What is the fundamental principle of UNH’s Radiation Protection Program?

Only UNH faculty may become Radioactive Material User Permit
      Holders.
All individuals who handle sources of radiation must complete a
      Radiation Safety for Users training program prior to any handling.
Levels of radioactivity used and exposures to all sources of
      ionizing radiation are maintained as low as reasonably achievable
      (ALARA).
Permit Holders are responsible for ensuring that all individuals
      entering their laboratories/work areas have received appropriate
      radiation safety training.
