worked on three mile island cleanup and on the class action lawsuit resulting from that disaster in the 1990s. mr. gunneder son, thank you for joining us. >> thank you for having me. >> are the leaks associated with this reactor potentially more dangerous than the leaks from the other three shut down reactors? are the radioactive particles released from a damaged spent fuel rod worse than what's released from damaged fuel rods and reactor that's been shut down? >> the damage from the fuel rods has long lived isotopes. that fuel has been sitting around a long time, and the short-lived isotopes like iodine are no longer there, so what is there is sees yum, stron see up, plutonium and other long lived isotopes. what's happening close to that reactor is probably really powerful gama rays, like an x-ray.
