Which statement regarding irradiation sterilization is true?
a. The principal sources of ionizing radiation are water molecules and heat.
b. Ionizing radiation is the most effective sterilization method.
c. Irradiation cannot sterilize heat- and moisture-sensitive items.
d. Beta 45 is the most commonly used source for irradiation sterilization.
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.
