Hi, Joseph,

At the time, Radsafers made me aware that it was under-reporting, I 
should have mentioned that, sorry.

I do not know if there was any GLE activity at the time of the flight. 
The date and time are there if there is a database of such things.

It was surprising how much more the meter measured at cruising 
altitude--makes me happy we have the atmosphere that we do! While I used 
to fly one to two trips a month, I no longer do that, but this is not 
one of the reasons why--I did not find this alarming, just interesting.

I rejoined RadSafe to feel reassured that I was "misinterpreting" the 
news as waaay over the top. Thanks--people who understand this stuff 
(unlike me, who doesn't understand it in depth) are saying it's bunk, too!
