The analysis

The claim states that atmospherically produced carbon-14 undergoes specific radioactive decay and chemical cycling. The retrieved papers include multiple works directly analyzing carbon-14 (radiocarbon) production, global decay processes, and carbon-14 tracing in environmental or biological systems (Papers 3, 5, 7, 8, 11). These sources directly support the premise that carbon-14 is atmospherically produced, undergoes radioactive decay, and participates in broader carbon cycling. No papers refute this well-established physical and biogeochemical principle.
