Kiyoshi Kikkawa, a 33-year-old man, was exposed to the atomic bomb in front of his home, about 1.5 km from the hypocenter, on August 6, 1945.

     The entire back of Kiyoshi Kikkawa, who still has keloidal burns from the heat of the Hiroshima atomic bomb, is photographed at Hiroshima Red Cross Hospital on April 30, 1947.Kiyoshi Kikkawa, a 33-year-old man, was exposed to the atomic bombing of Hiroshima City on August 6, 1945, in front of his home about 1.5 km away from the hypocenter. He was hospitalized at the Hiroshima Red Cross Hospital in February 1946 and underwent about 16 surgeries, including skin grafts, before being discharged in April 1951 while receiving public assistance. A photograph taken on April 30, 1947 was featured in Life magazine and other publications as "ATOMIC BOMB VICTIM NO. 1 KIKKAWA" (Atomic Bomb No. 1).

  The shoulder, arm, and back burned by the heat rays of the Hiroshima atomic bomb have raised flesh scars and keloids, and the surgical scars are fresh. Masaru Kuroishi (who died in 1990 at the age of 77), an X-ray technician at the Hiroshima Red Cross Hospital, took the photographs as a medical record before and after treatment under the direction of doctors. He began taking photographs of the pathological conditions of A-bombed patients at the Hiroshima Red Cross Hospital (now the Hiroshima Red Cross and Atomic Bomb Survivors Hospital) in October 1945, about two months after the atomic bombing by the U.S. military on August 6, 1945.

　Masaru Kuroishi's photography was also under the direction of Deputy Director Fumio Shigeto and his colleagues. He and his colleague Seiji Saito, a pathology technician, recorded the effects of the atomic bombing on the human body. Some patients at the hospital were so injured that they could not even be identified by gender. Fumio Shigeto, the director of the hospital, told me to take various photographs, but my conscience got the better of me and I couldn't do it." Despite his conflicted feelings, he took nearly 50 photographs as a medical record.

  In addition to the direct deaths of tens of thousands of people, the atomic bombings of Hiroshima and Nagasaki resulted in a series of horrific consequences that have long characterized the entire region. Within a year of the atomic bombings, many people died from radiation and burns, and in the years that followed, many Japanese died of cancer and birth defects due to the radiation released by the very bombs.

In early October 1945, he was admitted to Hiroshima Army Hospital No. 1. Due to acute symptoms of radiation damage caused by exposure to the atomic bomb, most of the hair on his head had been lost from the front, sides, and back of his head.

 　Japanese Army soldiers exposed to the atomic bomb were interned at the camp for the injured of the Army Ship Training Department, located in Ujina, about 4 km south-southeast of the hypocenter of the Hiroshima atomic bomb, and in early October 1945, they were admitted to Hiroshima Army Hospital No. 1. Due to acute symptoms of radiation damage caused by exposure to the atomic bomb, most of the hair on their heads had been lost from the front, sides, and back of the head. The main symptoms of the third to fifth week of acute damage to the human body were hair loss, hemorrhage including purpura, and lower hemorrhage, causing death with general weakness.

　Ujina, Hiroshima, was a port area, more than 3 km from the hypocenter, and suffered relatively little damage from the atomic bomb. The people who had been exposed to the atomic bomb in Hiroshima rushed to this area, which had survived the fire. One of the facilities that provided aid to the injured in Ujina was the Army Ship Training Depot. The Army Ship Training Department was an organization that provided education and training in ship operation to army units, and was stationed in the confiscated Daiwa Spinners Hiroshima factory. Since the number of troops receiving training was constantly changing, the barracks were not always full. There was also a stockpile of food, so there was no shortage of meals for about 1,000 people. At 8:15 a.m. on August 6, an atomic bomb was dropped on Hiroshima, and although the building was slightly damaged by the explosion, it was not seriously damaged. About an hour later, the injured began to arrive. By 3:00 p.m. on August 6, several hundred A-bomb survivors had been admitted to the hospital. The Army Ship Training Department became what should be called a field camp. Many of the inmates were seriously ill with A-bomb disease, and from August 10 to mid-September, approximately 3,000 people died.

　The Army Ship Training Center, which had been a field camp, was reorganized by order of the Ship Command and became the Army Ship Training Center Temporary Field Hospital on August 12, and with the defeat of Japan on August 15, the military wartime system was liberated. On August 25, the nameplate of Hiroshima First Army Hospital Ujina Branch was hung. During this period, the Army Ministry Investigation Team entered the area on August 8, and the 2nd Investigation Team on August 14. Using the Ship Training Department as a base, they were engaged in the investigation of the atomic bombing.

At the Japanese Red Cross Hiroshima Hospital, in early October 1945, A-bomb survivor Toshiko Sasaki was treated for burns to the skin on her lower left leg at the Hiroshima Hospital of the Japanese Red Cross Society. The house had collapsed, and she suffered multiple wounds to her tibia, skull cracks, and soft tissues, especially in her left lower leg knee area, which was compressed by the beam material.

