| 1. | A triply ionised N-14 atom it pretty unlikely too.
|
| 2. | This ionised region lies in front of a denser molecular cloud.
|
| 3. | As temperature increases, a larger fraction of the bulk ionised.
|
| 4. | The hazard from contamination is the emission of ionising radiation.
|
| 5. | As gamma rays are ionising radiation, they can kill living cells.
|
| 6. | Ionising radiation occurs naturally but can also be artificially created.
|
| 7. | The initially electroneutral acceptor becomes negatively charged ( ionised ).
|
| 8. | The initially electroneutral donor becomes positively charged ( ionised ).
|
| 9. | Later this was shown to be ionised nitrogen and oxygen.
|
| 10. | Ionising radiation kills cells indirectly by creating reactive free radicals.
