Description
Technical field
The present invention relates to radiation protection field, especially gamma-rays, X-ray, neutron integrated protection product scopes, specifically
Refer to a kind of multilayer radiation protection gloves and its manufacture craft.
Background technique
What the research and processing of nuclear material usually carried out in the more complicated place of radiation environment, wherein there may be
A variety of rays such as α, β, γ, X-ray and neutron, γ, X-ray and neutron penetration power are strong.Neutron source is often radiated with γ, such as
Radionuclide neutron source and pile neutron source itself are also gamma emitter, only strong and weak different.And when neutron with
When target, shielding material and other objects act on, capture gamms can be also generated.Therefore need to consider neutron and gamma-ray synthesis
Protection.
Gamma-rays has the characteristics that wavelength is short, penetration power is strong.Skin by gamma-ray direct projection and scattering, will lead to for a long time
Skin occur pityriasis rubra papule reacted with depilation reaction, erythematous response, bubble, downright bad ulcer reaction, canceration etc. in various degree
Damage.To reduce damage of the gamma-rays to skin, protected.Damage of the X-ray to human body is similar with gamma-rays, to γ
The protection of ray can refer to the protection to X-ray, can be protected with identical protective materials gamma-rays or X-ray, generally
Using the gamma-rays of material protection containing heavy metal element or X-ray.
Neutron penetration power is strong, and shielding is difficult, and biological damage is big.Neutron is generally protected using the low material of atomic number.
The period of the day from 11 p.m. to 1 a.m is typically all and operates in glove box in operation, and the chance that hand is irradiated is more, it is therefore desirable to prevent hand
Shield.The protection to hand is generally realized by the way of dressing radiation-resistant gloves.
