一、前言随着核技术在科学研究、工业、农业、医药卫生及国防等部门的应用日益增加,周围环境的放射性水平不断提高,给人类的健康造成了严重危害。核污染问题已成为全球性不容忽视的大问题。钚是应用最广泛的核原料之一,因此钚的污染就成为当前的一个严重问题。钚是亲网状内皮系统的放射性核素。它不仅具有很强的化学毒性,而且由于其α粒子能量大,滞留体内的钚会对人体的组织器官产生强辐
I. INTRODUCTION With the increasing application of nuclear technology in scientific research, industry, agriculture, medical, health and defense departments, the radioactivity in the surrounding environment has been continuously raised, which has caused serious harm to human health. Nuclear pollution has become a global issue that can not be ignored. Plutonium is one of the most widely used sources of nuclear materials, so plutonium pollution has become a serious problem at the moment. Plutonium is a radionuclide of the pro-endothelial system. It not only has a strong chemical toxicity, but also because of its alpha-particle energy, retention of body plutonium will produce strong human tissue and organs
