RADIATION STREAMING IN DUCTS AND SHELTER ENTRANCEWAYS. Final Report
Technical Report
·
OSTI ID:4795990
The attenuation of gamma rays in concrete walled ducts having two right- angle bends was measured. Both Z and U shapes were studied experimentally. The addition of a second right angle bend resulted in a large increase in the attenuation for gamma rays and the energy dependence of the attenuation was considerably reduced. For smaller ducts of cross section 1 by 1 foot, the attenuation of the second bend was far greater than for the larger cross section entranceway. (auth)
