When studying radioactivity, it's really important to follow safety rules. This helps keep you safe from harmful radiation. Here are some key safety tips:

1. Wear Safety Gear

• Lab Coats: Always wear lab coats to protect your skin and clothes.
• Gloves: Use gloves when you handle any radioactive materials.
• Safety Goggles: Wear safety goggles to protect your eyes from radiation and splashes.

2. Limit How Long You Stay Close

• Try to spend less time near radioactive sources. The farther away you are, the less radiation you get. For example, if you double your distance from the source, the exposure drops down to one-fourth!

3. Stay at a Safe Distance

• Keep at least 2 meters away from radioactive materials unless you really need to be close.
• Use tools like tongs or remote devices to avoid getting too close.

4. Use Shields

• Use the right shields depending on the type of radiation:
  • Alpha Particles: A sheet of paper or your skin can stop them.
  • Beta Particles: You need plastic or glass to block these.
  • Gamma Rays: These are very strong and need lead or thick concrete to protect you.

5. Check Radiation Levels

• Use tools like Geiger counters to keep an eye on radiation levels. This helps make sure they stay safe. Radiation exposure is usually measured in sieverts (Sv). For most people, the safe yearly limit is about 1 mSv, while workers in radiation jobs can have up to 20 mSv.

6. Get Rid of Waste the Right Way

• Make sure to dispose of radioactive waste according to local rules. This helps prevent pollution and keeps the environment safe.
