Give advantages, disadvantages and applications of sterilization by ionising radiation.

1 Answer

Answer :

Advantages:

 The method is reliable and can be accurately controlled

 No degradation of media during sterilization, thus it can be used for thermally labile media

 Gamma rays have high penetration power thus can be used after packaging  Leaves no chemical residue

 Administration of precise dosage and uniform dosage distribution

 Immediate availability of the media after sterilization

 Exposure time is less thus can be used for larger quantity

Disadvantages:

 This method is a more costly alternative to heat sterilization

Requires highly specialized equipment

 The process cannot be stopped once started

 The radiations are harmful to the workers

Applications: this method can be used for sterilization of

 Plastic syringes, hypodermic needles, scalpels, surgical blades and adhesive materials.

 Bones and tissue transplant, plastic tubing, catheters and sutures.
