放射能は、不安定な原子核が放射によってエネルギーを失うプロセスです。Beckerels（BQ）で測定されます。
1 mrem = 1,000,000 nGy
1 nGy = 1.0000e-6 mrem
例:
15 mlyをナノグレイに変換します。
15 mrem = 15,000,000 nGy
| mly | ナノグレイ |
|---|---|
| 0.01 mrem | 10,000 nGy |
| 0.1 mrem | 100,000 nGy |
| 1 mrem | 1,000,000 nGy |
| 2 mrem | 2,000,000 nGy |
| 3 mrem | 3,000,000 nGy |

| 10 mrem | 10,000,000 nGy |
| 20 mrem | 20,000,000 nGy |
| 30 mrem | 30,000,000 nGy |
| 40 mrem | 40,000,000 nGy |
| 50 mrem | 50,000,000 nGy |
| 60 mrem | 60,000,000 nGy |
| 70 mrem | 70,000,000 nGy |
