Maybe you should have some understanding of the units you're talking about 1.89 microSv/h is less that 2/10ths of a millirem and this was a cloud? We would have to evacuate Denver or most of Colorado based on those numbers. The rest of your BS numbers are equally as silly. Stop hanging around anti-nuclear sites and look up and understand the science for yourself. The problem is that comprehension requires knowledge and you have none.
Pay attention, that from a zero baseline starting point. You can say the spike is irrelevant but you can’t prove that it is. Were they testing or should they be testing for other fallout, like plutonium?
Here, you can downplay this finding too as some form of minor aberration along with all the other recent aberrations.
