Tungsten Radiation Shielding for Nuclear, Medical & NDT

MarShield Radiation Shielding are experts in the in the customization of tungsten heavy alloy for the Nuclear Energy, Nuclear Medicine / Radioisotope, diagnostic imaging and non-destructive testing industries.

Limiting exposure to radiation is achieved by using materials that maximize shielding. The denser the material, the higher degree of shielding it provides. With a density approximately 1.7 timers higher than lead, Tungsten Heavy Alloy shielding guarantees radiation exposure is kept to a minimum. It is a viable option for many applications where lead is not feasible and is strong and highly customizable into precision components.

Why Tungsten?

Tungsten Radiation Shielding has a density of up to 18.89 g/cm3 vs. lead at 11.34 g/cm3.  It’s ease of mechanical processing / machining, high ductility and strength makes it a viable option for many applications where lead is not feasible whether it be for size reduction, maximizing weight in large or small cavities or for radiation shielding. Tungsten Radiation Shielding is strong and highly customizable into precision components.


Tungsten Heavy Alloy is the best choice for medical and industrial settings that require radiation shielding. It provides excellent value and uses less material than lead to provide the same level of absorption.

Radiation Protection – Nuclear, Medical & NDT

An excellent material for shielding, Tungsten Heavy Alloy guarantees minimum radiation exposure and ensures ALARA goals in the workplace. Machinability, radiographic density, strength, low toxicity, and heat resistance allow for superior design adaptability vs. other shielding materials.

Tungsten Heavy Alloy shielding is not subject to NRC, EPA, and OSHA regulations for special constraints and is used as:

  • Isotope vials and containers
  • Custom shielding components
  • Collimators for x-ray detectors
  • Multi-leaf collimators
  • Collimators for radiosurgery
