Beryllium and beryllium compounds were considered by previous IARC Working Groups in 1971, 1979, 1987, and 1993 (IARC, 1972, 1980, 1987, 1993). Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consideration in the present evaluation.

Beryllium. The moderating takes place by the collisions between the neutrons and the nuclei of moderator material. The most efficient moderating materials are those of low atomic mass, as close as possible to the mass of the neutron; such materials include water, heavy water, graphite, and beryllium.

A FIELD INSTRUMENT FOR QUANTITATIVE DETERMINATION OF BERYLLIUM BY ACTIVATION ANALYSIS By W. W. Vaughn, E. E. WUson, and J. M. Ohm ABSTRACT A lowcost instrument has been developed for quan­ titative determinations of beryllium in the field by by activation analysis. The instrument makes use of

Beryllium Part 1. I am including here the script for the section on sources of beryllium: Sources of Beryllium. Beryllium is the first member of the alkaline earth family of elements, which means that it's highly reactive and easily bonds to form compounds but is difficult to separate into a pure metal.

The plant is a mill and finishing facility for beryllium, a highstrength, lightweight metal used in military, aerospace, and medical industries. The ore for the plant comes from Brush Wellman's mine, located in the TopazSpor Mountains, 50 miles west, which is North America's only developed source for the metal.

On October 1, 1987, beryllium and beryllium compounds were placed on the list of chemicals known to the State of California to cause cancer, as required under the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). The International Agency for Research on Cancer (IARC) has classified beryllium and beryllium

Barium, beryllium, calcium, magnesium and strontium belong to a group of chemicals called the "alkaline earth metals." Although these chemicals belong to the same chemical group, they vary widely in their abundance and behavior in ground water and in their potential health effects. What are sources of barium, beryllium, calcium, magnesium and

Beryllium is a naturally occurring element that is extracted from ores and processed into metal, oxides, alloys, and composite materials. Industrial use of beryllium, such as machining metal parts, can lead to BeS and CBD ().The major applications of beryllium are in automotive electronics, telecommunications, computers, aerospace, and defense equipment ().
