Ultraviolet and covid

[rupol2000]

There is information that ultraviolet light kills viruses, but I have not seen anyone using radiation for disinfection in public places. Is it used massively in the USA?
This is another argument in favor of this is a scam.
Why they are not used it massively against Covid?
They could disinfect stores, restaurants, transport, and so on, just like they do in hospitals.

Back awhile when everyone was freaking out over covid, the big box stores started selling handheld UV disinfecting devices. Most of them ended up on the closeout and discontinued items shelf. Some hand dryers in bathrooms have a UV light that comes on when you're drying your hands. Those are about all I've seen anywhere.

UV will kill any and all viruses quite effectively.
This has been known for many years. It is why they have UV lights in water purification.
Hospitals and Dental offices use UV lights to disinfect all kinds of things. Some hospitals are employing "UV rooms" - essentially it is a hospital room that is equipped with overhead UV lights. Once a patient has left, they use the lights overnite to kill everything in the room.
Many hospitals across the U.S. have been using UV light stations to treat masks etc. to reuse the next day

Indeed. UV sterilization has been used in water treatment for decades.

Because Trump suggested it last year. That's all the left needed to doom tens of thousands of people to death.

How would you do that?
It won't treat the inside of a body. Just surfaces where the light hits

For air and surface disinfection.

The FDA, for one reason. UVC radiation can cause severe burns (of the skin) and eye injuries (photokeratitis)

"Risks: UVC lamps used for disinfection purposes may pose potential health and safety risks depending on the UVC wavelength, dose, and duration of radiation exposure. The risk may increase if the unit is not installed properly or used by untrained individuals.

• Direct exposure of skin and eyes to UVC radiation from some UVC lamps may cause painful eye injury and burn-like skin reactions. Never look directly at a UVC lamp source, even briefly. If you have experienced an injury associated with using a UVC lamp, we encourage you to report it to the FDA.
• Some UVC lamps generate ozone. Ozone inhalation can be irritating to the airway.
• UVC can degrade certain materials, such as plastic, polymers, and dyed textile.
• Some UVC lamps contain mercury. Because mercury is toxic even in small amounts, extreme caution is needed in cleaning a lamp that has broken and in disposing of the lamp.

A: UVC lamps are electronic products. The FDA regulates electronic products that emit radiation (both non-medical and medical products) through the Electronic Product Radiation Control Provisions, which were originally enacted as the Radiation Control for Health and Safety Act. Certain electronic products may also be regulated as medical devices. The FDA is responsible for regulating firms who manufacture, repackage, relabel, and/or import medical devices sold in the United States.

UVC lamp manufacturers are responsible for compliance with all applicable regulatory requirements, including Title 21 Code of Federal Regulations (CFR) Parts 1000 through 1004, and section 1005.25 and, as applicable, 21 CFR Chapter I, Subchapter H. The radiological health regulations include reporting of Accidental Radiation Occurrences, notification to the FDA and customers of radiation safety defects, and designation of a U.S. agent for imported lamps. When a UVC lamp is regulated only as an electronic product, there are currently no specific FDA performance standards that apply.

Ultraviolet lamps intended for medical purposes, such as products that disinfect other medical devices or irradiate part of the human body, that meet the definition of medical device under section 201(h) of the Federal Food, Drug, and Cosmetic Act also typically require FDA clearance, approval, or authorization prior to marketing."

This is not convincing. Firstly, the category of safe lamps can be distinguished, and secondly, this can be done during breaks and at night when there are no people

Some UVC lamps contain mercury

By the way, it is also used in conventional household fluorescent and arc-discharge lamps.
