Tungsten Alloy Magnetic Radiation Shielding

Tungsten magnetic radiation shielding of 70 mm dia. is usually used for radiation protection.

Density: 18-18.5 gms/cc

Tungsten Alloy Radiation Protection System

Tungsten alloy radiation protection system is a patented totally encapsulated shielding system. It’s unique formulation gives flexible shielding in inaccessible and restricted applications where traditional methods of shielding are difficult to provide, which is available in flat sheets of special sizes and guide tube shields of standard and custom lengths.

Tungsten Alloy Shielding is Better Than Lead

Tungsten alloy shielding is more an more popular for radiation protection. Generally speaking, the absorption rate of X-rays and gamma radiation is directly proportional to the density of the shielding material, as tungsten alloy has a high density but small capacity, tungsten is a suitable for radiation shielding. Since tungsten alloy is denser than lead, these alloy can be up to one and a half times more effective than lead, and provide extremely efficient protection from radiation sources, especially in applications where space is limited.

What Are the Different Types of Radiation Shielding?

Radiation shielding is the use of materials or devices to protect against ionizing radiation. Radiation occurs when energy is emitted from one substance and travels out in straight waves, possibly penetrating another substance. When this energy is absorbed, it can have the effect of exciting or destabilizing atoms. If a certain radiation penetrates an animal, it can have harmful impacts on the body, sometimes causing cancer or deformities. Shielding uses specific types of material, such as a leaded glass pane, a lead apron, or packed dirt, to act as a barrier between the body and the source of radiation.

However, compared with other materials, tungsten alloy material is the most suitable for radiation protection.As tungsten alloy is the right material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead and steel), simplified life cycle and high strength.

Radiation Protection Door

Chinatungsten innovative radiation shielding system is the keystone of radiation shielding product line and provides superior neutron, photon and proton attenuation. When combined with state-of-the-art shield technique, radiation protection doors could be provided. Chinatungsten can provide a treatment center which far exceeds the features and performance of concrete constructed facilities.

Choice of Radiation Shielding Instruments

While the community is responsible for establishing uniform rules in the radiation protection field in order to achieve a high level of health protection of workers and the general public, it falls on to transpose into their national legislation such rules and to implement them.

A directive is therefore best suited to create a common approach on defining requirements for radioactivity parameters for monitoring the quality of water intended for human consumption in the light of scientific and technical progress.

As a consequence, harm onised requirements for the protection of the health of the general public with regard to radioactive substance in water intended for human consumption are defined.
