Electronic devices that can survive exposure to high amounts of gamma radiation or electromagnetic pulses (EMPs) typically require specialized design and shielding to withstand these extreme conditions. Here are a few examples of devices that are designed to be resistant to such radiation:
Hardened military and aerospace electronics: Certain military and aerospace electronic systems are designed to operate in harsh environments, including exposure to gamma radiation and EMPs. These devices often incorporate shielding materials, robust circuitry, and redundant systems to ensure their functionality in extreme conditions.
Radiation-hardened integrated circuits (ICs): Radiation-hardened ICs are specifically designed to withstand high levels of radiation. They are used in applications such as space exploration, nuclear power plants, and particle accelerators. These ICs are built with materials and structures that are less susceptible to radiation-induced damage, such as single-event effects (SEE) or total ionizing dose (TID).
Faraday cages: A Faraday cage is an enclosure made of conductive material that can effectively block external electromagnetic fields, including EMPs. By creating a conductive shield around the electronic device, a Faraday cage can prevent the penetration of electromagnetic radiation and protect the equipment inside.
Shielded enclosures: Some electronic devices, particularly those used in critical infrastructure or sensitive facilities, are housed within shielded enclosures that can block or attenuate electromagnetic radiation. These enclosures are typically made of conductive materials, such as metal, and are designed to provide a barrier against external radiation sources.
It's important to note that while these devices and techniques offer increased resistance to radiation and EMPs, they may not be completely immune to all levels of exposure. The effectiveness of their protection depends on the specific design, shielding, and the intensity and duration of the radiation or EMP event.
For critical applications where protection against radiation or EMPs is vital, it is advisable to consult with experts in the field and follow industry standards and guidelines to ensure the appropriate level of protection for the specific environment and device requirements.
