Apparatuses and methods employing multiple layers for attenuating ionizing radiation

摘要

Radiation shields and radiation shielding systems for attenuating ionizing radiation include two or more attenuating elements, such as layers. The two or more attenuating elements may include different attenuating materials. The two or more attenuating elements may be configured to attenuate ionizing radiation differently than one another. In some embodiments, different attenuating elements may be configured for use with different energies or ranges of energies of ionizing radiation. The concurrent use of two or more layers or other attenuating elements may optimize the ability of a radiation shield to attenuating ionizing radiation. Systems and methods for attenuating ionizing radiation are also disclosed.

主权项

1. A radiation shield comprising a radiation attenuating layer, comprising:
a first sublayer comprising a first radiation attenuating material comprising a salt of a first elemental species having a first atomic number; and a second sublayer comprising a second radiation attenuating material comprising a salt of a second elemental species having a second atomic number, the second atomic number being higher than the first atomic number; wherein the radiation attenuating material of the first sublayer differs from the radiation attenuating material of the second sublayer, and wherein all the radiation attenuating materials in the radiation attenuating layer are salts of an elemental species.
