小男孩（英語：Little Boy）是第二次世界大戰時美國在日本廣島市投擲的首枚原子彈的代號。於1945年8月6日由保羅·提貝茲駕駛的B-29超級空中堡壘轟炸機「艾諾拉·蓋」在廣島相生橋上空31,000英尺（9,400米）投下，日本標準時間早上8時15分在1,800英尺（550米）高度爆炸。
簡介[编辑]
「小男孩」是人類歷史上首次投入实战的核武器，另一枚對人類使用的核武為投擲在長崎的鈈原子彈胖子。小男孩長10英呎（3米），寬28英吋（71厘米），重8,900磅（4,000公斤）。使用「鎗式」設計，將一個富含鈾的空心圓柱體（“子彈”）以炸藥射到相同材料的固體圓柱體（“目標”）上，造成整塊超臨界質量的鈾，引發核子連鎖反應[1][2]。小男孩裝有64公斤的鈾-235[3]，其中不到一公斤進行了核分裂[4]，釋放的能量約等於13,000公噸的 TNT烈性炸藥，即大概為6.3×1013 焦耳。約七萬人直接死於小男孩的原爆，大約同等數量的人受傷。隨後再有大量的人死於核子塵埃放射引起的癌症。懷孕的母親亦因為放射而出現流產，部分初生嬰兒發育畸形。
据統計，直到1999年，死于小男孩原子彈的直接襲擊及核輻射傷害的人數總計已超過20万。
由於時間緊絀而未能提煉足夠濃縮鈾製作試驗彈的情況下，小男孩這種設計的核武器在使用前並未進行過實際試驗。美國於1945年7月16日在新墨西哥沙漠試爆的第一枚原子彈是以鈈為原料。當時美國的濃縮鈾只足以製造一枚鈾核彈。
