Gamma Radiation Sterilisation
Gamma irradiation is a widely accepted process for sterilisation and bio burden reduction that uses Cobalt-60 as the Gamma source. It is a simple and safe process involving exposure of products to Gamma rays for a predetermined duration so as to impart the desired dose. Gamma rays are short waves of considerable energy that disrupt genetic molecules, like DNA & RNA, and inactivate living microorganisms.
The process is carried out at ambient conditions and the temperature of the product does not increase significantly. This effectively does not alter the physical and sensory quality of products, which is important especially for Healthcare Products, Agriculture Produce and Herbal Extracts & Formulations. Since this is a physical means of sterilisation Gamma irradiation does not leave any residues in the product nor does this induce any radioactivity in the product.
Gamma rays are highly penetrating; thus there are no limitations on the choice of packaging material. This process is a go-to method for sterilisation of APIs, ophthalmic ointments, finished drug formulations, disposable medical devices, packaging components, etc.
Irradiation also finds applications in the Food Industry:
- Reduces the risk of food-borne disease: Food-borne diseases are a growing public health problem. Irradiation helps eliminate pathogens & reduction in bio burden, extend shelf life and add value
- Reduce product spoilage: Irradiation helps in delaying ripening of fruits, sprouting of vegetables and food grains, etc., thereby reducing wastage and helping in food security
- Biosecurity: As this is an approved and accepted phytosanitary treatment that meets quarantine requirements, it assists international trade
MICROTROL uses state-of-the-art Alanine dosimetry system and conventional Ceric Cerous dosimetry system for dose measurement.
MICROTROL currently offers total irradiation solutions, from establishing the sterilisation dose to routine processing (including dose audits), from our Bengaluru and Bawal facilities.
