Tungsten Radioactive Source Holder

Tungsten shielded devices for holding a source of radioactive material and directing a beam of radiant energy there from for medical therapy and other purposes; and more particularly to such source holder devices as comprise a main body for containing the radioactive source and shielding the same in a safe manner when in a repose position, and a radiation emergence portion into which portion said source is moved for registry with a radiation emergence laperture therein.

Tungsten source holder device having improved means for effecting actuation of the radioactive source from its repose position to its active position whereby such actuation is greatly facilitated and fail-safe operation of the device is assured.

Tungsten alloys is a best choices for source holder device for tungsten alloys shielding provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy's reliable radiation shielding properties. It can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Tungsten heavy alloy source holder device have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Due to their high density, tungsten alloys offer greater radiation shielding than lead and are non-toxic.
