This restriction extends to animals that consume seafood in their diet.
As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.
Scientists now realize that production of carbon-14 has not been constant over the years, but has changed as the radiation from the sun has fluctuated.
Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.
Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.
It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.
Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.The Half Life is independent of the physical state (solid, liquid, gas) temperature, pressure, the chemical compound in which the nucleus finds itself, and essentially any other outside influence.It is independent of the chemistry of the atomic surface, and independent of the ordinary physical factors of the outside world.
