Whether radiocarbon dates should be calibrated depends on one’s purpose. Some studies can be carried out totally in phrases of radiocarbon years. Other studies, similar to those centered on charges of change, may require roughly exact calibrations. In brief, radiocarbon isn’t the be-all and end-all of the issue. Plants absorb radiocarbon, along with regular carbon dioxide, throughout photosynthesis and incorporate it into their tissues.
Some could have mistaken this to imply that the sample had been dated to 20,000 radiocarbon years. The shells of live freshwater clams can, and sometimes do, give anomalous radiocarbon results. However, the explanation for this is understood and the problem is restricted to only a few particular circumstances, of which freshwater clams are the best-known example.

Carbon courting: the day tomorrow began
The effect would be not not like opening a can of soda and having the carbon dioxide fizzing out. The water in these subterranean chambers would not have contained carbon-14, because the water was shielded from cosmic radiation. If the extent 
of atmospheric 14C were constant, this may be simple. In order so far organisms exactly scientists need a reliable historic document of its variation to accurately transform 14C measurements into calendar ages. Radiocarbon holds distinctive potential for the student of earth history who adheres to a recent creation.
