Monitoring of cesium-137 and strontium-90 in consumption milk is a sub-programme of a national monitoring program regarding environmental radiation in Sweden. The sub-programme has been ongoing since 1955. In the event of increased deposition of radionuclides, e.g. after a nuclear accident, transfer to cow milk is a quick process. The concentration in milk is therefore a good indicator of any changes of the levels of radionuclides in the area. Monitoring is performed at 5 dairies: Umeå, Sundsvall, Kallhäll, Jönköping and Malmö, where milk is sampled 4 times per year.

Cs-137 and K-40 is measured at all 5 dairies, whereas Sr-90 is measured at Umeå and Kallhäll only.

The Swedish national monitoring program regarding environmental radiation consists of the following sub-programmes: particles in air, surface water, drinking water, dairy milk, mixed food, wild game (moose), marine sediments, marine water, marine fish, whole human body, and gamma radiation on ground level.
