Morphology
The meaning is directly compositional: 'dating' means determining an object's age and 'radiocarbon' specifies the carbon-14 isotope used for that purpose, so the compound denotes the method of dating using radiocarbon. This follows a common noun+noun composition pattern (method + instrument/source) and would be understandable to a B1 learner who already knows both constituents, despite being a technical term.
Etymology
Radiocarbon dating uses a tiny natural 'clock' inside once-living things. The name comes from using radiocarbon, a kind of carbon called carbon-14, to find the 'date' of an object, because carbon-14 slowly disappears after death.
