It should be pointed out that this concentration is marginal with respect
to the detection limits of the counting systen.
The estimated thyroid dose from radioiodine inhalation at Shoshone was
less than 0.1 mrad.
The integrated exposure at the location of highest

TRITIUM RESULTS
Increases in tritium concentration in the off-site environment have been
noted following several events
(e.g.,
Cabriolet and Buggy I).
In addition
to these events, the aerial sampling program has detected tritium in the
effluents from the Nash and Scroll Events.
The intent is not to imply
that these are the only events to have released tritium, but rather to
use these results to obtain an indication of the potential hazard offOE ARCHIVI
