GAMMAMETER RS04/X
The gammameter, model RS-04/X,
developed and manufactured by BITT TECHNOLOGY,
is designed
for measuring radioactivity of gamma radiation. It is calibrated in "ambient
dose equivalent" units [H*(10)] and its measuring range comprises 9 decades
(from 10 nSv/h up to 10 Sv/h). This wide measuring range
permits
detecting minor changes in the ambient natural radioactivity as well as
measuring high dosage rates.
MAIN
APPLICATIONS
This robust and
unique detector lends itself to
an extensive
range of
utilizations:
 | sensor in monitoring network
for early warning system covering a wide area; |
| hospital surveillance at
radiation therapy wards;, |
| measuring unit in scientific
institutions and development centres, |
| supervision unit at borders,
airports, railway stations and in aircrafts, etc., |
| control unit in municipal
sector mainly for the instant check of accidental radiation, generated by
nuclear |
| industry (nuclear power
plants, storage
of fusionable material and truck/train transportation of such materials), |
| measuring unit in private
sector, especially for owners of fallout shelters. |
TECHNICAL CONCEPT
The detector operates at 12 V, abt, 50 mA DC. To evaluate the
measured data a personal computer and a serial interface (RS232, RS485; optional
USB) are required. The serial interface type RS232 permits a distance between
the detector and the evaluating unit of up to 1.500 m, while the type RS485
allows for up to 5000 m.
STRUCTURE OF THE DETECTOR
|
The BITT Technology detector is a proportional counter tube
of type NPGD02. A large number of these counter tubes have been in operation
in several European countries for many years and have set new worldwide
environmental surveillance standard. This specific model is unique as it is
the only one that is able to cover a 9-decade measuring range with a single
detector. |
|
One of the major advantages is that the counter tube's
sensitivity to natural ambient radiation is rather high despite its wide
measuring range. The tube’s durability is practically independent of the
number of pulses. |
|
The signal processing unit was developed on the basis of
extensive experiences gained over many years. |
|
The microprocessor unit processes the signals from the
counter tube, converts them into dosage rate units, continuously checks the
operational data of the detector, stores the measured data and provides
communication between the detector and the central unit. |
|
An extra stable high-voltage unit ensures the solid
operation of the counter tube. |
|
Additionally all electric in- and outputs are equipped with
special protection filters (NEMP+++) providing excellent lightning
protection. |
|
The complete equipment of the detector is housed in a
waterproof aluminium tube with a wall thickness of 2 mm. The connector is
also waterproof. |
