Yes.
The note in the docstring might be a bit cryptic but it is there (type
"I.radical?")
"""
Note: From the Singular manual: A combination of the algorithms of
Krick/Logar and Kemper is used. Works also in positive
characteristic (Kempers algorithm).
"""
Also see the source code (type "I.radical??")
import sage.libs.singular
radical = sage.libs.singular.ff.primdec__lib.radical
r = radical(self)
