Radiation Safety

Radiation Machine (X-ray)

A radiation machine is any device capable of electrically producing ionizing radiation (the term excludes devices containing radioactive material).

Radioactive Material

Radioactive material is any material (solid, liquid, or gas) that emits radiation spontaneously and exceeds a quantity listed in the Rhode Island Code of Regulations: Title 216, Chapter 40, Subchapter 20, 7.9.2.

Radiofrequency

Radiofrequency refers to radiation in the 3 kilohertz (kHz) to 300 gigahertz (GHz) region of the electrometric spectrum. 

Magnetic Fields

Magnetic fields refer to a strong static magnet, a nuclear magnetic resonance (NMR) system or a magnetic resonance imaging (MRI) system.

Laser Safety

A laser is defined as any Class 3B or Class 4 laser system or high intensity light source.

Extremely Low Frequency

Extremely low frequency refers to electric and magnetic fields in the 1 hertz (Hz) to 100 kilohertz (kHz) region of the electrometric spectrum.
