What percentage of background radiation in the UK is made up of the radiation from cosmic rays?

What is a dosimeter?

The nucleus of a radioactive substance is [blank_start]unstable[blank_end], which means in can easily change or [blank_start]decay[blank_end]. When [blank_start]decay[blank_end] occurs, radiation is [blank_start]emitted[blank_end] which causes the nucleus to lose [blank_start]energy[blank_end] and become more [blank_start]stable[blank_end]. You cannot predict when a nucleus will [blank_start]decay[blank_end] - it is a random process.
