When checked, Shutterstock's safe search screens restricted content and excludes it from your search results. Hard X-rays can penetrate solid objects, and their largest use is to take images of the inside of objects in diagnostic radiography and crystallography. The roentgen (R) is an obsolete traditional unit of exposure, which represented the amount of radiation required to create one electrostatic unit of charge of each polarity in one cubic centimeter of dry air. The rad is the (obsolete) corresponding traditional unit, equal to 10 millijoules of energy deposited per kilogram.
The sievert (Sv) is the SI unit of equivalent dose, which for X-rays is numerically equal to the gray (Gy). X-rays are generated by an X-ray tube, a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity. In crystallography, a copper target is most common, with cobalt often being used when fluorescence from iron content in the sample might otherwise present a problem.
X-ray fluorescence: If the electron has enough energy it can knock an orbital electron out of the inner electron shell of a metal atom, and as a result electrons from higher energy levels then fill up the vacancy and X-ray photons are emitted. So the resulting output of a tube consists of a continuous bremsstrahlung spectrum falling off to zero at the tube voltage, plus several spikes at the characteristic lines.
In medical diagnostic applications, the low energy (soft) X-rays are unwanted, since they are totally absorbed by the body, increasing the dose. To generate an image of the cardiovascular system, including the arteries and veins (angiography) an initial image is taken of the anatomical region of interest. A specialized source of X-rays which is becoming widely used in research is synchrotron radiation, which is generated by particle accelerators. The most commonly known methods are photographic plates, photographic film in cassettes, and rare earth screens.
Before the advent of the digital computer and before invention of digital imaging, photographic plates were used to produce most radiographic images.
Since photographic plates are sensitive to X-rays, they provide a means of recording the image, but they also required much X-ray exposure (to the patient), hence intensifying screens were devised. Areas where the X-rays strike darken when developed, causing bones to appear lighter than the surrounding soft tissue. Contrast compounds containing barium or iodine, which are radiopaque, can be ingested in the gastrointestinal tract (barium) or injected in the artery or veins to highlight these vessels. An increasingly common method is the use of photostimulated luminescence (PSL), pioneered by Fuji in the 1980s. The PSP plate can be reused, and existing X-ray equipment requires no modification to use them.
For many applications, counters are not sealed but are constantly fed with purified gas, thus reducing problems of contamination or gas aging. Some materials such as sodium iodide (NaI) can "convert" an X-ray photon to a visible photon; an electronic detector can be built by adding a photomultiplier. The Berg Play and Study Center truly is an innovative design, well suited for both younger children and teenagers. Design -- creative environment in childhood leads to success in later life -- there is many a research study that supports this claim. Storage -- one of the stronger points of the Play and Study series; when it comes to storage, perhaps only the Berg Sierra collection offers more. Computer Desk -- this system comes complete with a full sized desk which features 6 drawers and is perfect for studying and doing homework.


Sturdiness -- kids like to play, and in their play they often get carried away and subject the furniture to stresses considerably surpassing those which come from normal use. However, material is only a part of what makes any structure sturdy; design is equally as important and Berg's products, with their wide boards and surfaces and fortress-like built-in chests, stairs and desks make for compact, heavy and, well, sturdy formations. Made in the USA -- yes, we have mentioned it before, but it doesn't hurt to do it again as it's not unimportant. All products from Berg's Play and Study collection are available in five different finishes, which makes them a good fit for the majority of surroundings. You can further personalize the appearance of Berg bunk beds by picking one of the various knob colors available.
Accent colors provide an additional way to enliven the appearance of Berg's Play and Study loft beds. Attractive design -- Berg Furniture makes good looking products, there is hardly any question about that, and the user base concurs unanimously.
Durability -- if it's to believe the actual users, Berg produces some super sturdy and durable furniture. If you're looking for an Ashley Furniture desk then perhaps an Ashley executive desk, an Ashley Drake desk, an Ashley Winslow desk or an Ashley writing desk would be something that could be of interest. This process produces an emission spectrum of X-ray frequencies, sometimes referred to as the spectral lines. The intensity of the X-rays increases linearly with decreasing frequency, from zero at the energy of the incident electrons, the voltage on the X-ray tube. A second image is then taken of the same region after iodinated contrast material has been injected into the blood vessels within this area. The contrast compounds have high atomic numbered elements in them that (like bone) essentially block the X-rays and hence the once hollow organ or vessel can be more readily seen.
