Atoms which have unstable nuclei are radioactive and are called radioisotopes or radionuclides. The change that an unstable nucleus undergoes is called disintegration or decay. When unstable nuclei ...

However, apparently inhaling or ingesting radioactive glass dust can be a problem. Alpha particles can’t go very far through your skin. But once inside your body, they can be hazardous.

This is because the particles or rays become more spread out. The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways.

The Geiger counter kept clicking, sensing radioactivity. It was coming from the aluminium foil, which had absorbed alpha particles from the polonium and become artificially radioactive.

JON CHASE:'Gamma radiation is pure energy, 'but alpha and beta radiation exist in forms of subatomic particles. 'In this case we are looking at the effect of alpha particles. JON CHASE:'The ...

The main radiation emitted by isotopes of uranium is alpha particles (helium nuclei). The range of these alpha particles in air is of the order of one centimetre, while in the case of tissue, they can ...
