・Excellent high radiation shield factor for inorganic oxidized compounds has been measured.
 ・As SOMA is an oxidized compound of several inorganic materials, it is eco-friendly with a small number of resource constraints.
 ・Thanks to optimized proprietary crystallization technology, SOMA is hydrolysis resistant, heat tolerant, and long lasting.
 ・Available in various forms: powder, gel, liquid and solid; complexation and hybridization with various substances as well as
   free-form fabrication – can be easily achieved, thanks to its high affinity with resin, metal and glass.
 ・Achieved both specific gravity as light as 3.61 and properties of high-specific heavy metal.
 ・Excitation confirmed in a wide spectrum from ultraviolet to visible and infrared rays.
 ・Promising as a next-generation, highly-efficient device.


 ・Although light-weight and allows for highly flexible fabrication, a remarkable X-ray shield factor – approximately 95% – was measured.
 ・Excellent high gamma irradiation shield factor for inorganic compounds (about 62%) has been measured.
 ・Excitation was observed in a wide optical range such as the 200-900nm wavelength range (ultraviolet to infrared rays), as well as radioactive wavelengths.
   It can be used as a next-generation, highly-efficient device.
 ・Measured shield factors for fast neutron radiation and total neutron radiation – both harmful to humans – were 49% and 83%, respectively.
 ・An electron-beam shield factor of approximately 96% was measured.

Radiation Shielding

  Measured radiation shielding factor: X rays: 95%; gamma rays (cesium): about 62%; total neutron rays: 83%; and electron rays: 96%.

  SOMA is a light-weight, highly-workable, and eco-friendly material that can be combined with other materials to create a hybrid compound.
  Leading testing institutions in Japan have measured SOMA’s high level of radiation shielding performance. SOMA is a true radiation shielding material
  with proven capability.
