遇到核爆
似乎要服用碘??
但是那種東西有人吞的下去嗎? =,=
還是有加味的 XD
知識上找的
高溫和衝擊波的能量是會隨著距離的平方成反比遞減,
故遞減得很快。若在幾里外的低地,生存的機會會很大。
其中一個防核彈的方法是挖地道並躲在裡面。
衝擊波只在地面傳播,泥土又是良好的熱絕緣體,又可阻擋輻射射線,
故在幾里外已能能抵受核爆的傷害。
當然,若原子彈在頭上爆炸便無人能倖免,
因爆炸做成的真空已可使人死亡。
殘留的輻射粒子就比較麻煩,
這些輻射粒子通常是有放射性的碘-131
(iodine-131, a radioactive isotope of iodine),
故原爆倖存的人要服食碘片,以防止身體再吸收碘-131引致甲狀腺癌。
