Materials/Shielding
Shielding
shieldingWhat this is
Materials that block radiation, such as hydrogen-rich polymers, water and boron compounds.
Radiation harms people and electronics. The question is how much dose a material removes for each kilogram it adds.

What matters
The measurements we use to compare shielding. Each one has a standard test and a direction: is higher or lower better?
| Measurement | Better when | How it is tested |
|---|---|---|
| Radiation shielding per massDose reduction per kilogram of shield | higher | Shielding studies at equal areal density |
