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 cps = 1,000 mrem
1 mrem = 0.001 cps
例子:
将15 每秒计数转换为搅拌：
15 cps = 15,000 mrem
| 每秒计数 | 搅拌 |
|---|---|
| 0.01 cps | 10 mrem |
| 0.1 cps | 100 mrem |
| 1 cps | 1,000 mrem |
| 2 cps | 2,000 mrem |
| 3 cps | 3,000 mrem |
| 5 cps | 5,000 mrem |
| 10 cps | 10,000 mrem |
| 20 cps | 20,000 mrem |
| 30 cps | 30,000 mrem |
| 40 cps | 40,000 mrem |
| 50 cps | 50,000 mrem |
| 60 cps | 60,000 mrem |
| 70 cps | 70,000 mrem |
| 80 cps | 80,000 mrem |
| 90 cps | 90,000 mrem |
| 100 cps | 100,000 mrem |
| 250 cps | 250,000 mrem |
| 500 cps | 500,000 mrem |
| 750 cps | 750,000 mrem |
| 1000 cps | 1,000,000 mrem |
| 10000 cps | 10,000,000 mrem |
| 100000 cps | 100,000,000 mrem |
