Protect mortar.
Background technology
Nuclear power is the energy of a kind of cleaning, highly efficient and relatively safety.Nuclear power station generation nuclear leakage accident,
Refer to that the radioactive substance in nuclear reactor leaks, cause environmental pollution and make the public by radiation hazradial bundle.
Therefore, grasp knowledge of some reply nuclear leakage to provide against any misfortune or necessary.The feelings that nuclear leakage is general
Condition shows radioprotective to the impact of personnel, also referred to as radioactive substance, and radioactive substance is with ripple or microgranule
A kind of energy that form is launched just makes radioprotective, nuclear explosion and nuclear accident have radioprotective.It has a, b
With tri-kinds of forms of radiation of y.As long as a radiation just can be blocked with a piece of paper, but in suction body, harm is big；b
Radiation is high-velocity electrons, and after skin is stained with, burn is obvious；Y radiation is similar with X-ray, can penetrate human body
And building, damage effect distance is remote.
It is many that universe, nature can produce radioactive material, but harm is the biggest, only nuclear blast
Personnel could be caused injures and deaths by fried or nuclear power plant accident leakage radioactive substance on a large scale.Radioactivity
Material can be sucked by breathing, and skin wound and digestive tract are absorbed into internal, causes interior radiation, y spoke
Penetrate and can penetrate certain distance and be absorbed by organisms, make personnel be injured by external exposure.Interior external exposure is formed and puts
The symptom penetrating disease has: fatigue, giddy, insomnia, skin rubefaction, ulcer, hemorrhage, alopecia, white blood
Sick, vomit, diarrhoea etc..The most also can increase cancer, distortion, heritability pathological changes incidence rate, impact
The health of several generations.Generally, the emittance that health accepts is the most, and its radiation sickness symptom is the most serious,
Carcinogenic, teratogenesis risk is the biggest.
Existing anti-nuclear radiation mortar be by cement-based gelling material, heavy aggregate, containing light element aggregate and
Additives etc. form, the anti-material of core of the most complementary construction after stirring with water.But existing anti-core
Radiation mortar there is problems in that 1, alpha ray shield poor performance, and radioactive substance is directly through body of wall pair
Biology works the mischief；2, water resistance is poor, perishable, and the time one can produce nuclear leakage；3, no
Tool flexibility, easy to crack；4, the phenomenons such as layering, isolation and sagging are easily produced.It it is more than the anti-spoke of nuclear power
Penetrate mortar technical staff's urgent problem.
