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