Dealing with highly infectious diseases like Ebola is often like a logic problem. Disinfecting rooms is hard enough, but what about protective suits? True, they greatly reduce the chances of infection, but getting them off can bring the risk straight back again if the suit isn't decontaminated first. Texas-based Xenex has created protocols that conform to those of the US Centers for Disease Control and Prevention (CDC) for its a line of robots that use UV lamps that to decontaminate hospital rooms and protective clothing exposed to the Ebola virus, so they can be safely removed.

Xenex robots use the company’s Full Spectrum ultraviolet radiation system to disinfect areas and protective clothing before workers remove them, which greatly reduces the chance of infection from handling the outside of the suits and gloves. According to Xenex, its robots are more effective than conventional mercury UV lamps, can disinfect an area in five to ten minutes, are easily integrated into existing hospital procedures, and protective garments can be disinfected and made safe to remove in five minutes. Not to mention that using robots for the task means fewer people are exposed to the danger.

The system uses a high-intensity xenon UV lamp that pulses in the ultraviolet C band covering 200 to 280 nanometers twice a second, as opposed to a mercury lamp’s 258 nanometers. This broad waveband penetrates the microbe’s cell walls and fuse its DNA, rendering it incapable of reproduction. The company claims that the rays can destroy not only the Ebola virus, but also Clostridium difficile (C.diff), Methicillin-resistant Staphylococcus aureus (MRSA), Enterovirus D68, VRE, and other bacteria, viruses, molds, fungi, and spores. The company says that it is as effective as chemical disinfectants, but without the toxic side effects.

"Hospitals across the country may handle suspected Ebola cases so it’s critical for every facility to have a comprehensive plan in place to ensure the safety of healthcare workers, patients and the general public," says Dr. Mark Stibich, co-founder and Chief Scientific Officer of Xenex. "We created this Ebola protocol using our experience in over 250 hospitals, as well as laboratory data on the effectiveness of Xenex’s germ-zapping robots on Ebola-type viruses. Patients, communities, and hospital employees want reassurance their hospital is utilizing the most advanced technology available to protect them."

Very good for while the garment is being warn but once it is removed X-ray the hell out of it.
@slowburn - why not just burn it? Dump it in an incinerator. You get disposable gowns easily. And even if they are made of cotton that's pretty cheap.

Interesting, . . . the information at the website and video states that no one should be in the room when it is operating and it even has a motion detector to turn the robot off if motion detected.
@ sidmehta They appear to be plastic and I don't like disposable especially in the third world. For the record X-rays and Gamma-rays are the same frequency so you can sterilize with tube generated X-rays.

How about having them first take shower with the protective suits on. And then zap with UV?
Industrial UV systems for curing ink and purifying water can quickly blind people so I am surprised they show someone looking at the light.
Does the face shield filter out the UV?
Bio-hazard suits can be very dangerous to remove. How do you ensure that you have covered the entire surface of the suit and that there were no folds or material covering other surfaces?
Are or can the suits be designed to be transparent to the UV? Would you then wear a layer underneath the suit that blocks the UV from impinging the wearers skin?
Likewise, does the room have to be designed so it can be decontaminated by light. Bugs can go where the light doesn't shine.

You can easily destroy Ebola using 1.2 million rads of Gamma radiation. This is the same radiation level as exists at the core of an operating nuclear reactor. Just pop your subject in there for a quick detox and bingo bango you're done with your task.
It is very cool that a new technology like this is being used to improve health. Something like this is something you think of being in a Sci-Fi movie. Hopefully these robots catch on and their germ killing light can be used in hospitals a cross the country.
