was similar to cow milk in that the CaKNa resin removed less than that removed from milk which had strontium added to 1. In fact only 35 per cent
of the strontium was removed, less than could be one Gom cowmilk. This

It appears that strontium and cesium removal from milk is possible. More
work must be done before the process can be placed on a commercial basis.
