SAFETY INSTRUCTIONS
Do not use the unit if error messages appear on the screen.
The earphone connector at the bottom side of the instrument
must be exclusively used by equipment that is specified for
use with RadEye SPRD.
The instrument must not be used in explosive atmosphere.
The RadEye SPRD is not intended to be used as a personal
dosimeter. No neutron dose rate or dose calculation is per-
formed. Due to the high detector sensitivity the gamma dose
rate measuring range of the RadEye SPRD is limited to
250 µSv/h (25 mrem/h). For higher dose rates (indicated by
“Overload”) an underestimation of the integrated gamma dose
can be expected.
The RadEye SPRD shall not be used for measurements in
pulsed fields.

1. Introduction
The RadEye SPRD radiation pagers are highly sensitive and
rugged measuring devices to detect and localize gamma and
neutron radiation sources.
Furthermore, by virtue of the so called NBR-technique (natu-
ral Background Rejection) the RadEye SPRD pagers separate
man-made (non-NORM1) gamma radiation from natural back-
ground fluctuations. As well, the energy compensated dose
rate of gamma radiation (Sv/h) can be measured. In this con-
text it is important to note, that users may select “R/h” as a
display unit, with the understanding that the energy response
characteristic is not altered by this selection. Within the Rad-
Eye SPRD the relation 1 R = 1 rem = 10 mSv is used.
The instrument is designed to meet the requirements in the
ANSI standard 42.48 in respect to gamma radiation.

Natural Occurring Radioactive Material (NORM).

The RadEye SPRD incorporates a single CsI (Tl) Cesium Io-
dide Scintillator which is equipped with a miniature silicon
photo-multiplier (SiPM) allowing the detection of very low
radiation levels.
While the RadEye SPRD does not contain a specific thermal
neutron detector, it does analyze specific characteristic fea-
tures of the measured gamma spectrum to indicate the pres-
ence of a neutron source.
The RadEye SPRD pager identifies to the user whether the
alarms are due to gamma or neutron by a different colored
alarm LED, different tones and flashing the count rate / dose
rate display readings with an inverted display background of
the alarming channels or both channels as appropriate. The
RadEye SPRD also has different audible alarms discriminating
between elevated background/NORM and any artificial iso-
tope alarm also the gamma and neutron audible alarms are
clearly different. This gives the RadEye SPRD audible and
visual identification using NBR of the type of material de-
tected.
The last 1600 mean and maximum values of gamma count
rate, neutron count rate and gamma dose rate data points are
recorded internally and can be read out via serial interface.
Additionally the last 250 alarms, errors and changes of the
configuration are logged. All events can be read out via serial
interface.

A real time clock is provided to add a time stamp to all buffer
data.
The RadEye SPRD enables measurement of detector pulse
rates and energy compensated dose and dose rates.
All menu functions described in 3.4 can be configured to be
invisible.
Thus the instrument can be configured to both, an extremely
simple mode allowing just LCD-illumination and alarm ac-
knowledgment to a very versatile mode for the more experi-
enced user.

2. Installation and start-up
2.1 Scope of delivery
The RadEye is delivered in a folding paper box together with
two AAA cells, a rubber protection sleeve and an operating
manual.
For optional accessories see chapter 12.

2.2 Inserting the battery
The two AAA-Alkaline cells as delivered with the instrument
allow est. 170 h of normal operation.
AAA size rechargeable batteries can be used as well.
•Switch off the measuring instrument and wait about 5s for
complete shutdown.
•Remove rubber boot.
•Open the cover of the battery compartment.
Use of a coin is recommended.
•Exchange the batteries according to the shown polarity.
•Close the compartment cover hooks first, care for the rub-
ber seal being in its groove.
•Switch on the unit again. (see chapter 2.4)
The instrument continues working in the operating mode set
last (see chapter 3.2).
