The United States Nuclear Regulatory Commission (USNRC) defines it as the process of radiation attenuation achieved by placing an absorbent substance between an individual, a workspace, or a radiation ...

Space radiation has been identified as the main health hazard to crews involved in long-term interplanetary space missions. In deep space environment, without the protection of the terrestrial ...

In the left image, the conventional BNNT films-produced using randomly packed BNNTs-has a low density, making the film brittle and prone to breakage. In contrast, the developed BNNT liquid ...

High-energy cosmic radiation damages cells and DNA, causing cancer, and secondary neutrons—generated especially from the planetary surfaces—can be up to 20 times more harmful than other radiations.

Radiation shielding materials play a critical role in many commercial and industrial applications such as medical imaging and therapy, nuclear waste storage, space exploration, and food sterilization.

A new material has emerged that simultaneously blocks electromagnetic waves and radiation using a single ultrathin film. It ...

Developing high-density neutron shielding material using surfactant-stabilized boron nitride nanotubes (BNNT). (Nanowerk News) High-energy cosmic radiation damages cells and DNA, causing cancer, and ...
