[ RadSafe ] FW: Reporter's question about lower limits of detection (BUSBY)

[Cowie, Michael I]

Trying to remain civil Chris, if I accept all your "assumptions" would it not be the activity concentration that would be higher and not the activity?

Mike

Dear Radmax,
Is that how you see yourself? Amazing!
Most of physics is done with estimates and assumptions, but maybe you have not ever done any real physics. You then have a calculation result with levels of uncertainty which you allow for. Otherwise most of physics cannot be done. What we do know is the activity in Cs137 and Cs134 of the filters. The cars were driven for 150km before the filters were removed. The engine cc was 600cc (these are small engines that the Jap cars use). The assumption is that the mean rpm was 2500. This is a very conservative assumption as these were commuter cars. So the real value is likely to be higher. This would make the activity higher. Perhaps you know that a 4 stroke engine transfers its cc worth of air every 2 revolutions. As to the 50% trapping assumption,this ia also likely to be conservative. So if there is any error the real value will be higher.
You, and Mr Franz, and a few others are so appallingly rude it is very difficult to deal with you as if you were scientists and not ignorant rednecks in some cheap bar. I thought the radsafe list was a discussion arena not some internet blog where idiots insult each other. Try to remain civil.
Best regards
Chris Busby

And just how did you calculate that volume... RPM's???  Were you driving with the owners of these cars?  What gear were they in?  What speed were they driving?  Correct tuning or improper air-fuel mixture?  Uphill, Downhill, standing still or moving slowly in traffic/debris fields, A/C on or off.. ?  Distance's from Fuku, time after event, direction to plume...?  How many thousands of cubic meters of air had entered these filters PRIOR to Fuku ???

50% eff but not 'sure', Really?  You always seem to 'ASSUME' alot.

Your numbers, just as the rest of your drivel, is again more ABSOLUTLEY CHERRY PICKED B.S.

Any REAL scientist would not publish anything with your levels of uncertainty.

Please just go away.  Don't come back until you have something actually 'quantifiable'.

Radmax
