Dear users,
We would like to draw your attention to the delivery kit of the
UDKG-01A (UDKG-01APro) “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, arehighly recommended.
Choose an automaticbattery charger, preferably with a function to
control chargingof each rechargeablebattery.
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.

16
1.4.2 Design description
The detector is designed as a flat square plastic
housing with rounded corners.
The housing (Figure 1, 2) 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.
