In Canada, various federal acts govern non-ionizing radiation by originating source, such as the Radiation Emitting Devices Act, the Canada Consumer Product Safety Act, and the Radiocommunication Act. [56] For situations not under federal jurisdiction, Canadian provinces individually set regulations around use of non-ionizing radiation. [57]
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine.
Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).
Sonicision, the industry's first cordless ultrasonic dissection device, is a hand-held, pistol-grip style, battery-powered surgical ultrasonic device that is indicated for soft-tissue incision and ...
A long-range acoustic device in use on the USS Blue Ridge Sonic and ultrasonic weapons ( USW ) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound ; others produce an area field of sound.
Electronic harassment, electromagnetic torture, or psychotronic torture is the delusional belief, held by individuals who call themselves "targeted individuals" (TIs), that malicious actors are transmitting sounds and thoughts into people's heads, affecting their bodies, and harassing them generally.
