Perhaps you should try some spelling variations:
radiation patterns » radiation pattern (Expand search), radiation scattering (Expand search), activation patterns (Expand search)
decrease radiation » increase radiation (Expand search), increases radiation (Expand search), decrease predation (Expand search)
decrease not » decrease akt (Expand search), decrease at (Expand search), decrease on (Expand search)
not decrease » not increase (Expand search), and decrease (Expand search), the decrease (Expand search)
decrease of » decrease in (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
of decree » of degree (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease NOT decrease of decree ) OR ( decrease to decrease radiation patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease of decree ) OR ( decrease to decrease radiation patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease of decree ) OR ( decrease to decrease radiation patterns ))*.
