Gamma radiation is the product of radioactive atoms. Depending upon the ratio of neutrons to protons within its nucleus, an isotope of a particular element may be stable or unstable. When the binding energy is not strong enough to hold the nucleus of an atom together, the atom is said to be unstable. Atoms with unstable nuclei are constantly changing as a result of the imbalance of energy within the nucleus. Over time, the nuclei of unstable isotopes spontaneously disintegrate, or transform, in a process known as radioactive decay. Various types of penetrating radiation may be emitted from the nucleus and/or its surrounding electrons. Nuclides which undergo radioactive decay are called radionuclides. Any material which contains measurable amounts of one or more radionuclides is a radioactive material
Industrial radiography is the use of ionizing radiation to view objects in a way that cannot be seen otherwise. It is not to be confused with the use of ionizing radiation to change or modify objects; radiography's purpose is strictly viewing. Industrial radiography has grown out of engineering, and is a major element of nondestructive testing. It is a method of inspecting materials for hidden flaws by using the ability of short X-rays and gamma rays to penetrate various materials
Homeland Security and Border Control
The September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon starkly revealed a dark side of globalization. Global flows of information over the internet, increasing international business travel, tourism, and foreign study provided convenient cover for the terrorists as they carefully planned their attacks. The freight transportation revolution made possible by intermodal shipping containers enabled a vast expansion of international trade and an acceleration of globalization but these shipping containers are all too susceptible to use as delivery vehicles for weapons of mass destruction. This research program examines the increasing trade, travel, migration that is part and parcel of globalization in light of new demands on border control required to provide homeland security.
The radioactive sources are very strong and require WOLFMET tungsten shielding to protect security staff and members of the public from the radiation. A tungsten collimator is also required to direct the gamma radiation onto its target
Tungsten Alloy Plasma Accelerator Shieldin
As radiation becomes a problem. To protect body from radiation is very important. Radiation shielding for plasma accelerator is quite necessary. Depending on heaviest density but smallest capacity, tungsten alloy material is more and more popular be used for making tungsten alloy shielding to protect body from plasma accelerator radiation. Compared with lead, tungsten is much smaller but with heavier density, which is very helpful for high radiation absorption. It is more than 60% denser than lead, meanwhile, it has excellent machinability, good corrosion resistance. The most important thing is that, tungsten material is environment-friendly
