4/2 - 4/3 air sample results clarification

The preliminary results for I-131 for 4/2 - 4/3 show 1.21E-06. For 4/1 - 4/2 they were 1.35E-07. Is the E-06 supposed to be E-07? Otherwise it seems that the I-131 levels jumped 10x in 1 day which is contrary to your analysis of the data moving towards minimum detectability.

A 1.21E-07 number would gel much better with the preliminary results graph as well.

Or, I could just be reading it wrong.
