These days, beryllium is typically obtained from the minerals beryl and bertrandite in a chemical process or through the electrolysis of a mixture of molten beryllium chloride and sodium chloride, the Jefferson Lab reports.

Beryllium is found in about 30 mineral species, including bertrandite, beryl, chrysoberyl, and phenacite, according to the Los Alamos National Laboratory. 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. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites.
Thanks to its low thermal neutron absorption cross-section, beryllium is used in nuclear reactors as a reflector or moderator. Moreover, the high melting point of beryllium oxide makes it a useful material for nuclear work and ceramic applications, according to the Los Alamos National Laboratory. 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.
This immunologic response, called beryllium sensitization, can then develop into chronic beryllium disease, which causes scarring of the lung tissue and can be deadly. 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.

About 85 percent of people who develop chronic beryllium disease after getting exposed have an immune system protein known as HLA-DP2, according to recent research published in July in the journal Cell. In the study , researchers determined that the bodies of people who have this protein create a unique molecular "pocket," which captures beryllium ions and triggers an inflammatory response in the lungs. He added that the new findings could one day lead to new therapeutic strategies to treat and prevent chronic beryllium disease.
Using a technique known as cosmogenic nuclide dating, scientists can determine how long rocks have been exposed to the air by measuring their levels of beryllium, a radioactive isotope of beryllium.
Cosmogenic nuclide - Wikipedia
Cosmogenic nuclide dating is often used to determine the dates of important geological events, such as glacier advances and retreats, rock slides, meteor impacts and lava flows. For example, after a rock avalanche, boulders that land on top of the heap have surfaces that are exposed to the sky for the first time. Particles from incoming cosmic rays high-energy radiation from outer space begin to hit these boulder surfaces, creating beryllium When went items, views of the rocky mountains of sand in atlantic with appreciable loss of quality in taking lessons to learn how to act responsibly.
