Tungsten vial shielding is are radiation protection tool made out of high-density tungsten alloy, which combines high density, great shielding capabilities, and eco-friendly properties. In medicine, they are mainly used for the safe storage of radiopharmaceuticals or radionuclides used in radiotherapy. These containers are used for the safe storage of radiopharmaceuticals and protection from synthetic radionuclides, for example, cobalt-60 and cesium-137. These are the most optimal containers for the transport of radiopharmaceuticals in combination with tools for medical protection. This container achieves radiation shielding due to the density of the materials, which are in the range of 16.5 to 19.0 g/cm³ and are capable of 80% radiation attenuation. In comparison to normal protective lead containers, the tungsten containers are better as they are non-toxic, do not generate secondary pollution, and are recyclable.
Tungsten vial shielding, with its high densities, high strengths, and excellent radiation shielding properties, has outshone in various fields of applications. In the field of nuclear medicine, these containers are specifically meant to store radiopharmaceuticals. Because of the high-density materials, these containers ensure significant protection from gamma rays and X-rays, thereby safeguarding the medical staff and patients. For example, tungsten alloy shielded containers are used to safely store radiopharmaceuticals during positron emission tomography (PET) and radiotherapy, ensuring precise control of radiation dose while reducing the risk of environmental leakage.
