Polymer-Composite Materials for Radiation Protection

Trends in reinforced composite design for ionizing radiation shielding applications: a review

“…They proposed that the fillers must satisfy the condition of 8 [ pH [ 5 and the expected high density could be achieved by the addition of more mineral reinforcements. Barabash et al [76] similarly concluded that mixing reinforcers and matrix at high difference in the potential of hydrogen will result in the release of gaseous products in the boundary layer. Haque et al [77] used locally available heavy minerals with Ilmenite, Magnetite, Garnet, Rutile, Zirconium contents to fabricate the composite blocks for the gamma photons with energies 0.662 meV-1.25 meV.…”

Electrospun Tungsten‐Polyurethane Composite Nanofiber Mats for Medical Radiation‐Shielding Applications

“…X‐ray based radiation technology has been actively utilized in the industrial, agricultural, and medical fields, and recently its use has gradually expanded to encompass chemistry, biology, environment, and informatics [1,2] . Given the acute health effects such as skin burns, radiation syndrome, and potential cancerous diseases upon exposure to high levels of X‐ray radiation, more attention has been paid to the development of effective shielding materials [3,4] .…”

“…Given the acute health effects such as skin burns, radiation syndrome, and potential cancerous diseases upon exposure to high levels of X‐ray radiation, more attention has been paid to the development of effective shielding materials [3,4] . Practically, radiation‐shielding materials are often used in power plants, medical diagnostic centers, nuclear research establishments to protect personnel in the form of a thick film, wall, or glass containing high atomic number elements (e. g., lead, tungsten, and bismuth) that can effectively block various radiation sources and doses for human body [1,2,4–7] . Industrial and medical facilities typically build specially isolated areas to prevent external exposure of the radiation generated by certain machineries, and shielding sheets or suits are commonly used to protect workers from being exposed to high levels of radiation doses.…”

“…Industrial and medical facilities typically build specially isolated areas to prevent external exposure of the radiation generated by certain machineries, and shielding sheets or suits are commonly used to protect workers from being exposed to high levels of radiation doses. Thus, professionals have actively utilized portable radiation equipment including wearable shielding suits to minimize their exposure to hazardous radiation sources [2,8,9] …”

“…The development of non‐woven fabric‐type shielding sheet manufactured from layers of fibers could overcome the disadvantages of the film‐type shielding sheets, but readily decrease the shielding rate as radiation could go through the pinholes formed by macro size fabric pores [17,18] . As a way to supplement the disadvantage of macro pinholes, nanoscale fiber‐based materials with high fiber density can greatly reduce pore size to effectively prevent from radiation penetration but highly improve flexibility and air permeability by increasing porosity [2,19] …”
