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 mSv = 0.001 n/cm²/s
1 n/cm²/s = 1,000 mSv
例子:
将15 毫米转换为中子通量：
15 mSv = 0.015 n/cm²/s
| 毫米 | 中子通量 |
|---|---|
| 0.01 mSv | 1.0000e-5 n/cm²/s |
| 0.1 mSv | 0 n/cm²/s |
| 1 mSv | 0.001 n/cm²/s |
| 2 mSv | 0.002 n/cm²/s |
| 3 mSv | 0.003 n/cm²/s |
| 5 mSv | 0.005 n/cm²/s |
| 10 mSv | 0.01 n/cm²/s |
| 20 mSv | 0.02 n/cm²/s |
| 30 mSv | 0.03 n/cm²/s |
| 40 mSv | 0.04 n/cm²/s |
| 50 mSv | 0.05 n/cm²/s |
| 60 mSv | 0.06 n/cm²/s |
| 70 mSv | 0.07 n/cm²/s |
| 80 mSv | 0.08 n/cm²/s |
| 90 mSv | 0.09 n/cm²/s |
| 100 mSv | 0.1 n/cm²/s |
| 250 mSv | 0.25 n/cm²/s |
| 500 mSv | 0.5 n/cm²/s |
| 750 mSv | 0.75 n/cm²/s |
| 1000 mSv | 1 n/cm²/s |
| 10000 mSv | 10 n/cm²/s |
| 100000 mSv | 100 n/cm²/s |
