The Protection Measure Research into the Medical Diagnostic X-ray of 'Peace Ark' Hospital Ship

摘要

In order to understand the radiology injury to the working personnel and subjects it is detected the dermal dose of subjects receiving radiology diagnosis on the "Peace Ark" Hospital Ship, to statistically calculate the average dose volume and weighted dose equivalent of each X-ray diagnosis posed on the subjects, and carry out comparison analysis for the risk degree of subjects of different ages and genders. Results demonstrated, for each diagnosis, the subjects to radiology diagnosis would all have different radiology dose on skin and other corresponding organs; with the increase of age, the radiology risk degree of subjects would decrease gradually, the male subjects have different risk degree in different radiology dose and risk degree compared with female subjects in different tissues and organs. It is suggested that radiology diagnosis working personnel and subjects should be careful to apply radiology diagnosis, to justify the radiology diagnosis, at the same time, reduce the exposure, to realize the optimization of radiology protection.
