...Roger D. Lewis; Jason Kennedy; Mason Andruskiewicz; Christopher A. Brown; Sridhar Condoor A need exists to develop realistic surfaces, with differing degrees of surface roughness, to standardize methods for sampling and cleaning of environmental contaminants. This study reports on development...

... in place of air sampling for a variety of reasons. Chief among them is that many indoor allergens settle to the ground quickly after being released. Another reason for the wide-spread use of surface over air sampling for indoor air allergens is that air sampling is typically performed over a limited time...

...Kevin Ashley; Michael J. Brisson; Kenneth T. White This article summarizes the body of available standards for sampling of chemical and biological agents on workplace surfaces, including skin. These standards consist of voluntary consensus standards such as those promulgated by ASTM International...

...MJ Brisson, MSc; AA Ekechukwu, PhD; K Ashley, PhD; SD Jahn, CIH Since the U. S. Department of Energy (DOE) published the DOE Beryllium Rule (10 CFR 850) in 1999, DOE sites have been required to measure beryllium in air filter and surface wipe samples for purposes of worker protection...

...D Campling; B Patel This paper describes the sampling and analysis of beryllium at the Joint European Torus (JET) fusion facility. The current policy requiring 100% personal air sampling (PAS) and taking many surface contamination smears generates 40 000 samples per year. Sample processing...

...K Ashley; MJ Brisson; SD Jahn Conformity in methods for sampling and analysis of beryllium in workplace air and on surfaces is desired, but inconsistencies in sampling and analytical practices often occur among industrial hygienists and laboratory personnel. In an effort to address these issues...

... and lowest absorptions out of all sampling locations considered. On the other hand, material in the middle layer and closest to the split face displayed lowest flexural strength and elastic moduli and highest absorptions. In addition, the SRW material also exhibited anisotropy with respect to flexural...

... significance of these observed variations and the implications of such variations on sampling and test result interpretation. It was demonstrated that the observed spatial variations were statistically significant along the casting direction (parabolic distribution) and in a direction away from the split face...
