In fact, the natural production of radiocarbon has varied as well.
The production of radiocarbon has not varied wildly through time, but the changes produce consistent differences from calander ages. These techniques are made possible by sensitive electronic instruments developed in the late twentieth century. A computer program for radiocarbon age calibration. Both methods rely on the ongoing production of radiocarbon in the upper atmosphere. Since the carbon in these fuels was ancient, it contained no radiocarbon. Therefore, prior to atmospheric bomb testing, the proportion of radiocarbon to C was relatively low, giving relatively old ages.

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.
