Which of the following is used for quality control of gamma irradiation?

Gamma Irradiation Quality Control

Bacillus pumilus spore strips are commonly used for quality control of gamma irradiation due to their resistance to gamma rays. These biological indicators are crucial in verifying the effectiveness of the sterilization process. Gamma radiation sterilization protocols typically involve the use of biological spore indicators from resilient bacteria.

It is essential to select spore strips that can withstand the irradiation process to ensure that the sterilization is effective. Bacillus pumilus spores are known for their remarkable resistance to gamma rays, making them an ideal choice for monitoring the efficiency of gamma irradiation.

On the other hand, Bacillus subtilis spore strips are used for biological indicator spore tests to determine the efficacy of sterilization protocols, including gamma radiation. These tests help in confirming whether the endospores are terminated by the sterilization process.
