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 R = 2.5800e-6 C/kg
1 C/kg = 387,600 R
例子:
将15 罗恩根转换为暴露(C/kg):
15 R = 3.8700e-5 C/kg
| 罗恩根 | 暴露(C/kg) |
|---|---|
| 0.01 R | 2.5800e-8 C/kg |
| 0.1 R | 2.5800e-7 C/kg |
| 1 R | 2.5800e-6 C/kg |
| 2 R | 5.1600e-6 C/kg |
| 3 R | 7.7399e-6 C/kg |
| 5 R | 1.2900e-5 C/kg |
| 10 R | 2.5800e-5 C/kg |
| 20 R | 5.1600e-5 C/kg |
| 30 R | 7.7399e-5 C/kg |
| 40 R | 0 C/kg |
| 50 R | 0 C/kg |
| 60 R | 0 C/kg |
| 70 R | 0 C/kg |
| 80 R | 0 C/kg |
| 90 R | 0 C/kg |
| 100 R | 0 C/kg |
| 250 R | 0.001 C/kg |
| 500 R | 0.001 C/kg |
