They should send him over to Japan. He could walk right into a highly radio active area and simply brush it off when he came out. He must be immune to any radiation by now
Judging from that picture of him at the bottom of the article he doesn't look like he's too immune to radiation
I've got to give the kid credit though. He must have been very dedicated to his work. To painstakingly collect enough radioactive material from everyday incidental sources to build a crude "breeder reactor" in his back yard is quite an accomplishment, albeit dangerous.
