This is only true to any degree if you are talking about buried, BARE
radials. If also uniformly spaced, elevated or insulated radials make
use of uniformity to achieve a degree of loss-avoiding field
cancellation underneath the antenna. Current in elevated or insulated
radials shorter than an electrical quarter wavelength will tend toward
a longer radial, due to its lower individual impedance. In a
non-uniform collection of radials, the least reactive lengths at the
operating frequency will carry more current.
