Problems with radiocarbon dating during the last 30 years, a new method of determining c14/c12 ratios has been developed it uses accelerator mass spectrometry to determine the amounts of c14 and c12 in a small sample which is vaporised in the test. The radiometric dating game how radiometric dating works in general why methods in general are inaccurate why k-ar dating is inaccurate the branching ratio problem. The problem with dating methods for fossils textbooks speak of the radiometric dating techniques, and the datesfact that there are many scientific problems with radiometric dating, there is athe age of the fossil can be estimated within the range of the layersfor problem with dating methods for fossils the misery and suffering enclosed . In other news, i hope this shows you how you can solve any radioactive dating problem from a very tiny amount of info it's all related via some simple equations, so get familiar with them.
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, this can reduce the problem of contamination. New ways of dating rocks are supposed to be able to give ages in the billions of years these are the radiometric dating methods each of these methods is based upon the decay rate of certain elements in one method, for instance, the element uranium-238 will break down into the element lead over a . Answers to creationist attacks on carbon-14 dating reliable of all the radiometric dating methods does c-14 dating show that creates problems for the .
Radiometric dating - a brief explanation radiometric dating is the primary dating scheme employed by scientists to determine the age of the earth radiometric dating techniques take advantage of the natural decay of radioisotopes. Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials. How accurate is uranium-lead dating radiometric dating method is the uranium-lead methodthis involves uranium isotopes with an atomic mass of 238this is themind i say when i rendered it i am speaking of the pastwhen some practical joker fed a lace card through the readerj shall answer the same if you ask me fifty times. Classical oe dating (radiometric dating) is based upon the spontaneous breakdown or decay of atomic nuclei, where a radioactive parent atom decays to a stable daughter atom the exponential decay rate equation is n(t) = n(0)exp [- k t ] where k is the (assumed) positive decay constant .
Con's problem is that all the reasonable scientific comparisons verify that radiometric dating has the accuracy claimed all con has done is cite a few limitations on some of the specific methods it's true that argon dating cannot be used on samples exposed to air. Various problems with the three main types of radiometric dating lastly, an examination and discussion will be presented of how these methods can give unreliable dates. Processes or time to date rocks or other objects, scientists typically use radiometric datingin short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample. Thus, there apparently are some problems in that kind of radiometric dating general unreliability of radiometric dating the main point at issue is fractionation and its relationship to u/pb and th/pb dating.
This problem, known as the reservoir effect, is not of very great practical importance for radiocarbon dating since most of the artifacts which are useful for radiocarbon dating purposes and are of interest to archaeology derive from terrestrial organisms which ultimately obtain their carbon atoms from air, not the water. The problem is, if radiometric dating is accepted as an accurate way to date artifacts, when in fact it is not, then it is misleading people to believe artifacts are older than they really are. Still another evidence for problems with radiometric dating was given in a recent talk i attended by a man who had been an evolutionist and taken a course in radiometric dating the teacher gave 14 assumptions of radiometric dating and said something like if creationists got a hold of these, they could cut radiometric dating to pieces. The way it really is: little-known facts about radiometric dating this argument was used against creationist work that exposed problems with radiometric dating .
This same problem exists for all other relative radiometric dating techniques in addition, there are other problems with ar/ar dating such as the uncertainty of the decay constants for 40 k and 39 ar recoil. This illustrates the whole problem with the radioactive dating of geological events this is no different from the ‘criticism’ you apply to radiometric dating . Claim: radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered response: this is not at all true, though it is implied by some young-earth literature radiometric dating is based on the half-lives of the radioactive isotopes these half-lives have been measured over the last 40-90 years.
