• Deadly Dental Death Ray Box Warning

[quote=BBC News]Dentists have been warned against using a hand-held X-ray machine on patients as it poses a significant health risk. The cheap imported machine, known as the Tianjie Dental Falcon, exposes users and patients to 10 times the normal level of radiation, increasing their risks of cancer and organ damage. The Medicines and Healthcare Regulatory Agency is asking NHS and private dentists to dispose of these devices. It is not known how many patients may have been put at risk. So far, 13 of the machines - sold on internet sites including eBay by a Chinese manufacturer - have been seized at a distribution centre. At least one dental surgery has been found using the device. [B]Emergency testing of the product by the Health Protection Agency and scientists at King's College Hospital in London revealed that it has insufficient lead shielding inside it to protect dentists and patients from excessive radiation. The machine's X-ray beam is also too wide, which means a patient's whole skull and brain is exposed to radiation rather than just their mouth. And the device poses an electrical hazard because it comes with a European plug and a travel adapter that are not earthed or fused for the UK mains supply. As well as being a fire hazard, it could cause a serious electric shock (50,000 volts) to the dentist or patients. [/B] Scientist Donald Emerton, who tested the device, said: "Over time someone operating this machine, such as a dental assistant, would be exposed to unacceptable levels of accumulated radiation and this would have an increased risk to their health. I certainly wouldn't want someone to use this piece of equipment to take an X-ray of me." The MHRA believes it has shut down the UK's only distributor but says investigations are ongoing to ensure no more can be sold and used here. The problem first came to light in June 2012. It is not yet known how many of the devices are already in circulation. The manufacturer - Zhengzhou Tianjie Electronic Equipment Co - is currently unavailable to contact. The Tianjie Dental Falcon was priced at about £200, a fraction of the cost of other dental hand-held X-ray sets available for sale in the UK, which can be over £4,000. Bruce Petrie, of the MHRA's Medical Devices Enforcement Team, said: "It's vital that dentists and dental staff do not buy these dental X-ray machines from eBay or other websites because they are not approved and not safe for dentists or patients. "We are working with eBay and other governments to ensure dentists and patients are protected." He said anyone who had bought one of these machines should the MHRA's hotline on 020 3080 6701 or at [EMAIL="counterfeit@mhra.gsi.gov.uk"]counterfeit@mhra.gsi.gov.uk[/EMAIL]. Barry Cockcroft, chief dental officer for England said: "It is vitally important that when buying equipment, dentists make sure it is appropriate and safe for use. I would urge all dental professionals to be cautious of seemingly cheap devices which may not be fit for purpose and potentially dangerous." Richard Paynter, deputy director of the Health Protection Agency's Centre for Radiation, Chemical and Environmental Hazards, said: "We're delighted that MHRA is now taking such positive steps to ensure public and occupational protection from unnecessary radiation exposure."[/quote] [URL="http://www.bbc.co.uk/news/health-20579318"]Source[/URL] Sometimes it doesn't pay to buy cheap.
What shitty x-ray kills the patient
I want to buy one so i can take x-ray photographs of things.
[QUOTE=Andokool12;38691494]What shitty x-ray kills the patient[/QUOTE] Ones made in China cheaply and sold on eBay. You know, eBay the reputable site for purchasing medical systems.

I just had my mouth x-rayed 7 hours ago. Are you fucking serious. But the machine they used on me looked WAY more sophisticated than that crap.
What kind of fucktarded dentist would buy an x-ray machine [I]from China off of eBay[/I]? One that deserves to lose his license.
Remember, if the ionising X-rays don't give you cancer, the shitty electrics will electrocute you instead! :v:
[QUOTE=Andokool12;38691494]What shitty x-ray kills the patient[/QUOTE] This one, apparently.
[QUOTE=Forumaster;38692114]What kind of fucktarded dentist would buy an x-ray machine [I]from China off of eBay[/I]? One that deserves to lose his license.[/QUOTE] well hey, depending on who it's made by, you can get pretty high quality chinese-made stuff also it's not impossible to find high quality equipment on ebay still, this is just silly [editline]3rd December 2012[/editline] [QUOTE=errington07;38691960][url]http://en.wikipedia.org/wiki/Therac-25[/url][/QUOTE] oh god, i remember having to research this for a uni course - the original reports describing what the patients felt during the procedures and what subsequently happened to them are fucking horrific
Heh never seen anything like that. The ones I've had used on me the dentist have left the room cause its automated
It's like those cheap knockoff superhero toys, except lethal.
I guess Pox is running out of idea's
[QUOTE=Camundongo;38692248]Remember, if the ionising X-rays don't give you cancer, the shitty electrics will electrocute you instead! :v:[/QUOTE] This was the best bit in the newspaper article I read about it earlier, it pretty much warned that they were so badly made inside the person using it might get an electric shock from it.
I'm going to need to buy one of these for experiments.

[QUOTE=errington07;38691960][url]http://en.wikipedia.org/wiki/Therac-25[/url][/QUOTE] Fuck. That. That is the scariest machine I've read about in a long time. That story about that guy that was in the room with the therapy still going on and wasn't able to get out in time creeped the shit out of me.

That story about that guy that was in the room with the therapy still going on and wasn't able to get out in time creeped the shit out of me.[/QUOTE] what really gets me is that the software for the machines was written by just one guy, and any error checking was also done by the same guy at the same time, they decided to remove a few hardware-based safety features that the older Therac machines had because they just thought "hey, we can do ALL of that in software!" even just writing it out, it sounds like a [I]fucking awful[/I] idea [editline]4th December 2012[/editline] i mean, on the mechanical and electrical engineering side of building something like that, the designs would be verified and checked by a few people, so in the context of that, you'd think that at least someone would have the sense to suggest that maybe the same should be done with the software that controls the whole thing
