Just FYI, the standard way of connecting buried Cu radials to the Cu ring at
the base of AM broadcast towers is by brazing.
that's for an RF ground, and your periodic field strength measurements
would tell you if there's a problem with the connection. And, it's a
system that is regularly maintained and inspected. If it doesn't work,
nobody dies.
The safety ground has a different set of assumptions, essentially, no
maintenance, no inspection for life.
