Artificial and natural sources of IR radiation are examined and common occupations with potential for IR exposures are noted. Biological effects on eyes and skin are described. Industrial data on ocular IR radiation hazards among workers is presented.
Infrared radiation waves are the same as heat waves. Laser beams are composed of highly amplified electromagnetic radiation (visible light, microwaves, infrared and others). These lasers can be strong enough to burn a hole through metal and so could certainly damage flesh. Extremely powerful lasers are even being developed by the military for ...
In the US, federal standards limit the amount of RF radiation that can leak from a microwave oven to a level far below what would harm people. Ovens that are damaged or modified, however, could allow microwaves to leak out, and could pose a hazard to people nearby by possibly causing burns.
IR-A radiation with its excessive heat can cause irreversible damage (such as burns) to the retina and cloud the lens, which can lead to a cataract (also known as glassblower’s cataract or infrared cataract). IR-B radiation can damage the blood vessels down to the fatty tissue.
Far infrared (FIR) radiation (λ = 3–100 μm) is a subdivision of the electromagnetic spectrum that has been investigated for biological effects. The goal of this review is to cover the use of a further sub-division (3– 12 μm) of this waveband, that ...
Infrared (IR) radiation is electromagnetic radiation with wavelengths between 760 nm and 100,000 nm. Low-level light therapy (LLLT) or photobiomodulation (PBM) therapy generally employs light at red and near-infrared wavelengths (600–100 nm) to modulate biological activity.
Mid and far-IR are progressively further from the visible spectrum and nearer to microwave radiation. There are two potentially significant hazards associated with IR radiation: Thermal effects. Infrared waves are given off by all warm objects and produce heat in all objects they strike.
Infrared radiation (IR) is the portion of the electromagnetic spectrum between visible light (VL) and microwaves, with wavelengths between 700 nm and 1 mm. Humans are mainly exposed to ultraviolet (UV) radiation (UVR) and IR through the sun.
Infrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. Invisible to the eye, it can be detected as a sensation of warmth on the skin. Learn more about infrared radiation in this article.
Near infrared waves are short and not hot — in fact you cannot even feel them — which is what makes them particularly dangerous to susceptible tissues, such as skin and eyes. Skin exposed to IR provides a warning mechanism against thermal effect in the form of pain. Eyes, on the other hand, may not.
