In a word, no. Research in America has indicated that there is likely to be more radon in the building materials found in the average home than in a granite worktop.
Radon gas is a by-product of the radioactive decay of radium which comes from uranium. It is not possible to see, hear, smell or taste radon gas which occurs naturally through the presence of uranium in most rocks, soils, bricks and concrete. The main source of radon is the soil or rock beneath a dwelling and areas where there are likely to be high levels of radon emission are well documented and can be found on radon maps.
Radon gas itself does not present too serious a radiological hazard when breathed in and immediately exhaled. The problem lies with the decay products which behave like solids and can attach themselves to dust and moisture in the atmosphere. These solids can take up residence in lungs and airways and emit alpha particles which are known to cause cell damage. We all breathe in radon to some extent and it accounts for half of the radiation dosage each of us receives. |
