factor,which is about 0.13.Was determined by a simulating experiment.This method has been used in personal dose monitoring sevice in Beijing.The data showed the feasibility of this method. |
