Apollo 11 brought back some moon rocks. The rocks were dated using 4 different methods. The range between the oldest and youngest date was almost 4-billion years. Apollo 16 brought back some moon rocks that were dated at 18-billion years. To fix the problem they subjected the rocks to acid to melt out the lead and then re-dated and got 4.5 billion years. (Science magazine Jan 30, 1973) Sunset Crater in n. Arizona is known to be a recent volcano. Indian artefacts and relics are found within the rocks formed by the eruption. The volcano last erupted some 900 years ago. Two lava flows have been dated giving ages of 210,000 and 230,000. Hualalai volcano in Hawaii Known to have erupted in 1800-1801 were dated with a variety of methods. 12 dates were taken which ranged from 140 million years to 2.96 billion years. The average date was 1.41 billion. There have been many explanations to explain these results away (as the lava rose, the older material from inside the earth rose with it, but they are unable to explain why such a variance in ages). If this is the explanation, then why could this not also be the case for other dates? This does not disprove radioisotope dating, but it does demonstrate the tremendous inconsistency in the interpretation of the method. The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in 1986 gives a whole rock K-Ar ‘age’ of 0.35 0.05 million years. Steven A. Austin, “Excess Argon within Mineral Concentrates from the New Dacite lava Dome at Mount St. Helens Volcano, 1996

2. Carbon-14 dating Radioisotope dating The Biblical age of the earth
3. The Atom Fundamental unit of matter Made up of components called subatomic particles Proton (positive charge) Neutron (no electrical charge) Electron (negative charge) Nucleus Electron
4. Carbon has unique properties that are essential for life on earth. Familiar to us as: 1. the black substance in charred wood, 2. as diamonds, 3. and the graphite in ‘lead’ pencils, also
5. carbon comes in several forms, or isotopes. One rare form has atoms that are 14 times as heavy as hydrogen atoms:
6. Carbon-14 is also referred to as: C-14 Carbon-1414 C Radiocarbon Types of carbon (isotopes) Atomic mass 9 14 16 6 C 6 C 6 C Atomic number
7. Atomic Mass The atomic mass (ma) is the mass of an atom at rest, most often expressed in unified atomic mass units. The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless).
8. Atomic Number The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element.
9. In an atom of neutral charge, the number of electrons also equals the atomic number. The atomic number is closely related to the mass number, which is the number of protons and neutrons in the nucleus of an atom. The mass number defines the isotope of the element and often comes after the name of the element, e.g. carbon-14 (used in carbon dating).
10. What is Radioactive Decay? The nucleus of an atom changes into a new element The proton number (atomic number) must change A neutron changes into a proton 14 14 6 C 7 N
11. Carbon-14 is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere. These displaced neutrons, now moving fast, hit ordinary nitrogen (14N) at lower altitudes, converting it into 14C. Unlike common carbon (12C), 14C is unstable and slowly decays, changing it back to nitrogen and releasing energy. This instability makes it radioactive.
12. Ordinary carbon (12C) is found in the carbon dioxide (CO2) in the air, which is taken up by plants, which in turn are eaten by animals. So a bone, or a leaf or a tree, or even a piece of wooden furniture, contains carbon. When the 14C has been formed, like ordinary carbon (12C), it combines with oxygen to give carbon dioxide (14CO2), and so it also gets cycled through the cells of plants and animals.
13. How C-14 is Produced Cosmic Rays (radiation) Forms C-14 C-14 combines with oxygen to form carbonCollision withatmosphere (N14) dioxide (CO2)
14. We can take a sample of air, count how many 12C atoms there are for every 14C atom, and calculate the 14C/12C ratio. Because 14C is so well mixed up with 12C, we expect to find that this ratio is the same if we sample a leaf from a tree, or a part of your body.
15. How the Carbon Dating Clock Works Once a plant or animal dies the clock starts The plant or animal no longer takes in C-14 The C-14 present in the plant or animal begins to decay No more C- C-14 continues 14 intake to decay
16. In living things, although 14C atoms are constantly changing back to 14N, they are still exchanging carbon with their surroundings, so the mixture remains about the same as in the atmosphere. However, as soon as a plant or animal dies, the 14C atoms which decay are no longer replaced, so the amount of 14C in that once-living thing decreases as time goes on. In other words, the 14C/12C ratio gets smaller.
17. So, we have a ‘clock’ which starts ticking the moment something dies. Obviously, this works only for things which were once living. It cannot be used to date volcanic rocks, for example.
18. The rate of decay of 14C is such that half of an amount will convert back to 14N in 5,730 years (plus or minus 40 years). This is the ‘half-life.’ So, in two half-lives, or 11,460 years, only one-quarter will be left.
19. Carbon-14 Life CycleCosmic radiation 14 14 14 7 N 6 C 7 N 5,730 year half-life
20. Thus, if the amount of 14C relative to 12C in a sample is one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years. Anything over about 50,000 years old, should theoretically have no detectable 14C left. That is why radiocarbon dating cannot give millions of years. In fact, if a sample contains 14C, it is good evidence that it is not millions of years old.
21. However, things are not quite so simple. First, plants discriminate against carbon dioxide containing 14C. That is, they take up less than would be expected and so they test older than they really are. Furthermore, different types of plants discriminate differently. This also has to be corrected for.
22. Second, the ratio of 14C/12C in the atmosphere has not been constant—for example, it was higher before the industrial era when the massive burning of fossil fuels released a lot of carbon dioxide that was depleted in 14C. This would make things which died at that time appear older in terms of carbon dating. Then there was a rise in 14CO2 with the advent of atmospheric testing of atomic bombs in the 1950s. This would make things carbon-dated from that time appear younger than their true age.
23. Measurement of 14C in historically dated objects (e.g., seeds in the graves of historically dated tombs) enables the level of 14C in the atmosphere at that time to be estimated, and so partial calibration of the ‘clock’ is possible. Accordingly, carbon dating carefully applied to items from historical times can be useful.
24. However, even with such historical calibration, archaeologists do not regard 14C dates as absolute because of frequent anomalies. They rely more on dating methods that link into historical records. Outside the range of recorded history, calibration of the 14C clock is not possible.
25. Carbon-14 Dating Used only on organic material Cannot be used to date rocks Maximum age limit about 60,000 years
26. Quantity of C-14 in a FossilThe C-14 dating method relies on measuringthe amount of C-14 in the fossil If there is a lot of C-14 remaining in the fossil, we assume it has not been dead very long If there is very little C-14 remaining in the fossil we assume most of it has decayed and the animal lived a long time ago (i.e. 30,000 or more years)
27. What Do We Need to Know? We need to know two things1. How fast C-14 decays (measured in half-lives - this is known: 5,730 years)2. The starting amount of C-14 in the fossil We know number 1 How can we know how much C-14 was in an organism 5,000 years ago?
28. Calculating the Starting Amount of C-14 The dating method relies on measuring the ratio of carbon-12 to carbon-14 in the sample The ratio today in the atmosphere is 1- trillion to 1

