One of the interesting applications of radioactive decay is the technique of radioactive dating.Radioactive dating allows the estimation of the age of any object which was alive once, using the natural radioactivity of .Each isotope is identified with what is called a ‘mass number’.When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.This is called Therefore the characteristic property of the radioisotope, namely its radioactivity can act as a tag or label, which permits the fate of the element or its compound containing this element to be traced through a series of chemical or physical changes.

Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.These use radioactive minerals in rocks as geological clocks.The atoms of some chemical elements have different forms, called isotopes.This is different to relative dating, which only puts geological events in time order.Most absolute dates for rocks are obtained with radiometric methods.

It also allows the estimation of the age of geological samples using the decay of long lived nuclides.

  1. No decisions have yet been made, but school officials plan to look into the possibility of adding radio frequency tags to student or staff ID cards, or place them on school property, like laptops, the New Canaan Advertiser reports.”“The Navy will spend as much as 0,000 to modify a 40-year-old barracks complex that resembles a swastika from the air, a gaffe that went largely unnoticed before satellite images became easily accessible on the Internet.” As the Telegraph reports, researchers at the University of Southampton in the U. have now created a system capable of scanning and analyzing ear structures, which, they claim, are unique enough to accurately identify people.
