Many late-type galaxies in the Virgo and Coma clusters  show
 abnormally high ratios between the radio continuum and the FIR
 emission compared to field galaxies, violating the tight
 correlation between the two emissions which universally holds
 for field galaxies without a bright AGN. Possible interpretations
 are (1) an additional radio emission from AGNs, (2) stripping of
 dust in the disk by the ICM, and (3) the radio emission of CR
 electrons accellerated by shocks generated in galaxy/ICM
 interactions. The latter two interpretations, which are related
 to the galaxy/ICM interaction in clusters, are more likely,
 although not necessarily unrelated to the former. In order to
 distinguish between them, we propose to map the FIR emission with
 ISO PHOT for five Virgo late-type galaxies listed in Table 1. They
 have radio/FIR ratios more than a factor of 3 higher than the
 mean of the field galaxies. These FIR maps will be compared with
 the corresponding radio maps to study the distribution of the
 radio/FIR ratio in the galactic disks. The central region
 around the nucleus will have the highest ratio
 if any AGN is responsible, while the ratio should
 be high in the outer disk if the dust stripping is
 the mechanism. The shock triggered by the galaxy/ICM interaction
 can be identified by a high radio/FIR ridge located somewhere
 in the outer part of the disk. Such investigations can only be
 done with ISO because the angular resolution of IRAS was not
 high enough to spatially resolve any clustered galaxies, and the
 sensitivities of KAO and ground-based MIR telescopes are too low.
