Exposure to high levels of radon through breathing air is known to cause lung diseases. When long-term exposure occurs radon increases the chances of developing lung cancer. Radon can only cause cancer after several years of exposure. Radon may be radioactive, but it gives off little actual gamma radiation.
Smoking contributes to the vast majority of lung cancer cases in Manitoba and poses a much greater risk than exposure to radon gas. Each year, over 600
isotope of radon, radon-222 has a physical half-life of 3.823 days that comes from the decay of radium. or on has a phys - ical half-life of 55.6 seconds that comes from decay of thori - Radon-222 is a radioisotope of radon. Radon is a colorless, odorless, tasteless noble gas, occurring naturally as the decay product of radium.All isotopes of radon are radioactive, but the two radon isotopes radon-222 and radon-220 are very important from radiation protection point of view. You won’t have symptoms of radon poisoning right away. Instead, health problems from the exposure, such as lung cancer, show up after many years. Lung cancer may start as a nagging cough, shortness The National Academy of Sciences (NAS) on Thursday, February 19, 1998, announced the findings of its Biological Effects of Ionizing Radiation (BEIR) VI Report: "The Health Effects of Exposure to Indoor Radon." This report by the NAS is the most definitive accumulation of scientific data on indoor radon. The report confirms that radon is the second leading cause of lung cancer in the United States and that it is a serious public health problem.
The United Nations Scientific Committee on the Effects of Atomic Rad 14 Aug 2019 In Canada, radon kills at least 3000 people annually, making it the second leading cause of lung cancer [2]. This naturally-emitted soil gas enters Why is radon a concern? Radon is a Lung Cancer Causing Gas; What happens when radon decay products are inhaled? Probability Radon-222 (radon) is a radioactive gas with a half-life of 3.8 days that is released radon gas released by well water The Numbers and Public Health Impact. readily adsorbed onto atmospheric particles, posing a significant health hazard. Inhalation of 222Rn, and its -emitting progeny 218Po and 214Po, is believed [8] What are the health effects of radon?
radon-222 (222Rn), den vi kallar för radon och som har en halveringstid på 3.82 dagar. Till radonisotoperna hör även radon-220 (220Rn), kallad toron, och radon-219 (219Rn), kallad aktinon, vilka även dessa förekommer naturligt (Rosario & Wichmann, 2006).
Some investigators, not allowing for the effects of radon daughters, argued that the lung doses due to radon exposures were insufficient to account for the observed responses (Lorenz, 1944). When the effects of the daughters were considered, however, it was clear that the lung doses were well above levels thought to be safe.

Radon as a noble gas is A discussion is given of the health effects of radon-222 and its short-lived daughters which arise from tailings in milling operations. It is shown that the radioactive decay product of thorium-230, radon-222, together with short-lived species polonium-218 and -214 Radon-222 is especially dangerous because its longer half-life allows it to permeate soil and rocks, where it is produced in trace quantities from decays of uranium-238, and concentrate in buildings and uranium mines. exposures and health effects. These studies have established beyond any reasonable doubt that radiation is a causative agent of cancer in many organs and tissues of the You won’t have symptoms of radon poisoning right away. Instead, health problems from the exposure, such as lung cancer, show up after many years.
It is estimated that radon causes between 3% to 14% of all lung cancers in a country, depending on the national average radon level and the smoking prevalence.

Health effects content gone. Seems I missed a bad edit in an earlier revert. Marked for split-off anyway, I'm not going to re-include the section, but please also consider this content on the health effects of environmental radon. Femto 13:34, 24 February 2006 (UTC) Health Benefits Of Radon. There does seem to be something to it, actually.
Radon primarily enters buildings through the soil The radioactive gas radon is a hazard in many homes and workplaces. Breathing in radon is the second largest cause of lung cancer in the UK resulting in over 9 Mar 2021 You can read about basic radon facts, health effects, sources of radium-226 and radon-222 are present in almost all rock and all soil types. Exposure to high concentrations of radon gas is the leading cause of lung cancer for urban sprawl and lack of public awareness about the radon gas health issue.

For smokers the risk of lung cancer is significant due to the synergistic effects of radon and smoking. Health effects of radon Radon is a major cause of lung cancer. It is estimated that radon causes between 3% to 14% of all lung cancers in a country, depending on the national average radon level and the smoking prevalence. An increased rate of lung cancer was first seen in uranium miners exposed to very high concentrations of radon.
Overall, radon is the second leading cause of lung cancer. Radiation exposure from radon is indirect. The health hazard from radon does not come primarily from radon itself, but rather from the radioactive products formed in the decay of radon. The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary The average annual radiation dose to a person from radon is about 2 mSv/year and it may vary over many orders of magnitude from place to place. According to a 2003 report EPA’s Assessment of Risks from Radon in Homes, epidemiological evidence shows a clear link between lung cancer and high concentrations of radon.
