protective clothing and their use in the assessment of the thermal strain at work. In
order to study the effects of the asymmetry of long wave thermal radiation on the
heat transfer through protective clothing, the heat loss under all-side and unilaterally
applied radiation with the same incident radiant power of 279 W/m2 was measured
with a thermal manikin and compared to a reference condition where mean radiant
temperature was equal to air temperature. With exposure to radiation a lowered heat
loss, i.e. heat gain for the whole covered body area was observed, which did not
depend on radiant asymmetry for the dry as well as for the combined dry and
evaporative heat loss, and which was attenuated when wearing a more insulating
underwear. However, under one-sided radiation a more inhomogeneous spatial
distribution occurred with higher heat gains and higher surface temperatures at the
irradiated body parts.
