Potassium Sulfate (temp. unavailable)

​​​The IAEA-RGK-1 material is produced from high purity (99.8%) potassium sulphate supplied by the Merck Company. The potassium property value and its uncertainty were obtained from repeated measurements performed at the IAEA Laboratories Seibersdorf and the results confirmed the value certified by Merck. The upper limits for the uranium and thorium property values were estimated by the IAEA  Laboratories Seibersdorf using fluorimetry and activation analysis, respectively.
