Wikipedia Meaning and Definition on 'Ionising'
Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This is often confused with dissociation (chemistry).
The process works slightly differently depending on whether an ion with a positive or a negative electric charge is being produced. A positively-charged ion is produced when an electron bonded to an atom (or molecule) absorbs enough energy to escape from the electric potential barrier that originally confined it, thus breaking the bond and freeing it to move. The amount of energy required is called the ionization potential. A negatively-charged ion is produced when a free electron collides with an atom and is subsequently caught inside the electric potential barrier, releasing any excess energy.[See more about Ionising at Dictionary 3.0 Encyclopedia]

- Airline pilots, crew face increased risk of skin cancer
New York, Sep 4 (IANS) Pilots and air crew face twice the risk of the deadly skin cancer Melanoma compared with the general population, says a study. This higher risk may be due to the increased exposure to ionising radiation and ultraviolet (UV) radiation at higher altitudes, the researchers said. "At 9,000 metres, where most commercial aircraft fly, the UV Read more on this news related to 'Ionising'
