This ring contains roughly 90,000 people. Less than one half (25,000) of the indoor population will be killed inside buildings, mainly by flying debris. Many of the rest (40,000) will receive injuries to varying degrees. Those outside at this range escape serious direct injury from the blast overpressure but may be injured or killed by flying objects. The thermal pulse has been attenuated to well below 1 cal/sq. cm., posing the danger of temporary flashblindness to those looking in the direction of the blast, but nothing more.