30. The Underlying Assumption Has the ratio of C-12 to C-14 in the atmosphere always been the same?If YES, then the C-14 dating is valid for up to60,000 yearsIf NO, then we have no valid way of knowing thestarting amount of C-14 and dates will be invalid 30,000 years to reach equilibrium

Libby, Radiocarbon Dating, 1955)“He found a considerable discrepancy in hismeasurements indicating that, apparently,radiocarbon was being created in theatmosphere somewhere around 25 percent fasterthan it was becoming extinct. Since this resultwas inexplicable by any conventional scientificmeans, Libby put the discrepancy down toexperimental error.”
32. Experiments on Equilibrium“During the 1960s, Libby’s experimentswere repeated by chemists… The newexperiments, though, revealed that thediscrepancy observed by Libby was notmerely an experimental error – it did exist.”Richard, Milton, Shattering the Myths of Darwinism,1997, p. 32.
33. Experiments on EquilibriumRichard Lingenfelter, “Production of C-14 by cosmicray neutrons”, Review of Geophysics, 1963, p.51. “There is strong indication, despite the large errors, that the present natural production rate exceeds the natural decay rate by as much as 25 percent.”
34. New Techniques Show Young DatesWalter Brown (Ph.D. Mechanical Engineering andProfessor of Physics), In the Beginning, 2001, p. 245.“The new atomic accelerator technique hasconsistently detected at least small amounts ofcarbon-14 in every specimen – even materialsthat evolutionists claim are millions of years old,such as coal…In one study of eleven sets of ancient humanbones, all were dated at about 5,000 radiocarbonyears or less.”
35. The amount of cosmic rays penetrating the earth’s atmosphere affects the amount of 14C produced and therefore dating the system. The amount of cosmic rays reaching the earth varies with the sun’s activity, and with the earths passage through magnetic clouds as the solar system travels around the Milky Way galaxy.
36. A stronger magnetic field deflects more cosmic rays away from the earth. Overall, the energy of the earth’s magnetic field has been decreasing, so more 14C is being produced now, than in the past. This will make old things look older than they really are.
37. Also, the Genesis flood would have greatly upset the carbon balance. The flood buried a huge amount of carbon, which became coal, oil, etc., lowering the total 12C in the biosphere (including the atmosphere—plants regrowing after the flood absorb CO2, which is not replaced by the decay of the buried vegetation). Total 14C is also proportionately lowered at this time, but whereas no terrestrial process generates any more 12C, 14C is continually being produced, and at a rate which does not depend on carbon levels (it comes from nitrogen).
38. Therefore, the 14C/12C ratio in plants/animals/the atmosphere before the flood had to be lower than what it is now. Unless this effect (which is additional to the magnetic field issue just discussed) were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages.
39. The key assumption has been shown to be false(equilibrium)Carbon-14 dating is a reliable dating method for lessthan 3,000 years and not the claimed 60,000 found inmany textbooks Carbon-14 dating is based on an assumption
40. Radioisotope Dating MethodsWhat are they and how do they operate? What is the basic perception? How accurate are they? Are there any hidden assumptions?
41. EducationBiology: Visualizing Life, Holt, Rinehart,Winston, 1998, p.177. “Using radioactive dating, scientists have determined that the Earth is about 4.5 billion years old, ancient enough for all species to have been formed through evolution.”
42. EducationNational Association of Biology Teachers(NABT), 1995 Position Statements. “Radiometric and other dating techniques, when used properly, are highly accurate means of establishing dates in the history of the planet and in the history of life.”
43. There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks. These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.
44. Understanding AssumptionsFor example, potassium-40 decays to argon-40;uranium-238 decays to lead-206 via other elementslike radium; uranium-235 decays to lead-207 Uranium Decay Lead Potassium Decay Argon
45. The isotope concentrations can be measured very accurately, but isotope concentrations are not dates. To derive ages from such measurements, unprovable assumptions have to be made such as:
46. 1. The starting conditions are known (for example, that there was no daughter isotope present at the start, or that we know how much was there).2. Decay rates have always been constant.3. Systems were closed or isolated so that no parent or daughter isotopes were lost or added.
47. These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.
