Question

Quizplus · Accepted Answer

Pharmaceutical products are typically sterilized by ionizing radiation, such as gamma radiation or electron-beam radiation. This method effectively kills microbial contaminants without the need for heat, which can damage heat-sensitive products. Ultraviolet radiation, ozone gas, and chlorine gas are generally not effective for sterilizing pharmaceutical products. Freezing can help to preserve pharmaceutical products, but it does not provide sterilization.
