GAMMA-SCOUT® ONLINE / REAL TIME (with the functions of the Alert-model)
Used in Measurement Stations:
GAMMA-SCOUT® sends measured impulses in a 2 second interval
(synchronized with the measurement ) via USB-Port to a connected PC.
Threshold for Dose Rate:
This model features an acoustic alert when radiation level exceeds a user programmed threshold..
Threshold for (cumulative) Dose:
GAMMA-SCOUT® w/ALERT offers an acoustic alarm when a user programmed threshold for the
cumulative dose is exceeded.
The user can set an acoustical ticker which activates with each gamma pulse detected.
To save battery resources, the signal shuts down after ten minutes and must be restarted.
On devices with rechargeable batteries, the ticker will not shut down.
Functions and Features (all models)
Large range of calbration:
In measuring mode, the display shows the current radiation measurement reading.
The display also temporarily shows the average H of the last day (24h, 12 am to 12 am).
GAMMA-SCOUT® is calibrated across a wide scale (0.01 up to 5000.00 µSv/h).
Each GAMMA-SCOUT® radiation meter is subjected to a final test. This test is supervised by
the Institute of Radiation Protection; a government controlled university for Applied Technology.
The tested device must be in a confidence interval of 5% in comparison to a master.
This master is adjusted to a gauged reference Cs-137 emitter.
Reference Isotope Not Equal to Cs-137:
The conversion from impulses per time into the dose rate is based on Cs-137. If other isotopes
are present, the impulses per time can be directly displayed, and can be converted by using
Dose Rate and Dose:
GAMMA-SCOUT® can be used as a dose meter (cumulative radiation).
Change Sievert to Rem:
The dose rate may be displayed in Sievert or Rem.
Energy-Saving Permanent Operation:
The GAMMA-SCOUT® monitors radiation day and night and logs data for later download.
Due to sophisticated electronics, its battery lasts for years. The model “RECHARGEABLE” works
with a rechargeable battery.
GAMMA-SCOUT® stores all registered pulses in its internal memory and keeps them ready for you
to use when desired. 110,000 Readings: For constant monitoring of the environmental data, the interval
of data storage is set on a value of one per week. This equals 600 years of memory capacity.
The user can set up smaller intervals, which maxes out the memory capacity sooner.
To clear the memory content, see the manual.
GAMMA-SCOUT® meets all European CE standards as well as the
“FCC 15 standard” of the USA. GAMMA-SCOUT® may be carried on aircraft.

Leading Gap - What makes Gamma-Scout superior in comparison to other Geiger counters?
There are a variety of Geiger counters available on the market today. What makes Gamma-Scout a superior product?
There are many reasons why, see features. Some of these features are emphasized below:
1. The core component of every Geiger counter is a Geiger-Müller counter tube. Among experts, the best known counter
tube of small dimensions is a product made in the USA (LND Incorporated). It is high-priced, but of high
quality. Gamma-Scout operates with this counter tube, which can also measure alpha radiation (e. g. gas/plutonium).
Lower-priced Geiger counters use counter tubes of lower quality and can only measure gamma radiation.
2. The health risks caused by increased radiation are particularly high for long-term exposure. This is the reason
why the Radiation Protection Ordinance does not feature short-term threshold values, but names
20 millisievert/year (=20,000 microsievert/year). For daily monitoring, it is practical to downscale the annual
value into an hourly value (to measure by minutes and seconds), but its main purpose is still to control the
cumulative value (cumulative dose). For this purpose, the device has to count and accumulate the values over
a long period of time, which is not possible if the Geiger counter only operates for an hour and is then
switched off. For continuous measurement, the battery needs to last for a long period of time. Therefore,
the device needs to have extremely low power consumption. The Gamma-Scout’s power consumption is so low
(approx. 10 microampere in basic operation mode) that the battery lasts for many years.
Physicists say that the determination of additional radiation exposure is only possible through long-term data
accumulation. Additional radiation exposure easily doubles people’s annual exposure
(from approx. 2 to 4 mSv/a) and occurs through, e.g., medical devices, flights (5 to 10 µSv/h, which is 25x to
50x higher than normal ambient radiation), and through vacations in higher altitudes or at
monazite-impregnated sand beaches.
To accomplish solid measurement results for these low radiation levels, the measurement time should be
at least several hours, or even better, several days.
3. Some users criticize that Gamma-Scout‘s battery is not removable, but soldered to the device. There is a
good reason for this: With a removable battery, extremely low power consumption used by Gamma-Scout
would cause oxidized contacts , resulting in immediate contact interruption. This is why an uninterrupted
connection is indispensable.
4. The concept of Gamma-Scout, to operate with constant data accumulation, carries the important technical
advantage that semiconductors remain more stable in comparison to devices with operation interruptions.
5. There may be potential customers who are not interested in advanced features such as alpha radiation
measurement, data accumulation, impulse rate measurement, REM measurement, etc. Some people may
prefer a simple solution; a less sophisticated, lower priced (switch on, read, switch off) gadget. For these
potential customers, we have developed the Gamma-Easy available at the lowest
price level one can offer for Geiger counters with reasonable measurement.
