Dirty hydrogen bomb - Dirty hydrogen bomb


[3F Bomb]
A weapon that has 238 U around a hydrogen bomb, which is then fissified by a large number of high-speed neutrons produced by a nuclear fusion reaction, further enhancing the explosive energy. After serving as a neutron reflector and tamper, the 238 U is involved in a fission reaction, which results in an increase in residual radioactivity and is therefore called a "dirty hydrogen bomb." The name 3F bomb comes from the initials of the three nuclear reactions that occur during the explosion: fission of the atomic bomb used for the detonation, fusion of deuterium, and fission of 238 U. …

*Some of the terminology that refers to the "dirty hydrogen bomb" is listed below.

[3F爆弾]
 水素爆弾の周囲に238Uを配し,核融合反応によって生じた多量の高速中性子によって238Uを核分裂させて,さらに爆発エネルギーを強化した兵器。238Uは中性子の反射材およびタンパー材として役割を果たしたのち分裂反応にあずかるが,この結果残留放射能を増大するため〈きたない水爆〉といわれる。3F爆弾の語源は,その爆発過程である起爆用原爆の核分裂fission,重水素の核融合fusion,238Uの核分裂fissionの3段階の核反応の頭文字をとったものである。…
