Soon after the war ended, however, a secret report circulating within the newly created Atomic Energy Commission (AEC) noted that the federal government was "acutely interested in maintaining and expanding production of beryllium." (15) The report cautioned that if the incidence of berylliosis in workers became known outside the defense establishment, the outbreak "might be headlined, particularly in non-friendly papers, for weeks and months," and this might in turn "seriously embarrass the AEC and reduce public confidence in the organization." (16) Rather than risk that embarrassment and a potential reduction in beryllium supplies, the AEC and its contractors decided to keep the incidence of berylliosis under wraps.
