If a radioactive zombie dies on the meteor space and was not killed by a fire item, I understand that he leaves radioactive residue and all future fights in that space result in rolling 1 die less then normal.
2 related questions:
Does the radioactive residue also effect attempts to damage the meteor during the fight zombies phase of the hero(s) turn?
Can you attempt to burn the residue on a space in order to remove it from the board?
Yes to both
