Perhaps you should try some spelling variations:
decrease radiative » increase radiation (Expand search), decrease oxidative (Expand search)
radiative effects » radiation effects (Expand search), additive effects (Expand search), radiation effect (Expand search)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » brain decreases (Expand search), strains increases (Expand search), stress decreases (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease OR decrease strain decrease ) OR ( decrease NOT decrease radiative effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease OR decrease strain decrease ) OR ( decrease NOT decrease radiative effects ))*.
