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 = 0 C/kg
1 C/kg = 3,876 n/cm²/s
例子:
将15 中子通量转换为暴露（C/kg）：
15 n/cm²/s = 0.004 C/kg
| 中子通量 | 暴露（C/kg） |
|---|---|
| 0.01 n/cm²/s | 2.5800e-6 C/kg |
| 0.1 n/cm²/s | 2.5800e-5 C/kg |
| 1 n/cm²/s | 0 C/kg |
| 2 n/cm²/s | 0.001 C/kg |
| 3 n/cm²/s | 0.001 C/kg |
| 5 n/cm²/s | 0.001 C/kg |
| 10 n/cm²/s | 0.003 C/kg |
| 20 n/cm²/s | 0.005 C/kg |
| 30 n/cm²/s | 0.008 C/kg |
| 40 n/cm²/s | 0.01 C/kg |
| 50 n/cm²/s | 0.013 C/kg |
| 60 n/cm²/s | 0.015 C/kg |
| 70 n/cm²/s | 0.018 C/kg |
| 80 n/cm²/s | 0.021 C/kg |
| 90 n/cm²/s | 0.023 C/kg |
| 100 n/cm²/s | 0.026 C/kg |
| 250 n/cm²/s | 0.064 C/kg |
| 500 n/cm²/s | 0.129 C/kg |
| 750 n/cm²/s | 0.193 C/kg |
| 1000 n/cm²/s | 0.258 C/kg |
