| 520 | $aMost analyses for asbestos in samples from the non-occupational environment are carried out using techniques based upon either scanning (SEM) or transmission (TEM) electron microscopy. The mode of image formation and resolution obtainable differ between SEM and TEM and the present study was undertaken in order to provide some indication of the comparability of observations made by the two techniques, with particular reference to the visibility of fine, submicrometre fibres. The results indicate that, in general, at a given magnification finer fibres are visible when using TEM than when using SEM | ||
