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 β = 0 C/kg
1 C/kg = 3,876 β
例子:
将15 beta颗粒转换为暴露(C/kg):
15 β = 0.004 C/kg
| beta颗粒 | 暴露(C/kg) |
|---|---|
| 0.01 β | 2.5800e-6 C/kg |
| 0.1 β | 2.5800e-5 C/kg |
| 1 β | 0 C/kg |
| 2 β | 0.001 C/kg |
| 3 β | 0.001 C/kg |
| 5 β | 0.001 C/kg |
| 10 β | 0.003 C/kg |
| 20 β | 0.005 C/kg |
| 30 β | 0.008 C/kg |
| 40 β | 0.01 C/kg |
| 50 β | 0.013 C/kg |
| 60 β | 0.015 C/kg |
| 70 β | 0.018 C/kg |
| 80 β | 0.021 C/kg |
| 90 β | 0.023 C/kg |
| 100 β | 0.026 C/kg |
| 250 β | 0.064 C/kg |
| 500 β | 0.129 C/kg |
| 750 β | 0.193 C/kg |
| 1000 β | 0.258 C/kg |
| 10000 β | 2.58 C/kg |
| 100000 β | 25.8 C/kg |
