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