Use of fast x-ray film for low-influence biological electron microscopy at 100 kV and 1000 kV

Abstract

A user evaluation has been made by electron microscopists of an X-ray film for routine electron microscopy. The recent improvements in mammographic X-ray films, with the attempt to reduce the patient dose required to produce a high-resolution mammogram, have resulted in some useful films for medium- and high-voltage electron microscopy. They can yield essential cytological information with a reduction of the electron fluence (exposure) applied to the specimen of more than an order of magnitude compared with conventional electron-microscope films. Their use is indicated in situations where beam damage is severe.
