Medical radiation shielding discription:
Tungsten alloy(heavy alloy) is ideal for shielding against X rays and gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics.
tungsten heavy alloy shielding is used in applications such as collimator, beamstop, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.


Positron emission tomography (PET)
Positron emission tomography (PET) is one of the medicine techniques available for diagnosis. Whilst X-rays provide information on the structure of the body, PET shows the chemical function of a particular organism. PET involves the injection of FDG (a glucose-based radionuclide) from a shielded syringe into the patient. As the FDG travels through the patients body it emits gamma radiation which is detected by a gamma camera, from which the chemical activity within cells and organs can be seen. Any abnormal chemical activity may be a sign that tumours are present,PET scans are frequently used to detect cancerous tumours and diseases of the brain and coronary arteries.


Applications for tungsten alloy shielding in PET include:


PET syringe shield
Tungsten vial shield
Tungsten FDG transport container
Collimator for gamma camera
Technetium generator


Multi leaf collimator
Radiotherapy destroys cancer by directing beams of radiation directly onto the tumour. The beams of radiation require a very fine focus to avoid harming the surrounding healthy tissue. This focus is achieved by using a multi-leaf collimator , consisting of two rows of very thin tungsten alloy plates, which can be configured to exactly match the dimensions of the tumour.
