What is one limitation of radioactive dating?

See explanation.

Explanation:

Radioactive dating, also known as carbon-14 dating, has some limitations. This technique can theoretically provide the age of something that was once alive. This method does not work with inorganic items such as tools made of stone or pottery that is made with something inorganic such as ceramic materials.

One limitation of this type of dating is that the amount of carbon-14 is less and less the older something is. This means that there is less and less to measure. This usually means there are limits of about 60,000 years with respect to the age that can be measured by this method.

Another limitation has to do with contamination with other items. For example, if there are items that might affect the carbon-14 dating in the sample, the item might measure as being much older than it really is. Substances that might contaminate the sample include coal. There might be other items that include older sources of carbon.