   At the Japanese Red Cross Hiroshima Hospital, Toshiko Sasaki, an atomic bomb survivor, was treated for burnt skin on her lower left leg around early October 1945 at the Japanese Red Cross Hiroshima Hospital. Toshiko Sasaki was exposed to the Hiroshima atomic bomb and received her injuries at Toyo Steel, 105 Tenma-cho, Hiroshima City. She was sitting on a chair at work when she saw the glow of the Hiroshima atomic bomb and sat down to sit down. The house collapsed, and he was compressed by a beam, especially in the knee area of the left lower limb, resulting in multiple wounds to the tibia, cracks in the skull, and soft tissues. She was admitted to Hiroshima Hospital of the Japanese Red Cross Society. There was no nerve damage, and automatic motion of the left thumb was possible, but severe contracture of the knee joint was observed. He was in passive position of the left lower limb due to pain during exercise. Blood test at the Japanese Red Cross Hospital showed that his white blood cell count was 6200.

　The Japanese Red Cross Hiroshima Hospital, which became the Hiroshima Army Hospital Red Cross Hospital during the war, was located in Sendamachi 1-chome, Naka-ku, Hiroshima City, 1.6 km south of the hypocenter. All wooden buildings on the site collapsed and were soon destroyed by fire. The main building, a three-story reinforced concrete structure, escaped destruction by fire. Steel window frames were destroyed and glass shattered into pieces. The interior of the building was also destroyed, with ceilings falling, walls crumbling, and chairs and desks toppling over, making it difficult to set foot inside.

　Shunkichi Kikuchi took photographs of A-bomb survivors. He graduated from the Oriental School of Photography in 1938 and joined Tokyo Kogeisha, and in 1941 joined the photography department of Tohosha. In October 1945, about two months after the atomic bombing, photographer Shunkichi Kikuchi accompanied an A-bomb documentary film accompanying a survey of the damage by experts and photographed a number of A-bomb survivors in Hiroshima City In September 1945, he accompanied a survey team organized by the Academic Research Council of the Ministry of Education to photograph the A-bombed city of Hiroshima. From October 1 to 20, 1945, he accompanied the documentary film production team of the Special Committee for Investigation and Research on the Atomic Bombing Disaster organized by the former Ministry of Education to take still photographs.

Exposed to the Hiroshima atomic bomb on August 6, 1945, the man's back began to develop keloids; in 1947, the Hiroshima atomic bomb burns left keloid scars on the man's back.

 広島原子爆弾に1945年8月6日に被爆して、男性の背中にはケロイドが発生してきた。1947年には、広島原子爆弾の火傷で男性の背中にケロイド状の傷跡が残存していた。生き残った被爆者には、ケロイド状の恐ろしい火傷を負った。極度の熱射でひどく焼かれて、特徴的なケロイド状の傷跡ができた。そのケロイドの瘢痕は最初の火傷よりも大きくなる。ケロイドは、原爆の被爆による火傷した皮膚が治癒する過程で形成された。不規則で異常に突出した瘢痕組織である。瘢痕が蟹の甲羅や足のように見えてケロイドと呼称された・爆心地から約2km以内の被爆者に多く見られ、ケロイドは被爆約4ヵ月後に形成され、その後に6～14ヵ月後に最も膨隆した。瘢痕は、被害者の皮膚が炸裂の初期閃光の熱に直接さらされた部位に形成された。ケロイドは被災者の心と体に永久的な傷跡を残した。顔にケロイドができた人は精神的な苦痛が大きく、背中や肩にケロイドができた人は肌を見せるのをためらった。夏でも長袖のシャツを着ている人が多かった。

　1945年8月6日、アメリカが広島に原爆を投下し、78,000人が即死した。生き残った人々は放射線病と重度の火傷を負い、街は完全に破壊された。広島に原子爆弾が投下された約1秒後に、直径約280メートルの巨大な火球が噴出した。その中心部の温度は摂氏約100万度を超えた。原子爆弾の爆発による熱線は、通過するすべてのものの表面温度を最悪で摂氏3,000度以上にも上昇させる。突然の急激な温度上昇は、周囲の空気を急速に膨張させ、音速を超える爆風を発生させた。爆風の背後の空間の気圧の低下により、進路にいる被爆者の眼球や内臓を破裂させるほど強力な逆流が発生した。爆心地から約1km以内のほとんどの被爆者は即死した。それよりも遠方の被爆者は、街の建物の破片を浴びせられた。

　爆発によって発生した放射線のほとんどはガンマ線で、その他10％は中性子線であった。どちらもDNAに変化をもたらす電離放射線の一種である。中性子の方がはるかに危険であった。広島原子爆弾の呼称であるリトルボーイの約64kgのウランの約10%は最初の核分裂反応によって食べ尽くされた。残りの約90%の放射性物質は爆風によって広島市内に撒き散らされた。その放射線被曝の結果、被爆者の多くは、嘔吐、発熱、疲労、歯ぐきからの出血、薄毛、下痢などの放射線症のは原爆病に襲われた。原爆病の苦しみ、最悪の場合は原爆病死に至った。生き延びた被爆者は、その後にがんのリスクが高まった。その子孫に異常が見られたという証拠は不明である。
