Nuclear radiation shields, shielding systems and associated methods

A shield for attenuating nuclear radiation or ionizing particles, comprising:

• a plurality of layers that are at least partially superimposed relative to one another and that are enabled to move longitudinally relative to one another;
• and
• a radioactivity-attenuating material in at least one layer of the plurality of layers.

A shield for attenuating nuclear radiation or ionizing particles, comprising:

• a first radioactivity-attenuating material for attenuating nuclear radiation or ionizing particles having a first range of energies;
• and
• a second radioactivity-attenuating material for attenuating nuclear radiation or ionizing particles having a second range of energies, the second range of energies differing at least partially from the first range of energies.

A material for attenuating nuclear radiation or ionizing particles, comprising:

• a pliable component configured to be molded into a shape and retain the shape;
• and
• at least one radioactivity-attenuating material dispersed throughout the pliable component.

A material for attenuating nuclear radiation or ionizing particles, comprising:

• a flowable component configured to be applied to coat a substrate;
• and
• at least one radioactivity-attenuating material dispersed throughout the flowable component.

A method for limiting a dosage of nuclear radiation or ionizing particles to which an individual is exposed, comprising:

• positioning a low Z radioactivity-attenuating material between a source of radioactivity and the individual to absorb incident nuclear radiation or ionizing particles from the source;
• and
• positioning a high Z radioactivity-attenuating material between the low Z radioactivity-attenuating material and the individual to absorb secondary ionizing radiation from the low Z radioactivity-attenuating material.
