Radiocarbon (carbon-14), with a half-life of 5730 years, is found throughout the geological record. The confirmation of this fact in the cases investigated in this paper further strengthens the youngearth creationist paradigm. This research broadens the information base by sampling two major CO2 gas fields in Colorado for their carbon-14 content. The results indicate that carbon dioxide data are consistent with that obtained previously from other CO2 and natural gas fields.
