natural radioactivity in building materials radtown us epa

Some building materials, such as granite, brick, marble and other items, contain naturalradioactivity. The amount ofradioactivityin building materials depends on the type of material, but the amount ofradiationreleased from these materials is typically very, very low. Many homes contain decorative rock andstone, such as granite and marble

ionizingradiation hazard recognition occupational

The next two sections on this page provide a starting point for recognizing hazards fromradiation-emitting equipment or devices. OSHA's IonizingRadiationStandard (29 CFR 1910.1096) requires employers to protect workers fromexposureto ionizingradiationsources that are not regulated by other federal agencies (e.g., the U.S. Nuclear Regulatory Commission, NRC), such as X-ray equipment

radioactivecancer drugs could pose risk to cremation

Cancer patients often receiveradioactivedrugs that target tumor cells. A new case report suggests there could be unanticipated fallout if these patients die and their bodies are cremated

9 surprising sources ofradiationin household items

Exposuretoradiationcan be very harmful to you. It’s been fodder for sci-fi movies for decades, turning tiny tots into mutated henchmen (The Gamma People, 1956) and transforming a cowering homemaker into a giantess with a score to settle (Attack of the 50 Ft. Woman, 1958).The real-world risks of chronic high-levelexposureare known to be equally dramatic—and deadly

Worrying for risk ofexposureto theradiation, Nathan Yu, a resident physician in the Mayo Clinic’s department ofradiationoncology and the lead author of the study analyzed the urine of the crematory worker. Here’s where it gets weirder. They found an altogether differentradioactivematerial called technetium-99m

nuclear pollution.ppt \u2022nuclear pollution like any

•Radioactivedecay occurs because unstable isotopes tend to transform into a more stable state.Radioactivityis measured in terms of disintegrations, or decays, per unit time. Common units ofradioactivityare the Becquerel, equal to 1 decay per second, and the Curie, equal to 37 billion decays per second.Radioactivewaste is usually the product of a nuclear process such as nuclear fission

radioactivechemomeds might threaten crematorium workers

A Geiger-Mueller detector detected radiation contamination in the crematory equipment, including the oven, the vacuum filter used to remove ashes, and the bone crusher, Nelson said. A spectroscopic radiation detector showed that the radioactivity was primarily from lutetium 177

radiationhazards from brick home

It is true that brick andstoneare likely to be moreradioactivethan wood, simply because brick andstonecontain more naturallyradioactivematerial like uranium and thorium. Scientific studies (which YouTube videos most definitely are not!) have found that for brick-veneer houses, the building materials contribute about 0.008 microsievert

are irradiated gemstones dangerous gem rock auctions

The longer a gemstone is exposed to irradiation the more chance of the stone becoming radioactive. The reason why gemstones become radioactive is if impurities within the gemstone become active. Stones treated with either electron or neutron irradiation will remain radiaoactive for a period of time
