A two-layer composite shielding system known as the Di-layer Satellite Electronic Shielding System has been fabricated from biomass and geological ores to protect satellite electronics from high-energy radiation. The material utilises low atomic number components arranged in two distinct configurations. Laboratory testing demonstrates that the composite possesses mechanical strength, providing resilience against launch vibrations and impacts with low-velocity space debris. Thermal analysis indicates stability in high-temperature environments, showing minimal decomposition. In radiation testing, the composite effectively attenuates gamma radiation from Cobalt-60 sources, with the LH configuration yielding superior attenuation performance. It also reduces high-energy beta particles produced by a medical linear accelerator by more than 93 percent. This lightweight and cost-effective composite offers enhanced protection against damaging space radiation, including cosmic rays, with potential utility across space and medical sectors.
Space radiation, particularly high-energy beta particles and gamma rays, can severely damage satellite electronics and cause critical mission failures. Providing an effective shield derived from biomass and geological ores offers a lightweight, cost-effective alternative to conventional shielding. This development helps safeguard satellite systems against launch stresses, space debris, and orbital radiation, while also showing promise for medical radiation protection.
The composite addresses manufacturers of satellite electronic systems and providers of medical radiation equipment seeking lightweight, cost-effective shielding materials. Based on the abstract, the technology is at the stage of laboratory fabrication and characterisation, having undergone mechanical, thermal, and radiation attenuation testing using cobalt and medical linear accelerator sources. Moving toward real-world deployment will require further functional validation within operational space environments or integrated medical devices.

Satellites in space are vulnerable to high-energy electrons above that can damage their electronic systems. To curtail this challenge, a new multi-layer system is synthesized from biomass and geological ores and characterized for mechanical, thermal as well as gamma and beta radiation shielding efficiencies. The new system, a Di-layer Satellite Electronic Shielding System (DiLSES), featuring an innovative, light weight, two-layer material composite made from low atomic number material labeled which are arranged in two configurations LH and HL. This advanced material shows exceptional mechanical characteristics with impact strength of hardness of and tensile strength of, making it resistant to launch vibrations and collision with low velocity space debris. Thermogravimetric analysis (TGA) revels that DiLSES can withstand high temperature environment of up to 300 and only gradually decomposes by less than 5% between and For gamma radiation shielding efficiency, the DiLSES effectively attenuated pointed gamma radiation from Co-60 with maximum energy of 1.332 MeV by and for and the LH configuration offers better attenuation. The DiLSES attenuates high-energy beta particles generated by medical LINAC by over 93%, achieving a remarkable reduction at energy .This innovative light-weights and cost-effective material has the potential to improve the shielding of electronic components in satellites against high-energy beta particles (greater than 1 Mev) which cause satellite damage and operational failures. It also offers protection from space radiation like gamma and cosmic rays, making it useful for both space and medical applications.
