What is the difference between antenna input impedance and its radiation resistance?

No. A standard 50 Ohm non-inductive resistor (e.g. dummy load) can have 50 Ohms of real impedance, but zero radiation resistance. Ideal full wave dipoles are a mathematical fiction. Real dipoles ...

What is the difference between antenna input impedance and its radiation resistance?

No, they're separate. Radiation resistance contributes to the real part of input impedance, but so does ohmic loss (heating), and non-radiative coupling with the EM field produces the imaginary part ...
