Xenon-133 measurements were x450,000 our detection levels using a SAUNA-II xenon measurement system
Noble gas does not “washout,” and is the first emitted from any possible fuel damage
Levels persisted for weeks and isotopes were ultimately detected across the northern hemisphere and around the world
