- Uses of Radiation
- Smoke alarms.
- Contain weak source of alpha radiation.
- Not beta or gamma as alpha radiation is more ionizing and stopped by a few cm of air.
- Long half-life so don't have to change often.
- Smoke interacts with ions produced by alpha particles. Ionization reduced.
- Less current flowing.
- Alarm sounds.
- Contain weak source of alpha radiation.
- Cracks in welding.
- Gamma rays.
- Not alpha as low penetration.
- Not beta as reading wouldn't be as clear.
- Short half-life so not dangerous to workers.
- Gamma source and photographic film either side.
- Like an X-ray.
- Gamma rays.
- Paper thickness.
- Beta radiation.
- Gamma wouldn't be effective as wont detect thickness. Alpha is stopped by paper so won't work.
- Long half-life so doesn't need replacing often.
- Radioactive source and Geiger Muller tube either side.
- Close rollers if too thick, open if to thin.
- Beta radiation.
- Smoke alarms.
