Real-time Staff Monitoring

The RaySafe i3 real time dosimetry system provides immediate insights about radiation exposure, helping medical staff and physicians quickly evaluate and take action to more effectively use radiation reduction measures.

Since interventional staff have higher radiation exposure than most medical professions due to scattered radiation, real time dosimetry using the RaySafe i3 is a top choice for easily observing, minimizing, and managing radiation exposure without being distracted from the task at hand.

i3 Dosimeter


The RaySafe real-time radiation dosimeter measures and records radiation every second. Data is transferred wirelessly to the Real-time Hub. The dosimeter requires minimal maintenance and can be personalized by removing its window and changing color insets.

Visual Feedback

The RaySafe i3 reveals radiation exposure in real-time using easy-to-read, color-coded bar graphs displayed on the included dedicated display. Green, yellow, and red bars indicate the dose rate for up to eight individuals simultaneously. Instant feedback empowers medical staff to learn and adapt their behavior to minimize unnecessary exposure

Doseviewer display


Measurements are stored for post-procedure analysis in DoseViewer, facilitating continued learning and enabling comparisons over time between labs and between users. For hospitals using multiple i3 systems, advanced analysis, reporting and archiving of dose information is managed through RaySafe Dose Manager.
