At first Radon Gas was not considered dangerous until it induced lung cancer in the uranium miners and from then on researches have been made and the results have been concluded which suggests that it is the 2nd largest cancer-causing agent in all of humanity.
Radon Gas which is till now is well documented and researched element is a naturally occurring decay product of radium 226 and a fifth decay product of uranium 228. Now as we know that Radon Gas is colorless, odorless as well as tasteless so its identification can’t be suggested until series of tests are conducted. As we know that Uranium 228 and Radium 226 are constituents of most soils and rocks so this could be one of the major reasons that they are found in soils underneath the houses as they are their essential part. Radon Half-life is of 3.28 days after this it decays in to its what is called daughter isotopes known as polonium-218 and polonium-214. They are emitted out during the decay period and these when inhaled they damage the airways and then ultimately gets to settle in the lungs and causes lung cancer eventually.
Around 20 years of research is behind Radon Gas i.e. how it is produced? How it effects etc. It is considered as one of the dangerous indoor pollutants that can cause lung cancer and, in some homes, and structures it can reach a level as high as that of uranium mines where workers get infected with lung cancer. It is found in the soils beneath the floor but remember that water, natural gas, building material etc. also helps this to spread further. When in 1989-1990 Radon Readings were measured they lie in the region of around 1.5 picocuries per liter (pCi/L) but now as because of pollution and global warming and somewhat our carelessness these reading may reach about 3 and 3 above picocuries per liter (pCi/L) which needs to get in line although it’s not dangerous for now but can be if it is left like this.
Lung Cancer & How It Is Caused
Radon Gas is not considered dangerous but its isotopes are i.e. when Radon Gas decays it produces daughter isotopes known as progeny. These isotopes stay in the Air and when inhaled they get stuck in the airway and if not their then in the lungs and ultimately damages the airway and causes lung cancer. These electrically charged and chemical active particles i.e. lead, polonium and bismuth having around 4 picocuries per liter (pCi/L) and are inhaled at a level of 600,000 particles per hour. So, check to see for yourself that if radioactive particles are inhaled in such a large quantity then what kind of damage would be done to our lungs.
Mostly the severity of the damage done to lungs depends upon the condition in which the particles are inhaled i.e. in smoke, with dust etc. If the particles don’t get stuck in the airway then ultimately, they would go in the lungs and cause a deeper (last-stage) lung cancer.
