Treated liquid wastes containing traces of plutonium and americium are released into Mortandad Canyon, within the site of Los Alamos National Laboratory, NM. The wastes infiltrate a small aquifer within the canyon. Although laboratory studies have pr

A method has been developed to isolate quantitatively the actinide elements (as a group) from urine samples and to produce near massless electrodeposits suitable for high-resolution α-spectrometry. The actinides are concentrated from the bulk urine

The concentration of plutonium and its oxidation state distribution have been measured as a function of depth at three locations in the North Pacific Ocean. Concentration profiles were similar to those observed in the same area during 1974 with prima

Adsorption of actinide elements to calcium carbonate in waters of moderate to high carbonate concentration has been shown to be dependent on the oxidation state. This property has been exploited for distinguishing the (III) and (IV) oxidation states

Distribution coefficients (K D ) were measured by a batch technique for sorption of americium-243 and curium-244 to Lake Michigan sediment from four different natural surface waters. The dependences of K D values on pH and on the concentrations of na

The sediment-depth distributions of 238Pu, 239,240Pu, 241Am and 137Cs have been measured in a sediment core from the Saguenay Fjord, Quebec, Canada, which has been dated to better than 1-yr. resolution over the past 100 yr. using 210Pb. The historica
