高能辐射以及放射性核素日益广泛地应用在工业、农业、国防的各个部门。射线技术、放射性示踪剂、活化分析等已渗透到化学、生物学、物理学、医学、地质学、考古学等各门学科领域。因此,熟悉并正确使用放射性强度单位和辐射剂量单位,不仅对专业研究者是有意义的,而且对从事与放射性有关的一般工作者也是十分必要的。 High-energy radiation and radionuclides are increasingly used in various sectors of industry, agriculture and defense. Radiation technology, radiotracer, activation analysis, etc. have infiltrated various disciplines such as chemistry, biology, physics, medicine, geology and archeology. Therefore, familiarity and proper use of radioactive intensity units and radiation dose units are not only of interest to professional researchers, but are also essential for those working in general with regard to radioactivity.
