Ray-Bar Neutron Shielded Doors are lead lined and/or borated polyethylene (BPE) filled cores with steel faces and edges. For over 40 years, Ray-Bar has custom manufactured neutron shielded doors to suit each individual linear accelerator radiation / oncology project requirement based on linear accelerator energy output, radiation type, orientation to radiation sources, primary beam configuration and overall room design. We manufacture sliding or hinged doors in new and retrofit applications weighing up to 40,000 lbs. each. Neutron door composition requirements should be determined by a qualified health radiation physicist. See Ray-Bar Neutron Shielded Door Specification for more information or contact us.

Ray-Bar Neutron Shielded Doors,High Radiation Doors and Linear Accelerator Vault Doors meet all applicable requirements of the National Council on Radiation Protection and Measurements NCRP report# 51 "Radiation Protection Design Guidelines for 0.1-100 MeV Particle Accelerator Facilities" and NCRP report# 151 "Structural Shielding Design and Evaluation for Megavoltage X-Ray and Gamma-Ray Radiotherapy Facilities".

Door shielding material composition requirements must be determined by a qualified health radiation physicist expert as defined by local and national codes.
