From a technical or statistical perspective I know nothing about the issue. But from a laymans point of view I have concerns about how the overall global back ground radiation energy levels may have been effected by the use of Nuclear energys both in the form of explosions, power plants and most especially nuclear fall out from failed reactors such as the one in eastern Europe at *Chenobyle* (spellings). Could some one tell me if they know what the effect is? Also if some one knows what the current status is of "Chenobyle" reactor I would greatly appreciate it. maybe there is a url link i can use?
