Activity concentration

from Wikipedia, the free encyclopedia

The activity concentration is a physical quantity that the activity of a radionuclide in the ratio to the volume in which the radionuclide is distributed sets. The activity concentration in Becquerel per cubic meter (Bq / m 3 ) indicated .

The activity concentration is mainly determined when measuring radon in order to be able to draw conclusions about the potential alpha energy of the air . The activity concentration is also used to determine the limit values ​​in drinking water .

A limit value of 100 Bq / l (Becquerel per liter ) was set for tritium in the EC Directive 98/83 / EC .
