This Guideline provides the clinical diagnostic criteria for beryllium sensitization and chronic beryllium disease (CBD; old term = berylliosis), based on the latest available medical literature and consultation with leading experts in the field. This Guideline does not address exposure prevention, workplace safety, or treatment. In addition, this Guideline is not intended to supplant all adjud...

At the Ninth International Congress on Industrial Medicine Policard (1948) reported the production of granulomata in the lungs of rats and guinea-pigs by dusting with beryllium oxide. Details of the particle size of the dust were not given. Policard claimed that hyperplasia of the mesenchymatous cells of the lung after dusting with beryllium oxide resulted in three types of response (1) histioc...

Comparative growth measurements of the mycobacterial species Mycobacterium phlei and Mycobacterium tuberculosis were carried out with liquid cultures supplemented with oxalatoberyllate ions in the concentration range 0-120 microM Be. For both species, the effect of beryllium on specific growth parameters can be represented by a Be concentration-dependent, exponential expression. Evidence for be...

Total cross sections for Σ− and π− on beryllium, carbon, polyethylene and copper as well as total cross sections for protons on beryllium and carbon have been measured in a broad momentum range around 600GeV/c. These measurements were performed with a transmission technique adapted to the SELEX hyperon-beam experiment at Fermilab. We report on results obtained for hadron-nucleus cross sections ...

A theoretical study of the beryllium bonds in BeR2:C6X6 (R = H, F, Cl and X = H and F) has been carried out by means of MP2/aug'-cc-pVDZ computational methods. In addition, the ternary complexes BeR2:C6X6:Y- (Y = Cl and Br) have been analyzed. Geometric, energetic and electronic aspects of the complexes have been taken into account. All the parameters analyzed provide a clear indication of favo...

OBJECTIVE We evaluated a workplace preventive program's effectiveness, which emphasized skin and respiratory protection, workplace cleanliness, and beryllium migration control in lowering beryllium sensitization. METHODS We compared sensitization prevalence and incidence rates for workers hired before and after the program using available cross sectional and longitudinal surveillance data. ...

Beryllium, tungsten and carbon are planned as wall-cladding materials for the future international tokamak ITER. Be and W will be the dominant components and therefore the formation of binary Be-W alloys under plasma action is one of the most important issues in plasma-wall interaction processes at the first wall. This paper proposes a first-principles density functional theory (DFT) study of b...

The potential hazards from exposure to beryllium or beryllium compounds in the workplace were first reported in the 1930s. The tritiated thymidine beryllium lymphocyte proliferation test (BeLPT) is an in vitro blood test that is widely used to screen beryllium exposed workers in the nuclear industry for sensitivity to beryllium. The clinical significance of the BeLPT was described and a standar...
