[en] The development and testing of a practical field method for the collection of radioiodine from milk is reported. The technique is simple, rapid and relatively inexpensive to perform and yields a good iodine collection efficiency. The batch method involves adding a 250-ml volume of Dowex 1-X8 anion exchange resin to 3.5 liters of milk, mixing at a rate of 30 rotations per minute for three minutes, separating the resin and milk by pouring the mixture through a wire-screened canister, and rinsing the resin with 200-ml of distilled water. Advantages of the procedure include: minimal equipment and personnel training; an inexpensive industrial-grade resin; a total of ten minutes to complete; and an adaptability of the wire-screened canister to different geometries for direct counting. Additionally, the total collection efficiency of 81 +- 6% is relatively independent of temperature, iodide concentration, mixing rate and mixing time
