Diathermy equipment can interfere with which of the following?

Diathermy equipment can interfere with which of the following?

• A. Radio frequencies
• B. X-ray beams
• C. Visible light
• D. Sound waves

Answer: (A)

Diathermy uses high-frequency electrical energy in the radiofrequency range to generate heat in tissues. That RF energy can radiate and capacitively or inductively couple into nearby radio-frequency systems, causing interference with RF devices and communications. X-ray beams, visible light, and sound waves operate in entirely different parts of the spectrum (ionizing radiation, optical wavelengths, and mechanical waves, respectively), so they aren’t directly affected by the RF energy from diathermy. Hence, the interference concern is with radio frequencies.
