See and reduce your radiation exposure.

The RaySafe i3 is an active dosimetry system that provides real-time insights about radiation exposure, helping medical staff and physicians evaluate and directly adjust their behaviors and more effectively use all the radiation reduction solutions provided in the room.

Interventional staff have higher radiation exposure than most medical professions, because of scattered radiation. Use the RaySafe i3 to easily observe, minimize, and manage radiation exposure without being distracted from the task at hand.


Real-time View

Real-time View, shown on the lab's main screen or on a stand-alone display, shows dose data for connected dosimeters in real time. Green, yellow and red bars indicate the dose rate for each individual.

Real-time Dosimeter

The Real-time Dosimeter measures and records radiation every second. Data is transferred wirelessly to the Real-time Hub.

A USB connector connects the Real-time Dosimeter to the Dose Viewer software, which can be used to change settings and to view and export dose data. The dosimeter is easy t wear, requires minimal maintenance and is made to be personalized.   



Dose Viewer is used for administrating dosimeters and viewing personal dose information. For advanced analysis, reporting and archiving of dose information, use Dose Manager. It manages multiple dosimeters and can retrieve dose information from multiple i3 systems throughout the hospital network or via USB storage. 

RaySafe i3 Software


RaySafe i3 comes in two different configurations – RaySafe i3 with Stand-alone Display and RaySafe i3 with On-Screen Display.

Radiation Safety

Radiation Safety

Radiation protection is important because:

  • Radiation exposure from medical procedures has increased dramatically during the last few years

  • Interventional cardiologists receive the highest amounts of radiation among medical personnel

  • Radiation exposure can be reduced significantly by optimizing behavior and by using protective devices

ABCs for a Radiation Safety Culture™


Protective clothing and devices, such as lead aprons, thyroid collars, glasses, ceiling suspended screens and table-mounted lead curtains, are the first line of defense against radiation exposure. Personal dosimeters are used to monitor and help regulate exposure.

Your behavior will affect your radiation exposure. When feasible, increase the distance and decrease the exposure time. Furthermore, scatter radiation is typically lower on the detector side.

Finally, ensure that the proper equipment and appropriate techniques are used, including collimating the X-ray beam.

Ultimately, controlling your dose is easiest when it is known. Only an active dosimeter, such as RaySafe i3, provides constant, real-time radiation exposure information. With the information it provides, healthcare workers can take action to reduce their dose.

Dose Viewer works with the RaySafe i2 and i3 dosimeters when connected with a computer to display and analyze stored measurements and change dosimeter settings. 

RaySafe Dose Viewer lets you: 

  • View stored measurements, such as these, when the dosimeter is connected to a computer: 
    • Dosimeter ID number Battery status 
    • Accumulated dose 
    • Dose rate 
    • Time period 
  • Change dosimeter settings including name and annual dose limit 
  • View in a graph or a table format

"The improvement in radiation protection has been more than dramatic at the URMC. There is no substitute for a constant and real-time reminder of the dose being received."

-Labib H. Syed, M.D., M.P.H.
University of Rochester Medical Center

"We feel better about our work and our safety. Now that we see what RaySafe real-time dosimetry does for us, we wouldn’t want to work at a place that doesn’t have it.”

-Dawn Dowling, Technologist
