What is Carbon 14

Carbon 14, 14C, or radiocarbon, is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Carbon 14 decays into nitrogen 14 through beta decay. A gram of carbon containing 1 atom carbon 14 per 1012 atoms will emit 0.192 beta rays per second. The primary natural source of carbon 14 on Earth is cosmic ray action upon nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide.

The Applications of Carbon 14 tungsten radiation shielding

Due to its high density, excellent absorption behaviour against radiation and environmental friendly characteristics, tungsten alloy can be widely used to produce Carbon 14 tungsten radiation shielding. Carbon-14 compounds are widely used in chemical and biological research. The different isotopes of carbon do not differ appreciably in their chemical properties. This is used in chemical and biological research, in a technique called carbon labeling: carbon 14 atoms can be used to replace nonradioactive carbon, in order to trace chemical and biochemical reactions involving carbon atoms from any given organic compound.

The Advantages of Carbon 14 tungsten radiation shielding

The thickness 3mm of tungsten alloy shield can shield 95% of 150keV γ radiation. Tungsten alloy shield is suiting for high spatial resolution occasion, such as radiological Imaging array detectors. Tungsten alloy shield has high density, which is 60% higher than lead, could reach the same absorption radiation effective with the smaller size. Tungsten alloy shield has the ability of various high-ray shielding. Tungsten alloy Compared with lead, when they with the same performance of radiation shielding, the volume of tungsten alloy is 1/3 of lead.Carbon 14 tungsten radiation shielding is a kind of environmental protection material, which is less damage than lead.

During design of shielding, tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
Formula: K=e^{0.693 d / △1/2}
K: Shield weakened multiple
△ 1/2: The tungsten alloy radiation shielding material of the half-value layer values
