近几十年来,人类一方面享受了放射性核素应用技术的成果和经济效益,但同时也受到因此而产生的辐射内污染的威胁。而要减少和免除这种不良的副作用,必需阐明各种不同放射性核素对人体的内照射危害及其安全限值。于是,放射毒理学就成了一门在放射医学中极为重要的学科。目前,由于研究工作的进一步深化,各学科间的互相渗透,使内污染放射毒理学的研究内容,已从对本代健康影响的观察,进而深入发展到对下一代危害的研究,派生出了放射遗传毒理效应这个重要的分支研究,从而建立了以保障人类安全为目的的新概念。
In recent decades, human beings have enjoyed the fruits and economic benefits of radionuclide application technologies on the one hand, but at the same time they have also been threatened with intra-radiative pollution. To reduce and eliminate this undesirable side effect, it is necessary to clarify the hazards of internal radiation and the safety limits of various radionuclides. As a result, radiotoxicology has become an extremely important discipline in radiology. At present, due to the further deepening of the research work and the mutual penetration among disciplines, the content of research on the radioactive toxicology of pollution has been studied from the perspective of the health effects of the present generation, and further developed into the study of the harm of the next generation, Genotoxic effects of this important branch of the study, thus establishing a new concept for the protection of human security.
