Tungsten alloy container is the most commonly used for radioactive source to transport or store radioactive materials, as it has High density, hardness, wear and good impact resistance and durability.

Container for radioactive source storage is usually made of tungsten alloy for transportation or storage of radioisotopes or other radioactive materials. Radioactive materials release many kinds of radiation in decay reactions, which can often cause adverse effects on human. Therefore, it is necessary to look for substances that can shield these rays as containers. The transport container for radioactive materials is the only physical barrier for safe transportation of radioactive substances, and transport containers need to be able to withstand possible collision accidents.

 

 

The three elements of radiation protection are distance, time and shielding, or the main means of radiation protection are time protection, distance protection and shielding protection. During practical work, due to the limited conditions, it is impossible to achieve safe operation only by shortening the contact time and increasing the distance. For example, a large 60Co radiation source is installed in a room, and the maximum distance from the staff is only a few meters which is very dangerous to stay there even for a second. Therefore, shielding materials must be used.

 

According to the principle of radiation would weakened when crossing material, shielding is that put a shielding layer of sufficient thickness between the human and the radiation source (less material), to reduce the dose to below the standard control, to protect human safety. The material used for shielding depends on the nature of the radiation, type, amount of output, and the material thickness is determined by the control level. It usually uses tungsten alloy container for radioactive source storage.
