If the underlying process is hot-fusion why wasn't Roger Stringham killed by the neutrons? Maybe it's a quite different process.
You ask a simplified question, without knowing the details.
ITER for example is man made hot-fusion, very uncommon in the rest of the univers and producing tons if neutrons. But T-D has a high Gamov-factor.
The main idea behind LENR is: Only very low energy levels (Some 10-100 eV) are needed to induce/produce the nuclear reaction.
In hot fusion You need higher energy levels (1000-30000eV) to start the reaction.
Hot fusion is kinetic (at least one reaction partner) - LENR is "static" as there is no real free path of movment for the reaction partners.
Now sonofusion: One reaction partner is kinetic. The cristaline needlike center of the colapsing bubble, which bangs into the lattice. (About mach 10) Thus sonofusion is similar to accelerator experiments shooting elements into to other target elements.
But to start a sono-fusion experiment You need only about 4 Watt input, the path of the bubbles is very short and after they entered the lattice the NAE is LENR.
But contary to most LENR reactions You get radiation. Most He4 is freed (==>Alpha radiation) and induces Bremsstrahlung (mostly "soft" X-rays).
Thus to my understanding classical LENR is fully contained in a close NAE which confines products and radiation.
It would be better we define a set of rules for nuclear reactions which allow to classify them exactly.
