Final answer:
Patients undergoing brachytherapy should minimize time in the radiation environment, keep distance from the radiation source, and use shielding.
Step-by-step explanation:
Patients undergoing brachytherapy should be taught the following precautions and self-care:
- Minimize time in the radiation environment: Spending less time in the radiation environment will result in less exposure to radiation.
- Keep distance from the radiation source: The intensity of radiation decreases exponentially with distance, so it is important to stay as far away from the radiation source as possible.
- Use shielding: Putting shielding between oneself and the radiation source will reduce exposure. The more shielding, the better.
