I agree, but simply 'older then 50 000 years' as a result (assuming the max age is 50 000 years) would be sufficient to cast doubt on the interpretations creationist do of this data.
Absolutely wrong! Creationist have already used radio-carbon dating on coal in order to claim that it's only 50,000 years old. We already know that creationist lie because we have already heard them use it.
