In research fields such as life sciences, radiation biology, and pest control technology, precise, safe, and controllable irradiation methods are fundamental to many critical experiments. Leveraging its expertise in X-ray technology, Dandong Tongda Technology Co., Ltd. has developed the WBK-01 X-ray Irradiator, designed to provide a modern alternative to traditional radioactive isotope sources for various laboratories. I. Core Principle and Design Purpose The equipment operates by accelerating electrons through a high-voltage electric field to strike a metal target (e.g., a gold target), thereby generating high-energy X-rays. This design of an "electrically generated radiation source" fundamentally avoids the use of radioactive isotopes like Cobalt-60 (Co-60) or Cesium-137 (Cs-137), eliminating the long-term custody, substantial decommissioning costs, and potential safety hazards associated with source materials. II. Core Product Features High Safety: No Radiation When Powered Off: X-rays are only generated when the equipment is powered on and operating. There is no residual radiation after operation, significantly reducing laboratory security and management costs. Multiple Safety Interlocks: Equipped with multiple safety protection features including door-operation interlock, emergency stop, and overdose protection, ensuring the safety of operators and the environment. Precise Control and Good Reproducibility: Utilizes a digital control system, allowing users to precisely set irradiation parameters—including voltage (kV), current (mA), and irradiation time—via a touchscreen interface. The system enables stable dose output, ensuring uniformity in experimental conditions and reproducibility of results. Easy Operation and Simple Maintenance: The user interface is simple and intuitive, easy to learn and operate, lowering the barrier to use. Compared to isotope sources which require regular replacement and decay monitoring, the main maintenance for this equipment focuses on the periodic replacement of the X-ray tube, resulting in relatively fixed and manageable long-term maintenance costs. Flexible Sample Compatibility: The irradiation chamber is designed to accommodate various samples, from cell culture dishes and multi-well plates to small animals (e.g., fruit flies, mosquitoes, or mice). 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. It does not pursue excessive features but focuses on providing a stable, reliable, compliant, and easy-to-manage irradiation tool for scientific research and industrial applications. For laboratories seeking alternatives to isotopes or planning to establish new irradiation platforms, this is a practical piece of equipment worthy of evaluation and consideration by users in basic research and applied fields.

Principle of X-ray irradiator: The X-ray tube in the X-ray irradiator generates high-energy electrons, which produce X-rays when they collide with the target material (usually tungsten). Accelerating electrons through a high-voltage electric field to obtain sufficient energy to generate the required X-ray wavelength and intensity. Then, the X-rays are adjusted and optimized through a series of collimators, filters, and other devices, and finally irradiated onto the sample. The main components of an X-ray irradiator are: The X-ray irradiator mainly includes X-ray tubes, high-voltage generators, control circuits, cooling systems, safety protection devices, and sample rooms.
