What radioactive decay is used in carbon dating
Radiometric dating is a method which scientists use to determine the age of various specimens, mainly inorganic matter (rocks, etc.), though there is one radiometric dating technique, radiocarbon dating, which is used to date organic specimens. Basically, scientists take advantage of a natural process by which unstable radioactive “parent” isotopes decay into stable “daughter” isotopes spontaneously over time.Uranium-238 (U238), for example, is an unstable radioactive isotope which decays into Lead-206 (Pb206) naturally over time (it goes through 13 unstable intermediate stages before it finally stabilizes into Pb206).The three key underlying assumptions are 1) the rate of decay of parent into daughter has remained constant throughout the unobservable past; 2) the specimen which we are examining hasn’t been contaminated in any way (that is, no parent or daughter has been added or taken away at any point during the unobservable past), and 3) we can determine how much parent and daughter were present at the beginning of the decay process – not all of the Pb206 present today necessarily came from decaying U238; Pb206 may have been part of the original constitution of the specimen.If any of these assumptions are wrong, the method cannot accurately determine the age of a specimen.
The fact that bananas are radioactive has actually given rise to the radiation unit: “banana equivalent dose” (BED); this is the average amount of radiation you are exposed to by eating one banana.This latter measurement doesn’t make a whole lot of sense to most people, thus the banana equivalent dose was introduced to give an easy way to understand whether X amount of radiation is harmful or not, given that you know bananas aren’t harmful.For instance, living within 10 miles of a typical nuclear power plant will expose you on a daily basis to just a bit more radiation than you’d get from eating one banana a day.Question: "How does radiometric dating fit with the view of a young earth?" Answer: Radiometric dating does not fit with the “young earth” view.

And as far as major reactor problems that might come up go, if you camped out at the plant at Three Mile Island during the accident that happened there in 1979, you’d have received only an additional 80 millirems of exposure during the duration of the accident.
