放射性是不稳定原子核因辐射失去能量的过程。它以Becquerels（BQ）进行测量。
1 n/cm²/s = 1,000 mSv
1 mSv = 0.001 n/cm²/s
例子:
将15 中子通量转换为毫米：
15 n/cm²/s = 15,000 mSv
| 中子通量 | 毫米 |
|---|---|
| 0.01 n/cm²/s | 10 mSv |
| 0.1 n/cm²/s | 100 mSv |
| 1 n/cm²/s | 1,000 mSv |
| 2 n/cm²/s | 2,000 mSv |
| 3 n/cm²/s | 3,000 mSv |
| 5 n/cm²/s | 5,000 mSv |
| 10 n/cm²/s | 10,000 mSv |
| 20 n/cm²/s | 20,000 mSv |
| 30 n/cm²/s | 30,000 mSv |
| 40 n/cm²/s | 40,000 mSv |
| 50 n/cm²/s | 50,000 mSv |
| 60 n/cm²/s | 60,000 mSv |
| 70 n/cm²/s | 70,000 mSv |
| 80 n/cm²/s | 80,000 mSv |
| 90 n/cm²/s | 90,000 mSv |
| 100 n/cm²/s | 100,000 mSv |
| 250 n/cm²/s | 250,000 mSv |
| 500 n/cm²/s | 500,000 mSv |
| 750 n/cm²/s | 750,000 mSv |
| 1000 n/cm²/s | 1,000,000 mSv |
| 10000 n/cm²/s | 10,000,000 mSv |
| 100000 n/cm²/s | 100,000,000 mSv |
