Back to the "cosmic ray visualization" thread... --the results are 
downright outstanding. Great work, Wolfgang!

Hi Michael,

I knew you would have to change sides on this one sooner of later.  
That's a relief!

I tried to send you those darks over the weekend but the email was 
kicked back.  Not sure if it was my server or yours that thought the 
package was too large.  But now that you are looking at this, I am still 
interested in the flux that you are finding - you know, hits / sq mm / 
min sort of thing.  I am getting emails off the list that indicate my 
counts are lower than what they see.  But the counting is pretty hard to 
do manually, especially if you don't use  Justins' mostdev.exe.  Maybe 
you can automate this?

On the source of radiation: a LBNL study analyzed (as only they can) the 
types of radiation and found that Potassium90 was the most common local 
source of the gamma radiation's Compton scattering electrons.  It is 
often a contaminant in glass and sometimes in aluminum and concrete.
