Sandalls, F. a. {Atomio Energy Research Fatablishment, Harwell (Eagland)), Mar. 1967, 12p, Dep. CFSTI. UK 1s, #d. A rapid and sensitive method la described. A 10-ml sample of urfne with added sulphate carrier la oxidized with Benedict's re- agent and 8 precipitated as berlum wulphate. An overall recovery af 95% ts obtained, and the counting efficiency is 75% with a Packard Tricarh 3214 counter. Tha minimum level of detection corresponds to epproximately 340 pCI/1400 ml of urine, which |s lower than the Investigation level by «factor of about £0/, (auth) E766 {AERE-A-8406) THE DETERMINATION OF RADIO- IODINE IN HARWELL EFFLUENT.
