Measurements of the Speed of Sound and the Absorption Coefficient for Ion Exchange Resin Embedded in Concrete and Bitumen Using Ultrasonic Waves at around 0.1 MHz

摘要

Ultrasonic measurements have been carried out on concrete and bitumen containing ion exchange resin. The speed and absorption of sound was determined for different amounts of resin, different times after preparation of the samples, and for different temperatures. The absorption data indicate that it should be possible to use the technique on full-scale waste products. The data also indicate that the velocity of sound is sensitive to several parameters of interest in radioactive waste treatment and storage. The technique may also be used to gain information on the internal disposition of a waste package. (Atomindex citation 13:696523)
