This restriction extends to animals that consume seafood in their diet.
C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.
The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.
Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
When these energetic neutrons collide with a nitrogen-14 (seven protons, seven neutrons) atom it turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).
Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.
Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).
This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
These two measures of time will only be the same if all of the assumptions which go into the conventional radiocarbon dating technique are valid.
