[ RadSafe ] Helium suppies endangered, threatening science and technology

[Doug Aitken]

Otto, there is a big difference between total supply (even if constantly
replenished) and recoverable supply (e.g. economically viable).

Just ask the oil men out there.......

So it would seem to be prudent to take some care to minimize waste (goes for
most things, too!)

Regards and happy new year!
Doug

I think the article vastly underestimates the helium reserves of the 
earth. As noted in the article, every alpha particle emitted by the 
naturally-occurring alpha emitting radionuclides in the uranium and 
thorium decay series found in all the rock and soil of the earth 
constantly generates helium. If there was not an immense quantity 
continually being generated there would be no helium on the earth 
even without human use. It seems quite unreasonable to assume that 
the puny human use of helium could significantly deplete the earths 
constantly replenished supply.
