The Dragonfly mission will look for signs of prebiotic chemical processes on Titan common to those on Earth. Titan's atmosphere is four times as dense as Earth's atmosphere and is composed primarily of nitrogen (~94%), along with some methane (~5%) and hydrogen. CGR interactions in that atmosphere produce a number of secondary radiations, including neutrons which can then produce 14C via the 14N(n,p)14C reaction. Absorption of 14C into prebiotic chemical processes may serve as a useful tracer to help understand how those processes behave under Titan's environmental conditions. This study uses the transport code PHITS to predict the amount of 14C formed from GCR interactions in Titan's atmosphere.
Heilbronn et al. (Sun,) studied this question.
