Tungsten Nuclear Radiation Shield

What Is Tungsten Nuclear Radiation Shield?

Tungsten nuclear radiation can be broadly classified into three categories. These three categories are labeled with the first three letters of the Greek alphabet: ? (alpha), β (beta) and γ (gamma). Alpha radiation consists of a stream of fast-moving helium nuclei (two protons and two neutrons). As such, an alpha particle is relatively heavy and carries two positive electrical charges. Beta radiation consists of fast-moving electrons or positron (an antimatter electron). A beta particle is much lighter than an alpha, and carries one unit of charge. Gamma radiation consists of photons, which are without mass and carry no charge. X-rays are also photons, but carry less energy than gammas. Some materials absorb beta rays. You can measure this absorption by fixing beta source and a radiation monitor so their positions do not change.

Tungsten heavy alloy has high absorption rate on X rays and gamma rays. Tungsten is 60% better than lead in shielding against X rays and gamma radiation therefore; it can be significantly reduced in size.

Tungsten nuclear radiation shielding also has another characteristic, very high melting point. By this, tungsten alloy nuclear radiation shielding can be used in high temperature which can not be used with lead, for example nuclear scrap container.

Due to its unique characteristics, people use tungsten alloy nuclear radiation shield in medicine, tungsten nuclear radiation shielding, such as collimator, tungsten alloy nuclear radiation shielding, beamline , PET syringe shield, vial shield, tungsten alloy nuclear radiation shielding is used to protect workers from the radioactive sources of the scanner used in security and aerodrome, coach stop, etc. Tungsten alloy nuclear radiation shielding is also used in the equipment of industrial radiography, pipe-line inspection (collimator or tungsten nuclear radiation shielding).

Nuclear Radiation Damage

radiation sign
It can damage cells and the DNA inside them through its ionizing effect. This effect happens when a high-energy carrying particle or photon removes an electron within an atom's nucleus from its orbit, thereby changing the properties of the atom. If enough ionization enters DNA, cell and tissue damage result. Radioactive materials can enters the body through breathing, skin wounds and gastrointestinal absorption, causing inside radiation and outside radiation being absorbed into the body, and causing radiation damage. Common symptoms of radiation poisoning are; fatigue, dizziness insomnia, skin redness, ulcers, hemorrhage, hair loss, leukemia, vomiting, diarrhea, etc. What is worse, distorted DNA can increase, hereditary disease incidence, affecting the health of several generations.

The more radiation person receives, the more serious the radiation sickness symptoms and the greater the risk that the cancer and birth defects. So tungsten nuclear radiation shielding is necessary for us.

Why Use Tungsten Alloy Nuclear Radiation Shield?

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy nuclear radiation shielding provide excellent density with small capacity. At the same weights high density alloy can provide the same energy absorption as lead using 1/3 less material. In weight certain, high-density tungsten alloy can better resist radiation, and tungsten alloy nuclear radiation shielding is thin, more convenient than others.

While designing shielding, tungsten alloy nuclear radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
Formula: K=e0.693 d / △1/2
K: Shield weakened multiple
△ 1/2: The tungsten nuclear radiation shielding material of the half-value layer values
