Tungsten Generator Shields

tungsten generator shieldsTungsten generator shields contains 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.

Used for the on-site conversion of saline solutions into usable dosages of radiopharmaceuticals, Medi-RayTM's tungsten heavy alloy generator shields provide both the efficiency and the safety that is our hallmark.

Since introducing its first Technetium99 generator in 1972, Medi-RayTM has continued to perfect its tungsten heavy alloy generator shields designs and has become the recognized world leader in the manufacture of Technetium99 generators.

Our physicists and engineers have over 34 years of expertise in designing and manufacturing the tungsten generator shields solutions to meet your needs.

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.

The Advantages of Tungsten Heavy Alloy Generator Shields

tungsten generator shieldsThe density of a material is related to its radiation stopping ability. Higher density means better stopping and absorbing radiation ray. Due to a higher density than most other materials, tungsten heavy alloy generator shields has a much higher ability of absorbing and stopping almost rays than others metals such as the traditional radiation shielding - lead. Tungsten radiation shielding greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten heavy generator shields provide diminished exposure risks than equivalent lead shielding.

Tungsten heavy alloy generator shields 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. Tungsten heavy alloy generator shields can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of tungsten heave alloy generator shields and containers. Besides, compared with lead or depleted uranium (DU), tungsten generator shields is more friendship for the environments both lead and DU for it is no any toxic.
