距离防护

在手术时，备用人员在铅屏风后面等候或离诊断床稍远一些，将时间防护、屏蔽防护和距离防护进行合理利用。

When operation going along , someone of standby is waiting for behind lead screen , we make use of time protection , shield protection and distance protection correctly .

结论介入操作中应从屏蔽防护、距离防护和缩短照射时间进行防护，减少操作者的辐射危害保障健康。

Conclusion The X ray radiation protection should be carried out from shielding protection , distance protection and radiation time reducing ; That can reduce the damage of radiation to keep the operator healthy .

因此，应该分别计算卫生防护距离和大气环境防护距离，结合项目的实际情况确定最终的防护距离。

So it was should to calculate both of them , then combine with the actual situation and the ultimate of the project to determine the final protection zone .

研究结果表明：（1）卫生防护距离和大气环境防护距离在计算原理、参数设置、取值范围、结果取级等方面存在差异，但是二者设置的目的都是为了保护居民健康。

The results showed that : ( 1 ) Health protection zone and the atmospheric environment protection zone had the differences of the calculation principle , the parameter setting , the range , the result levels etc. But the purpose of them was protection the health of residents .
