The unexplained part has to do with "equilibrium" of the atmosphere. "Dr. Libby’s calculations showed that if the earth started with no 14C in the atmosphere, it would take up to 30,000 years to build up to a steady state (equilibrium)."
A huge assumption, given the known flux of ionizing radiation from the Sun.
We are told: "The Specific Production Rate (SPR) [or the input spout] of C-14 is known to be 18.8 atoms per gram of total carbon per minute. The Specific Decay Rate (SDR) [the output spout] is known to be only 16.1 disintegrations per gram per minute.3"
Given that these statement comprise material facts regarding the subject and there is no error it would seem to me that the amount of C-14 in the atmosphere would be gradually increasing (not going toward equilibrium). Am I missing something? For instance, does the "decay rate" apply only to the artifact and not the atmosphere? <--- that would be my guess, but there are still some questions that arise and it seems we don't have the information needed to determine the right conclusion.
The conclusion that is being examined is based on the idea that if the atmosphere isn't at equilibrium that necessarily means that the earth is less than 30,000 years old. That's what we are being told is the "troubling" part.
The concentration in the atmosphere is known for many thousands of years from lake varves, as Lord Kalvan mentioned.
