Description

Canary Digital Radon Monitor - Leasing (just Germany and Austria)

Canary gives you the possibility to read the average value for 1 day, for 7 days, and accumulative for the last year. Being battery powered, the monitor can easily be moved around the building, in order to get the full overview of the radon in the home, the workplace, the school or in the kindergarten. Compared to traditional technology, Canary makes it much easier to locate the radon entry in the buildings. If the radon level is above the national action level, you can easily read the effect of simple mitigation measures, before you may have to consider more comprehensive mitigation actions by professionals.

FAQ (4)

Radon in general

General questions with answers about radon

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:

Questions and answers about Airthings Corentium Home.

The Corentium Home Radon Meter from Airthings displays the average radon concentrations of the last 24 hours, the last 7 days, and a long-term value (since the last RESET). It can therefore NOT provide hourly values, but only cumulative average values.

Daily average value / 1 Day:

The instrument displays the average Radon value of the last 24 hours. That means, if you look at the instrument on 19.02.2018 at 15 o'clock, the value shows you the average Radon concentration per hour in the period 18.02.2018 from 15 o'clock until the present time, i.e. 19.02.2018 at 15 o'clock.

Weekly average value / 7 Day:

Again, the Corentium Home device shows you the average radon concentration per hour for the last 7 days. This means that on a Monday, the device would show you the average concentration from last Monday to this day.

LongTerm value:

The device shows you the average radon concentration per hour since the last RESET.
