Background

The term 'Background' can be applied to either natural 'Background Radiation', or anywhere where a measurement of Ionising Radiation is required. In analytical Contamination and Radiation measurements it is usual to subtract the background count from the source counts of interest.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution
