animals get their carbon-14 from the atmosphere. ( Dalrymple, 1984,.88) Believe it or not, a number of creationist attacks against radiometric decay rates are aimed at a kind of "decay" called internal conversion (IC which has absolutely nothing to do with the radiometric dating methods ( Dalrymple, 1984,.88). Therefore, the half-life of a radioactive element is independent of the amount of sample. Or K-capture in which an orbital electron is captured by the nucleus and a proton is converted into a neutron. This nullifies the carbon-14 method as well as demonstrating that the earth is less than 10,000 years old. Advantages include the ability to date an object without destroying it, having many different techniques to choose from, and the ability to procure a relatively accurate age of objects that are hundreds of thousands, millions, or even billions of years old. The water coming out of the hose is analogous to the continuous production of carbon-14 atoms in the upper atmosphere. It's not clear to me what. This statement merely reveals Slusher's ignorance of nuclear physics.
Not every mollusk shell presents such problems, and the dating of other material might yield a cross-check. For example, a small amount of 133I is injected into the patient and kidneys are scanned with a radiation counter in the case of blocked kidney. As it turns out, we have a check on the carbon-14 production which goes back even further than 8000 years: Evidence of past history of C-14 concentration in the atmosphere is now available through the past 22,000 years, using ages of lake sediments in which. The earth's magnetic field seems to have the greatest effect on C-14 production, and there is no reason to believe that its strength was greatly different even 40,000 years ago. Jennifer Hillam of the University of Sheffield and Mike Baillie of Queen's University of Belfast and their colleagues were able to date the walkway by a second method,.e., tree-ring dating. It makes up less than one part per million in the atmosphere, and claiming to be able to measure accurately to 7 decimal places is not reasonable. Lab contamination and technique can be checked by running blanks. Because this new element (decay product) remains on or within the object, scientists can easily determine how old the object. Insect burrows, cracks, and partial decay may allow contamination later on to affect those portions of the sample unequally.
