Hm... Thanks Kathleen. It is nice to read, because I'm originally from Ukraine (Kiev), but it is really strange that participants were chosen from 4 to 18 years old group, because I think that more influence were on the year of the Chernobyl disaster, because more radiation was spread in this period. Also it is strange to compare Kiev with Chernobyl, because as I know that Kiev was also pretty affected by disaster and radiation. It will be interesting to see comparison between Ukrainian children and other children (not affected by disaster).And now I'm thinking that maybe my IBS is also caused by it?! Do they also talk about cure and how to fix it?
