There are various beam line components between the interaction point (IP) of the SLC and the beam dumps which will intercept enough beam to warrant calculating the radiation levels inside the final focus alcoves. The three types of devices which are of concern are the main dump, tune-up dumps, and adjustable collimators. Fluences of and doses from neutrons and photons in the alcoves are calculated. It is concluded that if the beam losses do occur as expected, many of the electronic components in the alcoves will begin to fail after a very short running period. The final focus is seen to be a hostile environment for sensitive electronics, and some combination of local shielding around the beam intercepting devices and shielding of the alcoves themselves is recommended if electronics are to remain in the tunnels. Annual doses in the alcoves are tabulated, followed by types, locations of devices and beam losses. (LEW)
