radiation scare stories again
Anything to do with radiation automatically becomes a scare oout of proportion to the real threat.
He will presumabely be treated with I131 this has a half life from memory of about 8 days and is a gamma and beta emitter. The gamma rays havea fairly high energy (for nuclea rmedicine anyway) of around 360 keV so will easily penetrate his body.
Whatever he has ingested has already decayed by a factor of 8. In addition some material will have been excreted. The beta radiation will not penetrate his body leaving the gamma exposure to police or the public. Studies of the radiation exposure to the family members and pets! of therapy patients show that doses recived over two weeks are an order of magnitude below safety limits.
Given that the material will have decayed by a factor of 8 and the possible exposure time is going to be no more than a few hours the 'threat' already well within safety limits is going to be roughly one thousandth of an already insignificant hazard. Actually this is obvious, people are routinely treated in this way as out patients and it is considered quite normal and safe.
The story does contribute to the general scare mongering and paranoid fantasy about anything radioactive, dirty bombs etc.
