"Burned off" may be occupational jargon for Radon decay to daughter isotopes which are not inert.

"Burn up" refers to the reduction in the percentage of U235 in the fuel rods in a nuclear power reactor resulting from the fission process during operation.

I wonder what " burned off radon" means since Radon is an inert gas.
