“…This ionization releases high energy and promotes the rupture of bonds of biological material such as DNA. This can occur directly or indirectly due to the generation of free radicals such as hydroxyl radical yielded from water present in cells (Figure 1) [5]. Therefore, protection against high-energy radiation is an important challenge to address.…”

This paper revises the use of polymer nanocomposites to attenuate high-energy electromagnetic radiation (HE-EMR), such as gamma radiation. As known, high-energy radiation produces drastic damage not only in facilities or electronic devices but also to life and the environment. Among the different approaches to attenuate the HE-EMR, we consider the use of compounds with a high atomic number (Z), such as lead, but as known, lead is toxic. Therefore, different works have considered low-toxicity post-transitional metal-based compounds, such as bismuth. Additionally, nanosized particles have shown higher performance to attenuate HE-EMR than those that are micro-sized. On the other hand, materials with π-conjugated systems can also play a role in spreading the energy of electrons ejected as a consequence of the interaction of HE-EMR with matter, preventing the ionization and bond scission of polymers. The different effects produced by the interactions of the matter with HE-EMR are revised. The increase of the shielding properties of lightweight, flexible, and versatile materials such as polymer-based materials can be a contribution for developing technologies to obtain more efficient materials for preventing the damage produced for the HE-EMR in different industries where it is found.

“…Helium cannot be manufactured as it main source in earth comes from the radioactive decay of uranium during millions of years. 2 Only a reduced number of natural gas wells have the enough helium concentration to perform an efficient extraction. 3 In fact, some shortages have taken place in recent years and this has a huge impact on the scientific fields using helium.…”
