Radio waves are a form of electromagnetic radiation with frequencies ranging from about 30 kilohertz (kHz) to 300 gigahertz (GHz) that are used in various medical applications, such as diagnostics (MRI) and therapeutic (radiation therapy) procedures.

A Radio Frequency Identification Device (RFID) is not a traditional medical term, but it can be used in medical contexts as a technology that allows for contactless data transmission between a reader and a tag using radio waves, which can have applications in areas such as inventory management of medical supplies or tracking patient movement within a healthcare facility.
