In two geographically-separated locations, one as far away as 15 km, radioactive microparticles containing percent-concentrations of thorium were detected in ashes and dusts that were likely related to deposition from the Woolsey fire. These offsite radioactive microparticles were colocated with alpha and beta activity maxima. Data did not support a finding of widespread deposition of radioactive particles. However, two radioactive deposition hotspots and significant offsite contamination were detected near the site perimeter.

"These fires aren't even in forests," said Max Moritz, a wildfire specialist at the University of California, Santa Barbara.

The Woolsey Fire broke out at the site on Nov. 8, 2018, sparked during high winds by electrical equipment owned there by Southern California Edison, an investigation by the Ventura County Fire Department concluded. The blaze went on to burn about 97,000 acres, including 80% of the field lab site, ... The study examined 360 samples of household dust, surface soils and ash from 150 homes and other locations such as parks and trails collected after the fire. It concluded that while most of the collected samples were at normal levels, "some ashes and dusts collected from the Woolsey Fire zone in the fire's immediate aftermath contained high activities of radioactive isotopes associated with the Santa Susana Field Laboratory."
