https://en.wikipedia.org/wiki/Carbon-14#Natural_production_in_the_atmosphere focuses upon the two uppermost layers because if the radiocarbon dating is incorrect then Layer A [1006 ± 67 AD] might be associated with the Heinsohn Horizon [around] 914 CE whilst Layer B [925 ± 76 AD] might be associated with the Sand Layer [around] 760 CE.NASA copyright policy states that "NASA material is not protected by copyright unless noted".apparently accept radiocarbon dating as the gospel truth.However, if the Settled Science that supports radiocarbon dating is really just one huge homogenised hodgepodge then acquiescent Earth Scientists are simply being misdirected and left to flounder in the dark.An improved method and system of pulsed mode operation of ionization chambers in which a single sensor system with gamma compensation is provided by sampling, squaring, automatic gate selector, and differential amplifier circuit means, employed in relation to chambers sensitized to neutron plus gamma... .,760,l8 eisse 8 Claims, 15 Drawing Figures T PREAMP .28 .30 .32 .34 l r J H, DIFFERENTIAL LINEAR 263" PL A Y PULSER AMPLIFIER GA TE HOLD 20 A PREAMP 3 He 26 SIGNAL IS INVERTED IN THE PREAMP PIC SYSTEM FOR GAMMA COMPENSATION MASTER CLOCK SIGNAL 377 CHARGING NET WORK GATE 54 PULSED HIGH 48 VOLTAGE SIGNAL PIC VOLTAGE 7O SIGNAL OUTPUT TRACK a HOLD I468 SAMPLE SIGNAL I47 HELD SIGNAL LEVEL 728/08 ROUTING GATE 74 DIFFERENCE} SIGNAL 9a DISPLAY MODE SAMPLE GATE203 MODE SELECTION SAMPLE GATE 20!An improved method and system of pulsed mode operation of ionization chambers in which a single sensor system with gamma compensation is provided by sampling, squaring, automatic gate selector, and differential amplifier circuit means, employed in relation to chambers sensitized to neutron plus gamma and gamma-only to subtract out the gamma component, wherein squaring functions circuits, a supplemental high performance pulse rate system, and operational and display mode selection and sampling gate circuits are utilized to provide automatic wide range linear measurement capability for neutron flux and reactor power and wherein neon is employed as an additive in the ionization chambers to provide independence of ionized gas kinetics temperature effects, and wherein the pulsed mode of operation provide independence of high temperature insulator leakage effects.

Sadly, this hybrid, high jacked and half-baked Settled Science has now degenerated into a recursive [incestuous] feedback loop where dendrochronology calibrates Radiocarbon Dating which, in its turn, is used to calibrate dendrochronology.
See: Carbon 14 - Libby's Ring Amongst the many issues associated with the Settled Science of radiocarbon dating there is the curious case of Catastrophic Cometary Carbon-14.
The previous and current modes of operation of ionization of gas filled chambers that have been used for such purposes have taken the form of steady state ionization current operation, pulse rate modes in which chambers are operated in the ion chamber or proportional modes, and more recently the so-called Campbelling technique of operation.
Each of these modes, other than the Campbelling technique, have their own unique limitations which restrict their use to fairly narrow ranges of reactor operation.Similarly, meteors will generate radionuclides in the atmosphere.
