| Although this noble gas is relatively inert chemically, it is still considered a health hazard because it gives off alpha particle radiation. |
| The disintegration of the nucleus produces one alpha particle. |
| An alpha particle is a heavy nucleon, which is actually the nucleus of a helium atom. |
| Thus uranium in the sixth group loses an alpha particle and the product UX1 falls in the fourth group. |
| The neutron is a better hammer than the alpha particle for smashing nuclei. |
| At Chooz A, I visited a work area with an alpha particle radiological hazard. |
