Technical field
The utility model relates generally to a kind of novel ionizing radiation irradiation special equipment, substitutes the radioactive nucleus irradiation technique of current extensive employing by the controllable Novel X-ray technology that does not produce the pollution of environment activity nuclear matter.The utility model belongs to ionizing radiation irradiation apparatus technical field.
Background technology
Utilize the strong penetrability of ionizing radiation and the irradiation dose biological effect to organism, the mankind since last century along with peaceful utilization of atomic energy slogan is extensively applied to nuclear radiation technology such as food fresh keeping, sterilisation of objects sterilizing pesticide, irradiated biological effect study, treatment of blood products (preventing transfusion reaction) etc. various applications, also obtain very great society economic benefit, irradiation is with nuclear radiation source thereby be widely used.Special in the blood product irradiation that prevents transfusion reaction, Co60 kind of blood exposing machine is also more generally using.Due to the uncontrollable characteristic of nuclear radiation, nuclear radiation source is being manufactured, transport, store and finally scrap after all produce the radiation to around always.Due to the natural decay of radionuclide, the required exposure time of nuclear radiation equipment must constantly extend in time from dispatching from the factory, while reaching the nucleic half-life, (if Co60 is 5.3 years) exposure time must increase by 1 times, the radioactive source that before eventually can scrapping with long needs of used time, radioactive source more renews.And the production of radioactive source, transport, stores, and changes and the processing of useless radioactive source, all may cause nuclear radiation harm to personal security around.So the public of environmental protection personage and vast care environmental protection is by various legislations, from the beginning using nuclear radiation source as having the strictly management and control of dangerous material that environment is produced to radioactive nucleus pollution potential threat.Along with the continuous reinforcement of Public environmental attitude, and the serious consequence of the nuclear matter leakage accident being occurred generation baneful influence, this management and control is also in continuous reinforcement.Since the eighties in last century, people start to substitute nuclear radiation for irradiation industry by the ionizing radiation that for example accelerator of controlled ionizing radiation technology and Roentgen apparatus produce, wish finally thoroughly to break away from the dependence to nuclear radiation source, eliminate environment is produced to radioactive nucleus pollution potential threat.But accelerator exists equipment volume large, expensive, complex management, the shortcomings such as operating cost height.Analyze technically, although its emittance is high, beam intensity is limited and cross section is limited, as requires large area irradiation to need scanning increase equipment complexity to reduce irradiation intensity.X-ray device is simply too much with respect to accelerator.X-ray device is to be widely used in medical imaging diagnosis traditionally, and industrial imaging Non-Destructive Testing and public safety image check, also promote at development so far.From the nineties in last century, the U.S., many manufacturers of state such as Japan start x-ray equipment replacement Ce 137 or the Co 60 radioactive source of design production special bio sample irradiation, because radiation is completely controlled, do not exist radioactive nucleus to process problem, irradiation cavity volume is little, protects perfect, be subject to user and environmental administration's popular welcome, comprised in the whole world that so far China market is promoted.But because the existing X kind of blood exposing machine for blood product irradiation is also substantially by import, its irradiation efficiency is lower, and higher being also difficult to of price competes with domestic Co60 kind of blood exposing machine in price, cause the basic or world of Co60 kind of blood exposing machine in the current blood irradiation application of China, run in the opposite direction with the main flow of international environmental protection sustainable development.
