We present direct measurements of the spatial distribution of
both ionizing radiation and low energy neutrons (E_n < 200 KeV) inside the
tracking volume of the Collider Detector at Fermilab (CDF).  Using data from
multiple exposures we are able to separate the contributions from beam
losses and proton-antiproton collisions.  Initial measurements of leakage
currents in the CDF silicon detectors show patterns consistent with
predictions based on our measurements.
