在γ辐照装置特别是科研型的γ辐照装置中,被辐照物吸收剂剂量的均匀度是极为重要的参数。它直接决定了被照物的辐照质量、科研产品的剂量精确度、放射源的能量利用率和整个装置的处理能力、经济效益以及装置本身的建设水平。我们根据科研型γ辐照装置研究项目的需要,为提高研究水平,设计了旋转辐照台。辐照合本身既能绕放射源公转,在台上不同半径位置的12个放置被照物的小转盘又能自转,只采用一个动力源,设备结构简单、紧凑、噪音小、运行平稳、控制方便,除远距离控制外还能就地操纵。该设备的应用不但提高了被照物吸收剂量的均匀性,而且能在吸收剂量上达到重演性。该设备对科研和中试具有重要的实际意义。
In gamma irradiation devices, especially in research gamma irradiation devices, the uniformity of the dose of radiation absorbed is of paramount importance. It directly determines the irradiation quality of the object being illuminated, the dose accuracy of the research product, the energy utilization rate of the radioactive source, the processing capacity of the entire apparatus, the economic benefits, and the construction level of the apparatus itself. According to the research project of research-type γ irradiation device, we designed a rotary irradiation stage to improve the research level. Irradiation itself can not only revolve around the radioactive sources, the position of different radii on the stage 12 small turntable placed under illumination and rotation, only one power source, the device structure is simple, compact, low noise, stable operation, control Convenient, in addition to long-distance control can also be manipulated locally. The application of this device not only improves the uniformity of dose absorbed by the object, but also achieves the repeatability of absorbed dose. The device has important practical significance for research and pilot.
