The radioactive particles are small radioactive sources, which contain radioactive isotopes in a titanium tube, the two ends of which are welded by laser or electron beam technology to form a sealed source, the size of which is generally 0.8mm in outside diameter and 4.5mm in length. Nuclides commonly used for radioactive particles are192Ir、198Au、169Y、131Cs、103Pd and125i, etc., especially103pd and125I. the radioactive particles are directly implanted into the focus for close range continuous irradiation to destroy the DNA double bond of the tumor cell nucleus, kill or sublethal tumor cells and lose the replication capacity, so that the treatment purpose is achieved.
However, the radioactive particles used in clinical practice are mainly used for solid tumors suitable for radioactive particle implantation surgery, and for some important organs, glands and cavity parts which are not suitable for puncture, because the radioactive particles cannot be fixed at the focus part, brachytherapy cannot be performed by using the radioactive particles, particularly for organs with large cavities in the human body, such as stomach, uterus and other organ parts, the focus part is located on the cavity wall, and the treatment of the radioactive particles at the focus part cannot affect the normal physiological functions of the organs at the same time, which is a task which is almost impossible to complete, thus seriously hindering the application range of the radioactive particles.
