Description
Technical field
Radiation-screening board technology field is the utility model is related to, neutron gamma spoke is shielded more particularly to a kind of high-performance
The radiant panel penetrated.
Background technology
With the high speed development of modern science and technology, the dependence to the energy is all the more strong, and one kind is not seen, impalpable pollution
Source is increasingly subject to the concern of all circles, and here it is the radiation for being known as " stealthy killer ", therefore, how to reduce radiation intensity,
Effectively prevent radiation pollution, environmental protection, protects health, be constantly subjected to pay attention to extensively, neutron is that unique one kind can make it
Its material has a material of the ionising radiation of radioactivity, when neutron current and matter interaction, the mainly atomic nucleus with material
Interaction, thus easily generates fragment, and then triggers secondary radiation (such as X, gamma ray).Traditional radiation-proof plate is big
It is made of the materials such as mixed mud, heavy metal mostly, function is single, its radiation-proof effect is undesirable, it is impossible to meet shielding mixed radiation
The demand of field.
Utility model content
Technical problem to be solved in the utility model is how to improve the radiation-screening effect of radiation-proof plate.
In order to solve the above technical problems, the utility model provides a kind of radiation of high-performance shielding neutron gamma radiation
Plate, it is characterised in that：Including composite absorption layer, the both sides of the composite absorption layer are respectively equipped with the first lead layer and the second lead layer,
And first lead layer is arranged on composite absorption layer close to the side of radiation source；
The composite absorption layer cross section is in wavy, wavy the composite absorption layer and the first lead layer and the second lead layer
Between form gap, be filled with shielded layer in the gap.
Technique effect：First lead layer and the second lead layer can largely stop that neutron gamma radiates, composite absorption layer
Radiated for absorbing, i.e. radiation sequentially passes through the first lead layer, composite absorption layer, the second lead layer, shields one by the first lead layer first
Part, remainder pass through composite absorption layer, are absorbed a part, and remainder is largely shielded by the second lead layer, and will be multiple
Close absorbed layer and be arranged to wavy, the entire area of composite absorption layer can be increased, so as to increase the degree of absorption to radiation, i.e.,
Radiation is reduced through the amount of plate, and is filled with the gap formed between composite absorption layer and the first lead layer and the second lead layer
Shielded layer, can further improve the radiation-screening effect of plate.
The technical solution that the utility model further limits is：
Further, the shielded layer is shielding putty layer.
A kind of radiant panel of preceding high-performance shielding neutron gamma radiation, the composite absorption layer is by some compound
Grain and some shots composition.
A kind of radiant panel of preceding high-performance shielding neutron gamma radiation, the diameter of the composite particles and shot are equal
For 1.5mm-3mm.
A kind of radiant panel of preceding high-performance shielding neutron gamma radiation, first lead layer and the second lead layer are mutual
Remote side is equipped with adherent layer.
A kind of radiant panel of preceding high-performance shielding neutron gamma radiation, the adherent layer is polytetrafluoroethylene ethylene layer.
The beneficial effects of the utility model are：
（1）Shielded layer is set to shielding putty layer in the utility model, shielding putty has stronger radiation-screening effect,
In addition, shielding putty can make composite absorption layer be glued together with the first lead layer and the second lead layer after curing, make plate construction
It is more stable；
（2）Composite absorption layer is made of some composite particles and some shots in the utility model, and composite particles are used to inhale
Radiation is received, shot adulterates wherein, and on the one hand radiation can be stopped, on the other hand can change radiation to radiation reflective
Path, make in radiation reflective to composite absorption layer, increase path of the radiation in composite absorption layer, on the one hand can make multiple
Close absorbed layer and sufficiently absorb radiation, on the other hand due to changing the path of radiation, so that reducing radiation penetrates stereotype two
Ability, that is, improve shield effectiveness of the whole plate to radiation；
（3）The diameter of composite particles and shot is 1.5mm-3mm in the utility model, can make to fill out in composite absorption layer
More composite particles are filled, and then sufficiently absorb radiation；
（4）Adherent layer in the utility model can prevent dust from adhering on the first lead layer and the second lead layer, can make
Plate surface is cleaner.
