THanks, Joe - I concur.  An interesting bit of history, though!

Harlan, I don’t see a direct comparison because of the threshold LET in the plastic compared to the energy range of CRaTER.
The Science paper states they are sensitive to Ne ionization above 7 MeV/n incident, but that means lower incident energy than CRaTER can detect for heavies.
Our track experts might have another view.
 
Here's the relevant figure from the lexan reference in the Science paper:

All, 
 
   Here is a link to the paper we discussed at yesterday’s CRaTER telecon.  Please let me know if you have any thoughts on if/how we might/should compare these Apollo era radiation measurements with ours.
 
Thanks,  Harlan

Harlan and Nathan,
 
How do the results from this interesting experiment compare to CRaTERs data?
