Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies. Radon is a significant contributor to environmental radioactivity and indoor air pollution. Exposure to radon can cause serious health problems such as lung cancer. [1]
The level of radon in the air of mines is now normally controlled by law. In a working mine, the radon level can be controlled by ventilation, sealing off old workings and controlling the water in the mine. The level in a mine can go up when a mine is abandoned; it can reach a level which can cause the skin to become red (a mild radiation burn).
Radon has been produced commercially for use in radiation therapy, but for the most part has been replaced by radionuclides made in particle accelerators and nuclear reactors. Radon has been used in implantable seeds, made of gold or glass, primarily used to treat cancers, known as brachytherapy. The gold seeds were produced by filling a long ...
Additionally, as car tires wear down, they shed the materials they are made of into the air as particulate pollution. [10] Those pollutants are known to cause various respiratory and other health issues and cars are among the leading cause of smog in modern developed world cities. External costs which can arise from using cars and trucks in ...
Misleading videos and false claims that President Joe Biden wandered off aimlessly from the G7 conference last week continued to go viral despite debunkings and fact-checks that tried to correct ...
Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.
The windshield phenomenon (or windscreen phenomenon) is the observation that fewer dead insects accumulate on the windshields and front bumpers of people's cars since the early 2000s. It has been attributed to a global decrease of insect populations caused by human activity, e.g. use of pesticides. [1]
Alternatively, radon may enter the body through contaminated drinking water or through the decay of ingested radium [3] – making radon diffusion one of the greatest dangers of radium. [10] Thus, 222 Rn is a carcinogen ; in fact, it is the second leading cause of lung cancer in the United States after cigarette smoking , [ 3 ] with over 20,000 ...
