I have seen the RadNet data before. Can you tell us what type of detector is being used? (I assume sodium-iodide) What is the energy resolution? And what is your minimum detectable activity?
Just saying "spikes" in cpm is not enough information to go off of. The real question is what is your cpm distribution over a long time period before the Fukushima event? Your MDA should be 3 standard deviations above the mean of that baseline data. Can you publish that number as this would be helpful in correlating our data with RadNet.
Also, has anyone done a calibration from uCi/liter air to cpm for each energy range? If so, is this published anywhere?
