SANTIAGO DE COMPOSTEU (USC) GALIZA RADÓN LABORATORY INVESTIGATORS CONFIRMED THE RELATIONSHIP BETWEEN ESOPHAGE CANCER AND HIGH RADON GAS CONCENTRATION LEVELS
The study published in the International Journal of Radiation Biology , has demonstrated a direct relationship between residential gas accumulation and mortality from this disease , ie the municipalities of Galicia with higher concentration of radon in homes also have a higher rate of mortality from esophageal cancer among men.
To conduct this study, researchers measured the concentration of this gas in more than 3,500 Galician homes and workplaces and found that municipalities with a higher concentration of residential radon also had higher mortality from esophageal cancer among non-smoking men.
Professor Alberto Ruano de la USC led this research in which experts from the “National Center for Epidemiology of the Carlos III Health Institute” also participated.
This same team recently published the results of another study that concluded that there is a strong association between residential radon and lung cancer , and is currently working on research that focuses on individuals who have never smoked and which also relates residential radon with a higher risk of lung cancer.
Also the “Radon Laboratory of Galicia” has just obtained the necessary funding to deepen the biological process by which radon produces this cancer. Directed by Professor Miguel Barros, the research will analyze over the next three years 1,400 individuals.
ACCUMULATES IN CLOSED ENVIRONMENTS
Radon gas is a human carcinogen recognized by the World Health Organization (WHO) that accumulates naturally inside homes and other indoor environments. In fact, home radon is the leading cause of lung cancer in non-smokers and the second risk factor of this disease in smokers.
