Before the chemical decontamination treatment, the equipment was measured in two separate hot spots using a Geiger counter. The spots registered at 215 CPM and 400 CPM. For the application to be successful, the NORM radiation levels must be reduced to below 190 CPM.
Then, the patented chemistry FQE NORM-Clear was circulated for only 6 hours. It was found that this method did not cause corrosion, erosion, or undue damage to the flow meter or any of its’ integral components.
After circulation and treatment was complete, the hot spots were remeasured and were effectively reduced to 80 CPM and 100 CPM, which is the background radiation level at the site.
