RaySafe i2 System User Manual – Introduction How the system works The dosimeter measures and records X-ray exposure every second and transfers the data wirelessly, via radio, to the real time display. The real time display shows real time dose exposure from up to eight dosimeters in range at a time. Color indication bars (green, yellow, red) represents the intensity of the currently received exposure. The accumulated dose per individual is displayed next to the color indication bars.
RaySafe i2 System User Manual – Using the Dosimeter Using the Dosimeter Figure 2. The dosimeter Introduction The dosimeter is an active dose meter designed for maintenance-free usage throughout its lifetime. You can personalize the dosimeter’s appearance by attaching one of the 8 inlays of different color, which are delivered together with the dosimeter. (Select which color to show on the real time display, using the dosimeter options dialog in dose viewer or dose manager.

RaySafe i2 System User Manual – Using the real time display • Dosimeter – a unique ID per dosimeter • Battery status • • 2-4 blocks indicate normal state. • 1 block indicates that the dosimeter needs to be replaced. The dosimeter’s date and time The Personal dose overview has two sub views: • the annual dose view (see section “Annual dose” on page 16) • the personal dose history view (see section “Dose history” on page 17) 1 2 2 3 Figure 8.
RaySafe i2 System User Manual – Using the real time display • Dose session 1 and 2 values, date and time. Use the dose sessions to measure dose for specific time spans, for example a specific procedure or a working day. The value shows the accumulated dose for a session since last dose session reset. Use the reset buttons (2) to reset a dose session to zero. Information about dose session reset will appear as an event in the dose manager software. • Total personal dose since the last dose history reset.
RaySafe i2 System User Manual – Using the real time display • The annual dose limit distributed over the full year (dashed line). As long as the accumulated dose stays below this value, the annual dose limit will not be exceeded for the full year. • Accumulated dose in relation to the annual dose limit for the current year (green/orange line). When the accumulated dose exceeds the distributed annual dose limit, the color will change from green to orange in order to alert the user to take actions.
RaySafe i2 System User Manual – Using the real time display In the day/week time spans you can view accumulated dose value bars. Each bar represents the accumulated dose during one/four hours, respectively. Within the day and week time spans, tapping a dose bar in the diagram will zoom into the larger underlying time scale (that is week -> day and day -> hour). Within each time span (hour/day/week) you can step forward and backward in time with the arrow buttons on the bottom of the screen.
