Description

A kind of high-performance nuclear radiation shield device and method based on graphene nano material
Technical field
The invention belongs to nuclear radiation shield technical fields, and in particular to a kind of high-performance core based on graphene nano material Radiation shield device and method.
Background technique
The exploitation and application of nuclear radiation protection material, be the work of civilian health protection a big emphasis and nuclear energy exploitation, The important component in military protection field.In recent years, the various basic research being unfolded around nuclear energy and all kinds of ray applications Or industrial application is very much (such as nuclear power station), proposes requirements at the higher level to the protection of personal nuclear radiation shield.In space industry, various spies The moon and the other celestial bodies explorations of Mars, Enceladus, moonfall space probe, astronaut cabin is for oral administration and space walking takes be both needed to out of my cabin Carry out efficient radiation protection.It is necessary to develop a kind of light, efficient nuclear radiation shield dress ornament and associated shield technology.
Nuclear radiation is mainly tri- kinds of rays of α, β, γ, neutron and all kinds of radionuclides: alpha ray is helion, external exposure Penetration capacity is very weak, but harm is big in suction body；β ray is electron stream, and the negative electrical charge of one unit of band is burnt after irradiating skin Obviously.Both rays, as long as influencing not entering apart from closer radiation source in vivo, influence not too large since penetration power is small； But a kind of gamma-rays electromagnetic wave very short as wavelength is similar with X-ray, and penetration power is very strong, can penetrate human body and building, danger Evil distance is remote.All kinds of radionuclides include tritium, Co 60, nickel 63, selenium 75, antimony 124, iodine 131, Ce 137, radium 226, plutonium 238, right Human body harm is also very big.
To the very harmful of human body, the nuclear radiation of nuclear accident and explosion of atomic bomb can all cause that personnel's is dead immediately for nuclear radiation It dies or severe injury.Cancer, infertility, monster can also be caused.
In radiation protection, according to the height of neutron energy, neutron can be divided into slow neutron, energy that energy is less than 5keV The intermediate neutron that range is 5~100keV and the fast neutron three categories that energy is 0.1~500MeV are measured, wherein energy in slow neutron Also referred to as thermal neutron less than 1eV (generally 0.025eV).Neutron has very strong penetration power when passing through substance, produces to human body The X-ray of raw hazard ratio same dose, gamma-rays are even more serious.For human body after by neutron irradiation, stomach and male gonad can be tight It damages again, induce the biological effect of tumour is high and easily leads to Deaths, while being damaged body easy infection and degree weight, The relative biological effect of caused lens opacity of eye is 2~14 times of γ or X-ray.Cause blood forming organ failure, digestive system damage Wound, central nervous system injury.It can also cause malignant tumour, leukaemia, cataract.Neutron irradiation can also generate hereditary effect, shadow Ring raying person offspring development.
It reduces by nuclear radiation there are three main points: distance, time and shielding, i.e., 1) far from radiation source, spoke suffered by personnel Penetrate dosage square being inversely proportional at a distance from him and radiation source；2) exposure duration is reduced, dose of radiation there are cumulative effects, cruelly The time being exposed in radiation is longer, and suffered dosage is bigger；3) radiation is shielded, effective shielding can be significantly reduced Radiation suffered by personnel.
Currently, shielding the optimal method of gamma-rays be using the material of high density high atomic number, there are commonly iron, lead and Concrete material.Meanwhile the higher gamma rays of energy needs thicker shielding.Researcher also uses emulsion blending and original position also Former method is prepared for natural rubber (NR)/redox graphene (RGO) nanocomposite, and has studied gamma-ray irradiation to multiple The influence of condensation material mechanical property and thermal stability.Result of study shows that RGO is evenly dispersed with several layer heap laminate constructions In NR matrix, the addition of RGO is remarkably improved the mechanical property and thermal stability of NR, after the gamma Rays of 200kGy, The tensile strength and T50 of pure NR has dropped 75% and 4.5 DEG C respectively, and NR/RGO-0.6% compound system only has dropped respectively 56% and 1.2 DEG C, disclose the mechanism that RGO improves material radiation resistance, due to RGO can capture quenching because radiation generate from By base, to reduce the generation of Radiation degradation and cross-linking reaction.
The present invention makes full use of " king of new material " graphene and its types of functionality nanocomposite in nuclear radiation screen Field excellent characteristics is covered, for nuclear power station, space exploration different application scene, the characteristics of fully considering different nuclear radiation sources, is opened Novel high-performance nuclear radiation shield technology and the relevant technologies are sent out, provide one of green screen for people's health.
