Tungsten Alloy Cluster Bomb 393

Tungsten alloy cluster bomb, which is also known as tungsten alloy cluster munition, is a container filled with small explosive bombs called “sub-munitions.” This container may be a shell, rocket, missile, or other device. Dropped from an aircraft or fired from the ground, it opens in the air and releases the tungsten alloy sub-munitions. This scatters a carpet of bombs over a large area without any degree of accuracy, to attack cluster targets such as cluster tanks, armored combat vehicles,…

Tungsten Alloy Pinhole Collimator 325

Tungsten alloy pinhole collimator is widely used in gamma camera for medical diagnosis. Wherein, tungsten alloy is a new type of environmentally friendly radiation shielding material that has better shielding capacity than poisonous lead to protect doctors and patients from radiation pollution. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html It has been reported that the conventional knife-edge collimator is not suitable for nuclear imaging system because many scattering radiations near the pinhole aperture happen and blur image. So, the researchers introduced a…

Product
Tungsten Alloy Converging Collimator 294

Tungsten alloy is more and more widely used for radiation protection to shield people or objects from radiation. For example, it is promising in applications of converging collimator – an important part of human brain SPECT, which is known to increase the photon detection efficiency compared to conventional parallel-hole collimator in SPECT imaging. That is because tungsten alloy is poison-free with better radiation shielding ability than lead (poisonous). More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html It has been reported that a converging…
