Scattered radiation from trimmer bars in the cobalt-60 teletherapy machines. 1979

W J Graham, and D W Anderson, and C R Bogardus, and S E Acker

The amount of scattered radiation resulting from four Cobalt-60 teletherapy units in four different hospitals when trimmer bars were fully extended was studied. Scatter was present for all machines checked at between 10% and 20% of the central axis dose. Clinical significance is also discussed.
