Morphology
A B1 learner who knows 'crystal' and 'counter' can infer this is a counting device that involves a crystal, so there is some compositional cue. However, the specific technical meaning—an ionization-based radiation detector—is specialized and not derivable from the constituents alone, making the exact function unpredictable without prior exposure.
Etymology
Crystal counter comes from the simple picture of a real crystal that gives a tiny flash when hit by radiation and a counter that counts each flash. So the name refers to 'a device that detects and counts radioactive particles'.
