Radiation Protection Glossary

With respect to Radiation Protection , a plane source describes a source of Ionising Radiation which can physically be represented by a thin flat area (e.g area of contaminated). Sources are often represented in this way when calculations of estimates of exposures are required. In many cases the plane source will only represent an approximation of the real source, but this is usually adequate if sufficient factors of safety are built into the model. Other useful descriptions of sources include the Point Source , the Volume Source , the Line Source and the Immersion (cloud) Source .
