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