Initial leach test results on enamels prepared with Ce/sup 144/Cl/sub 3/ indicated extremely low rates of water leaching at room temperature. However, the rate of Ce/sup 144/ removal from the enamel in boiling water was appreciable. Experiments with solvents, acid, and alkali as the leaching media are in progress. A non-active cerium enamel was prepared using a furnace capable of higher operating temperatures than those previously obtained. The resulting glass was higher melting than recent preparations and was completely free from undissolved materials. This batch of enamel was used to prepare slides for thermal and mechanical shock tests. The radiation dose rats emitted from cerium-containing beta source slides is being evaluated by means of photographic film dosimetry. Results to date were obtained in terms of total dose rate which includes natural beta and gamma emission plus bremsstrahlung due to interaction of beta particles with the enamel and stainless steel backing. A number of modifications were made in the hot cell facility in order to maintain ssfety and ease of operation. The cell is now ready for continued preparation of active enamels. (auth)
