Why Tungsten Can Prevent Damage from Radioactive Radiation

The Basic Concept of Radioactive

Nuclei of certain substances can decay and emit invisible nor do I feel that we can only use specialized equipment to detect radiation . Substances of this nature is called radioactivity.

Radioactive Pollution Sources and Classification

1 ) Nuclear weapons test fallout ( nuclear tests in the atmosphere, the case of a nuclear bomb explosion in the moment, by the hot steam and gas formation of large balls ( ie mushroom ) carrying the shell , debris , ground material and radioactive plume rise , with the and air mixture , a gradual loss of radiant heat , the temperature gradually decreased , so the gaseous material condensed into particles or dust particles attached to the other , and finally settling to the ground .

2 ) The nuclear fuel cycle "three wastes " discharge atomic energy industry is the central issue of nuclear fuel production, use and recycling all stages of the nuclear fuel cycle will have a " three wastes" , to a certain extent on the surrounding environment pollution .

3 ) Medical exposure caused by radioactive contamination present, due to radiation in medicine widely used, has become a major source of the Medical Radiation artificial environment pollution .

4 ) Other aspects of radioactive contamination of other sources of radiation pollution sources can be grouped into two categories: industrial, medical, military, nuclear ships, or research use of radioactive sources , due to transport accidents , loss , theft , misuse and waste treatment causing loss of control and high-dose radiation to the residents or to the environment ; Second, general consumer goods, including natural or artificial radionuclides containing products, such as radioactive luminous dial, luminous watch and color TV produced by irradiation , though the environmental pollution is very low, but there are also studies is necessary.

Radiation on The Human Body

In large doses of radiation, radioactive humans and animals there is some damage effect. If the 400rad irradiation, irradiated 5% of people who have died ; if irradiation 650rad, then 100% of people died. In 150rad less radiation dose , the mortality rate is zero, but not without damaging effects , live to subject 20 years later, some of the symptoms will be manifested. Radiation can damage genetic material , mainly caused by gene mutations and chromosomal aberrations, a generation or even generations suffer.

As medical technology advances, more and more radiant life , has caused new problems, these rays are X-rays, gamma rays , α -rays , β -rays. Tungsten alloy is used to make the best of the shield material , whether medical or industrial equipment. Compared with conventional shielding materials , tungsten alloy shielding member reflects good value. High density alloy can be provided as the energy absorption , and the volume of lead less than 1 /3 of people using the tungsten alloy can be a good and reliable shielding performance. Our common language tungsten alloy radiation shielding container shielded gamma shielding and industrial supplies . Shield member can also be used collimators , cancer treatment and radiation shielding syringe . In order to protect patients and health care workers , it is necessary to use shielded tungsten alloy equipment these harmful radiation.

The researchers found that radiation capacity and material density, the greater the density shielding performance is better. Has great density tungsten alloy , so it's shielding performance is high, and tungsten alloy product is environmentally friendly , than lead less hazardous products . Tungsten alloy products are used to make the best shield materials, non-toxic and easy processing .
