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 rad = 1 rad
1 rad = 1 rad
例子:
将15 rad转换为rad：
15 rad = 15 rad
| rad | rad |
|---|---|
| 0.01 rad | 0.01 rad |
| 0.1 rad | 0.1 rad |
| 1 rad | 1 rad |
| 2 rad | 2 rad |
| 3 rad | 3 rad |
| 5 rad | 5 rad |
| 10 rad | 10 rad |
| 20 rad | 20 rad |
| 30 rad | 30 rad |
| 40 rad | 40 rad |
| 50 rad | 50 rad |
| 60 rad | 60 rad |
| 70 rad | 70 rad |
| 80 rad | 80 rad |
| 90 rad | 90 rad |
| 100 rad | 100 rad |
| 250 rad | 250 rad |
| 500 rad | 500 rad |
| 750 rad | 750 rad |
| 1000 rad | 1,000 rad |
