tested.against both criteria and that if it meets either (or both), it will be disposed as radwaste.

2. Your answer to our question 25 describes periodic radiation measurements that will be taken during the decommissioning process. You state that you will monitor airborne radioactivity continuously with samples analyzed weekly. Please provide additional details about your' plans for monitoring airborne radioactivity.

3. Your. answer to our question 31 provides details on the survey instruments to'be used to make 5 uR/hr above background measurements needed to justify license termination by'the NRC.
