Non-Ionizing Radiation Safety Program


The Lawrence Berkeley National Laboratory (Berkeley Lab) Non-ionizing Radiation (NIR) Program is designed to provide a safe working environment for staff that ensures NIR exposure does not exceed the Threshold Limit Values (TLV) for the human eye or skin. The NIR Program at Berkeley Lab ensures personnel are protected from NIR exposure hazards including:

  • Infrared light
  • Magnetic fields
  • Microwave radiation
  • Radio frequency
  • Artificial ultraviolet (UV) radiation
  • Visible light

Note: Laser and acoustic (noise) exposures are covered in separate policies.


This program applies to Berkeley Lab employees, casual and participating visitors, affiliates, and subcontractors who may perform work in or around NIR sources with the potential for over exposure.
