Hearing the word itself makes us annoyed and worried. Radiation is indeed a very scary word that marks tremendous negative effects throughout the history of mankind. From the disaster of nuclear bomb planted on Hiroshima and Nagasaki, then the Chernobyl nuclear disaster and to the latest nuclear plant disaster at Fukushima, Japan. Radiation can be extremely dangerous, especially in large doses. Though dramatic events like nuclear meltdowns and the possibility of nuclear war are the risks we most readily connect with radiation, it is the constant everyday lower level of radiation that we should be most concern about.
Radiation is in fact, a regular part of the life. From the day we were born to the day we die, our bodies are subjected to expose to persistent barrage of the energize atomic particles of radiation. The sources of everyday radiation are far more common than people are aware – being out in the sun (sunlight contains ultraviolet radiation), getting a dental x-ray (x-rays are forms of radiation), flying in an airplane (at higher altitude, you have less of the earth’s atmosphere to protect you from cosmic radiation- including from the sun), or even spending time in concrete building (concrete contains small amounts of uranium that emit radioactive radon gas) – Radon is the leading source of natural radiation exposure and the second leading cause of lung cancer. Where does it come from? Well, usually from soil, but it is found everywhere. The ground that we all walk and build our homes upon contains varying levels of naturally occurring radioactive elements that decay into radon gas, which can seep into homes and become a health concern.
