RaySafe i3 – 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.
