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 μSv = 1.0000e-6 β
1 β = 1,000,000 μSv
例子:
将15 Microsievert转换为beta颗粒：
15 μSv = 1.5000e-5 β
| Microsievert | beta颗粒 |
|---|---|
| 0.01 μSv | 1.0000e-8 β |
| 0.1 μSv | 1.0000e-7 β |
| 1 μSv | 1.0000e-6 β |
| 2 μSv | 2.0000e-6 β |
| 3 μSv | 3.0000e-6 β |
| 5 μSv | 5.0000e-6 β |
| 10 μSv | 1.0000e-5 β |
| 20 μSv | 2.0000e-5 β |
| 30 μSv | 3.0000e-5 β |
| 40 μSv | 4.0000e-5 β |
| 50 μSv | 5.0000e-5 β |
| 60 μSv | 6.0000e-5 β |
| 70 μSv | 7.0000e-5 β |
| 80 μSv | 8.0000e-5 β |
| 90 μSv | 9.0000e-5 β |
| 100 μSv | 1.0000e-4 β |
| 250 μSv | 0 β |
| 500 μSv | 0.001 β |
| 750 μSv | 0.001 β |
| 1000 μSv | 0.001 β |
| 10000 μSv | 0.01 β |
| 100000 μSv | 0.1 β |
