DO you think winds blowing over Japan can carry radio active material ?

Question:

If yes , how far such radio active material can get transported via wind ?

Answer:

Yes wind and rivers can transport radioactive materials from one place to another.Winds blowing over japan are westerlies(blows from west to east) but due to the local temperature and pressure conditions the radiation can reach parts of neighboring countries like Russia,China,Philippines,Koreas...(which are on the west ). Alpha and beta radiation particles do not travel far , they are easily blocked. By contrast, gamma rays, x-rays, and neutrons travel a significant distance and are much more difficult to block .The materials used in the nuclear power plants are radium, uranium, thorium ,plutonium,these elements are alpha radiation emitters .If radioactivity from the reactors is released to the upper atmosphere it would be thinned out by the winds enabling them to travel greater distances...today first particles spewed from wrecked Fukushima power station reached US west coast(California) which is located thousands of miles away from Japan.
