VOID FRACTION MEASUREMENT.
Abstract
One hundred and thirty-nine references on various methods of void fraction and film thickness measurement were reviewed and indexed by subject. Since the radioactive particle attenuation techniques were the most frequently employed method for measuring void fraction, these techniques were studied in detail. The conclusion of this detailed study is that accurate measurements of void fraction are feasible when small diameter, low and mono-energetic photon beams are employed. Such requirements generally will exclude the use of radioisotope gamma ray sources but will not exclude radioisotope beta-ray sources. Much of the published void fraction data using radioactive isotope sources is in error by
