to the public without referencing limits set by regulations, as it allows one to make direct comparisons to natural background radiation. The last sample listed in [**Table \[tab:fukushimafood\]**]{} are weeds collected after the rainfall described by Norman in 2011 [@Norman2011] that had absorbed $^{134, 137}$Cs from Fukushima fallout. These weeds were cooked and washed very thoroughly in an attempt to determine whether the activity was inside the plants or merely surface-contaminated, and recounting proved that the activity was indeed absorbed inside the plant matter. The weeds were recounted in October 2013 along with the food samples in [**Table \[tab:fukushimafood\]**]{} as a comparison. Then the weeds were recounted again in November of 2013 along with the Philippines tuna sample as seen in [**Figure \[fig:weedstuna\]**]{}, this time on a lower background system; the same 115% HPGe system at the LBNL LBF used in the air monitoring efforts. The results of the low background counting of these samples are seen in [**Table \[tab:merweedstuna\]**]{}. These weeds were used as a proxy for Fukushima fallout– the ratio of $^{134}$Cs/$^{137}$Cs was compared to the $^{137}$Cs we detected in our food samples, which confirmed that if the $^{137}$Cs was indeed from Fukushima, we should have easily seen
