⚛️ Factors That Affect Background Radiation Dose
| Factor | Effect on dose | Example |
|---|---|---|
| Location (rock type) | Higher on granite; lower on clay | Cornwall ~5 mSv/yr vs UK average 2.7 mSv/yr |
| Altitude | Higher altitude = more cosmic rays | Airline pilots receive ~2× average cosmic ray dose |
| Occupation | Some jobs increase exposure | Nuclear industry workers, radiographers |
| Building materials | Granite/stone buildings emit more gamma | Old granite church vs modern brick house |
| Medical procedures | CT scans add significant dose | Chest X-ray ~0.02 mSv; CT scan ~8 mSv |
