CHAPTER I
CHARACTERISTICS
1.1 - GENERAL CHARACTERISTICS
1.1.1 - Purpose of the equipment
The SOR/R electronic dosimeter is used for measuring
several types of radiation to which the user may be
exposed:
− Ambient and articial X and Gamma,
− Residual Gamma,
It is a rugged equipment specically designed to fulll
the military forces operational conditions.
An original hands-free mode enables the data
exchange with the XOM/R reader even through the
NBC clothes.
1.1.2 - Layout of the SOR/R electronic dosimeter
The SOR/R electronic dosimeter is equipped with a
protective dust and liquid-proof casing.

According to the options selected, it can be tted with a
lanyard for chest wear, a velcro arm band to be worn
over the protective clothing, or a clip.
− The front panel of the SOR/R electronic dosimeter
includes:
• an LCD (A) for data and user id display,
• a pushbutton (B) for data selection and alarm
acknowledgement,
• a smart-card type connector(C),
• a buzzer (audible alarm) (D).
− The rear panel includes:
• battery access via a screwed-on cover (E). The
cover includes a slot for screwing/unscrewing
using a coin or at-blade screwdriver,

− The top of the unit includes a hole for inserting the
lanyard (G) and a fastener (H) for safety release.
A groove is also included for attaching the clip.
1.1.2.1 - Display
The dosimeter can display 6 alphanumeric
characters.

To read the display:
The operator must raise the dosimeter horizontally if
it is worn around the neck.
The operator must hold up his arm if the dosimeter
is worn on the arm band.
1.1.2.2 - Pushbutton
The pushbutton enables display of the following
information:
− The operator's name when pushed once,
− The equivalent dose output when pushed twice
(according to conguration).
It enables cancellation of:
− The lower dose alarm buzzer (pre-alarm) when
held down for over 3 seconds,
− The dose rate alarm buzzer when held down for
over 3 seconds (according to conguration).
1.1.2.3 - Connector
The connector enables connection to the XOM/T
reader-recorder and to external devices.
1.1.2.4 - Buzzer
