Lab 77 Nuclear Radiation Detection
... As nuclear radiation travels away from its source, its strength decreases. This weakening is inversely related to the square of the distance from the radiation source. This is known as the inverse square law. All forms of radiation follow this law. Therefore, unless you know where a radiation source ...

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.
