Targets of ThCx and UCx have been used for production of Fr, Ra(Ac) nuclides of astrophysical interest at the IRIS mass separator on line with the 1 GeV proton synchrocyclotron at LNPI. A fine-grained powder of a target has been prepared using a special technology based on high temperature destruction of the thermostable organometallic compounds of U, Th or Cm (diphtalocyanine). New neutron-rich nuclides have been identified: 232Fr (5 +/- 1 s), 233Ra (30 +/- 5 s), 234Ra (30 +/- 10 s). The yields of some nuclides from a CmCx target have been also determined.
