A scanning infrared radiometer proved to be an effective method of accurately assessing radiative heat loss from nude and clothed subjects in temperatures of 0 to -35 degrees C. The radiometer is sensitive to infrared radiation between 1.8 x 10 to the 4th power and 10 x 10 to the 4th power A, and traces a corresponding picture in visible light which is recorded on polaroid film. Experiments were conducted with five subjects wearing various clothing assemblies. The pictures show the critical importance of wrinkles, insulation compression, and the excessive heat loss which occurs from the head and extremities. (Author)
