RaySafe i3, building a better radiation safety culture
The Raysafe i3 dosimetry system is the latest generation of the real-time dosimetry family. The real-time dosimetry system includes a set of the new RaySafe real-time personal radiation dosimeters coupled with a display and software to provide with a complete, immediate visual of radiation exposures.
Visualize X-ray exposure with the new i3 real-time radiation dosimeter using easy-to-read bar graphs. Instant feedback empowers your medical staff to learn and adapt their behavior on the go, minimizing unnecessary radiation exposure.
Measurements are simultaneously stored for post-procedure analysis, facilitating continued learning and to enable comparisons over time, between labs and between users.
Features and benefits
RaySafe i3 offers the following important benefits
Replaceable battery prolonged life cycle
The new radiation dosimeter has a replaceable battery, which means that longevity depends solely on wear and tear.
Better immunity to interference
RaySafe i2 dosimeters are sensitive to certain cell phone signals. The new real-time dosimeter is greatly improved in this regard no interference has been observed during heavy testing.
Automatic sleep mode
Only active dosimeters will populate the screen, regardless of where the inactive units are stored.
Enhanced measurement performance
Wider angular response means that radiation coming from below and from the sides is measured in a predictable fashion. Lowered dose rate threshold results in improved response when used with the latest low dose X-ray machines.

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

Frequently Asked Questions
"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."
