National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Beryllium Sampling Methods. (Comparison of Two Personal Sample Collection Methods with the AEC Sample Collection Method as Used for One Year in a Beryllium Production Facility).

PB266581

Publication Date	1976
Personal Author	Donaldson, H. M.; Stringer, W. T.
Page Count	32
Abstract	Three sampling methods for airborne beryllium are compared to validate observations made in a 1973 NIOSH industry wide study of the beryllium industry which found that, in general, the three methods yielded differing results for samples taken in the same environment. A NIOSH contractor sampled its beryllium production facility by the Atomic Energy Commission, personal total, and personal respirable sampling methods over a period of one year. All samples were analyzed by atomic absorption spectroscopy. Statistical analysis of the resulting data by NIOSH confirms the conclusions made in the 1973 study. No reliable conversion was found to exist between results obtained from the three methods on a single sample basis. However, it appears that for large numbers of samples taken under the same sampling conditions that when the concentration is 2 micrograms beryllium per cubic meter as determined by the AEC sampling method, that the value as determined by the personal respirable sampling method will be approximately 1 micrograms beryllium per cubic meter and the value as determined by the personal total sampling method will be approximately 3 micrograms beryllium per cubic meter.
