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 dps = 1 β
1 β = 1 dps
例子:
将15 每秒分解转换为beta颗粒：
15 dps = 15 β
| 每秒分解 | beta颗粒 |
|---|---|
| 0.01 dps | 0.01 β |
| 0.1 dps | 0.1 β |
| 1 dps | 1 β |
| 2 dps | 2 β |
| 3 dps | 3 β |
| 5 dps | 5 β |
| 10 dps | 10 β |
| 20 dps | 20 β |
| 30 dps | 30 β |
| 40 dps | 40 β |
| 50 dps | 50 β |
| 60 dps | 60 β |
| 70 dps | 70 β |
| 80 dps | 80 β |
| 90 dps | 90 β |
| 100 dps | 100 β |
| 250 dps | 250 β |
| 500 dps | 500 β |
| 750 dps | 750 β |
| 1000 dps | 1,000 β |
| 10000 dps | 10,000 β |
| 100000 dps | 100,000 β |
