Not enough helium in the atmosphere for an old earth (Talk.Origins)

Claim CE001:


 * The radioactive decay of several elements produces helium, which migrates to the atmosphere. There is too little helium in the atmosphere to account for the amount that would have been produced in 4.5 billion years. Escape of helium into space is not sufficient to account for the lack.

CreationWiki response:

This claim is out of date. However it can be shown that so much helium is still in the rock, that it is most consistent with young Earth.
