Reports that a group of Saudi scientists had made an unusual declaration about the biological classification of women originated as satire. Social media posts circulating widely on Facebook in July 2020 falsely suggested the thermometers are aimed at the same “exact point” as the pineal gland and could be exposing it to some sort of harmful radiation or infrared light. The thermopile is nothing but thermocouples connected in series or parallel. Remote mounting possible from the hot target.

Lead Stories is a fact checking website that is always looking for the latest false, deceptive or Some social media users also speculated on why the thermometers were allegedly targeting the pineal gland — a tiny gland that produces melatonin, among other hormones, and has colloquially been called the “third eye.”, “For century’s the pineal gland has been connected with spirituality,” read one Facebook post, “and thought to be the means of communicating with God.”. “It’s just a catcher. Ford has more than a decade of news experience, including several years spent working in Latin America. For infrared thermometers, the accuracy depends on its distance-to-spot ratio (D/S ratio). The higher the temperature, the faster the molecules move. Infrared light works like visible light it can be focused, reflected or absorbed. THE FACTS: Non-contact infrared thermometers that are held up to a person’s forehead have become popular during the COVID-19 pandemic as businesses and governments seek ways to detect possible infection without risk of transmission. The Food and Drug Administration has more information about these devices, and how they can be used safely and effectively, on its website. However, the radiation can jump to the visible spectrum if the object gets too hot. AP’S ASSESSMENT: False. } It is designed to detect and absorb the infrared light signals from the surface of the skin and convert it to electricity signals. They pose no risk to the pineal gland, which is located deep within the brain, according to Dr. Haris Sair, director of neuroradiology at Johns Hopkins University. The detector uses this output to determine the temperature, which gets displayed on the screen.

Namely, it states that the pineal gland is located "directly in the center of the forehead." It's not. Still, such lasers would not be penetrating. .top-level { It means that with bigger ratios, you can measure the temperature from a farther distance. Anything at a temperature above absolute zero has molecules inside of it moving around. Some infrared thermometers include a laser to direct the placement of the tool on its target, but it has no purpose related to measuring temperature, according to Robinson. Fact Check: Non-contact infrared thermometers that measure body temperature when held up to a person’s head have become popular amid the ongoing COVID-19 pandemic. The heat that we feel from sunlight, a radiator, or a fire are all examples of infrared radiation.
