Description
Affiliated invention field
The utility model relates to the nuclear radiation shield equipment technical field, particularly relates to a kind of portable neutron source shield.
Background technology
In the nuclear radiation shield equipment technical field, because radioactivity device such as nuclear reactor, isotope neutron source and accelerator isotonic source all can produce nuclear radiation in operational process.Therefore, need to adopt effective shielding protection measure, with the personal security in protection environment place.One of effective measures of protection are exactly to adopt suitable shield material and structure, constitute the radiation-resistant glass body.Along with the use of neutron source more and more widely, particularly the requirement aspect the NEUTRON PROTECTION performance test of shielding material is more and more, and influence, the test environment of the objectivity that the size of neutron streaming or shape are estimated material shielding performance also propose higher requirement to the shield performance to the influence of test background.Traditional neutron source shield is stationary structure, the shielding material that adopts mostly is paraffin or cement, because paraffin or cement are relatively poor to the barrier propterty of neutron, reaching under the prerequisite of requirement of shelter, the use amount of material is just a lot, makes that the volume and weight of shield is very big, cause the neutron source shield very heavy, use very flexible, also be inconvenient to transport, this has also limited the usable range of neutron source shield indirectly.The problem of how to solve neutron source shield heaviness, being inconvenient to transport so that enlarge the usable range of neutron source shield, and can reduce neutron source effectively in use to the radiation effect of surrounding environment, is the important topic that faces in this area.
Summary of the invention
The purpose of this utility model provides the portable neutron source shield that a kind of volume is little, in light weight, can move, use flexibly and make things convenient for transportation arbitrarily.
In order to achieve the above object, the utility model adopts following structure, a kind of portable neutron source shield, comprise: the collimation mouth, shield, the neutron source active tunnel, anti-down fixed angles, strengthen steel ring, shield plug, dialectal switching, universal wheel and base plate, its characteristics are, shield employing polylith tygon or boracic polyethylene board dislocation lamination are piled up to be built into and are cuboid, seam between the polylith polyethylene board forms relative ladder fissure of displacement structure, and with paraffin or putty with NEUTRON PROTECTION function the slit is sealed, be with the reinforcement steel ring around the shield top; Shield one side front is recessed square space, the front, square space at shield center is inwardly passed polyethylene board and is inserted a square dialectal switching that has square collimation mouth relatively, the collimation mouth is deep into the shield center on the dialectal switching, and the dialectal switching collar extension inwardly inserts corresponding shield plug; The shield top is pipe of inwardly vertical installation from top to bottom, and as the neutron source active tunnel, neutron source active tunnel top passes shield, and neutron source active tunnel bottom then is communicated with dialectal switching collimation mouth; Shield integral body is seated on the base plate that has universal wheel, and the anti-down fixed angles chucking shield integral body that is provided with all around on the base plate constitutes portable neutron source shield.
Above-mentioned described shield is to cut required form after machining is made by tygon or boracic tygon section bar with polylith tygon or boracic polyethylene board.
Square collimation on the above-mentioned described dialectal switching mouthful can be square collimation mouthful, also can be rectangle collimation mouthful, or the square collimation mouth of distortion.
Shield plug on the above-mentioned described dialectal switching collar extension is with the shape of collimation mouthful and size is corresponding and cooperate installation with collimation mouth.
The utility model is the shield from neutron source, the material such as tygon or the boracic polyethylene board etc. that neutron are had better barrier propterty have been selected for use, carry out the design of shield, make shield to have an effect and cause moderation of neutrons with neutron, and can reduce the gamma-ray energy that to follow effectively, the material of selecting for use is processed easily, and the scantling precision controls easily, and dimensional stability is good; Can regulate the size of shield according to the size of source radiation activity, the use of shield material reaches optimization; Material adopts the method for the ladder fissure of displacement in banking process, reduce the formation in direct puncture hole or slit, with paraffin or putty with NEUTRON PROTECTION function the slit of shield is poured into then, further reduces the existence in hole or slit; The size of the collimation mouth of shield and shape can be carried out conversion as required, adapt to different request for utilizations, the collimation mouthful stepped appearance that adopts can reduce the transmission of neutron, and can be installed on easily in the shield, to obtain the neutron streaming of different cross section size and shape; Shield is installed on the flat board that has universal wheel, the dull and stereotyped thick steel plate of 1-2cm that adopts, wheel adopts universal wheel, can freely turn to, conveniently moving is in four jiaos of spacing methods in employing right angle of flat board, the height at right angle is 5-10cm, adopt the reinforcement steel ring to reinforce on the top of shield, guaranteed vehicle overall weight minimum, can guarantee stability whole in the transportation again; At different radioactive sources,, need install shield plug additional in the collimation notch portion, the security of assurance source in storage and transportation as isotope radioactive source (Cf-252).And, also can not install shield plug additional for other radioactive source, convenient, flexible.And for isotope neutron source, the neutron source active tunnel should be communicated to apart from shield bottom 10～20 centimeters, and around the neutron source active tunnel, increase lead layer, increase is to the gamma-ray protection of isotope source, and thickness of increase is 5～10 centimetres lead plug above the source, and lead plug can move simultaneously with isotope source.
The utility model makes that neutron source shield volume is little, in light weight, can move, use flexible and convenient transportation to reach goal of the invention of the present utility model arbitrarily owing to adopt the said structure principle.
