US EPA Limits of Radioactive Isotopes:

EPA has established a maximum contaminant level of 4 millirem per year for beta particle and photon radioactivity from man-made radionuclide’s in drinking water.

Iodine-131 = 3piC/L (0.11 Bq/L)
Cesium-137 = 200 picocuries per liter (7.41 Bq/L)
Stronium-90 = 8 picocuries per liter. (0.30 Bq/L)
Technetium-99 = 900 picocuries per liter (33.3 Bq/L)
Tritium = 20,000 picocuries per liter (741 Bq/L)
Uranium-238 = 30 µg/L (micrograms/liter)
Iodine-129 = 3 picocuries per liter (0.11 Bq/L)
Milk = 170 Bq/kg (of iodine-131)
