Fluorine-18 Tungsten Radiation Shielding

Fluorine-18 tungsten radiation shielding is usually used to shield radiation released when producing and using fluorine-18 and its compounds.Fluorine-18 is a radioisotope of fluorine with half-life of 109.771 minutes that plays an important role in positron source. It decays by positron emission 97% of the time and electron capture 3% of the time. Both forms of decay yield stable oxygen-18. Fluorine-18 is primarily synthesized into fluorodeoxyglucose to use in the radiopharmaceutical industry. It can be used as a tracer in positron emission tomography scan. Use of this tracer to detect the possibility of cancer metastasis is the most frequent type of PET scan in standard medical care.

Fluorodeoxyglucose also can be applied to evaluate the glucose metabolism in the heart, lungs and the brain, and to image tumors in oncology, where a static F-FDG PET scan is performed and the tumor F-FDG uptake is analyzed according to Standardized Uptake Value. FDG-PET can be used for diagnosis, staging, and monitoring treatment of cancers, particularly in Hodgkin's disease, non-Hodgkin's lymphoma, breast cancer, melanoma, colorectal cancer, and lung cancer. It has also been approved for using in diagnosing Alzheimer's disease. Since fluorine-18 is radioactive and toxic, tungsten radiation shielding is usually used to shield radiation released when producing and using fluorine-18 and its compounds.

Fluorine-18 tungsten radiation shielding is made of tungsten alloy with high density. According to the research, the radiation shielding performance of a metal material is closely related to its density .AS the density is higher, the radiation shielding performance is greater. Therefore the radiation shielding performance of fluorine-18 tungsten radiation shielding is great. Fluorine-18 tungsten radiation shielding is a best choice for shielding radiation generated during the preparation and the use of fluorine-18 and its compounds. In addition, tungsten alloy is environmental non-toxic so as not to pollute the environment or endanger human health.
