1.0 Site Identification

2.0 Site Status Summary

This site was added in anticipation of NARM Final Rule. The current site has Radium-226 contamination of storage areas with scattered spots throughout the main building due to past radium paint stripping operations of aircraft instruments/gauges. An assessment of soil and groundwater thus far indicate no impact, however, more extensive sampling may need to take place once the license termination process begins. This licensee is currently evaluating disposal options in order to meet a license condition prohibiting long term storage of radium painted aircraft instruments/gauges. The current storage area has additional postings as an airborne radioactivity level due to high radon level (160 pCi/L) and a radiation area due to a 5-gallon paint can reading > 10 mR/h at 30 cm. This site has been evaluated by the Kansas Department of Health Bureau of Environmental Remediation for potential soil and groundwater contamination related to past Radium-226 soil contamination due to dumping radium contaminated solvents from aircraft instrument stripping operations and subsequent cleanup. A Unified Focused Assessment Report has been prepared by KDHE BER and a summary is available online at http://kensas.kdhe.state.ks.us/pls/certop/Iop?id=C208772046
