Equipment compare, production cost is greatly saved.
In some embodiments of the invention, it is preferable that radioactive source conveying device driving mechanism 406 is manual operation or electricity
Dynamic operation.
In this embodiment, radioactive source conveying device 10 can be imported by radioactive source work using manual operation or electric operating
Make in container 30.
Specifically, the inspection system provided by the invention using radioactive source, using the working method of a container, that is, is
Uniting, radioactive source is closed under normal circumstances is stored in Work container, the rotation control for sending/closing by shutter of ray.
Preferably, the shape of the shield 302 of radioactive source Work container 30 is substantially spherically-shaped, and radioactive source is located in sphere
The heart.It is to ensure Radioprotective Effect respectively to essentially identical using sphere.Beam by shutter 304 open close control.Shutter 304
Cylinder is designed as, fan-shaped throughgoing slit is opened in the centre of cylinder.When shutter 304 is opened, close to radioactive source slit it is small
Openend, ray is oriented constraint by the angle and width of slit.The driving of shutter 304 can be by electric and pneumatic reality
It is existing.
The mode that radioactive source imports Work container is as follows：1st, radioactive source Work container 30 and radioactive source storage container 402 are logical
Source conduit 404 is crossed to connect；2nd, the radiation protection that conduit 404 external demand in source is necessary；3rd, radioactive source conveying device driving mechanism is passed through
406, manually or electrically radioactive source conveying device 10 is imported radioactive source work appearance by mode by radioactive source storage container 402 at a distance
Device 30；4th, it is de- with radioactive source conveying device driving mechanism 406 after radioactive source conveying device 10 imports radioactive source Work container 30
From closed to be fixed in radioactive source Work container 30.
Therefore, radioactive source is imported after the completion of work, and radioactive source storage container 402 can be moved to other places, and a radiation
Source storage container 402 can reuse multiple devices.When radioactive source Work container 30 need to be overhauled, radioactive source can be conveyed and filled
10 are put to be recovered in radioactive source storage container 402.
In conclusion radioactive source Work container provided by the invention, because being installed in radioactive source conveying device to radioactive source work
After making container, it is fixed in radioactive source Work container by closed by locking device, works so as to fulfill using a radioactive source
Container meets that system work requirements reach radioactive sources safety requirement of shelter again, reduces financial cost, solves twin containers mould
Under formula radioactive source cannot closed the problem of being fixed on Work container, and radioactive source source of bank savings device is not easy because contingency comes off
Radioactive source Work container.
