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 α = 1,000,000 μGy
1 μGy = 1.0000e-6 α
例子:
将15 α颗粒转换为微流：
15 α = 15,000,000 μGy
| α颗粒 | 微流 |
|---|---|
| 0.01 α | 10,000 μGy |
| 0.1 α | 100,000 μGy |
| 1 α | 1,000,000 μGy |
| 2 α | 2,000,000 μGy |
| 3 α | 3,000,000 μGy |
| 5 α | 5,000,000 μGy |
| 10 α | 10,000,000 μGy |
| 20 α | 20,000,000 μGy |
| 30 α | 30,000,000 μGy |
| 40 α | 40,000,000 μGy |
| 50 α | 50,000,000 μGy |
| 60 α | 60,000,000 μGy |
| 70 α | 70,000,000 μGy |
| 80 α | 80,000,000 μGy |
| 90 α | 90,000,000 μGy |
| 100 α | 100,000,000 μGy |
| 250 α | 250,000,000 μGy |
| 500 α | 500,000,000 μGy |
| 750 α | 750,000,000 μGy |
| 1000 α | 1,000,000,000 μGy |
| 10000 α | 10,000,000,000 μGy |
| 100000 α | 100,000,000,000 μGy |
