Which statement about diathermy safety and radio frequencies is true?

• A. It may interfere with radio frequencies
• B. It never interferes with electronics
• C. It only interferes with infrared devices
• D. It is unrelated to radio

Answer: (A)

Diathermy safety hinges on the fact that diathermy devices emit energy in the radiofrequency range. That RF energy can radiate beyond the treatment area and couple into nearby radio receivers and other electronics, causing interference or malfunction. Because of this, interference with radio frequencies is a real safety concern in a clinical setting, and it can affect communication devices, monitoring equipment, and other sensitive electronics in the room. It isn’t true to say there is never interference, nor that it only interferes with infrared devices, nor that it’s unrelated to radio—the RF energy is what makes interference possible. To minimize risk, clinicians plan treatment spaces with shielding and adequate distancing from RF-sensitive equipment and follow device-specific safety guidelines.
