Center”. Your device is easy to use and can be applied for
household purposes without special training of the user.
Should any questions arise, please contact our managers by
telephone [phone], fax [phone]
or e-mail [email protected].

Best regards, International Sales Department

Dear users,
We would like to draw your attention to the delivery kit of
the UDKG-01A “Gamma Sapiens” intellectual gamma radiation
detector that includes two AAA batteries. However, the power
for operation can also be supplied by two ААА nickel-metal-
hydride (NiMH) rechargeable batteries of no less than 800 mАh
capacity instead of batteries that come with the device. You can
buy these rechargeable batteries and their charger at any retail
outlet. Famous manufactures, such as Varta, are highly
recommended.
Choose an automatic battery charger, preferably with a
function to control charging of each rechargeable battery.
Charge rechargeable batteries only when they are fully
discharged. Recharging partially discharged rechargeable
batteries on a repeated basis minimizes considerably their
lifespan.
Do not use one rechargeable battery along with a non-
rechargeable one to power the gamma radiation detector. This
will lead to the rechargeable battery failure.

1.4 Design and principle of operation
1.4.1 General information
The detector is presented as a monoblock
construction with a built-in sensor of gamma
radiation (the Geiger-Muller counter), a printed-
circuit board with electronic components, and
batteries.
The operation principle of the detector is based on
transformation of radiation by the Geiger-Muller
counter into the sequence of voltage pulses; the
number of pulses is proportional to the registered
radiation intensity.
The power for operation is supplied by two AAA
batteries.

14
1.4.2 Design description
The detector is designed as a flat square plastic
housing with rounded corners.
The housing (Figure 1) consists of the front (1)
and the back (2) covers.
On the right side of the front cover there is a disk-
shaped control and indication board (3) with a
decorative circle frame (4) around. The window (5)
for two-color LED indicator and the control
button (6) are also located in that area.
The battery compartment (7) for two AAA
batteries is in the middle of the back cover. The
polarity signs are indicated at the bottom of the
battery compartment (7) for proper insertion of
batteries. The battery compartment is closed with a
lid (8).
A clip with an opening (9) fixed to the back cover
is used to attach the detector to a strap.
