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).
  • Large Scale:
    GAMMA-SCOUT® is calibrated across a wide scale (0.01 up to 5000.00 µSv/h).
  • Tested Calibration:
    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
    personal charts.

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. radon 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.

Geiger Counter

Questions and answers about Geiger counters.

If you own a Geiger counter, you will soon come across some terms that a Geiger counter owner has to deal with. There are complex relationships between the voltage activities to be measured and the properties of the respective device type. The following is a brief overview of the most important units involved in the topic of radioactivity. This way you can be sure that you interpret the numbers on the display correctly and then draw the right conclusions.

The unit of measurement Becquerel indicates how many atomic nuclei of a radioactive substance decay within a second. The half-life is the probability that an atomic nucleus will decay in the next second. If you want to determine the total activity of a substance, you multiply the amount of atomic nuclei that decay in one second by the number of atoms present.

Dose rate
The dose rate indicates how much energy is stored per unit of time in a defined quantity of substance. In order to describe the harmful potential of radioactivity, the pure activity information is not sufficient; it must also be stated how much energy is deposited per unit of time in a substance. The dose rate is measured in joules per kilogram and second.

In medicine, on the other hand, people are not only interested in the energy that is deposited in a substance in a time interval, but above all in the biological damage it causes to human tissue. Since different types of radiation with their different energy ranges have a different damaging potential, the dose rate is weighted by a biological factor. The result is the so-called equivalent dose rate, measured in Sievert per second (Sv/s). The higher the equivalent dose rate, the higher the tissue-damaging potential of radiation.

Since one sievert per second already corresponds to a very dangerous irradiation, the tissue-damaging potential is often indicated in microsievert per second (µSv/s). For longer stays in radiating areas the radiation exposure is also indicated in microsievert per hour (µSv/h).

If the dose rate is added up over a period of time, the dose is obtained. The dose is given in Gray or Sievert. A flight from Berlin to Los Angeles, for example, produces a dose of 50 to 100 microsievert (µSv), which corresponds approximately to the dose produced by an X-ray of the chest. According to the Federal Office for Radiation Protection, the total effective dose of X-ray examinations is 1.6 millisievert per person per year in Germany (mSv).

Annual dose
The annual dose for natural radiation in Germany is about 2 millisieverts per year (mSv/a). The annual dose can vary greatly for individual citizens, depending on their place of residence and lifestyle. The annual maximum dose for persons who are exposed to radioactive radiation in their profession is 20 millisieverts per year (mSv/a) in Germany. In the USA, the limit was set at 50 millisieverts per year (mSv/a). Even if the maximum annual dose here is quite high, it is worth keeping the annual dose as low as possible.

A Geiger counter measures the number of radioactive decays of a substance. The value shown on the display is the higher the more decays a material produces. If the radiation meter has a ticker, the radiation intensity can even be made audible. The shorter the distances between the individual clicks, the higher the decay rate.

The most important component of a Geiger counter is the so-called Geiger-Müller counter tube. This consists of a metal shell, a cathode and an anode. The tube itself is filled with a gas (often inert gas). If the thin wire in the middle is now energized (500 volts or more), it can attract the electrons that are released when radioactive particles disintegrate. The contact of electrons with the inert gas of the Geiger-Müller counter tube makes the gas briefly conductive, thus closing the circuit. If the Geiger counter has a loudspeaker, a click sound is generated during this process.

In addition to the Geiger meters with Geiger-Müller counter tube, there are also models with semiconductor detectors. These models can not only determine the number of decays of a substance, but also the energy of the incident radiation. In addition, Geiger counters based on semiconductor technology have a very long service life and low energy consumption.

The radiation measuring device Gamma-Scout Standard is known for its particularly high-quality counter tube, which cannot be found in such a quality in any other comparable device. This is the reason why not only employees from science and research as well as from authorities and industry turn to Gamma-Scout, but also more and more laymen who want to get more certainty about a possible radiation exposure in their environment. The Gamma-Scout Standard is used, for example, to check:

  • Residential and office buildings
  • Walls, ceilings and floors
  • Building materials and natural stones
  • Postal consignments, on receipt of goods
  • Parcels and letters at customs
  • Radon concentrations in residential buildings etc.

Since the Geiger counter Gamma-Scout constantly adds up all measured values, the radiation measuring device can also be used as a dosimeter. In this way you can determine the total dose that hits your body in a certain period of time. Afterwards the measured values can be compared with the recommendations of the Federal Office for Radiation Protection.

Natural radiation is constantly present in our environment. The normal level of underground radiation is about 0.1-0.25 µSv/h on average worldwide. So if the measurements with your Geiger counter show higher values, this is already a problem. The seriousness of this problem then only depends on two further factors: The time you have been exposed to the radiation and the amount of radiation dose.
