Internally deposited radioactivity

BRAWM Team I realize this is a bit outside your usual bailywick, but I was wondering if you have any estimates or science to assess internal dose to the two workers at Fukushima http://mdn.mainichi.jp/mdnnews/news/20110530p2g00m0dm069000c.html "The two workers have been involved in dealing with the plant's Nos. 3 and 4 reactors. At a measurement on May 23, their thyroid glands were found to have absorbed 7,690 and 9,760 becquerels of radioactive iodine-131, respectively, 10 times higher than data on other workers." Being that the monitoring was done on 5/23, what do you think? Any Idea what their internal dose is?.. I understand if you decline. You are all doing a great job!!
