Abstract: The applications of nuclear physics,which include nuclear analytical techniques,isotope technology,and ion beam technology,play an important role in industrial and agricultural production.Ion beams,electron beams and isotopic radiation sources are widely used in radiation detection,radiation processing,irradiation sterilization,radioactive treatment of seeds,radioactive eradication of insect pests,radioactive preservation,etc.Through a correct understanding of nuclear radiation and a good grasp of the basics of radiation protection,new technological applications of nuclear physics will become an important part of human life.
