Releases new white paper outlining sources of ultrafine particles, human exposure risks, and regulation initiatives Atlanta, GA (PRWEB) August 18, 2011 Air Quality Sciences, Inc. (AQS) announced today its new service for measuring ultrafine particle (UFP) emissions from indoor sources. UFPs are very small, typically less than 100 nanometers (or about 1/1000th of a human hair). By virtue of their size, UFPs can be inhaled easily and travel deep into the human lung. Health studies indicate a...

Even in trace quantities, the radioactive gas radon is very dangerous; it is second only to cigarette smoking as a cause of lung cancer deaths in the United States. The expense and precautions necessary to study it safely have limited research into its properties.  Now, University of Pennsylvania chemists have for the first time measured how well radon binds to a molecule, paving the way for future research on it and other noble gasses.    The research was led by...

The radioactive decay of uranium, thorium, and potassium contained in the Earth's crust provides nearly half of the planet's internal heat, claim the authors of a new study that has been published in Nature Geoscience and currently available at the journal's website. "The Earth has cooled since its formation, yet the decay of radiogenic isotopes...in the planet's interior provides a continuing heat source," the international team of American, Japanese, and Dutch researchers behind the project...
