The tungsten generator shields contain a radioactive core loaded with an isotope called molybdenum 99, which decays to a daughter isotope, technetium 99m. This radioactive fluid is collected and diluted with sodium chloride, mixed with a range of diagnostic agents, and injected into patients. The radioactive substance collects in certain parts of the body and can be viewed by a gamma camera. The parent molybdenum 99 has a 2.75-day half-life, while the daughter isotope has a half-life of only 6 hours, minimizing its time in the body.

Supplied with knurled and brass-threaded closures, leaded glass viewing windows, and our ergonomic non-slip finish, these tungsten generator shields provide the optimum solution for “milking” your generators.

X-ray computed radiography (CR) is kind of digital imaging technology using tungsten alloy imaging plate (IP) as carrier for X-ray image. The most important characteristic of CR system is that it is made of tungsten alloy IP, the new generation for X-ray image which is different from film, carrier utilized by traditional shadowgrap. The new carrier has high sensitivity and latitude to X-ray.

But tungsten alloy IP cannot produce visible light directly after absorbing X-ray. It produces stable sub-image and store inside crystal of tungsten alloy IP after collecting analog signal of X-ray. Sub-image can be read when being scanned by photoluminescence. Conversion of signal output by tungsten alloy IP is finished. Then signal forms digital image after being dealt with by computer. The final image can be shown on fluorescent screen or printed on film, heat sensitive paper or others, besides storing in disc and system.

Focusing ring used to adjust the lens so that the subject appears sharp on the film or CCD. Most cameras now have automatic focus (AF), some have manual focus override (MF) and some have a fixed focus (F) lens that ensures things from about 1.5 meters to infinity are relatively sharp. A few cameras have a power focus (PF), which is a manual method, using a motorized tungsten alloy radiation focusing ring. Lenses with a ring that allows a good grip make tungsten alloy radiation focusing ring easier to adjust and focus manually.

A low-cost lens doesn't have a tungsten alloy radiation focusing ring. Found in very basic cameras. The lens is set to a distance of around three meters and relies on the depth of field to bring everything from about one and a half meters to infinity. The quality is always a compromise over a lens with adjustable focusing. Tungsten alloy radiation focusing ring is good to our health.

An optical device is built into older cameras or added as an attachment. That is used to work out the subject distance by comparing two viewpoints. You see a double image and adjust the lenses until the images form one which gives a distance reading that can then be transferred to the focusing ring.

As we know, all microelectronic have radiation when we used. In order to resistant radiation from these products, we have to protect measures to prevent it. Tungsten alloys is a best choices for tungsten alloy radiation focusing ring. Compared to traditional radiation shielding materials, tungsten alloy radiation focusing ring provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy reliable radiation focusing ring properties.

To protect our health from the radiation, tungsten X-ray protection apron becomes more and more popular in medical areas. With the development of our daily life, more and more machines are used by people both in medical and other industries which brought much more radiation for us than ever, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. they are very harmful to our body, there also comes a lot of shielding made by tungsten heavy alloy such as tungsten X-ray protection apron from tungsten powder which is very popular in medical especially when the patient makes a panorama X-ray.

Tungsten X-ray protection apron made from tungsten powder equally protects against the radiation, as tungsten powder is high density with small volume, good corrosion resistance, and high temperature resistance, non-toxic and environmentally friendly.

Tungsten alloy barrel weight, is also called tungsten barrel weight is commonly used for fishing jigs and darts where there is a need of high mass in a limited space. Tungsten barrel weight resembles a bullet. Cylindrical in shape, tungsten alloy barrel weight is narrower at one end and widen out at the base.

It is difficult to find out what tungsten alloy barrel weight means in English, because both the weight for fishing and for darts are called tungsten alloy barrel weight. Besides, in Chinese,barrel means container used for stocking, but in the foreign countries, barrel is the object with barrel shape.

It is possible to use an alternative type of radiotherapy, which is known as afterloading (a version of brachytherapy) when it is difficult to access the diseased cells directly. Tungsten alloy brachytherapy shielding consists of implanting a radioactive seed inside the patient's body, via a catheter. Before and after treatment the seed is kept in a large tungsten safe, tungsten alloy radiation shielding is used to protect the patient and medical staff against radiation in the treatment.

Before and after treatment the seed is kept in a large tungsten safe, to protect the patient and medical staff against radiation.

Tungsten alloy brachytherapy shielding is an integral part of the treatment regimen for cervical cancer and, generally, outcome in terms of local disease control and complications is a function of dose to the disease bed and critical structures, respectively. Therefore, it is paramount to accurately determine the dose given via brachytherapy to the tumor bed as well as critical structures.

Tungsten heavy alloy is ideal for shielding against radiation. The very high density of tungsten alloy shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics.

Tungsten heavy alloy stopper shields 50cm thick (concrete brick) around the 288cm tungsten alloy stopper shields. Concrete tungsten heavy alloy stopper shields before and after tungsten alloy stopper shields to stop the particles having interacted at or before the tungsten alloy stopper shields.

Tungsten heavy alloy stopper shields are usually made of concrete 50cm thick, with an inner aperture of 110cm and an outer aperture of 160 cm the all length of the beam stopper. It leaves a layer of air of 15cm around the tungsten heavy alloy stopper shield.

Tungsten heavy alloy stopper shields have been chosen instead of iron. Both material have a similar dE/dx (iron has even slightly higher one); therefore the particle absorption is twice the absorption in iron.

The density of tungsten heavy alloy makes it the first choice for radiation shielding applications in the medical imaging and treatment industry. Tungsten heavy alloy is the inert alternative to materials such as lead and depleted uranium, making it safe for use even in the most environmentally sensitive areas.

The tungsten alloy radiation shielding door is filled with special shielding materials in order to protect devices and human beings from invisible radioactive rays, electromagnetic waves, and magnetic fields. Depending on the purpose of use, the tungsten alloy radiation shielding door is categorized into tungsten alloy radiation shielding doors installed in X-ray rooms, nuclear medicine rooms, RI(Radioactive Isotope) laboratories or the radioactivity control rooms of industrial facilities, and electromagnetic wave shielding doors installed at magnetic wave shielding compartments protecting medical instruments in hospitals or MRI rooms.

The tungsten alloy radiation shielding door is applied in facilities like Linear Accelerators or places that handle Radioactive Isotopes such as nuclear power plants, medical facilities or institutions. Shielding Effectiveness(SE) is calculated in such a way that the radiation dose is less than the legal dose limit and then the proper amount of tungsten alloy radiation shielding door materials is filled inside the door in order to minimized bombing damages caused by radioactivity.
