La radioactivité est le processus par lequel un noyau atomique instable perd de l'énergie par rayonnement.Il est mesuré en Becquerels (BQ).
1 t½ = 1,000 mrem
1 mrem = 0.001 t½
Exemple:
Convertir 15 Demi-vie en Male:
15 t½ = 15,000 mrem
| Demi-vie | Male |
|---|---|
| 0.01 t½ | 10 mrem |
| 0.1 t½ | 100 mrem |
| 1 t½ | 1,000 mrem |
| 2 t½ | 2,000 mrem |
| 3 t½ | 3,000 mrem |
| 5 t½ | 5,000 mrem |
| 10 t½ | 10,000 mrem |
| 20 t½ | 20,000 mrem |
| 30 t½ | 30,000 mrem |
| 40 t½ | 40,000 mrem |
| 50 t½ | 50,000 mrem |
| 60 t½ | 60,000 mrem |
| 70 t½ | 70,000 mrem |
| 80 t½ | 80,000 mrem |
| 90 t½ | 90,000 mrem |
| 100 t½ | 100,000 mrem |
| 250 t½ | 250,000 mrem |
| 500 t½ | 500,000 mrem |
| 750 t½ | 750,000 mrem |
| 1000 t½ | 1,000,000 mrem |
| 10000 t½ | 10,000,000 mrem |
| 100000 t½ | 100,000,000 mrem |
