Türkisch - Englisch
(Nükleer Bilimler) beryllium
A hard brittle, gray-white metal Resistant to oxidation at ordinary temperatures Used in computer parts, x-ray tubes, gyroscopes and rocket fuel additive Hazard: Highly toxic, especially by inhalation of dust Long term exposure may cause weight loss, weakness, cough, extreme difficulty in breathing and cardiac failure
It does not occur uncombined in nature but is found chiefly as the mineral beryl (of which emerald and aquamarine are gemstone varieties). Beryllium metal, particularly in alloys, has many structural and thermal applications; it is used in nuclear reactors. Beryllium has valence 2 in all its compounds, which are generally colourless and taste distinctly sweet. All soluble beryllium compounds are toxic. Beryllium oxide is used in specialized ceramics for nuclear devices, and beryllium chloride is a catalyst for organic reactions
The chemical element with an atomic number of 4; a light metal with specialist industrial applications
Chemical element, lightest of the alkaline earth metals, chemical symbol Be, atomic number
{i} (Be) lightweight metallic chemical element commonly used in alloys
An airborne metal hazardous to human health when inhaled It is discharged by machine shops, ceramic and propellant plants, and foundries
a light strong brittle gray toxic bivalent metallic element
A highly toxic steel-gray metal, possessing a low neutron absorption cross-section and high melting point, which can be used in nuclear reacotrs as a moderator, reflector, or cladding material In nuclear weapons, beryllium surrounds the fissile material and reflects neutrons back into the nuclear reaction, considerably reducing the amount of fissile material required Beryllium is also used in guidance systems and other parts for aircraft, missiles or space vehicles
Occurs naturally in soils, groundwater and surface waters and is often used in electrical equipment and electrical components It generally enters water from runoff from mining operations, discharge from processing plants, and improper waste disposal Measured in mg/L or ppm The MCL for beryllium is 0 004 mg/L or ppm
A grayish-white, brittle, toxic, metallic substance with an atomic weight of 9 01 It is one of the lightest of all metals, resists oxidation in air and is nonmagnetic
A greyish-white metal occurring naturally in certain rocks, soils and volcanic dust A major emission source to the environment is through the fly ash from combustion of coal and fuel oil, which can contain the metal It is used in nuclear reactors, radio and television tubes, fluorescent tubes and powders It is discharged by machine shops, ceramic and propellant plants, and foundries In the environment, it ultimately accumulates in sediments Beryllium can cause severe dermatitis problems and can be toxic if inhaled It is a Group B2, animal carcinogen
A metallic element found in the beryl
An metal hazardous to human health when inhaled as an airborne pollutant It is discharged by machine shops, ceramic and propellant plants, and foundries
An alkaline earth metal used in X-ray tube windows, watch springs and sparkless tools
