🏭 Industrial Uses — Summary
| Use | Radiation | How it works |
|---|---|---|
| Smoke detectors | Alpha | Alpha ionises air; smoke absorbs alpha, current drops, alarm sounds |
| Paper thickness | Beta | Beta partially absorbed by paper; detector measures how much passes through |
| Checking welds | Gamma | Gamma passes through metal; cracks show up on detector |
| Sterilising food | Gamma | Kills bacteria without heating; doesn't make food radioactive |
