| "All naturally occurring families of radioactive elements generate helium as they decay. If such decay took place for billions of years, as alleged by evolutionists [there go the creationists assertion evolutionary scientists are also geophysicists], much helium should have found its way into the earth's atmosphere. Taking into account the slow rate of escape of helium from the atmosphere into space, and assuming no helium was in the atmosphere to begin with, it would take less than two million years to accumulate the small amount of helium in the air today." --- Vardiman, L. |

THE TRUTH:
|
"Banks and Holzer [1] have shown that the polar wind can account
for an escape of 2 to 4 x 106 ions /
cm2.sec of 4He, which is nearly identical
to the estimated production flux of (2.5 +- 1.5) x
106 atoms / cm2.sec. Calculations for
3He lead to similar results, i.e., a rate virtually
identical to the estimated production flux. Another possible
escape mechanism is direct interaction of the solar wind with
the upper atmosphere during the short periods of lower
magnetic-field intensity while the field is reversing. Sheldon
and Kern estimated that 20 geomagnetic-field reversals over the
past 3.5 million years would have assured a balance between
helium production and loss."
