Radiation-resistant sealing materials are materials that can maintain effective sealing performance in radiation environments. These materials typically need to possess characteristics such as radiation resistance, chemical corrosion resistance, heat resistance, and good sealing performance to meet the requirements of working under radiation conditions.

The selection of radiation-resistant sealing materials depends on the specific application's radiation dosage, operating temperature, pressure, and environmental requirements. When choosing and applying these materials, factors such as radiation stability, chemical corrosion resistance, high-temperature resistance, etc., need to be considered to ensure sealing performance and safety reliability. Additionally, compliance with relevant standards and specifications should be ensured.
