If you place your finger below a kettle, to prevent it being affected by convection, it will feel warm because of the warm radiation, and if you place it above and ice cube it will feel cold because of the cold radiation.

No. It will feel cold because of the lack of warm radiation.

If the level of radiation that your finger is receiving is greater than
the level it is emitting, your finger will (feel) warm. Conversely, if
your finger is emitting more energy than it is receiving, it will (feel)
cool.

I thought we had cleared this up last time.

Your cold radiation and your warm radiation are the same thing. They are
just at different energy levels.

Hot water and cold water are the same thing. That does not mean cold water does not exist.
