How many dosimeters can be shown at the same time on a Real-time Display?
Real-time measurements from up to eight dosimeters are shown simultaneously on the screen. The default order is first come, first serve.
If there are more than eight dosimeters in the room, all of them will still measure and accumulate dose, but only the first eight are visible on the display.
How do I find the dose history?
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.
Can I install the Real-time Display in another room than the lab? What is the communication range of the display?
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.
How do I connect my dosimeter to a computer?
The Real-time Dosimeter (i3) is delivered with a USB cable, to be connected directly to the dosimeter. The RaySafe i2 dosimeter needs a cradle for connection to computer.
I need to re-install Dose Viewer but I cannot find the program. Is it available online?
Yes. Please visit the software page to download and install the latest version of Dose Viewer.
When do I need Dose Manager?
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
Does the dosimeter accumulate dose even when there is no Real-time Display nearby?
Yes, the dosimeter always measures and stores dose data on its internal memory, regardless of if 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.
Can I use the dosimeter for measurements in the primary X-ray beam?
No, the intended use for the RaySafe i3 and RaySafe i2 systems is to measure scattered radiation only.
How long does the battery in the dosimeter last?
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.
Can I name the dosimeters?
Yes, you can set a name for the dosimeter in Dose Viewer and write on the color inlay beneath the plastic shield of the dosimeter.
Can I order spare parts for my dosimeters?
For the RaySafe Real-time Dosimeters, the plastic clip on the back and the label protection window on the front of dosimeter can be ordered as spare parts.
The metallic clip of the RaySafe i2 dosimeter cannot be replaced.
Do I need to send the dosimeter in for calibration?
No, the dosimeter is designed for maintenance-free usage throughout its lifetime.
Can I add more dosimeters to my Real-time Dosimetry system?
Yes, additional dosimeters are available for purchase.
Can we show the same information as on the Real-time Display on any hospital monitor?
This is something that we look in to for the future but currently the Real-time Display must be used to visualize the exposure situation in real time.
Can I use other radio devices, for example my cell phone, near the dosimeter?
RaySafe i3 has good EMC immunity. RaySafe i2 is more easily disturbed, why we don’t recommend using cell phones near RaySafe i2 dosimeters.
RaySafe i3 versus RaySafe i2
What is the difference between RaySafe i2 and RaySafe i3?
The main difference between RaySafe i2 and RaySafe i3 is the dosimeter model:
- RaySafe i2 has RaySafe i2 dosimeters
- RaySafe i3 has RaySafe Real-time Dosimeters
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. Dose Viewer version 184.108.40.206, delivered with RaySafe i3, is backwards compatible with RaySafe i2. Older versions of Dose Viewer need to be updated to support Real-time 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.
Can the RaySafe i2 and RaySafe i3 be used together with Philips DoseAware?
Yes, they can.
Can I use a combination of RaySafe i2 and RaySafe Real-time (i3) dosimeters?
Yes, in theory you can combine RaySafe i2 and RaySafe Real-time (i3) dosimeters, but we recommend using only one type of dosimeter per room to avoid confusion. Since the RaySafe Real-time (i3) dosimeters are more sensitive, they will show more dose than i2 dosimeters.
Are RaySafe i2 dosimeters compatible with the latest Dose Viewer version?
Yes, version 220.127.116.11 and later of Dose Viewer are compatible with RaySafe i3 and RaySafe i2.
