When doctors use radioactive materials in medicine, they need to think about safety in a few important ways:

1. Radiation Exposure: Both patients and healthcare workers might be around harmful levels of radiation.

2. Waste Management: Getting rid of radioactive waste can be very dangerous for health.

3. Accidental Contamination: If equipment breaks, it can cause contamination and more exposure to radiation.

Solutions:

• Follow strict rules for handling radioactive materials.
• Use barriers and keep a safe distance to reduce exposure.
• Provide regular training for staff so they know safety procedures well.
