Gamma radiation is a form of ionizing energy
that sterilizes the exterior of a medical device.
Application of the ionizing energy
at 5 kGy results in formation of small pieces of scrap of material forming a "brick-wall" structure (Fig.
When food is irradiated, a concentrated source of short ionizing energy
waves is used.
Irradiation exposes food products to ionizing energy
to reduce or eliminate pathogens such as Salmonella, Campylobacter, E.
Irradiation is a process similar to pasteurization which uses ionizing energy
to eliminate bacteria in food, such as E.
You essentially have an electron generator, and the electrons produce ionizing energy
that kills bacteria.
Through the use of ionizing energy
, irradiation kills food-borne pathogens without changing quality or taste.
The type of radiation used in radiation therapy (x or gamma rays) gives up much of its ionizing energy
at or near the surface of the body, then gradually loses energy as it passes through the body.
The first text dealt with the wholesomeness of food treated with ionizing energy
and this second text looks at applications.
The majority of MDS Nordion irradiators are gamma-based systems, which use cobalt-60 sources producing ionizing energy
to destroy harmful microorganisms.
