Refractory ceramic fiber asbestos. Rcf is not asbestos while rcf is often compared with asbestos it is chemically and physically different from asbestos and is not a substitute for asbestos. Asbestos is crystalline while rcf is amorphous without a clearly defined shape or form. The aim of this study was to investigate the hypothesis of an increased risk of pleural mesothelioma due to co exposure to asbestos and refractory ceramic fibres rcf compared to asbestos exposure alone. Rcfs are less durable biopersistent than amphibole asbestos but more durable biopersistent than many other synthetic.
This method may be used for other materials with alternate counting rules. There was no increase in lung cancer or mesothelioma in these workers exposed to rcf. Asbestos occurs naturally while rcf is man made. Asbestos fibers thinner than about 0 05 0 15 µm diameter depending on asbestos type will not be detected by this method 7 10.
If the me thod is used to detect a specific type of fiber any other fiber may interfere because all particles meeting.
