Beryllium Toxicity: Who Is Susceptible to Beryllium
Individual susceptibility to sensitization and exposure circumstances are both important in developing chronic beryllium disease (CBD) (Kreiss et al 1993) In CBD, a susceptible person develops a cellmediated, delayed hypersensitivity reaction after beryllium exposure (Tinkle et 09/12/2021 Beryllium Disease Among Construction Trade Workers at Department of Energy Nuclear Sites American Journal of Industrial Medicine; Designing a Beryllium Exposure and DiseaseManagement Program for Workers in the Air Force National Academy of Sciences; Development and Evaluation of a Screening Test for Beryllium Sensitization DOE, ORAU, Beryllium Safety IH/OS SIGSUMMARY AND EVALUATION 21 Human Exposure The increasing hightechnology application of beryllium is paralleled by an increase in potential human exposure to beryllium metal, beryllium oxide, and berylliumcontaining alloys However, providing that control measures in the beryllium industry are adequate, the general population is mainly exposed to airborne Beryllium (HSG 44, 1990) International Programme on
