Which risk increases when carbon-14 dating nears its limit?

💡 Explanation

As a sample ages, the carbon-14 concentration decreases due to beta decay; therefore, isotopic fractionation during sample preparation has a larger percentage effect, because it is more difficult to distinguish from genuine age-related changes, rather than instrumental errors.
