Radiations Sterilization

Sterilization through radiation depends upon the wavelengh, intensity, and duration.

Ionising Raditions: - Those ionisations radiations which have less than 1 nm wavelength because of ionisation or to become ions.

For example: - Gamma rays when they react with DNA of microbes its chromosomes get mutate and proves to be lethal for the organisms. They have more penetration power. There generation is very difficult and costly.

Non-ionising Radiations: - These non-ionising raditions have wavelength ranging from 1 nm to 380 nm. They donot ionise the media for for example U.V rays. When U.V rays passes through the DNA of microbes, it breakes the bond between the T=A and causes the bond formation between T=T and A=A called thymine dimer.

Disadvantages: -

1. Their penetration power is very low.
2. They are harmful for human being.
