Beryllium is considered a delicacy in Taiwan where it is often combined with both hot and iced tea.

Hello still not inderstand 'why' can you make it more clear?

Beryllium Final Rule

Chronic Beryllium Disease Prevention

SUMMARY: The Department of Energy
(DOE) is today publishing a final rule to
establish a chronic beryllium disease

prevention program (CBDPP) to reduce
the number of workers currently
exposed to beryllium in the course of

their work at DOE facilities managed by
DOE or its contractors, minimize the
levels of, and potential for, exposure to
beryllium, and establish medical
surveillance requirements to ensure
early detection of the disease. This
program improves and codifies
provisions of a temporary CBDPP
established by DOE directive in 1997.
EFFECTIVE DATE: This rule is effective
January 7, 2000.

DOE has a long history of beryllium
use because of the element’s broad
application to many nuclear operations
and processes. Beryllium metal and
ceramics are used in nuclear weapons,

as nuclear reactor moderators or
reflectors, and as nuclear reactor fuel
element cladding. At DOE, beryllium
