These are the various important things that you should know about gamma radiation sterilization. Gamma irradiation as a sterilizing method is a tried-and-true technique that has been employed in over 50 nations for a variety of purposes since the 1950s. Irradiation is a perfectly safe and clean way of hygienization materials that produces no toxic by-products or causes a temperature increase. Many nations, including the United States, New Zealand, and Australia, have made irradiation a necessary treatment prior to the import of specific foods.

There are numerous companies that perform gamma radiation sterilization. One of the most renowned companies that do gamma sterilization is Symec Engineers. They have a work attitude that encourages creativity, hard effort, professionalism, and the desire to build and develop new solutions in difficult environments.

Gamma irradiation is the carefully regulated exposure of various items to ionizing gamma rays (similar to UV and X-rays) for a specific aim, such as the eradication of bacteria, viruses, pathogens, insects, and other undesired organisms. Gamma rays are a kind of electromagnetic radiation with very short wavelengths that operate as an ionizing source, killing germs and pests. The most frequent source of gamma rays for irradiation processing is the isotope Cobalt-60. The Cobalt-60 is made expressly for irradiation and is contained in specially built double encapsulated Stainless-Steel Pencils that are housed in a carefully developed system that follows rigorous norms and regulations.

When the gamma source is elevated into the irradiation chamber, Cobalt 60 may be securely kept in a pool of water, while the chamber above the pool is encircled by a thick concrete barrier that prevents gamma rays from escaping. A conveyor transports sterilized product into the irradiation chamber after it has been packed and delivered. Because the temperature of the treated product does not rise much, gamma irradiation is classified as a 'Cold Process.' It's also a chemical-free method that's unaffected by temperature, humidity, or pressure.

Now let's understand the flow of the process. At the gamma irradiation processing plant, the goods come on a truck and are unloaded. The product is put into the carrier/tote and transferred into the radiation cell, where it is subjected to the radiation field, according to the specified configurations. To deliver the required dosage, the product is cycled around the radiation source for a set period of time. The items are then unloaded, released, or delivered back to the consumer at the end of the cycle.

Benefits: The most significant benefit of the gamma sterilization procedure is that it is both efficient and effective when utilized appropriately. In certain sectors and for specific purposes, sterilization might take hours, but in others, it can be accomplished in a matter of minutes. Certain items, for example, can be sterilized in a couple of seconds.

Another significant advantage of gamma sterilization is its ability to penetrate deeply into things, making it perfect for cleaning a wide range of products, regardless of density, orientation, or material type. Furthermore, the procedure may be used on items that have already been packed, lowering the danger of contamination following sterilization. This method is applicable to more than simply solid dry commodities; it also works well with frozen things.

Simply put, gamma radiation sterilization can assist assure sterility assurance, offering individuals involved with the treated product or goods peace of mind that what they're wearing, eating, manufacturing, or distributing is safe. It's also quite simple to administer. In actuality, personnel in charge of the gamma sterilization procedure are just obliged to keep track of the dose and exposure duration. As a result, it's quite simple to pick up and use. Products and materials handled as a result of the procedure are not radioactive, contrary to popular belief. Furthermore, there is no detrimental influence on the environment as a result of this technique.

Application: As you might assume, using contaminated medical instruments to perform surgery or treatment on a patient might result in infection and extra difficulties. This is why medical instruments must be thoroughly sanitized before being used. This is becoming increasingly crucial as hospitals deal with PPE shortages as a result of the COVID-19 pandemic's inflow of patients. Gamma irradiation sterilization has an application on various types of products like:

  • Gems

  • Medical equipment

  • Potato and onions

  • Certain packaged goods

  • Cosmetics

  • Pharmaceutical packaging and products

  • Raw materials

  • Certain foods like fruits, vegetables, grains, cereals, pulses

  • Agricultural applications
