Radiation sterilization
Radiation sterilization in certain conditions using rays for sterilization methods. More commonly used are ultraviolet light, and other ionizing radiation (ray accelerated neutron, etc.). Wavelength of 25000 ~ 80000 nanometers between the laser also has a strong ability to sterilize the wavelength of 26500 nanometers is the most effective. Radiation sterilization method is limited to a certain material, due to the complexity of the equipment required, difficult to use widely.
Radiation sterilization
1, radiation sterilization method, including radioisotopes, including the use of gamma rays from a radioactive source for irradiation, is a method of killing microorganisms. This method, mainly for glass products, magnetic products, metal products, rubber products, plastic products and fiber products and other items resistant to radiation. Usually, the radioactive sources used are 60CO, 137C5, etc. The total amount of irradiation is adjusted according to the material, character and contamination status of the sterilized articles to achieve the purpose of sterilization.
2, ultraviolet sterilization method, is the use of irradiation of ultraviolet light to kill microorganisms of a method. This method is mainly used for glass products, metal products, rubber products, plastic products and fiber products, etc., can also be used for facilities, equipment, water or pharmaceuticals, etc., these items should be ultraviolet light has a good tolerance, usually, the general application of the ultraviolet light of 200-300nm.
3, high-frequency sterilization method, is directly with irradiation of high-frequency heat to kill microorganisms of a method. This method is mainly used for water, culture medium, test liquids and liquid pharmaceuticals and other items resistant to high-frequency irradiation. Usually use 915 or 2450 megacycles of frequency.
The above content from wikipedia, here the electronic irradiation should be referred to as high-frequency sterilization, that is, the use of high-frequency electromagnetic field generated by the circuit to sterilization, this technology is not difficult, there is a high-frequency sterilization machine, which consists of a sun plate DC power supply, filament power supply, high-frequency oscillator, the control and protection of circuits and indication circuits and feeding mechanism, the use of high-frequency electric field on the material to be heated and sterilized, heating fast, the surface of the material and internal heating at the same time, uniform heating, high thermal efficiency, suitable for sterilization of traditional Chinese medicine, canned goods, food, etc., you that the principle of the experimental supplies should be similar to this high-frequency sterilizer.
