help police save lives as well as help stem the flow of dangerous materials. for the handheld detector to check for explosives drugs and other chemicals in the air. professional equipment. is expensive. is simply to get such machinery out into the field. as a result. technology. evil doers. sniffer dogs have been used for this purpose for a long time now. they're great at explosives or drugs detection but they have one major disadvantage a dog is really only able to work a maximum of thirty minutes before needing
a rest they can resume work only after six to eight hours with a dog isn't able to tell you the exact kind of substance it's found it can only signal that something is there by raising a poor or giving some other sign but then it's up to the explosives team to figure it very often putting their own lives at risk to do so also every dog is different simply might not be to work in contrast detectors will work exactly the same as all the others. according to the developers. apart from their competitors is the simplicity of operation and its ability to identify even traces. tissues. detector weighs in at about three kilos and much of that comes from the battery pack. for potentially dangerous particles. which is done by way of the discharge in the connect.
by knowing how. to pass a fixed distance. field the spectrometers can identify what's in the air around us this is. a database of known compounds the ones in the system so far have been selected for their usefulness in the field of both the programmers here and. can add to recognizable compounds as needed. spectrometers exist many of those have one significant drawback. traditionally these devices have radioactive substances. same principle in mind but then thought. and eventually we decided to use.
any kind of substance actually we didn't invent it we just made it so now it's a portable device and added new functionality to enable operators to use it effectively and the failed. so far these developers have delivered more than two hundred of their cattle. at the moment they're under. cation with russia's interior ministry if they get the all clear orders from the country's biggest security agencies. the potential terrorists only think we ought to worry about but in reality the most dangerous things might be hiding in the. mind we've come to this region to take a closer look at the make up of things not. here at the. state physics scientists have developed a compact. technology hoped would help us get. the bottom of some of the longest
running defeats regarding popular soda brands have got to admit that i had delusions of unlocking secret recipes and discovering reported ingredients to my apparently untrained mind it seemed as if the roman spectroscope developed here was the best way to get the answers that we were looking for. now in theory there's a wide array of potential methods of analysis each possessing its own benefits and shortcomings for example liquid and gas chromatograph are exceptionally precise. and expensive then there's mass spectrometry which also carries a pretty hefty price tag infrared spectrum scopes can be less expensive but demand a complex sample prep work and excludes gas samples then there are traditional chemical analyses applications of which are more limited and require extensive training in many cases though spectroscopy is the best just not for investigating dark colored sodas. contains
a coloring agent whose luminescence spectrum is too intense for us to observe any individual molecule vibrations that we would usually need to register in order to identify the composition of the substance in question in short the spectrum of the coloring agent makes it impossible to observe any spectra of the combinational scattering which would be otherwise visible. but just because our idea was less than successful doesn't mean that the inspector are five thirty two as it's called on the market can't perform a litany of other tests to help massage my wounded pride show that a soda free from colorings heals the results we were looking for the three main peaks correspond to water sugar and acid thank you. well this is the voice can be used for nonscientific purposes that is for practical tasks as for example in the analysis of gemstones it's always interesting to know what impurities the gemstone has because they help us to find out more about the stone itself like to identify
its origin. it sheaves this by creating and investigating what's called the roman scattering when a correctly tuned a laser beam hits the molecules they become excited and begin to vibrate that scatters or refracts the laser light had a slightly altered wavelength the device is internal c.c.d. sensor measures the shift of the wavelength those alterations are then compared against the system's database of rom and shifts in terms of gyms it allows anyone operating the inspector five thirty two to tell if they're looking at a fake or something much more precious. one of the achievements we take pride in is the high spatial resolution of devices . this becomes especially apparent when the device is attached to a microscope. with a resolution of around one micro meter you can obtain an individual ion spectrum every square my current of the surface. this enables us to present
ourselves as a major player on the serious scientific research device market. one of our latest achievements is measuring graphing. only devices such as ours can identify a layer of graphing which is this thin as one atom grows on the substrate material . thank you to. the inspector team manages all this by employing a thirty make laser that emits a five hundred thirty two meter wavelength the c.c.d. sensor is designed to work at room temperature and has been specially designed to suppress other physical processes like raleigh scatter. they can interfere. that means the resulting analysis is just as accurate as anything else out there on the market and does it in a matter of seconds and it's automatic recognition software alerts us to what's right in front of our noses but a knowable without specialized equipment even it places
