Description
Radon measuring devise RadonTec RadonEye RD200
Now measure radon quickly and easily with the RadonEye from RadonTec. Thanks to the ionization pulse chamber (which is actually only available in professional devices), the measuring device is the fastest and most accurate radon measuring device for private users on the market. Each meter has been individually checked and calibrated.
The display shows the current radon value (in 10-minute intervals) and via the smartphone app (available for Android and iPhone), you can view the exact radon value of the complete measurement (resolved in time).
It is also possible to define a radon alarm value, if this is exceeded, the measuring device warns with a visual and acoustic alarm.
Radon measurement cannot be faster, safer and easier.

All the plus points of the RadonEye at a glance
- Fast measurement: The first reliable measured values can be read from the OLED display after just 1 hour and then every 10 minutes thereafter. Other measuring devices usually deliver first results only after a measuring period of 24 to 48 hours.
- Easy radon measurement: Thanks to easy-to-understand operating instructions, you can easily determine dangerous radon levels in your home. Hourly readings are stored for up to one year.
- Free app for Android and iOS: Get a long-term overview of the measured values through the graphical display (cell phone) or as a data series (download file).
- Very high measurement accuracy: The RadonEye clearly stands out with a 20 times higher measurement sensitivity than comparable devices within this price range (deviation clearly < 10%). The high-quality device is a smart as well as highly sensitive radon detector with professional ionization pulse chamber Technology.

FAQ (17)
Radon in general
1. Correct placement of the measuring device
- at least 25 cm from the nearest wall
- at least 50 cm above the floor
- at least 150 cm from the nearest window, door, radiator or ventilation slits
- no direct sunlight
- protect from dripping water or moisture
- rooms with ground contact (soil) tend to have a higher radon load
- dormitories, hobby rooms or children's rooms (rooms with a long stay) should be at the top of your list of measurements
- place your measuring device where you "breathe" I.e. at your desk at head level, in the bedroom on the bedside table, in the hobby or sports room at eye level.
2. Pay attention to weather and environmental influences
Radon values are subject to strong fluctuations. Especially the weather and also the season have a strong influence on the measured radon values. For this reason, we recommend that passive long-term measurements are always carried out in parallel to the short-term measurements.
In summer the measured values tend to be lowest. In spring and autumn you (usually) get a good average value of the average exposure over the annual average. In winter the measured values tend to be higher due to:
- worse ventilation behaviour
- frozen floor / walls, which become more permeable to the radon gas
- Chimney effects in the house (through strong heating)
For this reason, it is recommended that at least part of the measurements (long-term measurements) be taken in spring or autumn.
3. Measurement duration for radon measurements
The longer the measurement period, the more accurate the measurement result. Air pressure, humidity, temperature, wind, rain, sun can also have an influence on the measured radon values. For this reason, a measurement duration of at least 7 days per room is recommended (for short-term measurements). Short-term measurements are good to get a first impression of the current situation, but in addition to short-term measurements, long-term measurements over several months should also be carried out.
4. Extreme value measurement
If you want to carry out an extreme value measurement at your home, you should not enter the room or ventilate it for days before the actual measurement. During the measurement, the room should also not be entered or ventilated. In this way you can determine your maximum radon exposure.
5. Realistic radon value
In order to get the best & realistic average value of your radon exposure, you should continue to use the desired room as usual. This means that you should not change your habits (door open/closed, ventilation behaviour, usage behaviour) during the measurement. It is best to start the measurement and simply ignore the measuring device for the next few days. This will give you a radon value that reflects the real exposure (but please also consider point 2, that e.g. in winter your ventilation behaviour can change).
6. Typical measurement errors when measuring radon
- Measuring time too short
- Changing the position of the measuring device during the measurement
- Wrong measuring point
- Other use of the room than usual (in the case of extreme value measurement this is done intentionally)
Normally, the radon levels are highest in the basement rooms and decrease with each additional floor. However, due to structural conditions (gaps in the walls, chimneys, electrical ducts, water supply shafts, ventilation shafts, heat insulation cladding, etc.) chimney effects can occur, which literally suck the radon gas into the upper floors. Only a measurement in the respective rooms can give you certainty.
7. Measurement results of the neighbour
Measurement results from your neighbor or measurements that have been taken in your area cannot give a reliable statement about your own radon exposure in your house. Radon can change from little to extremely much within a few meters due to different soil layers (clay, gravel, groundwater, etc.). Also the characteristics of each building (tightness of the floor slab, walls, pipe penetrations) are individual. Likewise, the ventilation behaviour and the use of space are different. Our recommendation is therefore clear, that only your own measurements can provide real information about your personal radon situation.
Radon is a radioactive pollutant which occurs as a natural gas and escapes from soils and building materials. Radon penetrates through the cellar walls and the cellar floor into houses, where it can accumulate considerably due to poor ventilation.
Via the air we breathe, we transport the radon and its radioactive secondary products into our lungs, where they can cause considerable damage through radiation. This is why radon is now cited as the main cause of lung cancer after smoking.
Radon is a naturally occurring gas from which one can protect oneself with the right measures. That is why the correct handling of it is all the more important.
The radioactive gas radon decomposes into decay products, which are also radioactive. The short-lived decomposition products can subsequently adhere to dust particles (aerosols) in the room air, which cause them to be inhaled by humans. Once the radioactive particles are in the lungs, some particles are deposited in the lungs. The radon gas itself is largely exhaled unchanged.
So it is not radon itself that poses the greatest danger, but its decay products. The inhaled radioactive particles emit high-energy, ionising radiation during decay, which can directly damage the lung tissue. This promotes and promotes the development of lung cancer.
How high is the risk of lung cancer?
Population studies show that the risk of lung cancer is directly related to the level of radon gas concentration in the ambient air. In the fresh air the risk is very low, because the radon thins quickly. In buildings, on the other hand, the gas often accumulates in the lower rooms, which can lead to alarming concentrations.
Do smokers have an increased risk?
Smokers generally have an increased risk of lung cancer. About 90% of all lung cancer deaths are due to smoking. Studies also show that smokers are also particularly susceptible to the harmful potential of radon. Most radon-related deaths occur in smokers. The following table shows the relationship between radon concentration and the amount of cigarettes smoked:
Table: Risk of dying of lung cancer up to the age of 75 years
Radon Concentration 0 Bq/m3 | Radon Concentration 800 Bq/m3 | |
| Lifelong non-smoker | 0,4 % | 0,7 % |
| Smokers*) up to 30 years of age | 2,3 % | 3,7 % |
| Smokers*) up to 50 years of age | 4,3 % | 7,2 % |
| Smokers*) up to 75 years of age | 10,4 % | 16,9 % |
*) 15-24 cigarettes daily

RadonEye FAQ
The Radon Eye can be operated with or without a smartphone, as the most important measured values are shown on the display. This includes, for example, the measured maximum value (peak), the total measurement duration of the current measurement series and a long-term average value.
However, you will get more detailed data when using the smartphone app. Your smartphone or tablet must meet the following system requirements:
- Bluetooth 4.0 or higher
- Android 4.3 or higher
- IOS 8.0 or higher
