Short Answer:

Carbon 14 dating can only be used on objects which were once living things (plant or animal). Typically, the object must be less than 50,000 or so years old. Otherwise the carbon 14 has decayed to such a low level that the detection becomes difficult.

More:

Living creatures constantly exchange carbon in their bodies with carbon from the atmosphere and so the isotopic concentration of carbon 14 in a plant or animal is the same as the concentration of the atmosphere. That stops, of course, when the creature dies. Since carbon 14 is radioactive, the fraction of carbon 14 in the remains of the creature will decrease over thousands of years. By measuring how much is left, the date the the creature died can be measured with some degree of accuracy.

An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?

To determine the age of the artifact, you can use the formula for exponential decay of radioactive elements: (N = N_0 \times (1/2)^{t/T}), where N is the final amount (3.1% of the original), N0 is the initial amount (100%), t is the time passed, and T is the half-life (5730 years). By substituting the values, you can solve for t, which will give you the age of the artifact.


Which type of dating method was used and which type was not used?

Radiometric dating methods, such as carbon dating, are commonly used to determine the age of organic materials, while relative dating methods, like stratigraphy, assess the age of materials based on their layer positioning without providing a specific age. In contrast, dendrochronology, which analyzes tree rings to date events and environmental changes, is also a form of dating not utilized in this context. Therefore, radiometric dating was used, while dendrochronology was not.


Which kind of dating can be used to determine the exact age of the rock and which kind of carbon dating is used to compare the ages of rocks?

Radiometric dating, specifically uranium-lead dating, can be used to determine the exact age of a rock by measuring the decay of uranium isotopes into lead over time. In contrast, carbon-14 dating, a form of radiocarbon dating, is used primarily to date organic materials and can provide a comparative age for rocks containing fossilized organic matter. While carbon dating is effective for younger samples (up to about 50,000 years), it is not suitable for dating most rocks directly.

What Limitations are there of using carbon14 to date rocks?

The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.


A researcher who uses carbon dating on anciet items?

The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.


What do scientist know about Carbon12 Carbon14 atoms?

Scientists know that the isotopes Carbon-12 and Carbon-14 are both forms of carbon, but they differ in the number of neutrons they contain. Carbon-12 is the most common form of carbon and is stable, while Carbon-14 is radioactive and is used in radiocarbon dating to determine the age of organic materials.
