| 11. | Today's tritium concentration is instead governed by nuclear reactions and cosmic rays.
|
| 12. | To detect such anomalies one may make use of the nuclear reaction
|
| 13. | The rods are used to control and stop a nuclear reaction.
|
| 14. | In addition, about 3 % of it is fission products from nuclear reactions.
|
| 15. | It was a very feeble effect, but the first nuclear reactions were feeble.
|
| 16. | Fears remain of a possible continued nuclear reaction at the plant.
|
| 17. | The result would be a mini-nuclear reaction that killed tumorous tissue.
|
| 18. | Only nuclear reactions emit enough energy to give a measureable difference in mass.
|
| 19. | Nuclear reactions cannot be realized by chemical reactions such as combustion.
|
| 20. | The experiments are allowed, the department argues, because no nuclear reaction will occur.
