Following an incident involving a gamma-ray source, two routes are available for leaving a building. A detector is used to estimate the radiation dose a person would receive in each section of each route.
| Route | Dose in first section | Dose in second section |
|---|---|---|
| A | 0.004 Sv | 1.5 mSv |
| B | 2.0 mSv | 2.5 mSv |
Calculate the total radiation dose for each route. Explain which route should be used to reduce the risk of harm.
