This is not the first time North Korea has had huge loss of life during their quest to advance their Nuclear Weapons Program. With the controls North Korea, China, and the Soviet Union have over their people, quality and safety concerns are severely lacking. Making incidents like this a lot more common than these countries will ever admit. Like rumors of Iran sending staff back into highly radioactive areas where centrifuges had been damaged during the malware attacks against the Iran nuclear weapons program. It's true that America has had some losses during its rapid growth to advance its own nuclear program. None even remotely close to the damage or loss of life the Communist or Dictator run countries have experienced.
