Intelligent Storage Decay System For Radioactive Waste Liquid In Nuclear Medicine
The radioactive waste liquid is characterized by many types and high concentrations of radioactive isotopes, radioactivity, and great harm to humans and animals. However, the traditional radioactive waste liquid treatment can only rely on a rough understanding of the half-life of radioactive waste liquid natural decay treatment, Gemei technology independently developed for nuclear medicine, radioactive waste liquid intelligent storage decay system, with decay dynamic real-time monitoring, process display, information storage and other functions.

The radioactive wastewater produced in the hospital is mainly the domestic sewage produced by the patients injected with radionuclides. The domestic sewage generated in the patient's special toilet and other restricted areas is collected through special pipes to the decay tank of the nuclear medicine department. Trough decay and multiple monitoring and treatment are adopted. After sufficient decay, the radioactive waste water discharge limit can be discharged after detection.
This radioactive waste liquid monitoring and treatment discharge system is specially designed and developed for the workplace where radioactive waste liquid is produced, which meets the national environmental protection requirements and is widely used in industrial, medical and other radioactive places. According to the half-life of radionuclide drugs used in the nuclear medicine nuclide treatment ward area and the outpatient imaging area, two sets of long and short half-life nuclei can be designed in parallel Prime decay pool.
