HOW TO RECEIVE THE EQUIVALENT RADIATION DOSE OF 90 CHEST X-RAYS PER YEAR... WITHOUT LEAVING YOUR HOUSE

摘要

Would you be prepared for each member of your family to undergo 90 chest x-rays per year? Probably not. In any case, it is unlikely that a medical professional would permit this, due to the potentially harmful radiation dose that your body would receive. Many Britons are, however, being exposed to the equivalent level of radiation just by spending time in their homes and workplaces. Radon is the naturally-occurring radioactive gas that is formed during the decay of uranium in the ground. When the gas permeates into open air, it is quickly diluted to low concentrations, where it poses no threat to human health. If the gas permeates into a building, however, it becomes trapped and can build to dangerously high levels.
