目的方便介入放射工作者介入手术操作,同时真实记录介入工作者受照剂量。方法对放射介入操作人员手部剂量测量时,将剂量计佩戴于手指和手腕情况下的剂量测量结果进行了比较。结果手腕剂量计测得的剂量相对于手指部位的剂量计测得的剂量的偏差为-31%～37.5%之间。结论实验结果表明,利用佩戴于腕部的剂量计测读的值评估操作人员的手部剂量是可行的。
Objective To facilitate interventional radiosurgery interventional operation, while real records of intervention workers exposure dose. Methods The dosimetry results of dosimeters worn on the fingers and wrists were compared with those of radiotherapy interventional operators. Results The dosimeter measured by the wrist dosimeter had a deviation from the dose measured by the dosimeter at the finger site of -31% -37.5%. Conclusion The experimental results show that it is feasible to evaluate the hand dosage of the operator by using the reading value of the dosimeter worn on the wrist.
