Gotta decon this tank. Reading 100Rem/hr at the bottom. ~3000mRem/hr 3-4 feet away. Got any ideas? Decon material, process, etc?
The medium inside the tank is 'Powdex Resin' flowing thru a 4" drain. The tank is rubber lined. Probably some impregnation in the liner, flushing isn't working, sediment settles back to the bottom after the flush.
