Just how much radiation the Pseudomonas got is hard to estimate, because the water circulates at varying distances from the core of the reactor, but Dr. Fowler thinks they may have absorbed more than 10 million rep (roentgen equivalent physical) in an eight-hour day, which is 10,000 times the dose that is fatal...
