Irradiation technology


Principle and application of electron irradiation technology

   Radiation treatment refers to the transfer of gamma-ray energy generated by an electron beam (gamma ray) or a radioactive isotope (Cs-137 or Co-60) generated by an electron accelerator (0.2 MeV~10 MeV) to a radiation substance and ionizing radiation. Upon irradiation to the irradiated substance, ionization and excitation are generated, orbital electrons are released, free radicals are formed, and the physical properties and chemical composition of the irradiated substance are changed by controlling the radiation conditions, and can be provided by a person. A new substance that causes loss and destruction of unrecoverable organisms (microorganisms, etc.) to achieve the desired goal. This new processing technology is called radiation processing technology. For example, polymeric materials are grafted, polymerized, cleaved, or crosslinked, respectively, to inhibit or stimulate biological growth, and to effectively kill pests, eggs, bacteria, and the more like this.
The advantages are summarized as follows:
1. The process is simple and easy.
2. Energy-saving, high processing efficiency: The heat treatment and heat treatment energy consumption are only 1 / 40-1 / 200; it is 1 / 20 of the freezing method.
3. No environmental pollution; no chemical residues; no damage to the appearance quality and intrinsic properties of processed products.
4. No impurities are introduced during processing; it can be packaged and processed to increase efficiency without causing secondary pollution.
5. Does not change the temperature of the processed material, also known as cold working.


   Irradiation technology has broad application prospects and can be combined with various industries of the national economy to form new industries or form new economic growth points. There are many aspects to summarizing radiation processing applications. Currently, industrial and commercial applications include food irradiation preservation, radiation sterilization of medical products, radiation chemistry, and three waste treatment.

Food industry applications of irradiation technology


Industrial application of irradiation technology

   By irradiation, long linear macromolecules between polymer materials form a network structure by some form of the chemical bond, which can greatly enhance the bonding force between the polymers, thereby improving the thermal stability of the material and impeding flammability. Product stability, drip resistance, strength, and stress crack resistance. There are many methods of irradiation, such as X-rays, high-speed electron flow, and the like. Applications include building wiring, automotive wiring, heat-resistant electronics, and military applications.

Industrial application of irradiation technology

Irradiation technology in food technology

   This is a technique for radiation sterilization using radioactive elements that have been widely used in food technology. Although this technique has a good bactericidal effect, it may change the taste of the food if it is not well controlled. To this end, the State has established relevant irradiation standards in strict accordance with this dose and requires that the words of irradiation be marked on the packaging of irradiated food.


Irradiation technology

   As can be seen from the above, the application fields of irradiation technology are very extensive. Radiation processing technology has proven to be a high-tech that is moving towards industrialization and commercialization. It also shows that radiation processing technology is a very important task.
