Tungsten Alloy Radiation Shielding - Nuclear Medical Radiation
Shielding 7 - Density 18.5g/cc
Description
They are always used as radioactive source and transport
containers, FDG container, PET syringe shields and vial shield in
isotope production, transport, and containment. Apart from it, they
are used as all kinds of shielding and collimators in gamma
radiography or gamma camera, industrial instrumentation, nuclear
power plant and clinical point shielding, oncology isotopic,
accelerator based platforms and homeland defence like personal
protection equipment for emergency responders and large container
inspection devices, etc.
Advantage of Tungsten Alloy Radiation Shielding
Tungsten radiation shielding greater linear attenuation of gamma
radiations means that less is required for equal shielding.
Alternatively equal amounts of tungsten shielding provide
diminished exposure risks than equivalent lead
