Exploring first responder preferences and opinions about handheld radiation detectors

Handheld radiation detectors are increasingly being used by first responders to scan for and monitor radiological threats. Twenty-two first responders from two different response teams were surveyed about the usability, design, and comfort of handheld radiation detectors. The goal of the survey was to learn how their current detector can be improved and general ergonomic issues that can be enhanced in the design of a new detector. Key areas explored include: operating constraints, detector operational features, buttons, handle, external colour, weight and size, screen functions, and alarm notification. The results provide important user data to study, plan for, develop, and test the design and prototype of an improved detector.
