3rd connecting portion 1044 of radioactive source conveyer device 10 is connected with the source cable of shaking and is driven by radioactive source conveyer device
In motivation structure 406 enters radioactive source Work container 30 and after locking means 20 locking, source conduit 404,
Radioactive source storage container 402 and radioactive source conveyer device drive mechanism 406 can be used for the work of other radioactive sources and hold
Device, with the equipment phase that radioactive source Work container needs the twin containers used with transport container storage container combination
Ratio, is greatly saved production cost.
In some embodiments of the invention, it is preferable that radioactive source conveyer device drive mechanism 406 is manual
Operation or electric operating.
In this embodiment, manual operation or electric operating is used all can be imported by radioactive source conveyer device 10
In radioactive source Work container 30.
Specifically, the inspection system utilizing radioactive source that the present invention provides, use the work side of a container
Under formula, i.e. system health, radioactive source is airtight leaves in Work container, the sending/close by soon of ray
The Spin Control of door.
Preferably, the shape of the shield 302 of radioactive source Work container 30 is substantially spherically-shaped, radioactive source position
In ball centre.Spheroid is used to be to ensure that Radioprotective Effect is respectively to essentially identical.Beam is by shutter 304
Open close control.Shutter 304 is designed as cylinder, and fan-shaped throughgoing slit is opened in cylindrical centre.When soon
When door 304 is opened, near the little opening of the slit of radioactive source, by the angle of slit with width to ray
It is oriented constraint.The driving of shutter 304 can be by electric and pneumatic realization.
The mode that radioactive source imports Work container is as follows: 1, radioactive source Work container 30 holds with radioactive source storage
Device 402 is connected by source conduit 404；2, the radiation protection that source conduit 404 external demand is necessary；3, pass through
Radioactive source conveyer device drive mechanism 406, the most manually or electrically mode is by radioactive source conveyer device 10
Radioactive source Work container 30 is imported by radioactive source storage container 402；4, radioactive source conveyer device 10 imports
After radioactive source Work container 30, departing from radioactive source conveyer device drive mechanism 406, airtight being fixed on is put
Penetrate in source Work container 30.
Therefore, after radioactive source importing work completes, radioactive source storage container 402 can be moved to other place, and
Multiple devices can be reused by one radioactive source storage container 402.When overhauling radioactive source Work container
When 30, radioactive source conveyer device 10 can be recovered in radioactive source storage container 402.
In sum, the radioactive source Work container that the present invention provides, because installing to putting at radioactive source conveyer device
After penetrating source Work container, it is fixed in radioactive source Work container by airtight by locking device, thus realizes making
I.e. meet system work requirements with a radioactive source Work container and reach again radioactive sources safety requirement of shelter, reduce
Financial cost, solves radioactive source under twin containers pattern and airtight can not be fixed on the problem of Work container, and
And radioactive source source of bank savings device is difficult to come off radioactive source Work container because of contingency.
