nuclear chess

i propose to make new variant similar to atomic chess, but it is a bit different.   when you eat a piece with your peice, your pice explodes like a nuclear bomb and leaves radiation 

 After a real nucliear explosion, the radiation stays there for a while and police does not let anybody in that zone until the radiation is gone. So the radiation will stay unrtil another ten moves are made. The radiation is invisible. There are maximum 4 squeres with radiation. If there are already four radioactive squeres both players can not eat a piece unti a squere is no more radioactive. 

And a precision, if you are check and your only move is to eat a peice but all 4 squeres are allready radioactive, it is a checkmate. 

some players advised to leave the squere as a brick intead of radiation

thank you

can you put your multiple. posts into 1

I feel as though ten moves is too many, maybe five moves?
