Fwd: [Safecast Jpn] Radiation map gives close-up fallout readings

[Pieter Franken]

Kei/Tom, do you have any insights in the accuracy of these helicopter measurements. I'm curious how the system got calibrated to work fine for a wide area.

I believe Safecast has already discussed this, but I'll mention it again (because I'm old LOL!).

The readings taken from the air are not particularly accurate because of the distance from the ground to the aircraft, neh?

So, how do the "official" readings compare with the Safecast numbers?

And how do the "official" identified "hotspots" compare to Safecasts?

First, I have to read all the agreement and think whether to accept it...
