What can decontamination help achieve concerning radiation exposure?

Decontamination is an essential process in managing radiation exposure, particularly in environments where radioactive materials may be present. The correct choice highlights its primary purpose: to remove surface contamination. This is crucial because radioactive contaminants can attach to skin, clothing, and surfaces, leading to potential radiation exposure.

By effectively removing these contaminants, decontamination reduces the amount of radioactive material that can emit radiation and pose a risk to health. This reduction directly contributes to lowering an individual's overall radiation dose and helps mitigate the potential adverse effects associated with radioactive exposure. Therefore, decontamination is a vital step in protecting public health and safety in the event of contamination incidents.

Options suggesting that decontamination increases radiation levels, lowers temperature, or has no effect at all do not align with the established understanding and practices regarding radiation safety and contamination management.
