Radium Isotope Tungsten Radiation Shielding

What is Radium Isotope Radiation?

Radium is a chemical element with symbol Ra and atomic number 88, also known as the alkaline earth metals. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays in to radon gas. When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.

The Applications of Radium Isotope Tungsten Radiation Shielding

Tungsten alloy is the best choice for radium isotope radiation shielding. Radium isotope tungsten radiation shielding can be used to hold radium isotope, which is the main component in cancer treatment devices or industrial radiography devices. Radium is a radiation source for cancer treatment. Small seeds are implanted in tumors to kill cancerous cells. Radium isotope tungsten radiation shielding is used in some industrial radiography devices, a technology similar to x-ray imaging used in industry to inspect for flaws in metal parts. When radium is mixed with beryllium it becomes a good source of neutrons, useful in well logging devices and research. Radium also has been added to the tips of lightening rods, improving their effectiveness by ionizing the air around it.

Why Use Radium Isotope Tungsten Radiation Shielding?

Compared to traditional materials such as lead and boron carbide, tungsten shielding provides excellent density with small capacity. At the same weights high density tungsten 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 shielding could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten shielding is suitable for radium isotope radiation shielding.

During design of shielding, tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
Formula: K=e0.693 d / △1/2
K: Shield weakened multiple
△ 1/2: The tungsten alloy radiation shielding material of the half-value layer values
