【 摘 要 】

The {sup 232}U/{sup 228}Th source has been tested for operation with the tritiated water monitor. This source has an effective half-life of 73 years and is an attractive replacement for the reactor activated {sup 24}Na sources, which have half-life of only 15 hours. The tests described in this report appraise the adequacy of this source by comparing its performance to that of {sup 24}Na used in earlier studies. The new source has already been used successfully to assist recovery operations, and it is now apparent that the monitor is ready to be turned over to SRP for routine use.
