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 mGy = 1,000,000 nSv
1 nSv = 1.0000e-6 mGy
例子:
将15 毫克转换为nanosevert：
15 mGy = 15,000,000 nSv
| 毫克 | nanosevert |
|---|---|
| 0.01 mGy | 10,000 nSv |
| 0.1 mGy | 100,000 nSv |
| 1 mGy | 1,000,000 nSv |
| 2 mGy | 2,000,000 nSv |
| 3 mGy | 3,000,000 nSv |
| 5 mGy | 5,000,000 nSv |
| 10 mGy | 10,000,000 nSv |
| 20 mGy | 20,000,000 nSv |
| 30 mGy | 30,000,000 nSv |
| 40 mGy | 40,000,000 nSv |
| 50 mGy | 50,000,000 nSv |
| 60 mGy | 60,000,000 nSv |
| 70 mGy | 70,000,000 nSv |
| 80 mGy | 80,000,000 nSv |
| 90 mGy | 90,000,000 nSv |
| 100 mGy | 100,000,000 nSv |
| 250 mGy | 250,000,000 nSv |
| 500 mGy | 500,000,000 nSv |
| 750 mGy | 750,000,000 nSv |
| 1000 mGy | 1,000,000,000 nSv |
| 10000 mGy | 10,000,000,000 nSv |
| 100000 mGy | 100,000,000,000 nSv |
