Answer to Question 1

ANS: C
The supplies are placed into a chamber, and a strong vacuum is created. A solution of water and 58 hydrogen peroxide is vaporized by radiofrequency energy to create a pink glowing reactive plasma. The reactive particles sterilize by heat and moisture in about an hour.

Answer to Question 2

ANS: B
The principal sources of ionizing radiation are beta particles and gamma rays; irradiation can be used to sterilize heat- and moisture-sensitive items. Cobalt-60 is a radioactive isotope capable of disintegrating to produce gamma rays and is the most commonly used source for irradiation sterilization. Irradiation can be used to sterilize heat- and moisture-sensitive items because the rays have a very low temperature effect on materials and because the process is dry.
