Dec 01, 2019 The number of workers exposed to beryllium has been estimated at 1 million in the US, although no accurate figure exists for the US or globally. The prevalence of BeS in those exposed ranges from 1 - 20%. Chronic beryllium disease
Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays.Within the cores of stars, beryllium is depleted as it is fused into heavier elements. It is a divalent element which occurs naturally only in combination with
Beryllium is a metal that is used in small amounts in many industries. Beryllium exposure is a common but underrecognized cause of illness in people who mine and process beryllium and in many industries, including beryllium alloy production, metal alloy machining, electronics, telecommunications, nuclear weapon manufacture, defense, aircraft, automotive, aerospace,
Beryllium, chemical element that is the lightest member of the alkaline-earth metals of Group 2 of the periodic table. It is used in metallurgy as a hardening agent and in many outer space and nuclear applications. It is a steel-gray metal that is quite brittle at room temperature.
In making a diagnosis of chronic beryllium disease, your doctor will start by taking a detailed medical and occupational history and conducting a thorough medical examination. This will help determine if you have been exposed to any toxic substances that may have caused CBD or other occupational lung diseases.
Beryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table. The metal is unaffected by air or water, even at red heat. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity.
Beryllium is lightweight and recyclable, important to the environmental impact of any of its end-use applications. You’ll also find it at the center of exciting developments in alternative energy. Helping the Economy. The United States is the leading producer of beryllium and a major exporter of the material. Beyond the favorable economic ...
May 18, 2018 Beryllium is a fairly rare element on our planet. It is characterized by a number of valuable properties: when it reaches certain conditions it serves as a source of neutrons, besides it is very light, about 4 times lighter than iron.
Berylliosis, or chronic beryllium disease (CBD), is a chronic allergic-type lung response and chronic lung disease caused by exposure to beryllium and its compounds, a form of beryllium poisoning.It is distinct from acute beryllium poisoning, which became rare following occupational exposure limits established around 1950. Berylliosis is an occupational lung disease.