In modern hospitals a photostimulable phosphor plate (PSP plate) is used in place of the photographic plate.
The system maximizes function using minimum floor space, combining fun and practicality all in one piece. The stairs have broad, generous stepping surfaces with non-slid treads plus a handrail, all of which allows for a comfortable and safe access to the top bed. In addition to the already mentioned staircase drawers, the Play and Study units also feature six large desk drawers, plus a pencil drawer. The desk is computer ready, with space for a computer tower to the side, a pull out keyboard, a surge protection unit and a phone jack.
Buying US made products keeps American workers employed; working people pay taxes and contribute to the social security system and have money to spend which helps invigorate the economy and strengthen America as a nation -- all this is especially beneficial to the middle class.
We haven't been able to find enough user comments on the Play and Study collection to be able to form a valid assessment on it, but there is plenty of buyer accounts on other Berg bunk beds and we can probably safely assume that those findings apply to this collection as well. In fact, many buyers assert that the staircase played a crucial role in their decision to get a Berg product. Not surprising, considering the wide surfaces and fortress-like appearance of their formations. There are some grievances about the cost; mostly, buyers complain they were enticed into spending more than they intended. They are also a bit pricier than your average bunk bed, but if you can afford one, they do come highly recommended.
Over at this store you have a very wide array of options to choose between so it doesn't matter whether you prefer something traditional or something more modern in design: they have it all. The spectral lines generated depend on the target (anode) element used and thus are called characteristic lines. These two images are then digitally subtracted, leaving an image of only the iodinated contrast outlining the blood vessels.


Photographic film largely replaced these plates, and it was used in X-ray laboratories to produce medical images. In the pursuit of a non-toxic contrast material, many types of high atomic number elements were evaluated.
After the plate is X-rayed, excited electrons in the phosphor material remain "trapped" in "colour centres" in the crystal lattice until stimulated by a laser beam passed over the plate surface. Electrons accelerate toward the anode, in the process causing further ionization along their trajectory. The Play and Study units all come with a loft-style twin-size bed, a full size student desk, a small built-in play area and tons of storage. On top of that, there is plenty of shelf space for books, computer supplies etc plus various nooks and crannies for the paraphernalia kids like to collect.
Furthermore, American products are manufactured to meet a code of standards; these regulations are designed to keep the consumer safe and provide the high level of quality that shoppers rightfully expect. They tout stairs as a safe alternative to beds with ladders; proclaim the stairs are very safe for the young ones that have to get up and down in the middle of the night -- in short, the staircase is viewed as a major safety feature. A few reviewers expressed a disappointment with Berg's choice of material, due to their belief that engineered wood was inferior to solid wood.
Desk is modular and is able to be disassembled into three major parts which makes it easier to move.
The radiologist or surgeon then compares the image obtained to normal anatomical images to determine if there is any damage or blockage of the vessel. In more recent years, computerized and digital radiography has been replacing photographic film in medical and dental applications, though film technology remains in widespread use in industrial radiography processes (e.g.
For example, the first time the forefathers used contrast it was chalk, and was used on a cadaver's vessels.
This process, known as a Townsend avalanche, is detected as a sudden current, called a "count" or "event". Note that Berg devotes a special care to drawer construction, which results in solid, spacious boxes sporting a finish that is both durable and easy to clean. Some go a bit further to attest that the construction stands up to abuse given by their children, and even testify that it has proven to be very sturdy over the years. Difficulties in changing sheets also get mentioned from time to time, and an occasional buyer finds fault in Berg's products' weight and unwieldiness. When the film is developed, the parts of the image corresponding to higher X-ray exposure are dark, leaving a white shadow of bones on the film. The drawer slides are of heavy caliber metal, robust and reliable, with a mechanism preventing the drawers to fall out when fully extended.
Photographic plates are mostly things of history, and their replacement, the "intensifying screen", is also fading into history.
The metal silver (formerly necessary to the radiographic & photographic industries) is a non-renewable resource. Thus it is beneficial that this is now being replaced by digital (DR) and computed (CR) technology.
Where photographic films required wet processing facilities, these new technologies do not. With the ample space and storage compartments, this roll top desk is perfect for any home office. With the diamond in a starburst inlay and the unique shaped styling, this furniture radiates with sophisticated style.
