Abstract
The utility model discloses a single row radioactive source in straight line arrangement for gamma ray irradiation devices. 23 holes which radiate along the same center of the circle are evenly distributed on the same straight line with the radioactive source clamp. A cobalt 60 radioactive source is put into an inner housing and an inner cover is covered. The inner housing is installed into an outer housing and an outer cover is covered. 22 components provided with cobalt 60 radioactive sources are installed into the corresponding holes radiating along the same center of the circle with the exception of the centre hole, and the cover of the radioactive source clamp is covered. The weight of the single row radioactive source in straight line arrangement is relatively light, so that the device can easily implement complicated compound motion. As the radioactive sources are integrated in one source clamp, when the source are changed, installing the source component into the source clamp are only required firstly. The changing of the radioactive sources can be implemented by changing the source clamp at one time, and thus, the efficiency of changing the sources is improved. By changing the straight line arrangement of the source components into two rows or three rows arrangement, the fan shaped angle can be reduced, the volume of the irradiation device can be reduced, and the irradiation device has great flexibility.
Description
Affiliated technical field
The utility model relates to the single line spread radioactive source in a kind of gamma ray radiator.
Background technology
The spread pattern of existing gamma ray radiator radioactive source is: on sphere, distributes with certain longitude and latitude, or the certain regional inside spin distribution on sphere, or along a certain section arranged distribution of circumference.The radiation appliance volume of these structures is big, weight is heavier, and it is very difficult to make that dress changes the source.And radiation appliance can not be done complicated resultant motion, installs and removes also very inconvenient.
Summary of the invention
The purpose of this utility model is to provide that a kind of shared spatial volume is little, weight is light, change the source single line spread radioactive source in the gamma ray radiator easily.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
Press from both sides at radioactive source and to be evenly equipped with along hole that the same center of circle width of cloth is penetrated totally 23 on the same straight line, radioactive source 60 cobalts are put into inner housing middle cover inward upper cover, inner housing is packed into and is covered enclosing cover in the shell body, it is corresponding along in the hole that the same center of circle width of cloth is penetrated that 22 assemblies that radioactive source 60 cobalts are housed are respectively charged into except that center pit, covers radioactive source folder lid.
Each assembly of radioactive source 60 cobalts is housed, be respectively charged into the center line be benchmark in the hole of both sides radiation, the center line angle of its adjacent holes is: α=50 °/22.
The utility model is compared with background technology, and the useful effect that has is:
1, the utility model provides a kind of single line spread radioactive source, and the shared spatial volume of source component is little, still can realize smaller volume after shield around adding and the funtion part; So the weight of single line spread radioactive source is also lighter, device is realized complicated compound motion easily;
2, radiation source assemblies of the present utility model is integrated in the source folder, needs only when dress changes the source in the source folder of earlier source component being packed into, and disposable replacing source folder can realize changing radioactive source, changes source efficiency and improves;
3, the arrangement of radiation source assemblies of the present utility model can also be changed into line spread and becomes double or three rows, dwindles fan-shaped angle, can reduce the volume of irradiation devices equally, and dirigibility is very big.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;
Fig. 3 is the structure enlarged diagram of radiation source assemblies.
Among the figure: 1. radioactive source presss from both sides, 2. radioactive source folder lid, 3. hole, 4. shell body, 5. inner housing, 6. radioactive source 60 cobalts, 7. inner cap, 8. enclosing cover.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model presss from both sides at radioactive source and is evenly equipped with along hole 3 that the same center of circle width of cloth is penetrated totally 23 on the 1 same straight line, radioactive source 60 cobalts 6 are put into inner housing 5 middle cover inward upper covers 7, inner housing 5 is packed into and is covered enclosing cover 8 in the shell body 4, it is corresponding along in the hole 3 that the same center of circle width of cloth is penetrated that 22 assemblies that radioactive source 60 cobalts 6 are housed are respectively charged into except that center pit, covers the radioactive source folder and cover 2.
Each assembly of radioactive source 60 cobalts 6 is housed, be respectively charged into the center line be benchmark in the hole of both sides radiation, the center line angle of its adjacent holes is: α=50 °/22.
This radioactive source 60 cobalts 6 inner housing 5 of packing in special-purpose hot cell reaches envelope inner cap 7 and welding behind the dosage of regulation.Inner housing 5 shell body 4 of packing into, envelope enclosing cover 8 also is welded into an assembly, and inner housing 5, inner cap 7, shell body 4, enclosing cover 8 are stainless steel material.22 radiation source assemblies are packed in the hole 3 of radioactive source folder 1, insert and consist of a conglomerate after the radioactive source folder cover 2, and it is tungsten 95 materials that radioactive source presss from both sides 1.When dress changes the source, as long as disposable replacing radioactive source folder conglomerate changes source efficiency and improves.
The arrangement that radioactive source of the present utility model presss from both sides endogenous body can also change over double or three rows, and the width (fan-shaped angle) of source folder can dwindle, and the volume of radiation appliance can be changed into another mode, even reduces the volume of irradiation devices.Do not arrange because the source body is not sphere or covering of the fan, the thickness or the height of radioactive source folder can reduce.After adding the outside shield and funtion part all around of source folder, the volume of radiation appliance also just can be done lessly, and weight also just alleviates.Its result makes the dress of radiation appliance change the source ratio and is easier to carry out, and makes radiation appliance can do complicated resultant motion.
