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)

The analytical results obtained and the advantages and disad~
vantages of neutron activation and of conventional equipment
toated are considered. Installation costa for various seutton
activation equipment are Indicated and the tvel price of one
oxygen determination by neutron activation and by conventional
Toeans was calculated ag a function of the number of determ!nations performed. I wag concluded that neutron activation

enable the steel makers to choose the deoxidstion means to be
