Dangers !

The radon gas is dangerous as we breathe it. During the respiration, it goes inside lung and some atoms give out energetic radioactive particles. This one kill all cells on its way. More it is concentrated, more the number of slayer particles is significant.

Nevertheless, the radioactivity is a natural state of the matter. It arise from all soils or waters and space, it is always around us. Human have always get its radiation since his existence, the radioactivity is well tolerated by our organism. But, this is right lonely if the radioactivity don't exceed the natural rate.

This is the same for radon. However, since several year this gas become dangerous for our health because we live more with it and it more concentrated. Two raisons explain this fact :

• Thermal isolation whom restrict air exchange with outside. By this way the radon gas stays inside home and get an important concentration.
• Mores evolutions, people stay now 80% (mean) of their life time in a closed room. We breathe more dangerous gas than before.

Thus, with this new habits, the radon give more than the half (58%) of the daily natural radioactive dose (35% with all sources). According World Health Organisation (WHO), 6 to 15% of the lung cancer are due to radon.

The other fact is each increasing of 100Bq/m3 (100Bq/m³ is the natural radon rate), grows of 16% the probability to have a lung cancer. Today, 10% of the population live with a rate upper than 300 Bq/m3 and 1% with a rate of 1000Bq/m³.

Yet, the danger is not instantaneous, nothing comparable to the carbon monoxide or other dangerous gas. Its natural presence is not dangerous too. But, struggle against its accumulation allows to reduce strongly the probability to have a lung cancer.
