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 = 1,000 nGy
1 nGy = 0.001 μSv
例子:
将15 Microsievert转换为纳米：
15 μSv = 15,000 nGy
| Microsievert | 纳米 |
|---|---|
| 0.01 μSv | 10 nGy |
| 0.1 μSv | 100 nGy |
| 1 μSv | 1,000 nGy |
| 2 μSv | 2,000 nGy |
| 3 μSv | 3,000 nGy |
| 5 μSv | 5,000 nGy |
| 10 μSv | 10,000 nGy |
| 20 μSv | 20,000 nGy |
| 30 μSv | 30,000 nGy |
| 40 μSv | 40,000 nGy |
| 50 μSv | 50,000 nGy |
| 60 μSv | 60,000 nGy |
| 70 μSv | 70,000 nGy |
| 80 μSv | 80,000 nGy |
| 90 μSv | 90,000 nGy |
| 100 μSv | 100,000 nGy |
| 250 μSv | 250,000 nGy |
| 500 μSv | 500,000 nGy |
| 750 μSv | 750,000 nGy |
| 1000 μSv | 1,000,000 nGy |
| 10000 μSv | 10,000,000 nGy |
| 100000 μSv | 100,000,000 nGy |
