This is John Batcher, conversation with my colleague Charles Pellegrino,

author of To Hellen Back, previous title was in called Last Train from

Hiroshima.

It's about the attack on Japan by two atomic weapons, August 6, 1945, August 9, 1945.

And how the central government in Tokyo of warlords learned that it was an atomic weapon. They sent a physicist

to Hiroshima the day after the attack, August 8th, Japan time, August 7th, U.S. time.

And what he did and how he tested in the information he carried to Tokyo.

And the important detail, we have no defense. All of that contributed to war end. in Here is Nashina finding evidence of an atomic weapon, Hiroshima, 1945.

More of this later tonight.

That was Dr. Nashina and he was flown in ironically by the pilot who led the raid on Pearl Harbor.

He had radiation detection equipment.

He went right to the hyper center he found a street corner where

what was left of the people under the hyper center near the famous T bridge were

basically people were reduced to teeth, radioactive teeth.

And once he, within minutes he detected that there was radiation coming from these teeth and he said we've got to go back to Tokyo

we've got to tell them that this weapon was atomic and there is no defense against this.
