The sample stage can be designed to rotate, ensuring uniformity in radiation dose distribution. III. Main Application Scenarios Biomedical Research: Used for creating immunodeficient animal models (e.g., ablating bone marrow cells in mice), inducing cell apoptosis, synchronizing cell cycles, oncology research, and pre-treatment for stem cell transplantation. Sterile Insect Technique (SIT): This is a significant application area. It can be used to irradiate pupae of agricultural pests (e.g., Mediterranean fruit fly) or mosquitoes to render them sterile, thereby supporting green, pollution-free population control programs. Material Modification Research: Can be used to study the effects of X-rays on the properties of various materials (e.g., polymers, semiconductors). IV. Typical Model Parameters (Using WBK-01 as an example) X-ray Tube Voltage: Adjustable based on requirements, typically within a range from several tens to hundreds of kilovolts (kV), to suit different penetration depths and dose rate needs. Dose Rate: Can be adjusted based on voltage, current, and distance to meet the specific requirements of different experimental protocols. Uniformity: Ensured through optical system design and a sample rotation mechanism, guaranteeing uniform dose distribution within the irradiation field for reliable experiments. Summary The core value of the Dandong Tongda X-ray Irradiator lies in its replacement of inconvenient radioactive isotope sources with a safe, controllable, electrically generated X-ray source.
