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

1. 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.

2. 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.

3. 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.

4. 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.
