Tungsten Alloy Radiation Shielding for Ionizing Radiation

Ionizing radiation refers to electromagnetic radiation and ionizing radiation which can make atom or atomic group produce ionization. Electromagnetic radiation which can cause ionization contains X-ray and γ-ray. Ionizing radiation contains α-ray, β-ray, neutron, proton and other charged particle. In nuclear medical, primary source of radioactivity is various kind of radioactive medicine, unsealed source also called as open source. Its characteristic is spreading easily and polluting working space and environment. Working space of operating unsealed source has externalir radiation exposure caused by X-ray, γ-ray andβ-ray. It also has internal radiation exposure caused by radionuclide which is produced by radioactive pollution entering into organism.

In recent years, PET/CT centers have been established in some large medical therapy units gradually, in China. Source of radioactivity is more complicated. It comes from the externalir radiation exposure and internal exposure radiation caused by radionuclide of positron which utilized by tungsten alloy PET and marked medicine. It also comes from externalir radiation exposure produced by tungsten alloy CT. It even comes from externalir radiation exposure and induced radioactivity caused by small cyclotron when producing radioactive element and internal radiation exposure caused by pollution of radionuclide. Tungsten alloy radiation shielding can be used for protecting doctors and patients from ionizing radiation.
