Abstract
In an earlier paper,1 we compared the efficiency of electron and photon beams for determining microchemical environment. The conclusion, that electron beam systems might have higher sensitivity than a photon beam system when analyzing submicron size areas, is in fair agreement with the assessment by J. Kirz2 in which various beam spectroscopies were compared with regard to elemental identification of biomaterials. Estimates concerning the relative damage imparted to the sample by ionizing beams were made in (1) and (2) using somewhat different assumptions. However, no effort was made to assess the radiation damage due to a spectroscopic measurement. [Although in (3), comparisons (for electrons) of doses necessary to acquire given statistics in a spectroscopic measurement were compared to the doses at which manifestations of damage occurred.]
