Beryllium is valued for its strength, formability, thermal and
electrical conductivity, magnetic transparency, and corrosion
resistance. Its low neutron absorption, high neutron scattering
characteristics, and ability to multiply neutrons has led to its use
in experimental nuclear reactors and accelerators. The alloying
property of beryllium confers improved resistance to corrosion,
vibration, shock, and improves alloy hardness and ductility.
The inhalation of beryllium dust or particles can cause chronic
beryllium disease (CBD) and beryllium sensitization. The Department
of Energy has established regulation (10 CFR Part 850) that requires
a chronic beryllium disease prevention program (CBDPP) for certain
work conditions. The goal of the CBDPP is to reduce the number of
workers currently exposed to beryllium, minimize the levels of
exposure to beryllium, and establish medical surveillance
requirements to ensure early detection and treatment of disease.
In 1997 and 1999 BNL conducted reviews of the use of beryllium
on-site. These evaluations determined the applicability of BNL
current operations to DOE regulations and led to the establishment
of BNL policy on the use and handling of beryllium.
