Radiation and Filtration

For Ionizing Radiation, Nonionizing Radiation, and Filtration, describe the following:
a. types
b. common uses
c. specific effects on microbes, is it microbicidal?
d. when not to use

Solution Preview

Ionizing radiation:
a. Types: this is a method of controlling microbial growth. Ionizing radiation consist of gamma rays and X-rays. They are powerful and can penetrate the DNA to cause breakage of the DNA (1). It also contains electromagnetic radiation that produces electrons, hydroxyl radicals, and hydride radicals that damage DNA and protein of the cells (2).

b. Common uses: They are used to regulate and control the growth of microorganisms in drugs, food, vaccines, medical plastics, surgical gloves, skin tissue grafts, and bone grafts (1). They are able to penetrate and sterilize materials even in outer wrappings (1).

c. Microbicidal? Yes, since ionizing radiation can penetrate the DNA of bacteria and ...

Solution Summary

Ionizing radiation is a method of controlling microbial growth. Ionizing radiation consist of gamma rays and X-rays. They are powerful and can penetrate the DNA to cause breakage of the DNA (1). It also contains electromagnetic radiation that produces electrons, hydroxyl radicals, and hydride radicals that damage DNA and protein of the cells (2).
The Common uses is to regulate and control the growth of microorganisms in drugs, food, vaccines, medical plastics, surgical gloves, skin tissue grafts, and bone grafts (1). They are able to penetrate and sterilize materials even in outer wrappings (1). It is Microbicidal since ionizing radiation can penetrate the DNA of bacteria and break the DNA, causing the bacteria to die completely (1). When not in use, the Worker can be exposed to the ionizing radiation so it poses a risk of exposure to those to work with ionizing radiation.
