Description

This document is the report from a November 1948 meeting at Mound Laboratory on the measurement of the density of metallic polonium. Four determinations of the density of Polonium at 25 degrees C have been made. These values are 8.69 gm/cc, 9,34 gm/cc (twice) and 9.20 gm/cc. The probable error was 2%. The material used in the first determination was not subjected to a preliminary purification, which makes the value obtained doubtful. In this instance, production foils were used without a separation from their more volatile constituents. The difference in the reported value from that which appears in the Ad … continued below

The material used in the first determination was not subjected to a preliminary purification, which makes the value obtained doubtful. In this instance, production foils were used without a separation from their more volatile constituents. The difference in the reported value from that which appears in the Ad Interim Report is due to a recalculation based on the latest information on the physical constants of polonium. The value of using pure material and knowing the physical properties of polonium are clearly indicated.
