How is radioactivity used in sterilization?

Radiation kills germs that can cause disease and neutralizes other harmful organisms. Sterilization with ionizing radiation inactivates microorganisms very efficiently and, when used for product wrapping, ensures that healthcare products are safe and can be relied upon.

Why is Cobalt 60 used for sterilization?

The gamma irradiation process uses Cobalt 60 radiation to kill microorganisms on a variety of different products in a specially designed cell. Gamma radiation is generated by the decay of the radioisotope Cobalt 60, with the resultant high energy photons being an effective sterilant.

Why is gamma radiation used for sterilisation?

Gamma irradiation is a physical/chemical means of sterilization, because it kills bacteria by breaking down bacterial DNA, inhibiting bacterial division. Energy of gamma rays passes through the equipment, disrupting the pathogens that cause contamination.

What is phosphorus 32 used for?

A radioactive form of the element phosphorus. It is used in the laboratory to label DNA and proteins. It has also been used to treat a blood disorder called polycythemia vera and certain types of leukemia, but it is not commonly used anymore.

Can gamma rays be used for sterilization?

During sterilization, gamma rays efficiently eliminate microorganisms from the medical devices and tissue allografts, but also significantly change molecular structure of irradiated products, particularly fragile biologics such as cytokines, chemokines and growth factors.

Which radiation is used to sterilize surgical instruments?

gamma rays
Gamma irradiation is a physical/chemical means of sterilization, because it kills bacteria by breaking down bacterial DNA, inhibiting bacterial division. Energy of gamma rays passes through the equipment, disrupting the pathogens that cause contamination.

How is cobalt-60 used?

Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.

What chemical is used for sterilization?

Chemical sterilization involves the utilization of certain chemicals so as to cause microbial termination. For this, the most used materials are chlorine, formaldehyde, glutaraldehyde, quaternary ammonium salts, and ETO.

What is calcium 47 used for in medicine?

Calcium-47 is used in medicine to investigate bone metabolism problems or to diagnose calcium disorders. It is also used in the biomedical research of animals to study the cellular body function and the formation of bones in mammals.
