Description
Technical field
The present invention relates to a kind of shields more particularly to a kind of for shielding the shield of radioactive ray.
Background technique
Currently, when building alpha ray shield wall, firstly, determining the mechanism of barrier shield by Architectural Structure Design；Its
It is secondary, by radiation protection design, determine the shielding material and thickness requirement selected under the conditions of the source item of design requirement；Finally,
Unit in charge of construction completes the construction work of barrier shield according to design drawing.If shielding material is cement, cast-in-site is generally used
Or the method that prefabricated cement board is bottled.If shielding material is lead or steel, generally require after factory process is at large-sized structural parts
Carry out on-site consolidation.
The above method in actual operation, has following three:
1, cost factor, barrier shield limited allowance involved in radiation protection design are considered.Once source item condition occurs
Variation, the thickness of shielding material are unable to satisfy radiation proof needs, and the reconstruction work of barrier shield is very troublesome.In addition, large-scale
The installation cost of structural member is also very expensive；
2, due to the limitation of execution conditions, the construction site of some barrier shields can not employ Large-scale Hoisting equipment, large size knot
The installation of component is very difficult；
3, the assembly of large-sized structural parts also results in the adjacent surface between shielding slab and shielding slab and certainly exists a gap,
Effective shielding thickness herein is zero, that is, there are problems that radioactive ray shielding runs through.
Above-mentioned source item condition is dedicated noun in radiation protection design, refers to shielded radioactive ray device
Or radioactive source influences some indexs of radiation protection design, such as:
1, for x-ray apparatus, these indexs include ray type, energy, x-ray apparatus output quantity, shield slip,
Beam mouth geometry etc. out；
2, for radioactive source, these indexs include ray type, energy, radioactive source activity, shield slip, go out beam mouth
Geometric dimension etc..
Summary of the invention
In order to solve defect of the existing technology, one aspect of the present invention provides one kind and penetrates for shielding radioactivity
The shield of line, wherein shield includes base main body and shielding main body, and base main body is used to support shielding main body, shielding master
Body include it is multiple can be disassembled ground shielding slab, at least one shielding slab mutually can overlap or stack with adjacent shielding slab with
Shielding main body is formed, at least one shielding slab has the cross section of hexagon.Shielding slab is detachable and using the transversal of hexagon
Face facilitates overlap joint or stacking, reduces human and material resources, transportation cost and haulage time；Can ensure to overlap or stack consolidates, side
The shielding slab on boundary will not fall；Base main body is stablized, and shielding main body, which is not easy to roll, to be overturned；It can be realized modular combination, easily
In production, flexible and changeable protection.
In order to further increase the reliability connected between detachable shielding slab, it is preferable that the setting of at least one shielding slab
Tangible latch members are to carry out form locking connection with adjacent shielding slab.
