“…Furthermore, it is crucial to investigate how different types of ionizing radiation (e.g., X-rays, gamma rays, neutrons, protons, and alpha particles) and their energies influence NTE responses [67]. While there is a lot of work published in this field, there are significant anomalies, such as the fact that neutrons (where gamma contamination of the beam is totally shielded) do not seem to produce a bystander effect or genomic instability [68][69][70]. Another issue is that alpha particles produce genomic instability but the evidence for the induction of bystander signaling is contradictory and controversial [71].…”

It is well established that cells, tissues, and organisms exposed to low doses of ionizing radiation can induce effects in non-irradiated neighbors (non-targeted effects or NTE), but the mechanisms remain unclear. This is especially true of the initial steps leading to the release of signaling molecules contained in exosomes. Voltage-gated ion channels, photon emissions, and calcium fluxes are all involved but the precise sequence of events is not yet known. We identified what may be a quantum entanglement type of effect and this prompted us to consider whether aspects of quantum biology such as tunneling and entanglement may underlie the initial events leading to NTE. We review the field where it may be relevant to ionizing radiation processes. These include NTE, low-dose hyper-radiosensitivity, hormesis, and the adaptive response. Finally, we present a possible quantum biological-based model for NTE.

“…Among these materials, boron steel and boron carbide (B 4 C)/aluminum (Al) composite materials are notable examples, where they rely on the high thermal neutron absorption cross-section of boron-10 ( 10 B) [7]. These materials find application in the storage racks and transport casks used for SNF.…”

Developing next-generation thermal-neutron-shielding and -absorbing materials for the safe storage and transportation of spent nuclear fuel is a topic of active research in academia. Gadolinium (Gd) boasts superior neutron absorption capacity compared with other nuclei. Consequently, it has garnered significant attention as a potential replacement for boron in spent nuclear fuel (SNF) applications. In this study, the austenitic stainless steels 304 and 316 and the duplex stainless steel 5A were reinforced with 2 wt.% of gadolinium to explore their thermal-neutron-absorbing efficiency. Their properties were then compared with commercial-grade borated stainless steel, as per ASTM standard A887. After the inclusion of Gd, both the yield strength and ultimate tensile strength of the alloys slightly increased, which was attributed to the evenly distributed Gd intermetallics within the matrix. However, the elongation rate was reduced. The Charpy impact absorption energy also decreased. The influence of the Gd intermetallic was further explored by examining the fractography. While the corrosion resistance of the alloy slightly diminished after the addition of Gd, its neutron absorption capacity demonstrated superior performance, especially when the Gd content was equivalent to that of boron. Although most properties of the experimental alloy deteriorated after the Gd addition, they still outperformed commercial borated stainless steel, suggesting that this alloy might be a promising candidate for SNF applications.

The continuous development of ionizing radiation in medical imaging and treatment, nuclear reactors, food irradiation, and other fields is accompanied by potential risks. It protects related equipment and personnel by adopting radiation shielding materials to reduce irradiation. Due to the advancement of science and technology, many high‐performance radiation protection materials have been reported. Ionizing radiation is a complex environment involving X‐ray imaging, radiation therapy, nuclear power operation, and space radiation. Irradiation energy, irradiation type, and the measurement of shielding material have essential effects on shielding efficiency. However, there has not been a general review of the preparations and properties of ionizing radiation shielding materials in the light of different matrixes in recent years. Herein, a comprehensive overview of recent advancements in radiation shielding materials, categorized into alloys, concretes, glasses and ceramics, and polymer composites, is presented. Furthermore, the synthesis methods employed for these materials and their respective radiation shielding properties are discussed. Finally, the current research gap and possible future scope of radiation shielding materials are proposed.
