A summary of the physical
phenomena involved in radiocarbon dating is given. Laboratory procedure
determines the amount of radioactive carbon a sample contains now. Calculation
of an age requires an assumption concerning the relative amount
of radioactive carbon in the environment at the time the organism from
which sample was derived was living. The year A.D. 1850 is chosen as
a standard since up to then man had not contaminated the air by either
adding carbon dioxide from industrial fuel or neutrons from atomic explosions.
Thus a decrease to one half of the amount found in A.D. 1850 samples
indicates a radiocarbon age of 5730 years. Correlation with tree-ring
dating shows a fair degree of accuracy to about 59. B.C. Attempts to
correlate Bristlecone Pine growth-rings with radiocarbon age show a
discrepancy of 500 to 1000 years, the pine ages being that much older
than Carbon-14 ages. Reliable conversion between historical age and
radiocarbon age goes back only 3-4000 years. Though only approximations,
farming increased rapidly in 1200 "years" from 7,200 to 5,000
B.P. Evidently prior to the Flood the relative amount of Carbon-14 in
the air was only about 1/1000
of its present value. Several theories for increase in Carbon-14 are
Radiological Dating And Some
Pertinent Applications Of Historical Interest
Do Radiological "Clocks"
Melvin A. Cook, Ph.D.
Radiocarbon dating is based
on the incorrect assumption that C-14 is in equilibrium, the rate of
formation equaling the rate of decay. But recent data show rate of formation
is 18.4 and rate of decay 13.3 so that a non-equilibrium condition exists.
This situation telescopes all radiocarbon ages to about 10,000 years
or less. Consideration of uranium-thorium-lead age determinations show
at least six basic difficulties involved in determining true age. Most
serious is evidence for artificial aging by the so-called "neutron-gamma"
reactions. A number of crucial examples are given. Thus the uranium
ore at Shinkolobwe, Katanga contains no thorium or common lead, but
.08% Pb-208! If it came from "neutron-gamma" reactions, the
likely explanation of this ore, it is a modern ore, far younger than
the assigned 640 million year old age of conventional dating!
Potassium-argon dating does
not take into account the relatively great amount of argon-40, branching
ratio data, and uncertain half-life of some isotopes. Pure guess work
is required to establish the actual concentrations of the isotopes
involved in the rubidium-strontium "time clock" at the beginning
of a particular mineral.
An extensive discussion
of radiocarbon dating in relation to a global sea level cycle is given.
Also dates of various civilizations based on a equilibrium radiocarbon
model are shown to be seriously older than reality.
Radiocarbon Confirms Biblical
Creation (And So Does Potassium-Argon)
Robert L. Whitelaw
The C-14 method of dating
not only confirms Biblical history, but creation also. Similarly the
potassium-argon method cannot be used to establish ages older than about
Libby found a discrepancy
indicating a non-equilibrium in the build-up of terrestrial radiocarbon.
But, since he was convinced that the earth was millions of years old,
he decided the difference between the C-14 production rate of 19 atoms/gm-min.
And the specific activity of 16 dis/gm-min was due to experimental error.
Actually this difference is greater and is to be expected on the basis
of a relatively recent Creation. Allowing for this difference and computing
backward leads directly to the Biblical creation date.
The vulnerability of the
potassium-argon method of dating lies in the difficulty of knowing how
much of the argon came from potassium, a determination absolutely vital
to all age determinations. Since 99.6 of argon is Ar-40 and .337% is
Ar-36, the ratio of 99.6 to .337 or 295.6 would give the amount of argon
coming from potassium in the equation: Radioargon 40 = total argon 40
- 295.6 times argon 36. But this assumes the ratio of Ar-36 to
Ar-40 since the beginning. If cosmic radiation began with Creation,
the present Ar-36 concentration of .337% would have built up
from zero since then, so that the constant of 295.6 must increase rapidly
as one goes backward in time.
On The Invariance Of The
Decay Constant Over Geological Time
Robert V. Gentry
Radioactive inclusions such
as zircon, which show a considerable volume increase due to isotropization
from radioactive decay, often fracture the surrounding mineral in a
random pattern. On uniformitarian concepts the surrounding mineral should
expand slowly over geologic time. Expansion cracks should occur first
along cohesion minimums and grain boundaries, but instead individual
cracks surrounding the radioactive inclusion are randomly distributed
and occur suddenly, in an explosive fracture. Anomalous decay rates
would explain this world wide phenomena. Mathematical equations showing
the relationships involved in pleochroic halos are given.
A Paleoecological Misinterpretation
Harold G. Coffin
The small marine tubeworm,
Spirorbis, is abundant in the fossil record. No member of this
genus is found in a fresh water habitat. Since Spirorbis tubes
are found as a constituent of Carboniferous coal, they are strong evidence
for the allochthonous, or transported, origin of much of the coal. This
is contrary to the presently popular view that coal originated in swamps
and marshes due to the accumulation of plant materials over long periods
