Global Fire Maps

What this means is that the airborne radioactivity can essentially double the dose to the fire personnel from inhalation of the radioactive materials. i.e., they are being irradiated both from outside and inside whereas the "normal" radiation exposure is only external when you are in the Chernobyl zone. The airborne contamination doesn't much change the existing amount on the ground ( it goes up and then comes back down) but, as previously noted, it might disperse over greater distances, albeit at lower concentrations because of dilution.]
