For that reason, the term “radon” identifies mainly the 222 Rn and this is the convention followed thereafter. Radon ( 222 Rn) is released primarily from soil and approximately 10% of it is released into the atmosphere ( 3, 4 ). 218 Po, 214 Pb, and 214 Bi are radon’s most significant progeny in terms of radiation dose.Everyone is exposed to radon in the air. People can be exposed to radon through a variety of sources: Radon comes from soil, water, natural gas, and building materials. Human exposure to radon occurs through inhalation and ingestion. Nearly 1 out of every 15 homes in the United States is estimated to have elevated radon levels.Endocrine disruptors are found in many everyday products, including some cosmetics, food and beverage packaging, toys, carpet, and pesticides. Some chemicals that act as flame retardants may also be endocrine disruptors. Contact with these chemicals may occur through air, diet, skin, and water.

Radon gas is inert, colorless and odorless. Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation.Background radiation varies from place to place and over time, depending on the amount of naturally-occurring radioactive elements in soil, water and air. Weather conditions also affect radiation levels, as snow cover may shield these elements, and radioactive particulates can wash out of the air during rain storms.Since the 1960s, studies on underground miners have consistently demonstrated an increased risk of lung cancer caused by radon and its progeny (15). Based on this evidence, IARC classified radon as a human carcinogen in 1988 (46). Since then, several reviews on radon-related risk among miners have been published (1,4,21,28). 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 ...

Last updated on November 10, 2022 There are no immediate symptoms from exposures to radon. Based on an updated Assessment of Risk for Radon in Homes, radon in indoor air is estimated to cause about 21,000 lung cancer deaths each year in the United States. Smokers are at higher risk of deveAny home can have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. The EPA estimates that 1 out of every 15 homes in the United States have elevated radon levels above 4 pCi/L. Radon mitigation systems are highly effective in reducing radon concentrations to below 4 pCi/L. In New ….

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Health effects from indoor air pollutants may be experienced soon ...Soil has a considerable effect on human health, whether those effects are positive or negative, direct or indirect. Soil is an important source of nutrients in our food supply and medicines such as antibiotics. However, nutrient imbalances and the presence of human pathogens in the soil biological community can cause negative effects on health.
