1. What are the nuclear radiation protection products
Nuclear radiation protection products mainly include the following categories:
1. Radiation protection clothing: This is a type of clothing specially designed for nuclear radiation protection. It is usually made of lead material and can effectively reduce the harm of radioactive materials to the human body.
2. Radiation-proof glasses: These glasses are usually made of tungsten material, which can block the damage of radiation materials to the eyes and protect the eyes from radiation damage.
3. Radiation protection mask: This is a protective device that covers the entire face. It is usually made of lead material and can block the damage to the face caused by radioactive materials. .
4. Radiation-proof gloves: These gloves are usually made of lead material, which can block the harm of radioactive materials to the hands and protect the hands from radiation damage.
5. Radiation protection patch: This patch is usually made of lead material and can be directly attached to clothing or skin to block radiation substances. effect.
6. Radiation-proof crib: This is a bed specially designed for babies. The bed is usually surrounded by radiation-proof materials, which can effectively protect the baby from radiation. Radiation damage.
In addition to the above products, there are also some radiometers, radiation detectors and other equipment that can be used to monitor and measure the radiation in the surrounding environment to help peopleWe better understand radiation risks and take appropriate protective measures.
2. Anti-radiation *** materials
1. Prevention Penetrating radiation materials: Anti-penetrating radiation materials include radiation-proof concrete, lead steel and other heavy metal materials, ordinary concrete, clay brick masonry, compacted soil, graphite, radiation-proof glass, radiation-proof rubber plastic, etc.
2. Surface radiation protection materials: Surface radiation protection materials include organic plates, coatings, metal materials and inorganic non-metallic materials. Of course, radiation protection materials can also be classified according to their chemical composition, such as metallic materials, inorganic non-metallic materials, polymer materials and organic and inorganic composite materials.
3. The best material to prevent nuclear radiation
1. Hello, the best material to stop nuclear radiation is lead. Lead is dense, has a high atomic number and electron density, and therefore is able to absorb most alpha, beta and gamma radiation.
2. In addition, lead also has good corrosion resistance and high temperature resistance, and is suitable for the protection of nuclear reactors and nuclear medical equipment. However, it is important to note that lead itself also produces X-rays, so other materials such as tungsten need to be used when performing X-ray inspections.
4. Anti-radiation items
1: Food items : Tomatoes, seaweed, green tea, black fungus, black sesame
2: Pharmaceuticals: sodium lipoate, amine anti-radiation drugs. Chrysanthemum tea and green tea can also resist radiation. Herbal anti-radiation drugs, such as madder extract. Zymosan anti-radiation drugs can also be used, and vitamin C can also protect against radiation. You can also buy a cactus and place it at home, which can also help with radiation resistance.
1: Take blocking measures. Adding a thick enough shielding layer between the person and the radiation source can reduce the external radiation dose. The main materials are lead, reinforced concrete, water, etc. The building we live in is a good shield from external radiation.
2. People themselves wear more long-sleeved clothes, especially clothes made of rainproof silk
3. Use more iodine-containing substances, appropriately every dayIncrease vitamin supply.
The principle of radiation protection requires both internal and external protection. The principle of protection from external exposure is to shorten the exposure time as much as possible, stay as far away from the radioactive source as possible, and pay attention to shielding and use lead plates, steel plates or walls to block or reduce the intensity of exposure.
Specific measures: When radioactive materials are released into the atmosphere and smoke passes through, it is necessary to enter the building in time and close the doors, windows and ventilation system.
The protection principles for the second category of internal exposure are to avoid ingestion, reduce absorption, speed up excretion, avoid staying in polluted areas, remove pollution, and reduce internal pollution of personnel Chance.
5. What are radiation protection materials
1. Metal fiber Radiation protection materials. Metal fiber radiation protection materials are currently the most frequently used radiation protection materials. It is mainly made by blending stainless steel metal fibers and textile fibers. Its radiation protection principle is mainly shielded by the ring current formed by the metal wire in the fiber part, which can shield more than 30DB of electromagnetic radiation in daily life.
2. Silver fiber radiation protection material. Silver fiber radiation protection material is currently the mainstream material for making silver fiber radiation protection clothing. It is made by covering the surface of the fiber with silver ions through high-tech technology. The principle of radiation protection is mainly achieved by utilizing the radiation protection properties of silver ions, which can shield electromagnetic radiation hazards of more than 60DB in daily life. In addition, silver ions also have antibacterial and deodorizing effects, so silver fiber radiation protection materials are ideal materials for making silver fiber radiation protection clothing.
6. Which radiation protection materials are easier to use
1 , Radiation protection clothing generally uses two materials. One is cotton yarn wrapped around stainless steel filaments, which has good air permeability and is resistant to washing. Because the metal wire has low resistance, it can shield and absorb electromagnetic waves.
2. The other is to plate the surface of the cloth with conductive and wave-absorbing metal ions. The radiation protection performance of this material can reach 60dB, but its air permeability and washability are poor. Both materials are widely used abroad.
About radiation protection materials, this ends the introduction of radiation protection. I hope it will be helpful to everyone.
