射线检验程序

射线检验验收按照AWS D1.1/1.1M 进行验收。

7.0 SAFETY REQUIREMENTS 安全要求

7.1 Define and mark the controlled area using barrier tape refer to, notices and warning lights, i.e. an area in which levels of ionising radiation’s are likely to exceed 7.5 usv – h – 1 (7.5 micro Sv.h-1 = 0.75 mr/h). If this is not practical, make reference to distance and direction from source or the object to be irradiated. Monitor and complete the form use physical lock up of access points in an addition to warning signs and barriers and dose levels at the barrier must be completed.

如果电离辐射级可能超过7.5 usv – h – 1 (7.5 micro Sv.h-1 = 0.75 mr/h)时，应使用屏蔽带、通告及报警灯对曝光区进行限制。如该做法不可取，可参照射线源的距离及方向或被照物体加以防护，除使用报警信号及屏蔽外，须使用监视器，锁定个人辐射接近点完成在屏蔽状态下的剂量级。

7.2 The controlled area barriered off must not be left unattended whilst radiography is in progress.

射线作业时，屏蔽区外应留人看守。

7.3 Ensure that no employees are working in obscure areas, i.e. on roof, offices, large vessels on shop floor or segregated areas near exposure point.

避免员工在不稳定的区域，如房顶、办公室、车间大容器内或接近曝光点的隔离区工作。

7.4These may need to be much lower than 2.5 micro sv/h (0.25 mr/hr).

射线放射强度低于2.5 micro sv/h (0.25 mr/hr).

7.5Film badges/TLD’s must be worn when working with Ionising Radiation

电离辐射工作时，应佩戴胶片徽章。

7.6The x/ray and gamma equipment within this area shall be operated by classified

personnel appointed as radiographers or Safety officers only.

X 或伽玛射线设备应由指定的分级射线人员在该区域操作，或只由安全管理员操作

7.7Before any exposure commences, the operator shall ensure there is no one in the compound, and that the moveable screen is in place.

曝光开始前，确保无人在作业区 ，可移动防护屏位置所在其位。

7.8No person shall be allowed to remain within the compound, for whatever reason,

whilst exposures take place.
