- Radioactivity safety
- Radiation Harms Living cells
- Radiation molecules enter living cells and collide with molecules
- Collisions cause ionisation which damages or destroys molecules
- Small doses leads to mutation
- Cancerous cells
- Higher doses causes cells to die completely
- Outside the body BETA and GAMMA sources are most dangerous as they can get inside your organs
- Inside the body, ALPHA sources are the most dangerous as they focus on particular places.
- Radiation molecules enter living cells and collide with molecules
- Safety
- During experiments
- Radioactive substances should not be used for a long time
- Don't ever touch the radioactive source
- Use tongs
- Hold the source at arms length and point it away from your body
- Keep sources in a lead box
- During experiments
- Radiation Harms Living cells
