The current commercial operational reactor is outputting isotopes right into an east wind; see the charts. Yakima is, ironically, in the plume shadow.
The Columbia Generating Station (former WPPSS site) is also on the Hanford 'site'.
It's amazing to me that all this data & research spans 40+ years and they're still reticent to give any credence at all to what, for some doctors & scientists, is already well-established.
Wasn't Hanford originally a military research site? And that's how they got away with covering up their filth? I heard the Hanford story years ago... and have forgotten most of it....
