Dose Limit News Today : Breaking News, Live Updates & Top Stories | Vimarsana

What a great school to be coming from. i want to ask you, i want to stay very organized here, how much exposure is safe for human being, doctor? >> well, there are effective dose limits set by the international commission of radiation protection and the ncrp which is our commission here in the united states. that upper dose limit is five milisievert. just to put this in a perspective, a chest x-ray would give you about 0.1 milisievert the question you asked is different. i'm glad you did ask it. there is no such thing as a safe dose. this is the dose limit that we think based on mathematical m...

There was concern about what happened to two people during another explosion today. let's talk about the radiation levels inside the plant. at this point, from what we know how much trouble are the guys in? what kind of danger could they be facing? >> i don't know what the exact levels. i had in front of me a report from the international atomic of course all the data provided from the japanese nuclear safety energy agency. there was a report earlier yesterday that the rates were about 11.9 milisevers per hour. that's about two and a half times the annual -- the upper dose limit for annual exp...

Dose. this is the dose limit that we think based on mathematical modeling could be set at. we get cosmic rays which is about 2.4 milisevrs a year. there is no such thing as a safe dose. >> are americans at risk for radiation coming from japan? >> could you repeat the question? >> are we at risk in north america from what's happening in japan right now in terms of the dangers of meltdown in those four reactors over there? >> i think that would be highly unlikely. i think that just learning from the chernobyl experience, the

The question you asked is different. i'm glad you did ask it. there is no such thing as a safe dose. this is the dose limit that we think based on mathematical modeling could be set at. we get cosmic rays which is about 2.4 milisieverts a year. the dose/response curve, especially with the long-term effects it -- doesn't have a threshold. there is no such thing as a safe dose. >> are we at risk none continent with what's happening in japan right now in terms of the meltdown and the four reactors there? >> i think that would be highly unlikely.

>> well, as far as the acute effects of radiation go, they typically would affect only a very localized group of people, those in the vicinity of the reactor and, of course, there have been reports of a very high -- i think there was a news release in front of me from the nuclear industrial safety agency in japan indicating that right by the reactor, by the northwest of the site boundary monitor there was a reading of 231 mcper hour. you would need to be exposed to 20 years continuously of that in order to reach the dose limit that is set for the general population at 5 milli see verts for a w...
