Tungsten alloy FDG radiation container is used for containing FDG and widely used in medical field. F-FDG or FDG, is a radiopharmaceutical used in the medical imaging modality positron emission tomography. Chemically, it is 2-deoxy-2-fluoro-D-glucose, a glucose dervative, with the positron-emitting radioactive isotope F-18 replaced for the normal hydroxyl group at the 2' position in the glucose molecule. F-FDG is now the standard radioactive tracer used in PET neuro imaging and cancer patient management.

F-FDG can be applied to the evaluation of glucose metabolism in the heart, lungs and the brain. It is also applied 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.

The tungsten alloy FDG radiation container is necessary when producing or using FDG. Because, the elemental fluorine is highly toxic to living bodies. Its effects in humans start at concentrations lower than hydrogen cyanide's 50 ppm and are similar to those of chlorine: significant irritation of the eyes and respiratory system as well as liver and kidney damage occur above 25 ppm, which is the immediately dangerous to life and health value for fluorine. Eyes and noses are seriously damaged at 100 ppm, and inhalation of 1,000 ppm fluorine will cause death in minutes, compared to 270 ppm for hydrogen cyanide.

Tungsten alloy FDG radiation container has high density. The density of a material is related to its radiation protection ability. Higher density means better stopping and absorbing radiation .Therefore, tungsten alloy FDG radiation container can shield radioactive fluoride and its compounds to avoid them doing harm on humans. And tungsten alloy is environmentally non-toxic so as not to pose a threat to the surroundings.
