十年来,我国各级射线检测持证人员已达1.5万人。除CT机与直线加速器等个别高精尖设备外,我国已能生产和供应国内所需的射线检测设备与器材。当前虽仍以X射线检难占绝对优势,但γ射线探伤因其检测灵敏度提高、设备重量轻和安全防护措施的加强等因素,而逐渐引人注目。近百台γ射线探伤机已投入运行,并有增长的趋势。约二十余台工业射线电视装置与约十余台直线加速器用于生产,且还在续续增加。利用核反应堆中子照相,国内也取得初步成果。工业用CT设备国内尚属空白,但CT探伤工艺研究已见报道。目前我国射线检测技术与国际先进水平相比,在检测工艺方面差距约8～10年,设备器材方面约12～15年。最后作者还展望了近期国内射线检测技术的发展方向,并针对当前存在的问题提出了对策。
In the past ten years, the number of certified radiographers at all levels in China has reached 15,000. In addition to CT machines and linear accelerators and other sophisticated equipment, our country has been able to produce and supply the required domestic radiation testing equipment and equipment. Although X-ray inspection is still the absolute predominance at present, γ-ray inspection has drawn increasing attention because of its increased detection sensitivity, light weight of equipment and enhancement of safety precautions. Nearly a hundred γ-ray flaw detector has been put into operation, and there is a growing trend. About 20 sets of industrial radiography television sets and about a dozen linear accelerators are used in production and are continuing to increase. The use of nuclear reactor neutron photography, China has also achieved initial results. Industrial CT equipment is still blank, but the CT flaw detection technology has been reported. At present, China’s ray detection technology compared with the international advanced level, the gap in the detection process is about 8 to 10 years, equipment and equipment about 12 to 15 years. Finally, the author also looks forward to the recent development of the domestic ray detection technology and proposes solutions to the current problems.
