【摘要】：近年來,隨著恐怖事件頻發(fā),利用放射性物質(zhì)進(jìn)行核恐怖襲擊的可能性越來越大。其中,放射性"臟彈"事件是利用放射性物質(zhì)擴(kuò)散進(jìn)行破壞的核恐怖活動(dòng),一旦發(fā)生,造成的后果將較為嚴(yán)重。分析了放射性"臟彈"可能的組成種類與作用效應(yīng),在此基礎(chǔ)上模擬計(jì)算了典型場景下放射性"臟彈"的放射性劑量。按模擬所得平均值,煙羽吸入內(nèi)照射途徑是放射性物質(zhì)作用于人體的主要方式,占平均總有效當(dāng)量劑量的99%左右;而地面沉積外照射途徑貢獻(xiàn)了第二多的總有效當(dāng)量劑量,地面沉積外照射與煙羽外照射只占總有效當(dāng)量劑量的1%左右。同時(shí)分析了放射性"臟彈"對人體、環(huán)境可能造成的后果。
[Abstract]:In recent years, with the frequent occurrence of terrorist incidents, the possibility of using radioactive materials to carry out nuclear terrorist attacks is increasing. Among them, the radioactive "dirty bomb" incident is a nuclear terrorist activity which is destroyed by the spread of radioactive material. Once it occurs, the consequences will be more serious. The possible composition and action effect of radioactive "dirty bomb" are analyzed, and the radioactive dose of radioactive "dirty bomb" in typical scene is simulated and calculated. According to the simulated average value, the internal radiation pathway of plume inhalation is the main way for radioactive substances to act on the human body, accounting for about 99% of the average effective equivalent dose, while the surface deposition external irradiation pathway contributes the second largest total effective equivalent dose. Only about 1% of the total effective equivalent dose was caused by external irradiation of surface deposition and plume. At the same time, the possible consequences of radioactive "dirty bomb" on human body and environment are analyzed.
