The authors have studied the effect of thermal radiation on measurements of the thermal conductivity of small samples below room temperature. By using the different thermal conductivity technique they were able to measure the importance of these effects for temperatures greater than about 100K and to determine the principal source of error of the double flux correction, i.e. the different heater temperature with each different heat flux. They thus propose a better configuration for performing such measurements.
