Not its not.
Very high energy photons or not easy to shield, and shielding will often
make matters worse because you'll get a cascade of particles creating by the
photons interaction with the shield...
If easy to shield includes, putting the equipment 6000 feet underground, you
are perhaps correct though.
By comparison, neutrons are probably easier to shield. A strong neutron
absorbing isotope, several feet thick (maybe), may not be very portable, but
it sure beats a mine shaft.
