Geologging which is known as wireline logging and borehole logging is an exploration technique used in the oil and gas industries. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. Tungsten alloy radiation shielding can help you to overcome the problem.

This data can then be analysed to determine whether deposits of gas or oil are present. Tungsten alloy radiation shielding is used to shield the radioactive source and to act as a collimator for the gamma beam. Tungsten alloy is the best material for radiation shielding because the properties of tungsten alloy that is high density, small volume, good radiation resistance, etc.

With the development of our daily life, more and more high technologies are used by people, including computer tomography used in medical. The computer tomography is a medical instrument which produces 3-dimensional X-ray images of the area in question. Several X-ray tubes are contained. In such an X-ray tube we find an electron gun whose electrode is made of tungsten and furthermore a rotating anode also made of tungsten or a tungsten-rhenium alloy.

The shielding of the whole machine is done by tungsten alloy radiation cover (as a replacement for lead, which was used in earlier days). Tungsten alloy has the property of high radiation absorption, so it is the best material to make radiation shielding, tungsten alloy radiation cover is better than the radiation shielding made of lead for it is non-toxic. Tungsten alloy radiation cover is widely used in medical area to protect us from computer tomography radiation.

Tungsten alloy multileaf collimator is widely used in radiology departments and are an integral part of radiotherapy. Tungsten alloy also named tungsten heavy alloy is the best material to make tungsten alloy multileaf collimator for it has the so many good properties, such as high density, small volume, high radiation absorption, high temperature resistant and so on.

Tungsten alloy multileaf collimator is used in a variety of diagnostic and therapeutic medical technologies. High-density alloys for multileaf collimators are used to comprise the individual leaves, which can move independently in and out of the path of a particle beam. This crucial device directs a beam and focuses radiotherapy treatment to precisely conformed shapes, delivering correct therapy doses to patients.
