The Types segment classifies exposure meters by operational principle and form factor, encompassing Passive (integrating) devices, Active (real‑time) devices, and within each, sub‑categories such as handheld, fixed‑mount, and network‑enabled units. Passive meters, which accumulate dose over time, hold roughly 35 % of market volume, favored in long‑term monitoring where periodic readout suffices, such as personal badge programs in nuclear facilities. Active meters, delivering instantaneous dose‑rate readouts, capture about 45 % of revenue, driven by high‑risk environments that demand immediate alarms, including interventional radiology suites and emergency response teams. Handheld models, comprising 30 % of the type mix, provide portability for spot checks, whereas fixed‑mount systems, accounting for 25 %, are installed in controlled zones to deliver continuous surveillance. Network‑enabled devices, increasingly integrated with IoT platforms, represent the remaining 20 % and enable centralized data analytics, predictive maintenance, and compliance reporting, thereby adding a strategic layer to the market’s value chain.
