ABSTRACT:A comparison is made between IRAS observations of dust emitting in the 60- and 100-micron FIR bands and H I and CO surveys covering the
entire Milky Way.
It is suggested that most of the FIR luminosity of the
Galactic disk in the 60 and 100-micron bands at R greater than 2 kpc originates
from dust associated with neutral atomic gas and molecular gas heated by the
general interstellar radiation field.
It is found that the FIR dust
emissivity per nucleon decreases dramatically with increasing Galactocentric
distance.
