At the level you could be casting this teleport can lift a typical
party of PCs.

The problem here is that you're not creating a big enough chunk. If
it's just a critical mass it goes poof. Lethal radiation, nothing
more. (There was a real-world case, the guy was only some feet from
the poof. He was knocked off a catwalk but lived long enough to run
out of the building.)

You only need an implosion because you need a means of converting the
subcritical chunk of plutonium *QUICKLY* into a highly supercritical
chunk. If you don't do it fast enough the heat produced blows it
apart too early. (Actually, in all cases the heat blows it apart
before you're done. The objective is to get as much of the energy out
as possible before that happens.)
Since we are using polymorph we don't need all that fanciness, though.
A critical mass of plutonium (assuming no reflectors, implosion or the
like) is a ball 4" across. Lets make a ball 12" across with the
polymorph. The center part of that ball is way into the supercritical
realm. Hello mushroom cloud.
It's nowhere near as efficient a use of plutonium as a properly
designed bomb but since we are just doing a polymorph efficiency
doesn't matter.
Anyway, I realize I did it wrong. We shouldn't be polymorphing
lead--that's too much like plutonium. Instead, we want something far
from plutonium so the duration is short.
Thus I present the plutonium turkey. The duration will be only 1
round/level. Lets say we are level 20, it lasts two minutes.
Our turkey goes boom and two minutes later virtually all the fallout
vanishes! (On the other hand you might say the fallout vanishes
instantly anyway as it's now separated from the polymorphed item.)
