•US radiological assessments are composed of aerial and
ground measurements and
indicate the amounts of radiological material that has settled on the ground.
•Each measurement
corresponds to the radiation a person receives in one hour at that location. AMS data is
presented as exposure
rate 1 meter from the ground at the time the measurements occurred.
•All measurements in this plot are below 0.03 Rem per
hour – a low but not
insignificant level.