a. patriarch's pond there hidden dangers all around and the first set to protecting yourself is knowing the potential risks. to the plane. particles everywhere they come from the sun. naturally occurring objects to drive the point home. showed elevated radioactivity from a simple. we can measure the radiation background radiation is pretty low ciro point zero eight but it will gradually go up. that extremely compact. was spurred on by the nuclear disaster in fukushima japan while the immediate threats to those in the vicinity were clear right away the experience has left many people concerned about extraordinary and every day radiation. looking for a way to give people more peace of mind this moscow based innovator to work
designing his own smartphone powered. the device can help people better understand the risks that simply aren't visible for example the paint used in. particles that are easily measurable but the right equipment. right now we already have a whole line of software products and devices for various smartphones. cell phones laptops books all with varying levels of complexity on the market from simpler and less expensive models to more sophisticated versions of the. but of course the idea of checking radiation levels is far from a new one ever since people understood the risk of radioactivity there's been the trusty but often cumbersome a geiger counter to measure it the device is characteristic clicking sound has long let the user know if the plate of food in front of him or her is safe to eat each
audible click is an incoming radioactive particle being ionized since its introduction models have become more portable is simply taking that tradition into the future in the. next version of our meter. which we're calling conductor version. we're also working on a totally new generation of the device which will employ a grapheme based sensor. at the moment though those plans are just that plans on paper to make the technological leap the company needs new investments which could be coming in the very near future at the end of january the company expects to hear back from about a sizable grant that could give them the resources they need to move those next generation radiation detectors from paper to the production line. the companies anxious to get that going because according to certain estimations there could be a major so. we can see fairly high demand across the
world. especially in southeast asia and japan recently we ordered a marketing research report from a japanese company basically based on very calculations they believe that if these devices were launched on the japanese market today in the first month we would sell around forty to fifty thousand of them and over the course of a year sales would total some five hundred thousand. from that point the market would stabilize and show its true capacity. overall. the japanese market is. ready to accept some three to six million devices per year. well annual global demand. and again this is according to the marketing research report would likely be around ten to fifteen million devices. and on them. and as
a wise man once said knowing is half the battle. enables users to note on a unified map where they found increased levels of radiation that could then in theory be used to inform government agencies or interested citizens with a handful of accidents ingrained in our collective memories that information is of concern to people all over the globe presently there are some one hundred seventy five million living within seventy five kilometers of major nuclear reactors of course everyone's hoping for fully safe operations but now your own dosimeter is never more than an arm's length away. you know how sometimes you see a story and it seems so you think you understand it and then you glimpse something else you hear or see some other part of it and realized everything you thought you knew you don't know i'm tom harpur welcome to the big picture.

welcome back to technology update identifying external threats is one thing but no profession is more to gain by piri beneath the surface than medicine with each new advance scientists are leveling the playing field against seemingly unseeable foes since we can really only observe the consequences or symptoms of most illnesses doctors have always had to rely on reading between the lines they can often only narrow in on our ailments by process of elimination but on the back of many giant
leaps forward in the past century m.d.'s now have a greater arsenal at their disposal. for example they can bombard our bodies with harmless alter sonic waves showing the image in real time of their high frequency poses are good for monitoring pregnancies as well as blood flow in their radioactive isotopes which allow doctors to target specific organs often to check for cancer magnetic fields have also been mastered to keep an eye on soft tissues like the brain injured tendons but the granddaddy of them all is the x. ray which has been giving doctors a glimpse into our bones and lungs for more than one hundred years. the technique discovered merely by accident has highlighted how gaining new insight into what was previously out of reach these major dividends the technique revolutionized many diagnosis processes with oversize film images becoming a standard sight in hospitals everywhere but that's all in the past digital is the
