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.

Radiological Characterization and Assessment Study of a Coal Slag Used for Abrasive Blasting.

PB96191895

Publication Date	1995
Personal Author	Cox, C.; Telofski, J. S.; Goode, P. R.
Page Count	58
Abstract	An unopened bag of coal slag used for abrasive blasting was submitted by the National Institute for Occupational Safety and Health (NIOSH) to the National Air and Radiation Environmental Laboratory (NAREL) for radiological characterization by gamma and alpha spectrometry analysis. Major radionuclides detected by gamma and alpha spectrometry were those in the naturally occurring U-238, U-235, and Th-232 decay series and K-40. Results of the gamma spectrometry analysis indicated a total activity of about 195 picoCuries per gram (pCi/g) of coal slag that present a risk for gamma exposure. Based on the gamma and alpha spectrometry analysis, an estimated 125 pCi/g of alpha emitters were concentrated in the coal slag that presented a risk for internal exposure due to inhalation and ingestion.
