In a recent study, researchers at the University of Utah conducted the first rigorous analysis to date a landslide that had occurred thousands of years ago in what is now Zion National Park in Utah.
Scientists have known for some time that the flat floor of this park was previously a lake originally created when a massive rock avalanche dammed up the Virgin River, but it was still unclear exactly when this landslide occurred.
Beryllium has long been a topic of interest to researchers who have examined its harmful effects on health in people who are exposed to the metal on a daily basis for long periods of time.
However, this risk does not apply to people in the general population who do not actually handle beryllium, Pepper said."Beryllium becomes harmful when it is generated into an airborne particulate …
There is currently no cure for the disease, whose progression can be slowed by medication, oxygen therapy, and lung transplants in severe cases, according to the University of California San Francisco Medical Center.
Interestingly, not all those who get exposed to potentially harmful levels of beryllium will experience an allergic, potentially deadly reaction.
The creation occurs within minerals the upper meter of rocks exposed directly to the sky.Their work was published in 2016 in GSA Today, the journal of the Geological Society of America.Beryllium dating is used to estimate the time a rock has been exposed on the surface of the Earth, as well as erosion and sedimentation rates. Like carbon-14, most of it is formed in the earth’s upper atmosphere.Beryl and bertrandite are the most important commercial sources of the element and its compounds.
Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry.
"There is a genetic susceptibility component, which means that not everyone who is exposed is at risk of going on to develop sensitization, then chronic beryllium disease," Pepper said.
