As soon as a living organism dies, it stops taking in new carbon.
The ratio of carbon-12 to carbon-14 at the moment of death is the same as every other living thing, but the carbon-14 decays and is not replaced.
Of course you can find websites that have people from all walks of life, but given that in most cases your time will be precious it makes sense to use our website as you will then have a more narrowed search and so will be more likely to find the right person.
Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).
The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.
The first time we met we were both instantly in love, and very right for one another! The best part was that I found someone who had been severely hurt before so he knows how it feels.
He is even relocating to be near me before we tie the knot.
