INSTRUCTIONS FOR USE (EN)
Intended use
RaySafe i3 is designed for personal use on hospital staff. It measures scattered
radiation in examination rooms using a dosimeter, and shows a graphical visualization
of dose rate in real time on a display.
Usage
The RaySafe i3 system needs to be installed and initiated before use. This can be
done by a service technician, using the instructions in the printed Installation and
Service Manual, delivered with the system.
Use the dosimeter on the outside of your X-ray protection garment. Front forward, clip
towards your body.
The Real-time Dosimeter (A in Figure "1." on page 2) measures scattered radiation
and stores measurements. When a dosimeter is exposed to radiation while connected
to a Real-time Hub (B in Figure "1." on page 2), measurements are transferred
from dosimeter to hub via radio. A display shows dose rate bars in real time in green,
yellow or red, from low to high dose rate (C in Figure "1." on page 2).
To view dose history stored in the dosimeter, connect the dosimeter to a computer
running Dose Viewer (D in Figure "1." on page 2). See the Dose Viewer manual,
found in the help menu in Dose Viewer. Optional analysis software: Dose Manager (E
in Figure "1." on page 2).
CAUTION!
The Real-time Dosimeter measures scattered radiation and should
neither be positioned in the primary X-ray field nor be used for
diagnostic measurements.
WARNING!
RaySafe i3 does not replace any X-ray protection equipment.
WARNING!
RaySafe i3 is not sterile.
WARNING!
RaySafe i3 is not a replacement for legal dosimeters.
Maintenance
The Real-time Dosimeter has a replaceable battery. When a red light is flashing on the
side of the dosimeter, the battery needs to be replaced. A service technician can do
this, using the instructions in the Installation and Service Manual.
For cleaning of the dosimeter, use a damp cloth and mild detergent.
