Tungsten alloy –more healthy materials for radiation protection 2012-12-28

Instead of the Lead, the Tungsten alloy would provide reliably shields against X-rays and gamma radiation in more healthy way. CISRI has made various shielding components with Tungsten alloy to protect people against radiation effective.
Whether in the world of medical or industrial X-ray technology, radiotherapy or nuclear power stations: Wherever high-energy radiation is used, it is vital to protect people against it.
The denser the material, the better able it is to protect from radiation. That is why heavy elements absorb X-rays and gamma radiation particularly well. Lead is still the most frequently used shielding material, but Lead is a toxic material that is harmful to the environment and humans. The onerous recycling process makes Lead expensive despite the low initial procurement costs. Many enterprises are therefore looking for a suitable alternative for providing reliable radiation protection.
The density of tungsten is 60 percent higher than that of lead. That is why even thinner layers of tungsten are able to provide reliable shielding against radiation. CISRI tungsten alloy consists of tungsten and a small proportion of nickel-iron. Like tungsten, the material has excellent shielding properties. However, it is also considerably more ductile than tungsten and can therefore be machined better.
However, it is not just in shielding applications that represents a better alternative than lead. When used in collimators, it reduces scattered radiation in the detectors. When used for balancing weights and vibration dampers in motors and drive components, this tungsten alloy is able to withstand extreme stresses.

Besides supplies tungsten alloy, CISRI also supplies pure Tungsten, pure Molybdenum, pure Rhenium , Tungsten-Rhenium alloy, Molybdenum-Rhenium alloy and Tungsten-Rhenium thermocouple wire.
