radio isotopes. for the iodine, simply don t drink the milk. not like you use cows and milk production as an example of one way you can be contaminated, that s the specific route? that s the specific route. iodine pills aren t going to do harm, but they won t help. the real problem is people need to stop drinking the milk. we talked about radiation sickness. this is something we mostly think about for people working inside fukushima s nuclear plant at this point, trying to stop that. in terms of symptoms and prognosis they are likely to be undergoing, what will authorities be watching for, and what can they do for people significantly exposed. this isn t anything that s going to affect anybody outside japan and probably nobody outside the plants, i worry about the people and think of them because we all depend on them getting their jobs done. absolutely.
the blast injured four workers, crumbled concrete walls and is heightening fears of a nuclear meltdown. joining us again, edwin lyman. clear this up for us. are we heading towards a meltdown? when we say meltdown we start thinking chernobyl, we start thinking three mile. yes. i think that the events are definitely heading toward a meltdown. this is why the japanese authorities are trying to resort to measures like injecting sea water into the reactor to try to cool it down. th does seem to be like a last ditch measure. we do know that there has been a loss of cooling capacity to some extent for more than a day now, and that could have a very serious effect on the radioactive fuel and we do know that there has been some damage to the fuel because of the detection of certain radio isotopes outside of the plant.
the coast lines. we have 600 miles of coastline they have to protect and they have a radiation track boat. they can detect radio isotopes in any form. what they are looking for in particular is freighters are ships that might be coming in with something like dirty bombs. so these particular machines can detect radiation. if you and i just came from a doctor and had radiation they can detect that small amount of radiation inside of us. heather: time for one more question. what about what we weren t allowed to see? anything that we weren t allowed to see? quite a bit. that what makes the city so safe. they have huge throughout the city, camera system like london they also have areas where they are constantly watching under cover and counter intelligence
