Final answer:
During radiation treatments, it is important for patients to lie still and breathe normally.
Step-by-step explanation:
The correct answer is C. Lie still and breathe normally.
During radiation treatments, it is important for patients to lie still and breathe normally. This helps ensure accurate delivery of radiation to the intended area and minimizes the exposure of surrounding healthy tissues. By lying still, patients can also help maintain the proper alignment of the treatment area with the radiation beam.
Other radiation protection measures include keeping minimum possible time in the radiation environment, keeping as much distance from the radiation source as possible, and keeping shielding between you and the source of radiation.
