Hi Joe - I am taking the afternoon off so here are the quiz answers early:
#1 - Bismuth
#1A - 1.9 x 1919 years - yep, pretty much stable element based on human
time lines
#2 - PuO2
As for the 250 million hours, I don't have a clue on how they calculated
that value other than the Voyager space crafts have been "way out there"
for quite a few years.
Bev wins the Diet Mt. Dew from Doug with honorable mention to Mike.
That is around 28,500 years so either there are thousands of these devices
out there in space or the space program is a lot older than I thought...?
;-)? On the other hand I may be missing something in the accounting that I
am not familiar with.
Cheers,
Joe
