Real-time dosimetry is made possible by a personal dosimeter that communicates in real time with the corresponding monitor. Once the badge and monitor are properly configured, it is remarkably simple to use.
Dosimeter
The dosimeter is worn in a preferred position, often on the chest. Depending on the procedure or environment, you can adjust this. It is important to configure this properly in advance via the accompanying software. Here you can set, among other things:
- name of the user
- name to be displayed on the screen
- color display on the screen
- position of the dosimeter: head, hand, torso, abdomen, leg, or other
- function: physician, nurse, technician, or other
- dose limit: any desired value in mSv
- whether or not it is visible on the monitor
- activation setting: off, motion-activated, or permanently on
The dosimeter is automatically displayed on the monitor as soon as it detects movement. The personal badges are battery-operated, and you can replace the batteries yourself if necessary. When the battery is low, this is indicated on the monitor in good time. The dosimeter has a wide measuring range with low angular sensitivity. The RaySafe i3 badges are also compatible with the RaySafe i2 system for real-time dosimetry.
Monitor
The measured dose from the badge is displayed directly on the corresponding monitor. A total of eight badges can be presented on the screen simultaneously. The monitor interprets the measured values and visually indicates whether the value is acceptable, elevated, or too high. This is indicated by green, yellow, or red, respectively. The measured dose is displayed in millisieverts per hour.
- Up to 0.2 mSv/h = green
- From 0.2 to 2 mSv/h = yellow
- From 2 to 20 mSv/h = red
In addition to this color indication, the monitor also displays the total accumulated dose per badge. The highest peak value is also visible as a bar on the screen.
The monitor displays the eight badges with the highest priority. The order is as follows: physicians, nurses, technicians, and then support staff. A total of up to 50 badges can be connected to the RaySafe i3 simultaneously. By pressing a displayed badge on the RaySafe i3 touchscreen, you can also read further information on the monitor, as shown in the image below.
