NIST researchers identify a cheaper, more convenient method to detect asbestos - EurekAlert
Transmission electron microscopy (TEM) has long been the gold standard for detecting asbestos fibers in air samples drawn at construction sites. But researchers at the National Institute of Standards and Technology have found that a cheaper, less labor-intensive method, scanning electron microscopy (SEM), can work just as well in most cases. The new finding could help reduce the estimated $3 billion spent on asbestos remediation in this country every year.
