Model Number: C-96 Brand Name: CHENTIAN Key Specifications/Special Features: Tungsten alloy brachytherapyIt is possible to use an alternative type of radiotherapy, which is known as afterloading (a version of brachytherapy) when it is difficult to access the diseased cells directlyTungsten alloy brachytherapy technique consists of implanting a radioactive seed inside the patient's body, via catheterBefore and after treatment the seed is kept in a large tungsten safe, tungsten alloy radiation shielding is used to protect the patient and medical staff against radiation in the treatmentGuangxi Chentian Metal Products Co Ltd is a professional tungsten alloy products manufacturer that can provide all kinds of tungsten alloy radiation shielding products used in the technique of tungsten alloy brachytherapy shieldingWhen it is difficult to access the diseased cells directly, it is possible to use an alternative type of radiotherapy, known as after loading (a version of brachytherapy shielding)This technique consists of implanting a radioactive seed inside the patient's body, via catheterBefore and after treatment the seed is kept in a large tungsten safe, to protect the patient and medical staff against radiationTungsten alloy brachytherapy shielding purpose:Tungsten alloy brachytherapy shieldingis an integral part of treatment regimen for cervical cancer and, generally, outcome in terms of local disease control and complications is a function of dose to the disease bed and critical structures, respectivelyTherefore, it is paramount to accurately determine the dose given via brachytherapy to the tumor bed as well as critical structuresWhy use tungsten alloy brachytherapy shielding?
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy shielding provides 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
When the weight is certain, more density, denser, and the thickness would be thinner. Tungsten alloy brachytherapy shielding can be made with thinner thickness but high absorption of radiation in high density
That is why tungsten alloy material is suitable for radiation shielding
Tungsten alloy brachytherapy shielding is better than lead materials for it is nontoxic
During design of tungsten alloy shielding, it 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: shielding material of half-value layer values
d: Shielding thickness, with half-value layer thickness of their units, you need to half-value layer thickness of quality of translation into the thickness of the material, divided by the density of the material can be obtained
