Re[2]: Saturn Probe Pu Power?

["GLEN VICKERS"<brzgv@ccmail.ceco.com>]

     I respectfully and somewhat jokingly say, "Who cares about the 
     insignificant amount of Pu on a satellite".
     
     Does anyone have any insights on the post I sent the other day on the 
     ALARA "TEDE" evaluation thread?  My response was in the unique area of 
     power plant steam generator maintenance and I was hoping to share 
     insights with others in that area.  I do; however, realize that there 
     aren't that many person's with thoughts/experience in that particular 
     area on this list server.  How about other jobs in general with high 
     external rates and high DAC value contributors?  How about the other 
     extreme?  
     
     This is a good area to value the opinions of those with much 
     experience.
     
     Sincerely,
     Glen Vickers

In average soils, Thorium-232 is present at levels of 2 - 3 ppm, which 
is a couple of micrograms for every gram of soil on the earth!  This is 
much more than a couple of tons. OK, the specic activity is much lower 
for Th-232 than for Pu-238 but the availability of Th-232 is much 
higher.
