Why does carbon-14 dating only work for objects that are less than 50000 years old?

After a certain number of half-lives elapses, the remaining amount of carbon-14 is too low to measure with precision. Also, the risk of contamination becomes much greater; i.e., a small contamination will have a larger effect.

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.

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?
Yes, but the dating is only off a little (500 years or so).
Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Too little carbon-14 remains after 50,000 years
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.

carbon 14 dating
What are benefits of using uranium in dating the age of objects?
It is applicable to dating geological samples old from 104 to 2.106 years.
The dating method that can be used in some cases on rocks as young as 50000 years old that contain feldspar mica or amphobole is?
potassium-argon
Why is radiocarbon dating not suitable for dating objects over 50 000 years old?
Radiocarbon dating has a limited range because the amount of carbon-14 in an object decreases over time. After about 50,000 years, there is too little carbon-14 left to accurately measure. At such old ages, other dating methods, such as potassium-argon dating, are more appropriate.
Radiocarbon dating is only accurate for objects no more than?
Radiocarbon dating is only accurate for objects up to about 50,000 years old, as the amount of carbon-14 left in the sample becomes too small to measure accurately beyond that point. Beyond this age limit, other dating methods such as potassium-argon dating or luminescence dating may be used to determine the age of older objects.
