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 n/cm²/s = 1 t½
1 t½ = 1 n/cm²/s
例子:
将15 中子通量转换为半衰期:
15 n/cm²/s = 15 t½
| 中子通量 | 半衰期 |
|---|---|
| 0.01 n/cm²/s | 0.01 t½ |
| 0.1 n/cm²/s | 0.1 t½ |
| 1 n/cm²/s | 1 t½ |
| 2 n/cm²/s | 2 t½ |
| 3 n/cm²/s | 3 t½ |
| 5 n/cm²/s | 5 t½ |
| 10 n/cm²/s | 10 t½ |
| 20 n/cm²/s | 20 t½ |
| 30 n/cm²/s | 30 t½ |
| 40 n/cm²/s | 40 t½ |
| 50 n/cm²/s | 50 t½ |
| 60 n/cm²/s | 60 t½ |
| 70 n/cm²/s | 70 t½ |
| 80 n/cm²/s | 80 t½ |
| 90 n/cm²/s | 90 t½ |
| 100 n/cm²/s | 100 t½ |
| 250 n/cm²/s | 250 t½ |
| 500 n/cm²/s | 500 t½ |
| 750 n/cm²/s | 750 t½ |
| 1000 n/cm²/s | 1,000 t½ |
| 10000 n/cm²/s | 10,000 t½ |
| 100000 n/cm²/s | 100,000 t½ |
