Concerns over the proliferation and instances of nuclear material in the environment have increased interest in the expansion of nuclear forensics analysis and attribution programs. A new related field, molecular forensic science (MFS) has helped meet this expansion by applying common scientific analyses to nuclear forensics scenarios. In this work, MFS was applied to three scenarios related to nuclear forensics analysis. In the first, uranium dioxide was synthesized and aged at four sets of static environmental conditions and studied for changes in chemical speciation. The second highlighted the importance of bulk versus particle characterizations by analyzing a heterogeneous industrially prepared …

Following the Fukushima Daiichi nuclear power plant disaster in March, 2011, various radioactive isotopes were emitted from the plant [Ewing, 2011]. We hypothesized that emissions would bind to particulate matter, which then could be dispersed by wind currents and deposited across the planet. We analyzed an aerosol sample collected with a high volume cascade impactor in the Kittitas Valley of Washington state. NaI(Tl) gamma spectrometry revealed the presence of the isotopes 132Te and 131I, consistent with the type of nuclear accident at Fukushima Daiichi.
