核武器爆炸后所产生的早期核辐射和放射性落下灰,均可对人员造成全身外照射;当食入沾染的食品、水和吸入沾染的空气时,会引起体内的照射;放射性落下灰直接沾染体表后,则可发生体表的乙射线照射。机体受到内、外照射后,是否会产生损伤及损伤的程度,与受到的照射剂量大小有关。在核战争条件下遭受敌人核武器的袭击,或部队需要通过或停留在放射性沾染区 Early nuclear radiation and radioactive fallout from nuclear explosions can cause extra-corporeal exposure to personnel; exposure to in-vivo exposure to contaminated food, water and inhalation of contaminated air; ingestion of radioactive dust directly into the body Table, then the body surface may occur B-ray irradiation. Body by internal and external exposure, whether the damage and damage will occur, and the size of the exposure dose. Attacks by enemy nuclear weapons under conditions of nuclear war or troops need to pass or remain in radioactive contamination areas
