4 定义Definition
4.1 射线检测 RT
射线检测是利用射线在穿透物质过程中吸收与衰减作用而在底片上反映不同黑度的影像,进而对被检材料进行质量评定的一种非破坏性检测手段。射线具有辐射性,对人体有一定的危害性。
RT, making use of absorption and attenuation in the process of ray penetrating material and reflecting on film with different dark image which is an NDE inspection manner by performing quality evaluation on examined material. There is some damage to persons caused by the rays because of its radioactivity. 4.2 射线检测场地 RT Work Site
在工程施工建设过程中,根据质量控制的要求,为保证射线检测正常安全的进行,由施工方提出,经总包、监理业主同意,规定或划分出某一特定区域或场所,在一定的时间段或时间周期内仅供射线检测施工使用的场地。
During the construction process, as per the necessity of quality control, to ensure the implementation of RT normally and safely, construction party shall

propose an area which is specially marked for RT and approved by Owner as well as Contractor. The relative large area specially for the implementation and construction of RT only in a particular period and time period. 4.3 检测时间
根据预制场地周边的人流量及车辆等实际情况计划检测时间安排在当日22时至次日5时。
4.4 射线检测警戒区(监督区)RT Security Area (Monitoring Area)
根据GBZ 117-2006《工业X射线探伤放射卫生防护标准》的规定,射线检测作业时,应划定警戒区(监督区)。作业时空气比释动能率大于1.5μGy/h小于15μGy/h的范围划为警戒区,并在其边界设置警示设施。在警戒区范围内,无关人员禁止入内。在警戒区边界处,不得有无关人员停留。Basing on GBZ 117-2006 Industry X-ray NDE Radiation Health Protection Specification, Security area (monitoring area) shall be marked off for RT. Air kerma rate shall be in the range from 1.5μGy/h to 15μGy/h, the area more than 1.5μGy/h and less than 15μGy/h shall be marked as the security area, and establish alerting signs around the fringe. Nonessential persons are not allowed to enter Security Area. Irrelative persons mustn’t stay around the boundary of the security area.