name of the game now armed with nearly instantaneous results doctors can see right away if they successfully snap the needed pic properly. more flexible apparat it make modern day technicians work almost as effortless as clicking a mouse. if we compare the latest x. ray equipment with previous models but of course the first big difference is the ability to refine and archive the images digitally. additionally it's increased the quantity as well as the quality of diagnoses we perform. and in russia the first word of x. ray technology is a. health expo in moscow recently they showed off their latest wares they produced a range of high tech equipment all of it focused on getting past the barriers that nature's created. based in st petersburg the company is certainly no newcomer to the russian medical tech scene it was started in the late one nine hundred eighty
s. by a team of engineers responsible for the first camera developed in the soviet union over the years and decades electron has slowly but surely improved and expanded the products it offers to the medical profession by the company's calculations it currently accounts for about twenty five percent of the markets in which it operates. at this point one of its main offerings is an entire set of x. ray machinery for doctors that need to get a peak on the inside accuracy and it's clearly her utmost importance which requires electrons to take certain precautions. so obviously. these are a whole number of test objects that allow us to evaluate various image parameters like this one which shows us the resolution that is the smallest objects you can see in a human body for example this test object is a specially made lead plate and has pairs of lines the different intervals within
the space of one millimeter judging by how many line pairs we see we can figure out what the smallest element we can x. ray in the human body is there are also these objects that have varying densities which we used to conduct contrast sensitivity checks and there exists a great variety of. such tests. in addition to offering traditional simple static snapshots these are equipped with a linear x. ray technology it allows easier scanning of mobility impaired patients and also enables technicians to focus in on one spot in particular by moving the detector along with the x. ray tube linear x. rays minimize background image interference the next generation of technology that's been adopted the world over including a lot of russian hospitals that use it as well is computed tomography it involves scanning the patient's body to produce demographic images or slices of specific areas of the body then these individuals put together and could be looked at from
any number of angles and certain parameters could be measured these cross-sectional images are used for diagnostic and therapeutic purposes so that the doctor can get a full picture of the patient's condition but getting that three d. computed tama graph or c.t. image isn't so easy the circular scan only captures an area about twenty five millimeters wide so if the doc needs to check on a large section of the body it can take dozens of spins around. the world over there are really only a handful of companies that are capable of producing equipment like this given the complexity and cost to develop it it should be no great surprise that here electron has teamed up with philips. this is the first full cycle innovative partnership of its kind in russia and usually the russian side provided some fifteen percent of the components for the
most part this included things like service aleutians and associated software. but today a contribution has risen to thirty percent and we are in the process of increasing it to as much as fifty percent. in other words we're gradually replacing foreign components with russian made ones. to the most. more than five hundred of their kids to hospitals and clinics around the country additionally electronic exports its equipment. only. investigators. some cases. is just what the doctor ordered which takes us to the physical institute in addition to the nuclear physicist peace laureate. researchers that received prizes in physics. just. stretching all
the way back to the days of peter the great moment the hottest topics hollowed halls is work on a revolutionary kind of magnetic resonance imaging machine. much like the computer . scanners. at the structures of. electromagnetic radiation exceptionally powerful magnets to redirect the hydrogen atoms and eventually give a detailed account of the internal. what we do here is considered a priority for the limited physical institute. that is currently the biggest medical project being developed by the russian academy of sciences. actively supported by the ministry of industry and trade. provided a grant to stimulate and implement this projects.
around the human. field makes the hole in. the primary. which eliminates only. a liquid he. doesn't actually get. just. such a construction has numerous advantages the first among them are economic for one thing by cutting pricey helium out of the equation significantly reducing it these images for much cheaper to produce than operate in russia the liquefied gas costs around twenty five dollars per liter which adds seventy five to one hundred
thousand dollars to the initial price what's more. starting to dwindle making them more helium and. then there's the fact that monitoring and maintaining several leaders of super cold liquid helium. and separating the cooling unit from the complex set of other useful benefits this kind of m.r.i. machine is very small and highly compacts you need as little as nine square meters of space to install it's one of the big m.r.i. can take up to forty. the hospitals and clinics this is important as it's difficult to totally reconfigure a mob geria. the institute is currently about halfway to the finish line with these cutting edge. they've already finished. with that feather in their cap. the team's effort has been focused on getting
a full body. scanner ready for production. go as planned they should have completed in about two to three years' time. so the whole team is open your eyes to a world of possibilities once you start looking at first glance but that's all for this revealing edition of technology update we'll see you next time and enjoy the ride.
