Radium dating problems updating catalyst drivers
Furthermore, if a sample has been contaminated, scientists will know about it.Ironically, given how supposedly useless carbon dating is claimed to be, Creation Ministries International rests part of their "101 Evidences" on carbon dating being a useful method for within several thousand years.The level of atmospheric Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.A favorite tactic of Young-Earthers involves citing studies which show trace amounts of Indeed, this results from a unique decay mode known as "cluster decay" where a given isotope emits a particle heavier than an alpha particle (radium-226 is an example.) This fact is extremely inconvenient to them, and creationist literature, accordingly, usually does not mention it.Beyond that timespan, the amount of the original C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.
Radium, for example, has a half-life of about 1,600 years.
Radium is chemically related to barium and calcium and therefore accumulates, e.g., in Brazil nuts so that it is contained in Brazil nut ash.
The content, which fluctuates depending on the area of cultivation, is of the order of magnitude of 10 picograms per gram of ash. In the course of time, the isotopes of the radioactive series accumulate until an equilibrium is reached.
If you know how pure your block of radium originally was, it's relatively simple to calculate how old it is by measuring how much radium is left.
This is a very useful tool if you have solid blocks of radium that need dating, but if you don't know how much radium was there in the first place, the job is a lot harder.
