The main difference between RaySafe i2 and RaySafe i3 is the dosimeter model:

• RaySafe i3

• RaySafe i2​​​​​​​

The Real-time Dosimeters (i3) have improved performance in sensitivity and directional response, compared to RaySafe i2 dosimeters. See specifications for RaySafe i2 and RaySafe i3 for details.

Note 1: The Real-time Display works with both RaySafe i2 and RaySafe i3. RaySafe Dose Viewer version 1.1.13.0 or later, delivered with RaySafe i3, is backwards compatible with RaySafe i2. Older versions of Dose Viewer need to be updated to support the new dosimeters (i3).

Note 2: RaySafe Real-time Dosimeters (i3) cannot be directly connected to Dose Manager (optional software) via USB cable. However, you can always use network connection or a USB memory stick to transfer stored dose history from Real-time Displays to Dose Manager.

Yes, they can, i2 and i3 dosimeters will show up on DoseAware base station screens and DoseAware dosimeters will show up on the i2 and i3 base stations screens. As the icons used for dosimeters are not the same for i2/i3 and DoseAware, the dosimeters might however appear differently.

The RaySafe i3 has a customer replaceable battery, which prolongs the product life cycle up to 10 years. The RaySafe i2 badge needs to be replaced when the battery ends in <5 years.

Yes, additional badges are available for purchase.

Use Dose Manager (optional software) when you want to:

• Compare dose history from several dosimeters at a time
• Retrieve dose history from Real-time Displays via network
• Produce reports

Please visit www.raysafe.com/products/real-time-dosimetry-systems/raysafe-i3, download and install the latest Dose Viewer that supports i2 and i3 dosimeters.

The EMC immunity in the i3 has been significantly improved over the i2, reducing possible interference.

1. Prolonged life cycle
2. Improved EMC immunity
3. Better measurement specifications
4. Automatic sleep mode
5. Improved wearability.

No, the dosimeter is designed for maintenance-free usage throughout its lifetime.

Yes, you can.

The i3 measurement performance is an improvement over the i2, and includes angular reception making it more accurate.

The Raysafe Real-time Dosimeter: Approximately 1 year of normal use. The battery can be replaced. See the Installation and service manual for guidance.

The RaySafe i2 dosimeter: Typically 3–5 years, depending on usage. If the battery is out, contact your RaySafe representative or RaySafe Support Contact.

Yes, you can combine i2 and i3 badges but be aware that measurement results may differ. We recommend that you replace the i2 badges with i3 ones as soon as possible to ensure comparable measurements.

No, the i3 does not use a cradle like the i2. The improved i3 design lets you just use a USB cable to connect the dosimeter to the computer.

• To access the dose history recorded in the Real-time Display, tap on the row for your dosimeter on the display.
• To access the internal dosimeter memory, connect the dosimeter to a computer running Dose Viewer.

Dose Manager is a software installed on your PC to see the history of dose exposures. You can see a dosimeter’s exposure over time and compare it to other dosimeters. With Dose Manager, you can also collect dosimeters exposure history from the Real-time Display and do not need to connect them individually to your computer. Dose Viewer compared to DoseManager can only show information for one dosimeter at the same time, and the dosimeter must be connected directly to your computer when you look at the history.

The real-time display can be installed anywhere, it only needs a power outlet (network connection is optional). The dosimeters communicate with the display via radio. The radio communication range depends on the local environment and the Real-time Display settings (Service Manual) but is normally about 5–15 meters.

The i3 has improved wearability with a replaceable reinforced plastic clip. The i2 has a metallic clip that cannot be replaced.

No, the intended use for the i3 and i2 systems is to measure scattered radiation only.

Dose Manager can be used with the new i3 dosimeters if you collect the dose information from your Real-time Displays using a network connection or with a USB memory. The i3 dosimeters unfortunately cannot currently be connected directly to Dose Manager by the USB cable.

The dosimeter always measures and stores dose data on its internal memory, regardless of whether there is a display in range or not. You can view the dose history at any time by connecting the dosimeter to a computer running Dose Viewer.

To see the dose rate live, the dosimeter needs to be visible on a real-time display. The dosimeter shows up on any Real-time Display within communication range, it is not paired with a certain display.

The i3 has room for naming, whereas the i2 does not.

The Dose Viewer version 1.1.13.0, delivered with the RaySafe i3, is backwards compatible with the RaySafe i2. Older versions of Dose Viewer need to be updated to support i3 Real-time Dosimeters.

Unfortunately, this is not possible with the RaySafe i2/i3. This is something that we look in to for the future but currently only the Real-time Display can be used to visualize the exposure situation in real time.
