Radiation in therapy refers to the transfer of energy in the form of what, without physical contact?

• A. Infrared Waves Radiant Energy
• B. Sound Waves
• C. Electrical Currents
• D. Magnetic Fields

Answer: (A)

Radiation in therapy means energy that is transferred without physical contact, traveling through space to reach and affect tissues. Infrared energy is a classic form of radiant energy used in therapy; infrared waves move through air or a lamp’s gap and are absorbed by the skin to heat the underlying tissues. This non-contact transfer is what distinguishes infrared therapy from modalities that rely on direct contact or a medium to transmit energy. Sound waves, electrical currents, and magnetic fields all involve different modes of energy transfer or interaction that typically require a medium or a device in contact with the body, not pure radiant energy traveling through space.
