Introduction In the final report of ICR’s Radioisotopes and the Age of the Earth (RATE) project, Dr.
Russell Humphreys reported that helium diffusion from zircons in borehole GT-2 at Fenton Hill, New Mexico, gave an age for the earth of 6,000 ± 2,000 years.
H, half-life of 12.43 years (Unterweger and others, 1980)) has provided an excellent tracer of young waters.
Tritium input to ground water has occurred in a series of spikes following periods of atmospheric testing of nuclear devices that began in 1952 and reached a maximum in 1963-1964. Tritium measurements alone can be used to locate the depth of the mid-1960s bomb peak, but, because of radioactive decay, many samples may need to be collected and analyzed today to locate its position.
Determination of the H in the water sample (Schlosser et al., 1988, 1989).
As these substances are virtually inert in ground water, unaffected by ground-water chemistry and unaffected by contamination from most anthropogenic sources, He dating complements existing capabilities within the U. Geological Survey for dating of young ground water, such as, uses of chlorofluorocarbons and sulfur hexafluoride, and can be applied to dating water recharged since about 1965.

In systems younger than the mid-1960s, the bomb peak will not be present due to radioactive decay.
Although initial H input to ground water and may be used to determine the position of the mid-1960s bomb peak in recharge areas.
A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.This young age agrees with a literal reading of Scripture, but is at variance with the billions of years conventionally held.Gary Loechelt has been a frequent critic of Humphreys’ procedures for calculating the young age by helium diffusion.Additionally, location of the mid-1960s bomb peak provides information on recharge rate (Schlosser and others, 1988, 1989; Solomon and Sudicky, 1991; Solomon and others, 1992, 1993; Ekwurzel and others, 1994). Locating the position of the mid-1960s bomb peak is difficult due to the required high density of vertical sampling and, therefore, is often an impractical means of obtaining ground-water age information.

Geologists do not directly measure the age of a rock.
