M Sommer et al.
Radiation protection dosimetry, 119(1-4), 394-397 (2006-06-01)
The optical sensitivity of BeO-based luminophors has been well-known for many years. The optical stimulation of BeO with blue light is most effective. Then the dosemeters emit luminescent light in the ultraviolet-range around 325 nm. Matched on these facts a

Particle dissolution within macrophage phagolysosomes is hypothesized to be an important source of dissolved beryllium for input to the cell-mediated immune reaction associated with development of beryllium sensitization and chronic beryllium disease (CBD). To better understand the dissolution of beryllium
David C Deubner et al.
Journal of occupational and environmental medicine, 53(10), 1187-1193 (2011-09-20)
Beryllium mine and ore extraction mill workers have low rates of beryllium sensitization and chronic beryllium disease relative to the level of beryllium exposure. The objective was to relate these rates to the solubility and composition of the mine and

The absorbed dose is an important parameter in experiments involving irradiation of cells in vitro with unsealed radionuclides. Typically, this is estimated with a model calculation, although the results thus obtained cannot be verified. Generally used real-time measurement methods are
Henrik Grobe et al.
European radiology, 19(5), 1156-1160 (2008-12-17)
The aim of this study was to assess the effect of eye and testicle shielding on radiation dose to the lens and the testes of patients undergoing CT examinations. Fifty-one male patients underwent CT twice with identical protocols initially without
