We are all exposed daily to small amounts of radiation from natural sources of radioactive material. Much of this natural radiation comes from radioactive materials in building materials and in soil in the environment.
What building materials contain radioactive material?
Some building materials contain low levels of radioactive material. Building materials that are made up of sandstone, concrete, brick, natural stone, gypsum, or granite are most likely to emit low levels of radiation.
Radioactive materials in sandstone, concrete, brick, natural stone, gypsum, and granite contain naturally-occurring radioactive elements like radium, uranium, and thorium. These naturally-occurring elements can break down or decay into the radioactive gas radon. Depending on the amount of these materials present, they may also cause small increases in radiation levels. Amounts (doses) of radiation in building materials depend on the type and amounts of materials used.
How much radiation exposure can I get from building materials?
Building materials that are made up of sandstone, concrete, brick, natural stone, gypsum, and granite are highly unlikely to contain radioactive material that will increase radiation dose above the low levels of background radiation we receive on a daily basis.
Radioactive material in building materials may add to indoor radon levels. However, radon is more likely to get into your home through cracks and holes in your foundation (underneath the home) or private well water (groundwater). Elevated indoor radon levels may pose a risk to human health.
You can test your building to make sure there are safe levels of radon.
What is the risk from radiation found in building materials?
For the most part, the levels of radioactive materials found in building materials are very low. These low levels of radioactive material, and the radiation emitted by them, are unlikely to harm human health.
Building materials, such as brick, marble and granite, contain very low-levels of naturally-occurring radioactivity
naturally-occurring radioactivity
Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) is defined as, "Naturally occurring radioactive materials that have been concentrated or exposed to the accessible environment as a result of human activities such as manufacturing, mineral extraction, or water processing.”
. However, these materials can emit radon as the materials decay, which can elevate the indoor radon levels in your home. It's important to test your home for radon and to correct elevated levels.
Radioactive materials in sandstone, concrete, brick, natural stone, gypsum, and granite contain naturally-occurring radioactive elements like radium, uranium, and thorium. These naturally-occurring elements can break down or decay into the radioactive gas radon.
Construction workers can be exposed to ionizing radiation from both natural and manmade souces. Radon — Rock and soil rich in uranium decays to radon gas which produces alpha particles. Alpha particles can be inhaled with air and deposited in the lungs, thereby increasing the risk of lung cancer.
Common building products such as brick, cement, granite, and glazed tiles may contain radioactive materials. Nearly all rocks, stone, soils, and minerals contain trace concentrations of naturally occurring radioactive materials such as radium, thorium, and uranium.
Brazil nuts. Brazil nuts (especially the ones grown in Brazil) grow on trees with deep roots, which reach down to soil high in natural radium, a source of radiation. ...
Abstract. Optical Radiation is a relevant occupational risk in construction workers, mainly as a consequence of the exposure to the ultraviolet (UV) component of solar radiation (SR).
People who receive a high radiation dose also can have skin damage. This damage can start to show within a few hours after exposure or it may be delayed for several days. It can include swelling, itching, and redness of the skin (like a bad sunburn) or may be more severe and include blisters or ulcers.
The top four causes of construction fatalities are: Falls, Struck-By, Caught-In/Between and Electrocutions. Wear and use personal fall arrest equipment. Install and maintain perimeter protection. Cover and secure floor openings and label floor opening covers.
Common sources of radiation include medical tests (mammograms, X-rays, CT scans), airport security screening, building materials, cigarette smoking, cell phones, wearable technology, sunlight, tanning beds, and more. Materials that can block radiation, include lead, concrete, and water.
This type of dye binds to particles of radioactive elements known as cesium and thallium. The radioactive particles then pass out of the body in feces. This treatment speeds up the elimination of the radioactive particles and reduces the amount of radiation cells may absorb.
Experts suggest testing all homes below the third floor. You can get a radon test kit through the mail or at a hardware store. Or you can hire a radon professional. The test will measure radioactivity in the air.
The walls of a building can block much of the harmful radiation. Because radioactive materials become weaker over time, staying inside for at least 24 hours can protect you and your family until it is safe to leave the area.
All metals, in fact all elements and materials in general absorb radiation (photons). The absorption is almost entirely due to photons interacting with the electrons.
Radon released from granite building materials can be released over the lifetime of use but typically will be diluted by ventilation. In addition to radon, naturally occurring radioactive elements in the granite can emit small amounts of beta and gamma radiation.
