As medical science developing so repaid, there is more and more radiation in our life, which has become a new trouble, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. Tungsten alloy radiation cap protect us from the radiation. Tungsten alloy radiation cap is better than shielding made by other materials.

Tungsten alloy radiation cap is ideal product against X rays and gamma radiation. The very high density of tungsten alloy cap allows a reduction in the physical size of shielding cap, without compromising their rigidity or the effectiveness of the tungsten alloy radiation shielding characteristics.

Scientists think that tungsten is much less toxic than lead or mercury. Tungsten has been shown to act by antagonizing the action of the essential trace element, molybdenum. Long industrial experience has indicated no pneumoconiosis to develop among workers exposed solely to W or its insoluble compounds.

In order to protect patients, doctors, nurses and other people who maybe exposed to radiation, sources of the radiation must be safely separated and shielded. It is crucial that holding and delivery instruments for radioactive materials would keep the radiation levels low enough, not to create harmful effects of ionizing radiation such as breast cancer, skin cancer, etc. Lead and steel are the traditional protection materials, but tungsten alloy radiation shielding is without a doubt the best solution. Excellent radiation-absorption, twice the
density of lead and good physical resistance is main reasons to use tungsten alloy radiation shielding. Tungsten alloy health is a hot topic for environment protection and human protection from radiation.

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy radiation shielding provides excellent density with small capacity. With the same weight, high-density alloy can provide the same energy absorption as lead using 1/3 less space.

Tungsten heavy alloy is best choices for tungsten alloy health applications, in both medical and industrial settings. Tungsten alloy radiation shielding provides excellent alternative for traditional radiation shielding materials. High-density tungsten alloy radiation shielding can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy's reliable radiation shielding properties.

The tungsten alloy crankshaft is placed on the balancer and spun to determine the points where metal needs to be added or removed. The balancer indexes of the crank show the exact position and weight to be added or subtracted. The electronic brain inside the balancer head does the calculations and displays the results. The tungsten alloy crankshaft counterweight is done by two inserts which are made of tungsten alloy, to improve acceleration. Common method is adding light elements such as silicon to reduce the weight of the crankshaft.

Tungsten alloy crankshaft brick typically connects to a flywheel, to reduce the pulsation characteristic of the four-stroke cycle, and sometimes a tensional or vibration damper at the opposite end, to reduce the torsion vibrations often caused along the length of the tungsten alloy crankshaft brick by the cylinders farthest from the output end acting on the tensional elasticity of the metal.

Using tungsten alloy crankshaft brick can also be cost effective with some crankshaft designs. Since the raw steel stock needed for the crankshaft can be much smaller if it does not need to include the counterweights. It also makes it easier to machine the crank pins hollow without having counterweights in the way.

With regards to tungsten’s properties, it is a very dense metal with a high Moe, so it makes a more compact counterweight mass. If the tungsten alloy crankshaft brick counterweights are radically bolted, fatigue is not much of a problem since the bolt loads are not reversing.

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.
