| 2015/7/10 | Begin long purge at 1000, finish purge at 1030. Good desiccant about 2 inches remaining. Flow rate of large purge cabinet: 1.5 scf/h; flow rate of small purge cabinet (top): 3 scf/h; (bottom): 2.5 scf/h. Start 1 week run in large purge cabinet at 1040. Desiccant tube in cabinet, hose going through the outlet (outlet valve removed), some teflon tape to help seal between hose and outlet hole.

the plan: finish this 1-week run in the large cabinet, then immediately follow with a 2-day test - at the beginning of this test, open the door for a minute, then close it. This should show how long it takes for the N2 purge to remove the radon from the cabinet.
