Tungsten Heavy Metal Radiation Shell

Tungsten Heavy Metal Radiation Shell

Experiments on the generation of argon tungsten alloy radiation shell during the implosion of double-shell plasma liners are described. The optimum liner length with respect to the maximum tungsten alloy radiation shell yield is determined. At a liner current of ∼1.4 MA, the conversion efficiency of the generator electric energy into the tungsten alloy radiation shell energy attains 8–9%. The spectrum of the argon tungsten alloy radiation shell is measured by a set of photoemission X-ray diodes with different filters (including an argon gas filter). Based on the measurements of the emission power in different spectral intervals and calculations by the collision-radioactive model, the ion density and electron temperature of the pinch plasma are estimated. 

The usage of tungsten alloy radiation shell is not subject to NRC, EPA, or special OSHA regulations, so it has been widely used, such as:

Radioactive source containers

Gamma radiography shields

Shielding block

Source holders for oil well logging and industrial instrumentation

X-ray collimators

Tungsten alloy PET syringe shield

Shielding in cancer therapy machines

Syringe protection for radioactive injections

Tungsten syringe shielding

Nuclear shielding wall
