Product description

Luoyang Achemetal Tungsten & Molybdenum Technology Co., Ltd. has proven technology and equipment for the production and finishing of tungsten and tungsten alloy blanks to produce high quality pure tungsten radiation shielding materials for medical and industrial applications. Our company can produce pure tungsten radiation shielding materials and tungsten alloy radiation shielding materials for shielding walls and radiation shields against X-rays and gamma rays.

Industrial Radiation Shielding Material

With extremely high density, tungsten and tungsten alloy have extremely high ray absorbing capacity, cover a smaller area than lead and boron carbide, are difficult to wear and do not pollute the environment. Therefore, tungsten and its alloy materials are increasingly applied to the shielding of X-rays and gamma rays, for example, medical ray detection and treatment equipment, circular accelerators, nuclear reactors, remote pipe probing equipment, etc.

Radiation Shielding Material for Medical Treatment

High-precision Tungsten Device for CT Collimator and Detector

Collimators are divided into two kinds in medical CT:

I. X-ray pipe side collimator also called front collimator is mounted in front of a CT bulb pipe, and is the first part through which X rays pass. X rays emitting out of bulb pipes are conical, and can obtain a thin light beam after passing through a tungsten device with narrow seams. Its main function is layer thickness selection of X rays. It can control the width of X ray beams in the parallel direction of long axis of a human body, thus controlling the thickness of scanning layers.

II. Detector side collimator is also called rear collimator of which narrow seams are respectively aligned with each detector, so that detectors can only receive rays emitting into detectors vertically, so as to reduce the interference of scattered rays from other directions as much as possible.

Developing rapidly, medical CT technologies have developed to the sixth generation at present. The quantity of detectors is increased further, so the using amount of high-precision tungsten devices is increased obviously, and the devices need replacing at regular intervals.

Medical Protective Storage Tank

With a good radiation shielding property, tungsten and tungsten alloy are used for manufacturing radioactive substance shielding walls as well as containers for storing and transferring radioactive substances in the medical field

Tungsten-based high specific gravity shielding material used in the Gamma Knife

Gamma Knife is a gamma stereotactic radiation therapy system, the main structure of which is a hemispherical helmet covered with collimators, which emits high-dose ionized rays generated by cobalt 60, i.e. gamma rays. Through geometric focusing, the rays are focused on the target-target in the patient's body through stereotactic orientation.

The tungsten-based high specific gravity shielding material is used to focus the rays without causing damage to the patient's health and medical personnel due to radiation leakage.

Tungsten-based high specific gravity shielding materials are used for gamma knife shielding because they provide better shielding than lead and are more environmentally friendly than lead.
