Is there a conventional symbol for the set of radical expressions?

Question

There is already a question about the name of such a set: Name for numbers expressible as radicals

My question is related.

The rational complex numbers might be denoted ℚ(i), and the algebraic numbers are denoted . Between these two sets is that of radical expressions (the closure of the integers under arithmetic and radicals). Is there a conventional symbol for this set?

As an aside, are there any recommended references on the subject of radical expressions?

Maybe you’re talking about the maximal solvable extension of $\mathbb Q$? There’s no standard notation. — Lubin, Sep 26 '14 at 14:52
Thanks @JoseArnaldoDris. Now I need to find a Windows machine to look at that site… (It says Linux is an unsupported platform!) — Rhubbarb, Sep 26 '14 at 15:04

There is no conventional symbol for the set of radical expressions.

If you find yourself needing one, just define one and be explicit about it.
