Product Description

What is Technetium 99 and Technetium 99m

Technetium 99 (99Tc) is an isotope of technetium that decomposes with a half of the life of 211,000 years as the stable ruthenium 99, throwing out beta particles, but does not emit gamma rays. It is the phenominally long-lasting fission product of uranium fission, creating the largest fraction of the total long-lived radiation emanation of nuclear waste. Technetium 99 embodies a fission product output of 6.0507% for thermal neutron fission of uranium 235.

Technetium 99m (99mTc) is a short-lived (half-life about 6 hours) meta stable nuclear isomer applied in nuclear medicine, created from molybdenum 99. It decomposes by isomeric transition to technetium99, notable properties, since the very long half-life and type of decomposition of technetium 99 puts little further radiation burden on the body.

The Applications of Technetium 99 Tungsten Radiation Shielding

Because of its superior density, optimal absorption characteristic against radiation and eco- friendly attribute, tungsten alloy is extensively used to create Technetium 99 tungsten radiation shielding. Technetium 99 tungsten radiation shielding is mainly applied in nuclear medicine, that as the radiation shielding device or a container for Technetium 99m. Technetium 99m is utilized as a radioactive tracer and detect the body through medical equipment (Gamma Camera). Technetium 99m enables the scanning procedure that gathers data swiftly as well as lowers down radiation exposure to patients. The same features make the isotope befitting only for diagnostic purpose but never for therapeutic application.

The Advantages of Technetium 99 Tungsten Radiation Shielding

Tungsten, that is a sturdy and scarce metal and often available in the form of chemical compound, and plays pivotal role as an effective lead replacement material. Tungsten alloys possess better density and sturdiness, in fact almost 60 % higher than lead, which have notable characteristics for radiation shielding applications.

They can be applied to assuage X-ray and gamma rays. Other advantages of tungsten-based materials encompass their resistivity to high temperature and environmental friendliness.

At the time of designing shielding, tungsten alloy radiation shielding is counted as per the requirements of shield to decrease the multiple thickness of shielding materials.
