DESCRIPTION:*Abstract*\nWith the widespread use of field-emission sources 
 and aberration-corrected lenses\, radiation damage in the TEM becomes a pr
 oblem even for conducting specimens. \nWe have performed experiments and c
 alculations of electron-induced sputtering in order to better estimate the
  rate and incident-energy threshold of this form of damage. Previous EELS 
 measurements of radiation damage in polymers suggested a remarkable reduct
 ion in damage in the case of small-diameter electron probes. I will show r
 esults that confirm these claims and discuss some possible interpretations
