Determination of Strontium-90 in Milk by an Ion Exchange Method
A simple and rapid method was developed for measuring low concentrations of strontium-90 in milk, with an estimated standard deviation of 1 mu mu c per liter in the 1- to 20- mu mu c per liter range. A liter of milk is passed successively through cation exchange resin, to remove the alkaline and alkaline earth ions, and through anion exchange resin, which retains the yttrium-90 daughter of strontium90. The yttrium is eluted with dilute hydrochloric acid, precipitated as the oxalate, and counted in an anti-coincidence beta counter. Good agreement is found between this method and a previously established method. (auth)
