how to reduce background reflection?
(OP)
We are trying to measure a surface temperature of a body accurately. The body is put in an enclosure to reduce reflection on the body from background objects with a different temperature. Should this enclosure have a high or low emissivity to further reduce reflection effects from the enclosure (which will have a different temperature from the body) itself on the body?

Is your object's emissivity reasonably high?, otherwise, you'll still have problems will seeing the correct radiance.
Why IR? The accuracy is somewhat limited for objects with complicated spectral characteristics.
How accurate are you trying to get? A well calibrated PRT or even a thermistor will achieve better than 0.1 deg C, which is difficult to achieve radiometrically.
