Soils with high clay content tend to bind radioactive elements and hinder their travel, while sandy soils allow more of the radiation to pass into growing food.

粘土比例高的土壤更容易结合放射性元素，阻碍其进一步扩散，沙质土壤中的辐射物质更容易进入作物内。

Richer said that up to half of the stars in the universe were obscured by space dust and would soon be visible for the first time, thanks to ALMA's ability to pick up sub-millimeter radiation waves that pass through the dust unchecked.

When it is ground into nanoparticles it can still block harmful ultraviolet radiation, but it allows visible light to pass straight though, which means modern sunscreens can appear completely transparent, while offering the same protection as the old white stuff.

This is the point when neutrons released during the break-up of an atomic nucleus are more likely to hit and shatter other nuclei (thus releasing further neutrons), than to escape to the outside world where they merely generate Cherenkov radiation and tear up any living tissue that they pass through.
