Background technology
It in study of high energy physics, generally requires to build Low background laboratory, to reduce nature background ray to testing number
According to interference.Research shows that background is mainly made of four aspects in natural laboratory:Radon, earth day in cosmic ray, air
The radiation that right γ radiation and construction material Radionuclide generate.
According to the natural background radiation feature that above four aspects are formed, Monte Carlo (MCNP 4C) is carried out by computer and is built
Formwork erection is intended space and is calculated, it is necessary to is used in mixed way using a variety of shielding materials, can be only achieved ideal background target control value.
1st, the cosmic ray of vertical incidence is high-energy ray, and effective dose is in the object across 50g/cm2 equivalent depths
When decay 7%, certain thickness concrete shield housing can effective high energy cosmic ray of the shielded segment from top
2nd, three big radioactive series of earth natural gamma radiation, according toCertain thickness concrete shield housing (50g/
Cm2 its influence can be ignored under thickness protection);
3rd, the radon in air can ignore its influence after excluding radon gas aggregation by technological means such as ventilations;
4th, the concrete radiation that (material) nucleic generates in itself cannot rely on coagulation in outer concrete shield shell material
Soil shielding, the application is using both having old lead and steel plate that high shielding properties radiated but also with itself Low background as intershield
Housing, modularization making become leaded steel protective shielding module, with concrete in shield external layer concrete shield case material in itself
The radiation that (material) nucleic generates.
A kind of existing integral sealing welded type shielding Low background laboratory, the sealing of shielded body integral solder is surrounded
Come so as to achieve the effect that alpha ray shield, but since the lead hardness as main internal layer shielding material is smaller, internal layer shielding material
It can drop in use for some time and upper-thin-lower-thick situation is caused to influence shield effectiveness, to continue to ensure laboratory shielding target control
Value processed needs lead screen material to reverse, and the structure of integral sealing welded type, which cannot safeguard laboratory, to be carried out reversing balance more
Newly, it can be risen all the way using the background values in rear laboratory for a long time, influence using effect.
Utility model content
The purpose of this utility model is to provide a kind of advantages of good shielding performance, low-activity and easy for installation it is applied to low
The modularized combination type alpha ray shield housing in bottom laboratory.
Technical solution adopted in the utility model is:
A kind of modularized combination type alpha ray shield housing applied to Low background laboratory is securable to including several on wall
Wall panel element, each wall panel element includes inner plating and lamina rara externa, has interlayer between inner plating and lamina rara externa, fill in interlayer
There is radiation proof material, the U-bend that the left end of inner plating has outward opening is rolled over, and the right end of inner plating, which has, to be sloped inwardly and be used for
The ladder bending being connect with wall, the L-shaped that the left and right ends of lamina rara externa have outward opening are bent, the L-shaped bending overlap joint U-shaped of left end
Bending makes wall panel element form protrusion in left end, and it is recessed that the L-shaped bending overlap joint ladder bending of right end makes wall panel element be formed in right end
Slot, the protrusion of wall panel element are inserted into the continuous splicing of groove realization of adjacent wall board unit.
As the improvement of said program, the bending of each ladder includes interior ladder and the outer ladder for connection wall, interior ladder and
The bending overlap joint of lamina rara externa right end.
As the improvement of said program, the surface of each groove is equipped with rubber cushion.
As the improvement of said program, radiation proof material is lead, and inner plating and lamina rara externa are steel plate.
The beneficial effects of the utility model:This is applied to the modularized combination type alpha ray shield housing packet in Low background laboratory
Several wall panel elements that can be connected from beginning to end are included, due to the setting using wall panel element head and the tail connection, the not only structure letter of entire housing
Installing component that is single and can avoiding using bolt etc to the maximum extent, while groove and protrusion are interlocked, convenient for hiding necessity
Bolt etc installing component, ray is effectively avoided to be overflowed after multiple refraction, more fully blocks the radiation of construction material.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the vertical view of wall panel element;
Fig. 2 is the vertical view of inner plating;
Fig. 3 is the vertical view of lamina rara externa;
Fig. 4 is several wall panel elements schematic diagram mounted to a wall.
Specific embodiment
With reference to Fig. 1~Fig. 4, on the basis of the orientation in Fig. 1 up and down, direction refers to inside, i.e. one close to wall upwards
Side;Direction is downwards outside, and lines belong to simplified painting in figure.The utility model is a kind of mould applied to Low background laboratory
Block combined type alpha ray shield housing, including several wall panel elements being securable on wall, each wall panel element includes 1 He of inner plating
Lamina rara externa 2 has interlayer, has in interlayer filled with radiation proof material, the left end of inner plating 1 between inner plating 1 and lamina rara externa 2
The U-bend folding 11 of outward opening, the right end of inner plating 1 have the ladder bending 12 to slope inwardly and for being connect with wall, outer layer
The left and right ends of plate 2 have the L-shaped bending 21 of outward opening, and the 21 overlap joint U-bend folding 11 of L-shaped bending of left end makes wall panel element exist
Left end forms protrusion 3, and the 21 overlap joint ladder bending 12 of L-shaped bending of right end makes wall panel element form groove 4, wall panel element in right end
Protrusion 3 be inserted into adjacent wall board unit groove 4 realize continuous splicing.
Referring in particular to Fig. 2, since left side, inner plating 1 extends downwardly to the right upwards successively, forms U-bend folding 11 at this time,
It then proceedes to extend to the right, forms the main plane for blocking radiation;Hereafter, inner plating 1 extends into the right upwards twice repeatedly
Ladder bending 12, is consequently formed interior ladder 121 and in outermost outer ladder 122.Since left side, lamina rara externa 2 successively to
