... • When a radium source (held in tongs, and well away from the face) is held close to the cap, without touching it, the leaf is seen to collapse. This is due to the ionization of the air produced by the radiation emitted by the radium, which produces positive ions and negative electrons. If the cap i ...

... • Example: Beta decay process is the decay of iodine- 131 into xenon131 by beta-particle emission • The mass number of the product nucleus is the same as that of the original nucleus ( they are both 131), but its atomic number has increased by 1 (54 instead of 53). This changed in atomic number, and ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
