You are all wrong in important places. For one thing the V in V/c^2 is
potential MG/r not acceleration MG/r^2. (Units, units) 
For another the clock was not moved. The radiation of 1 curie of the
stuff rose in a helium filled tunnel to the top. 
It is puerile to carry out whole number calculations to ridiculous
extremes when differentials would do it easier.
The energy is 14.4Kev with a hz frequency 3.482e18.
The rate of time never changes; that is relativity's false claim.
Clocks in a gravity well encounter a deprived environment and thus run
slower there.
Nobody compared any frequency. It's not possible. The detector was
moved on a voice coil and the Doppler effect recentered the frequency
to the resonance at the top filter.
