Radiation Control 

The Radiation Control Section promotes the safe and effective use of ionizing radiation and the protection from unnecessary exposure through education and regulation of licensees, registrants, and the public.

The Section regulates the use and possession of accelerators, radioactive material and x-ray equipment in the State of Arkansas.

  • Individuals administering ionizing radiation to humans are licensed by the Section’s Radiologic Technology Licensure Program.
  • The use and possession of radioactive material is licensed by the Section’s Radioactive Material Program.  Academic and Industrial Accelerators are also licensed by this Program.
  • The use and possession of x-ray equipment is regulated by the Section’s X-ray & Mammography Program.  This regulatory oversight is performed through registration and compliance inspection.  Medical Accelerators are also licensed by this Program.
  • Facilities performing mammography are accredited by the Section’s X-ray & Mammography Program.
  • Radiological Incidents involving radioactive materials and/or Arkansas Nuclear One (ANO) events require on-site emergency response by a cadre of Radiation Control Section Health Physicists.


Visit the U.S. Environmental Protection Agency’s student-focused radiation website, RadTown.  This interactive, virtual community provides information for students and teachers about different radiation sources.  RadTown also provides Radiation Education Activities for middle and high school students (grades 6-12) which include lesson plans covering radiation basics, sources of radiation, radiation protection, exposure versus contamination, radon, and more.

Also, you can check out the Health Physics Society’s webpage for teachers.  Here you will find information on the following:  basic reference materials concerning radiation, fact sheets that explain radiation-related topics of current interest, demonstrations and classroom activities, lesson plans, careers in radiation safety, and radiation measurement instrumentation.

The Health Physics Society sponsors an additional website that is dedicated to public education. Radiation Answers contains objective, scientific information about radiation in a friendly, easy-to-read format.
