“…The relatively short half-life of 38 Cl means that sensitivity will be lost if the separation procedure takes more than ∼1 h. Therefore, the aim of the work was to develop a radiochemical method that would dissolve the sample and separate the Cl as rapidly as possible, and certainly in no longer than 1 h, including a method of measuring the recovery of Cl for each determination. Radiochemical separation will improve the detection of Cl considerably, − and the aim was to reduce to detection limit to below 1 mg/kg.…”

Chlorine is usually present at low concentrations in reactor materials and thermal neutron activation of (35)Cl produces (36)Cl, which has a long half-life and is a radionuclide of significance in nuclear waste disposal. This paper describes a radiochemical method that has been developed to measure low concentrations of Cl in reactor stainless steels, so that the amount of (36)Cl in radioactive wastes can be estimated. The method is based on the irradiation of a 1 g sample in a thermal neutron flux of 10(16) n m(-)(2) s(-)(1), followed by dissolution in HNO(3) with the addition of stable KCl carrier/tracer. The Cl is precipitated as AgCl, and the recovery is measured gravimetrically. The (38)Cl, which has a half-life of 37 min, is measured with γ-ray spectrometry. The entire process, from irradiation to the end of counting, takes ∼1.5 h. The recovery is near-quantitative, and the detection limit for Cl in most stainless steels is below 1 mg/kg.

“…Brooksbank, Leddicotte, and Reynolds applied neutron-activation methods to the problem of determining trace amounts of tungsten, chlorine, vanadium, nickel, copper, manganese, and silicon in titanium metal and its compounds (28). The method is also useful for qualitative purposes in identifying other trace elements present.…”
