Studies have been performed on the use of shortwave radiation for cancer therapy and promoting wound healing, with some success. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues, for example by overheating or inducing electrical currents.

Microwave burns are burn injuries caused by thermal effects of microwave radiation absorbed in a living organism.. In comparison with radiation burns caused by ionizing radiation, where the dominant mechanism of tissue damage is internal cell damage caused by free radicals, the type of burn caused by microwave radiation is by heat—health effects colloquially associated with the term ...
Technically, microwaves do emit “electromagnetic radiation,” but according to Dr. Arya Amini, associate professor and chief of thoracic radiotherapy at the City of Hope National Medical Center ...
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
A microwave oven is an example of this principle put to controlled, safe use. Radio-frequency (RF) energy is non-ionizing electromagnetic radiation – its effects on tissue are through heating. Electronic components are affected via rectification of the RF and a corresponding shift in the bias points of the components in the field.
The above effects have only been shown to be due to heating effects. At low power levels where there is no heating effect, the risk of cancer is not significant. [9] [10] The International Agency for Research on Cancer recently stated that there could be some risk from non-ionizing radiation to humans. [11]
The red ionizing radiation warning symbol (ISO 21482) was launched in 2007, and is intended for IAEA Category 1, 2 and 3 sources defined as dangerous sources capable of death or serious injury, including food irradiators, teletherapy machines for cancer treatment and industrial radiography units. The symbol is to be placed on the device housing ...
Project Pandora studied the effects of occupational radiation exposure, and the project's scientific review committee concluded that microwave radiation could not be used for mind control. [22] Conspiracy advocates also frequently cite the 2002 Air Force Research Laboratory patent for using microwaves to send spoken words into someone's head ...
