U-Th-Pb analyses of soil from the Sea of Fertility.Analyses have been made of lead, uranium, and thorium in two soil samples from the Luna 16 mission. Lead was found to be distinctly radiogenic, but significantly less radiogenic than other lunar soils. The Th/U ratio was found to be 3.8, and the uranium concentration was the lowest so far found for lunar soils.
