Radiation Safety

All UW units are required to inspect radiation personal protective equipment (RPPE) provided for employee protection; follow the requirements in the Inspecting Radiation PPE Focus Sheet.

There are a number of basic safety considerations for personnel using nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI) and other superconducting magnetic equipment,

A superconducting magnet uses two types of cryogens (liquid helium and liquid nitrogen). Cryogenic liquids can be handled easily and safely, provided certain precautions are followed as outlined in these instructions. 

Radio Frequency Safety Exposure Categorization describes control measures and required signage for four categories of exposure to radiofrequencies.

The Ultraviolet (UV) Safety guidance covers UV devices generally found in research laboratory, hazards, safety precautions and recommended controls, including PPE, and warning signs and labels..

The Laser Safety Procedure addresses alignments, maintenance and normal operations procedures; all hazards; types of PPE; and emergency procedures associated with the particular laser system.

Visit the Laser Safety page for more information.

A laser pointer contains a small diode laser that emits an intense beam of light often used for directing attention during a presentation. Follow these safety considerations when using a laser pointer.
