Carbon dating industrial revolution
Places that it should not exist at all. The earth's magnetic field was stronger in the past, causing inflated ages.
In the atmosphere the amount of Carbon decaying over time increases with the greater concentration of Carbon in the atmosphere. This is not the end, but merely the start of a long list of things that demonstrate the total uselessness of the Carbon method. Recent experiments suggest that radioactive decay rates assumed to be constant can change due to causes that are not yet fully understood.
Carbon years differ from calendar years because they are dependent on varying amounts of Carbon in the atmosphere. Radiocarbon dates are based on the assumption that radioactive decay rates have been constant in the past. However, if we could measure the amount of Carbon in the atmosphere when they lived, we would be living during the time and there would be no reason for dating. Experiments done with the radioactive isotopes of Uranium and Iron have shown that rates not only do vary, but can, in fact, be altered by changing the environment surrounding the samples.
The curves are, however, constantly being revised and different calibration curves are used which yields widely different results depending upon the choices made by the researcher. Thus, the older a sample is the wider the uncertainty of the date. In theory the cycle will continue indefinitely.
Radiocarbon Date calculation
Atoms of given elements have different Isotopes. Anything beyond that is questionable. The gas is then subjected to more purifying procedures. Poole In the laboratory, samples must be processed and cleaned so that there is no material on them that might throw off the age reading.
