MCAS Iwakuni Helicopter Radiological Remediation

Following the 2011 earthquake and the tsunami, the Fukushima Daiichi nuclear power plant sustained substantial damage, releasing radionuclides into the atmosphere. As a result, radiological fallout contaminated the Japanese and U.S. Navy MH-53 helicopters in the area.

Salas O’Brien provided critical support for this situation, including radiological characterization, oversight, disassembly, decontamination, packing and shipping of radiologically contaminated materials, and final clearance surveys and release of parts and the airframes for use by the Navy. In addition, we uploaded the corresponding survey data and the release notifications to the Joint Deficiency Reporting System (JDRS) for record archival.
