Electron Beam, X-ray, Ethylene oxide, γ-ray as well as Vapour (which is not suitable to most of polymer materials) are recently used in the field of disinfectant technological industry. As used in the correct way, Electron Beam, X-ray, Ethylene oxide and γ-ray are of advantages and disadvantages, however, all of them are safe and effective skills for sterilizing medical products. Nonetheless, Ethylene oxide and γ-ray devices are facing threatens of controlling and securing, thus the need of replacing disinfection technology are tending to raising in the field of industrial. Radiation is a way of sterilization by killing the microbial directly and sterilizing microorganisms or parasite through chemical reactions. 

1. Electron Beam:
l So far the most affordable disinfection technological. 
l If the product is suitable for Electron Beam, it is supposed to be the best way of disinfecting.
l The most classical procedure is to let the goods in the packages absorb dose from the high energy Electron Beam in order to achieve the disinfection and sterilization.

2. X-ray:
l Providing a better penetration ability 
l Comparing to the Electron Beam, X-ray better DUR.
l The high penetration ability allows products in heap and still provides a uniform and stable dose.

3. γ-ray:
l Requiring cobalt-60 which is a synthetic radioactive isotope of cobalt.
l The most classical procedure is to hang or place the goods on a cart according to the density and dose required. 
l Due to the difficulty of solving radioactive isotope’s problem (such as supporting, transporting, and destruction. It is impossible to eliminate radiation.), it is predictable that γ-ray disinfection is going to be replaced by Electron Beam and X-ray.

4. Ethylene oxide
l It is a kind of gaseous fungicide, which requires expensive poromeric packing in order to connect the gas and the goods.
l It requires a biological detector to prove the disinfection is accomplished
l During the disinfectant process, it required an air replacement area to collect the residue of Ethylene oxide due to its carcinogenicity.
l Ethylene oxide is explosive, toxic and hard to control its pollution, therefore, it is getting hard to operate it.
