Analyses of Radionuclides of Biological Interest in Pacific Waters

Nonferrous metallurgy. II. Zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, and tungsten

“…Chromatographic separations preceded the radiochemical determination in papers by Welford and Chiotis (574), Welford, Choitis, and Morse (575) and Breccia and Spalletti (60). The determination of radionuclides including zirconium dissolved in water was the subject of papers by Wood and Richards (588), Chakravarti et al (86) and Bizollon and Moret (45). Osterberg, Pearcy, and Kujala (382) determined zirconium in tissue from a male fin whale.…”

“…McMillan (309) preceded a radiochemical determination of samples from pressurized water loops with group separations using both a cation and an anion exchange resin. Chakravarti et al (86) presented methods for the determination of radionuclides in Pacific waters. Hilton and Reed (199) determined activation products in irradiated steels by using -ray spectrometry and an anion exchange separation with a precision of 2%.…”

Cosmogenic P-32 and P-33 in the atmosphere and aligotrophic ocean and applications to the study of phosphorus cycling

“…Early studies utilizing artificial 3 2 P took advantage of the release of the tracer from the water cooling system of nuclear reactors (Chakravarti, 1964). In a later study 3 2 P was released in a saltmarsh to trace the P cycle in that ecosystem (Pomeroy et al, 1967).…”
