[ RadSafe ] Gamma measurements in planes

[Tosh Ushino]

Ladies and Gents,

I haven't been following RADSAFE for quite a while, and please excuse me if someone else already responded with this.

There are couple of web pages that show solar weather. The second one below has a plot of 3-days of 5-minute solar x-ray flux values measured on the SEC primary and secondary GOES satellites.

http://www.spaceweather.com/
http://www.sec.noaa.gov/today.html

Perhaps solar weather will help explain the anomaly observed in the airplane.

I wish you all Happy Holidays.

Tosh Ushino

On a recent trip to FL from Boston, my RadEyeG measured 0.01 mr/hr on
the ground and 0.40 mr/hr at 35Kft during the day.  On the return flight
the next night it measured 0.01 on the ground and 0.30 mr/hr.  These are
completely unscientific since I probably changed locations relative to
DU ballast if any.  Also, I don't know what energies were involved and
therefore can't correlate the response of the RadEyeG.  Still it was
interesting.

There has been some writing about dose rate measurements in planes. I
seem to recall that DU can be used as ballast in planes. Even though not
exceptionally active, I suppose that could affect measurements somewhat
inside a plane!
