Odorless and colorless, Radon is a natural radioactive gas present in the subsoil that is generated mainly in rocks such as lava, tuff, pozzolane and in granites and sedimentary rocks such as marble and marl. These are the data that we have known for years.
What instead is not disclosed as it should concern both the ease with which this gas can enter our homes and the negative consequences that this could have on our health.
The Radon in fact – extremely volatile – can infiltrate the dwellings placed on the lower floors through both the connection joints between floor to ceiling and walls and through the micro-cracks of walls and foundations.
Furthermore, the pressure difference between the outside and the inside causes a convective movement of the air which facilitates the transport of Radon into domestic environments.
What are the risks to health? The prolonged exposure to the so-called Alpha radiation emitted by the gas damage the mucous membranes of the respiratory system: so much so that the World Health Organization considers it the second cause of lung cancer after cigarette smoking.

The best defensive strategy is to disperse the gas, moving it away, through a ventilated channel structure (called in fact ventilated vespaio) placed under the paving that acts as a mandatory escape route for the gas, thus preventing it from infiltrating the house: an intervention not always easy to build in existing buildings, if not under renovation of the house.

The good news is that the companies specializing in anti-Radon solutions today allow you to create a ventilated crawl space without having to demolish the existing floor: thanks to special and very small lose molds of only 3 cm (plastic micro-modules with the part lower cava) the crawl space can be created quickly and easily, directly on the parquet or on the ceramic.
On the other hand, if the volumes of the living rooms do not allow this solution, it is necessary to intervene in the restructuring phase, first removing the old flooring and the relative screed and, subsequently, creating the new crawl spaces, insulated slab, and cladding.

What is the gas detector?
The gas detector for domestic use is an electronic device used to detect and signal, by means of acoustic and luminous signals, the possible presence, inside the dwelling, of gases harmful to health; then falls into the category of devices for home security. This particular device has been on the market for some time, but in our country, it is not particularly exploited.
Normally, every gas detector is specific for a given gas (single-gas detector) such as, for example, LPG, methane and carbon monoxide); the more sophisticated detectors, besides being able to signal different types of gas (multigas detectors), can be connected to special solenoid valves in order to autonomously interrupt the harmful emissions; the simplest ones, on the other hand, are limited to reporting the loss.

Gas detectors can be of two types: fixed and portable; fixed gas detectors can be for internal use or for external use; in the first case they are installed inside houses or workplaces, while in the second case they are placed externally (it is, for example, the case of carbon dioxide detectors that are used by various municipalities to monitor the levels of this gas in the atmosphere) .
Portable gas detectors, generally battery-powered, are instead devices generally used in the professional field, even if there are portable models for domestic use; they have the advantage of not requiring particular maintenance operations, they are extremely easy to handle and light, but their duration is limited in time.

Gas detector for domestic use: the main types
There are various types of gas detector; the most used are carbon monoxide detectors, LPG detectors, and methane gas detectors.
Detectors of carbon monoxide (CO) or carbon dioxide, if you prefer, are intended to signal the successful escape of carbon monoxide before the symptoms of intoxication are present (carbon monoxide is a colorless gas, tasteless, odorless and has no irritating effects, it can, therefore, cause serious intoxication or even death without the victim being aware of what is happening to her).
Normally carbon monoxide is expelled with other combustion products, but in some circumstances, usually due to maintenance problems or negligence of various types, the monoxide is not expelled and begins to saturate the environment.

How does the gas detector work?
Once a gas concentration higher than the preset limits has been detected, the detector-detector-gas detector will emit an acoustic signal (a prolonged and very intense BIP), a light signal and in some cases an electrical impulse which will distance of the gas supply valve.
Without the detector, a possible gas leak would not be perceived and the flow of gas would not be cut, even when the environment is saturated the oxygen can be consumed giving rise to CO2 and carbon monoxide, which are lethal.

Where to install the gas detector?
It is advisable to place it at home in confined spaces where the gas clouds would be more concentrated in case of escape. The ideal position is to position it about 20 cm from the ceiling in case of methane gas (which is light going upwards) and 20 cm from the floor in the case of LPG (which is heavier than air).

The environments where it is recommended to install it are the kitchen, the boiler room and near the gas taps.
If you are an expert electrician you can install it yourself, otherwise, it is advisable to entrust the work to a specialized technician.
