Dive Summary:

• The reason why two goldfish were found in a juice pitcher in an underground steam tunnel at the Perry nuclear power plant near Cleveland, Ohio has finally been solved.
• Two contractors were pulling a prank, plant officials confirmed Friday. "Normally, no one is allowed in that area because of the potential for radiation exposure, but the reactor was shut down for routine maintenance," the Associated Press reported.
• The goldfish didn’t create a safety hazard, but harmed the plant's reputation. The Perry plant was already being investigated for its worker training and procedures.

From the article:
“Tests found that the goldfish were swimming in reactor water and only had slightly detectable radiation levels. They died after their discovery.”
