The theoretical parameters of cryogenic calorimetric detectors of vari
ous types and their values achieved experimentally are reviewed. Such
devices are claimed to show great promise as a means for recording low
-energy neutrinos. Experimental schemes for detecting events of elasti
c neutrino scattering on electrons and nuclei are proposed. The expect
ed frequency of detection of sought events are calculated for a labora
tory situated near the core of a nuclear reactor.
