	The/at entrance/nn must/md have/hv at/in least/ap one/cd right-angle/nn turn/nn ./.

Some/dti will/md go/vb around/in a/at corner/nn ./.
The/at rest/nn continues/vbz in/in a/at straight/jj line/nn ./.
Therefore/rb ,/, sharp/jj turns/nns in/in a/at shelter/nn entrance/nn will/md reduce/vb radiation/nn intensity/nn inside/in the/at shelter/nn ./.
