Traditionally, lead has been the product of choice for radiation shielding. Tungsten shielding blanket has the ability to field-fit, providing for attenuation of radiation totaling from 5 to 10 person-Rem/years than provided by the equivalent weight of traditional lead blanket. And since tungsten is thinner and weighs as much as 50 percent less than lead, it may be more forgiving when workers are performing the physical activities required in a nuclear power plant.

The density of tungsten shielding blanket is similar thickness than lead blankets. And highly flexible and can be molded/formed into any shape. It often competitively priced to lead alternatives. It will engineer and fabricate specialized profiles, slabs and ribbon, including lockable "High Rad" applications.

Here, the method described above has an effect of preventing direct reaction of Ti and WF.sub.6 when an adhesion layer is a laminated layer of Ti/TiN films and a tungsten shielding blanket is formed on the adhesion layer. A direct reaction of Ti and WF.sub.6 will form a solid substrate which will exhibit a volume expansion and become a cause of peeling-off of a layer.

When an adhesion layer for forming a tungsten shielding blanket is formed by sputtering, the substrate is often fixed on a mount using a holder or hooks. At portions under these hooks, a SiO.sub.2 film which is an inter-layer insulating layer is exposed because almost no film is formed under the hooks by sputtering. When a tungsten shielding blanket grows on the exposed SiO.sub.2, the tungsten shielding blanket is easily peeled off because of weak adhesion anti particles are produced.

Mobile radiation is energy traveling through space in the form of waves or particles. Mobile radiation occurs naturally and has always been around, we've evolved with mobile radiation and we're bombarded with it in one form or another every day of our lives - from the earth, from space and even within our own bodies. Some experts suggest a little mobile radiation is a good thing and we all know of its uses in medical science to combat and diagnose some illnesses.

Tungsten alloy mobile radiation shielding is designed for managing large quantities of high-energy radionuclide. A convenient lever allows quick adjustment of window to optimal angle for any user and procedures. A special plate with a hex-shaped recess is mounted on the base to facilitate one-handed loading and unloading of dose pigs incorporating hex-shaped bottoms.

With high density and small volume, tungsten alloy material is now widely used for making tungsten radioactive shielding to protect body from radiation. Tungsten alloy mobile radiation shielding can provide a wide field excellent body protection. Two models are offered with varying sized tungsten alloy products.

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy mobile radiation shielding provide excellent density with small capacity. At the same weights high density alloy can provide the same energy absorption as lead using 1/3 less material. When the weight is certain, more density, and the thickness would be thinner. Tungsten alloy material could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten radioactive shielding is been more and more widely used.

The tungsten alloy crankshaft, commonly called crank, is the part of an engine which has the function of translating reciprocating linear piston motion into rotation with the component of "crank throws" or "crankpins", It typically connects to a flywheel to reduce the pulsation characteristic of the four-stroke cycle, and sometimes there is a tensional or vibration damper at the opposite end for the purpose of reducing the torsion vibrations caused along the length of the crankshaft by the cylinders farthest from the output end acting on the tensional elasticity of the metal. The tungsten alloy crankshaft block is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase.

The application of tungsten alloy crankshaft block is an exercise in compromise. Depending upon the engine’s number of cylinders, crank configuration, and firing order, the mass properties and location of counterweights can vary. Counterweights can balance dynamic loads and couples, tungsten alloy crankshaft block can be used to alter tensional shaft dynamics, and they can be used to reduce main bearing radial and pin bending loads.

With a crank design that has limited throw clearance in the sump, like an F1 engine, using a counterweight material with high density (like tungsten) minimizes the radial space needed for a given counterweight.

From a technical point’s view, no engine regardless of the application can benefit from balancing. As tungsten alloy crankshaft block has high density, so adding tungsten alloy crankshaft balance weight into the racing car has good effected in optimizing the performance of the racing car during the racing progress. Tungsten alloy crankshaft block contributes to the better control of the car's movement.

Tungsten alloy crankshaft block often used to counterweight. The tungsten alloy crankshaft block counterweight means that the sum of all the forces is roughly equal to zero at any point in the assembly's rotation, of which the operation is done by the tungsten alloy crankshaft counterweights. It is critical that the crankshafts must be balanced to customized rod and piston combination.

Tungsten alloy nuclear radiation shielding can be broadly classified into three categories. These three categories are labeled with the first three letters of the Greek alphabet: α(alpha), β (beta) and γ (gamma). Alpha radiation consists of a stream of fast-moving helium nuclei (two protons and two neutrons). As such, an alpha particle is relatively heavy and carries two positive electrical charges. Beta radiation consists of fast-moving electrons or positron (an antimatter electron). A beta particle is much lighter than an alpha, and carries one unit of charge. Gamma radiation consists of photons, which are without mass and carry no charge. X-rays are also photons, but carry less energy than gammas. Some materials absorb beta rays. You can measure this absorption by fixing beta source and a radiation monitor so their positions do not change.

Tungsten heavy alloy has high absorption rate on X rays and gamma rays. Tungsten is 60% better than lead in shielding against X rays and gamma radiation therefore; it can be significantly reduced in size.

Tungsten alloy nuclear radiation shielding also has another characteristic, very high melting point. By this, tungsten alloy nuclear radiation shielding can be used in high temperature which can not be used with lead, for example nuclear scrap container.

Due to its unique characteristics, people use tungsten alloy nuclear radiation shielding in medicine, Tungsten alloy nuclear radiation shielding, such as collimator, tungsten alloy nuclear radiation shielding, beamline, PET syringe shield, vial shield, tungsten alloy nuclear radiation shielding is used to protect workers from the radioactive sources of the scanner used in security and aerodrome, coach stop, etc. Tungsten alloy nuclear radiation shielding is also used in the equipment of industrial radiography, pipe-line inspection (collimator or tungsten alloy nuclear radiation shielding).
