On the web some think Dr. Akazuki was a Hiroshima Dr. and worked in those fields of death. It confused me as to where he was a doctor for not long, yet causing me to think of a potential via a science equation that Hiroshima fields also as well as Nagasaki received from LITTLE BOY u235 bomb a dose of plutonium pu239 along with plotonium pu240. This by the fact that there was15 lbs of inert uranium u238 contained in 140 lbs of fission explosive weapons grade uranium u235 core of LITTLE BOY. That equation ='s creation of fission creates dense neutron clouds of slow and fast neutrons and within the two categories of neutrons differences. Of the slow neutron fields created inert uranium u238 captures a slow neutron and changes to plutonium u239. An exploding uranium u235 bomb is fission and an exploding plutonium pu239 bomb is fission, both creating dense neutron fields to change inert uranium u238 into plutonium pu239. There was only 15 lbs of uranium inert u238 in the core of LITTLE BOY u235 fission material bomb. Some of the u238 would have captured a neutron as LITTLE BOY fission exploded and became plutonium pu239 and most of that pu239 would have fissioned in the explosion with the uranium u235 to e= mc to the second power and to other elements. Yet some of the plutonium would have remained raw plutonium dust and been captured on the ground of Hiroshima. A very small quantity. It is worth looking at (perhaps) in terms of Gulf War Syndrome in terms of evaluation of Hiroshima soil although most of this small quantity of plutonium would have been blown upward and into the world. With FAT MAN fusion hydrogen bomb over Nagasaki it used weapons grade plutonium pu239 in its core in a quantity of 13 pounds of which only 2 pounds fissioned into e=mc to the second power plus other elements created. Thus 11 pounds of pure raw plutonium unfissioned was blown into plutonium dust. This poor fission value was already seen by Robert Oppenheimer by necessity of thinning down the side walls of the outer depleted uranium tamper of the bomb to enable FAT MAN to be dropped through the B 29 bomber bomb hatch and to decrease weight that the plane would not roll over into the Pacific ocean. The thin depleted uranium side wall is shown here  http://www.nationmaster.com/encyclopedia/Fat-Man  (Wikipedia says this depleted uranium tamper did not fission but Robert Oppenheimer included it in his equation as fissioning to the value of providing an extra 4kt, and it did fission. The confusion possibly being that tamper fissions are included or considered as part integral of the core fission material. But Oppenheimer held them seperate.) The tamper holds in fission to peak or maximise fission in TNT explosive equivalency value then the tamper uranium included as part of the central core of the bomb fissions but at a poor value as it is only 0.4% fissionable e=mc to the second power uranium 235 plus the inert u238 which comprises 99.6% of the tamper in the fissioning in a small percent captures a slow neutron and changes to plutonium pu239 most of which fissions along with the u235 although some remains raw plutonium that is blown into dust. In the case of FAT MAN bomb over Nagasaki the depleted uranium tamper weighed over a thousand pounds but by its intentional final design of weak side walls did not permit towards complete fission and maximun TNT explosive equivalency value.                                                                                                          In a hydrogen fusion bomb such as IVY MIKE of the south pacific testing that same quantity of depleted uranium would yield 1 megaton of TNT explosive equivalency value. Atop the IVY MIKE silo http://www.aracnet.com/~pdxavets/wetokian/wheeler.htm  was a small Oppenheimer compression fission nuclear bomb called the trigger bomb which blew down a channel surrounding a 10,000 pound casing of depleted uranium which in turn surrounded a giant flask or dewar of heavy hydrogen cryogenic towards absolute zero liquid of 1,000 liters and at absolute center of the silo a pure hollow weapons grade 30 foot plutonium pipe bomb rising vertically in the center of the 1,000 liters of deuterium in the absolute center of the IVY MIKE silo with its belching hydrogen flame for escaping deuterium gas out a vent pipe and the robot deteurium feeder Sleet Sue receiving regular replacement dewars or flasks of cryogenic deuterium from Perry island. With tritium extra heavy hydrogen gas and deuterium heavy hydrogen gas inside the hollow plutonium pipe. The IVY MIKE silo was of an outside 1" steel casing laminated on the inside with a layer of lead to absorb for one millionth of a second the fissioning down the channel of the exploding Oppenheimer bomb, the lead absorbing for that millionth of a second the fission energy of the Oppenheimer bomb that energy mainly soft x-radiation to cast the differental of pressure-heat towards the depleted uranium interior casing fissioning differentially and implosion of the secondary depleted uranium casing surrounding the cryogenic 1,000 liters of deuterium and vertical 30' plutonium pipe bomb, the depleted uranium both imploding and fissioning intensely compressing the plutonium pipe to fission at outer heat of the sun value and the tritium and deuterium gas within the hollow plutonium pipe creating fusion to the inner core heat of the sun. In the inner core heat of the sun neutron clouds are dense fast neutrons which inert u238 does not capture and change to plutonium pu239 but simply fission explodes when struck by these fast neutrons. Thus the depleted uranium of 10,000 pounds fission-fusion exploded producing 8 megatons TNT equivalency value by the depleted uranium alone. The entire U.S. government supply of tritium was contained in the 30 foot vertical plutonium pipe called the "spark plut".this bomb which president Truman had ordered to be built immediately and quickly. The U.S. had at the time grave trouble producing tritium (extra heavy hydrogen  T  H3).  But as the spark plug to creat fusion it worked and as the Japenese have informed us the coral atoll is a rare lithium mine (they want them to produce lithium batteries of which they are number one world producer) and as fission and fusion upon lithium changes lithium to tritium more necessary tritium was produced in the fusion explosion and incorporated into the fusion as was the abundant deteurium (heavy hydrogen  H2  D) in the ocean waters.                                                                                                      Not all of the 10,000 pounds of depleted uranium u238 was exploded by fast nutrons of the inner heat of the sun fusion. Some of it remained the natural raw u238 inert harmless dust 99.6% u238 and 0.4% u235. There were also slow neutrons that some of the uranium u238 captured to change to uranium pu239 which was incorporated into the explosion. Yet some of this plutonium created out of the depleted uranium by fission remained raw natural plutonium dust and most went upward and was scattered about the globe.                                                                                                         The Russians responded by attempting to create a bomb 1,000% more powerful than IVY MIKE and nearly succeeded and with the bomb they did produce - which was very big - feared they had blown a hole into space through which some of the earths air escaped before the atmosphere closed in upon itself. The U.S. never tried to duplicate or outdo that Russian hydrogen bomb. And Russia thinks no more about it.
