"Alpha and Beta radiation, for example, are quite harmless"
...unless the source is ingested or inhaled, in which case they become extremely dangerous.
(I´ve quoted wiki here, because sometimes I can´t express my thoughts in english.)
Guess why they are wearing those suits and a gas mask - it´s not about gamma.
But isn't radiation all around us in the nature as well? As far as I have read they even use radiation to "mark" the gulf stream to measure it's movement. And what about the radiation coming from cole mining?
Yes, and we can´t do anything against the natural radiation.
Afaik it´s about 2-2,5 mSv per year here in germany.
The radiation of colemines and old coal-fired power stations is quite large.
In the long way we need a switch to renewable energy.
But we can´t compare natural isotopes with man-made, enriched isotopes that are
coming out of a containment with a propably half melted core when it comes to half-life and impact.
Let's just hope for the best and donate as much as possible.
