All radionuclides, natural and man-made, contained in the environment have radiobiological significance because they are transferred to the food chain, constituting a direct route for internal exposure of population. Consequently, the checking of the natural and artificial concentration levels in foodstuff is important to evaluate abnormalities and exposition doses. In particular, milk is considered as one of the basic food items recommended by international organizations to assess the exposure as well as to implement protective actions on foodstuff consumption restrictions. Therefore, the build up of baselines of natural and anthropogenic concentration of radioisotopes in milk represents an essential issue. Several studies have been carried out regarding the radionuclide contents in milk all around. Here, the measured worldwide natural and anthropogenic nuclide activities in milk sampled reported in the literature since 1983 are compiled and compared. The disclosed annual committed effective dose for the member of public is contrasted with the international recommended annual dose limits.
