Radiation Certification:
Certification or permit as required by the State Radiologic Health Branch for who is allowed to supervise and operate an X-ray machine.
Diagnostic Imaging:
Technique and process used to create images of the human body (or parts and function) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and physiology).
Radiation Licensing:
Users of radioactive material and persons possessing generally licensed devices containing radioactive material are required to be licensed and registered with the State Radiologic Health Branch.
Radiation:
Direct transmission of heat or electromagnetic energy through space or another medium. (example: X-ray)
Radiation Control:
Means and ways to limit unnecessary radiation exposure to the operator and the public.
Radiation Exposure:
The quantity used to indicate the amount of ionization in air produced by X-ray or gamma radiation while conducting radiologic procedures.
Radiation Safety:
The science of protecting people and the environment from the harmful effects of ionizing radiation, which includes both particle radiation and high energy electromagnetic radiation.
Radiation Shielding:
Reduction of radiation by interposing a shield of absorbing material between any radioactive source and a person, work area, or radiation-sensitive device.
Radioactive Materials:
Any material, solid, liquid, or gas, which emits radiation spontaneously.
Radioisotopes:
An unstable element that releases radiation as it breaks down. Also used in imaging tests or as a treatment.
Radiological Emergency:
An emergency where radioactive materials in significant concentrations escape into the environment. If the concentrations of the materials are high enough, they could be dangerous to health.
Radiology Regulations:
State regulations that includes licensing of radioactive materials, registration of X-ray-producing machines, certification of medical and industrial X-ray and radioactive material users, inspection of facilities using radiation, investigation of radiation incidents, and surveillance of radioactive contamination in the environment.
RHB (Radiologic Health Branch):
Primary State agency that is responsible for enforcing the laws and regulations designed to protect the public, radiation workers, and the environment.
X-ray:
A stream of high energy photons, used for their penetrating power in radiography, radiology, radiotherapy, and scientific research.
X-ray Contact:
List of Radiation Management staff contact information
X-ray Inspections:
On-site visits or inspections of facilities that possess any type of X-ray machine to verify compliance with Federal, State and local regulations.
Radioactive Materials Inspection:
On-site visits or inspections of facilities that possess any type of radioactive material
to verify compliance with Federal, State and local regulations.
Radioactive:
Material that emits radiation energy in the form of alpha, beta, or gamma particles or rays.
