When is the risk for nurses to be exposed to radiation highest during treatment?

The risk for nurses to be exposed to radiation is highest during treatment without precautions because this is the time when the radiation is actively being delivered to the patient. During the actual treatment phase, the equipment is emitting radiation, and if proper safety measures or protective gear are not utilized, the likelihood of accidental exposure increases significantly.

In contrast, while setting up the equipment, nurses can take precautions to minimize exposure. During patient education sessions, there is typically no radiation in use, and after treatment is completed, the radiation levels would have significantly decreased, further reducing the risk of exposure. Therefore, understanding the timing of radiation delivery and implementing the appropriate safety precautions is crucial for minimizing exposure risks in nursing practice.
