Huma infrared termometri perikolużi?
Qi Haiyan, deputy chief physician of the Department of Ophthalmology at Shunyi Women and Children's Hospital of Beijing Children's Hospital, said that if the intensity of infrared rays is high, it will irritate and damage the eyes, and in severe cases, it can cause cataracts, retinal damage, and even blindness. The eyes have a certain absorption effect on infrared rays with a wavelength of less than 1.5 microns. If the eyes are directly irradiated, the liquid in the eyeball will react due to the absorption of short-wave infrared rays, causing eye diseases. "However, infrared thermometers on the market do not emit infrared rays. The red light emitted is for convenient positioning. Its working principle is to measure by receiving infrared wavelengths from the heat emitted by the human body. Qi Haiyan further explained that the human body is at 36 degree - The infrared wavelength emitted at 37 degree is 9-13 microns, which is the self-radiation wavelength of the organism. The higher the temperature of the object, the shorter the emitted wavelength. For example: when the temperature of the object reaches 300 degree , the emitted infrared wavelength is 6.8 microns , and the highest human body temperature is a little over 40 degree . At this time, the emitted infrared wavelength is greater than 6.8 microns, which is much higher than the wavelength range that the eyes can absorb (1.5 microns), so it is safe for the human body to emit far infrared rays. Infrared measurement Thermometers are divided into two types: contact and non-contact. Since the main route of transmission of new coronary pneumonia is through respiratory droplets and close contact, the current use is non-contact to avoid the infection of new coronary pneumonia due to contact. Non-contact infrared The thermometer will measure different parts, such as the forehead, neck, wrist, etc. Using an infrared thermometer to measure the neck will not have any effect on the thyroid gland. Qi Haiyan believes, "Measuring the wrist is the most convenient and fast. Please cooperate during the epidemic. Measure body temperature, use infrared electronic thermometer with confidence. "
Does l-infrared termometru have radiation?
Il-prinċipju ta' l-infrared termometru huwa li is-sħana tal-bniedem il-korp se jkun jinħeles f' l-ambjent in il forma ta' termali radjazzjoni. Il bniedem infrared termometru skoperti skoperti il termal radjazzjoni ta' il bniedem korp through the built-in sensor, so as to achieve the purpose of measuring body temperature. Il infrared termali immaġni korp temperatura rapidu screening strument użi infrared temperatura kejl teknoloġija għal malajr miżura il- wiċċ temperatura tal il bniedem korp in a non-kuntatt manner, u it huwa strument li iwissi meta il imkejjel temperatura jilħaq jew jaqbeż il-preset twissija temperatura valur.
Allura bażikament il bniedem korp infrared termometru innifsu se le għandhom ħafna radjazzjoni.
