Cs-137 @ 4.1 pCi/l

EPA lumps these gamma and beta emitters together under one collective MCL, so if you’re seeing cesium-137 in your milk or water, the MCL [Maximum Contaminant Level] is 3.0 picocuries per liter; if you’re seeing iodine-131, the MCL is 3.0; if you’re seeing cesium-137 and iodine-131, the MCL is still 3.0. -Forbes.com
