Morphology
The compound is directly compositional: 'ionization' denotes the process of producing ions and 'chamber' denotes an enclosed space, so the phrase straightforwardly refers to a chamber where ionization takes place (commonly used to detect radiation). This noun–noun compounding pattern is standard and cross-linguistically familiar, so a B1 learner who knows both constituents can grasp the basic meaning even if technical details require specialist knowledge.
Etymology
Ionization chamber gets its name from what the device does: radiation makes tiny charged bits inside a gas-filled chamber, and the device detects those charges. So the parts ionization (making 'charged particles') and chamber (a closed space) explain why the phrase means 'a tool that measures radiation'.
