In terms of RF exposure -- I don't think it's really all that different than, say, a Fisher 400.
In the 1950s and 60s, hifi components were typically sold
sans enclosure; the enclosures were
optional at extra cost.
The FM tuners in the Fishers, e.g., (including the entry level 400) worked... rather well actually.

That said, the Fishers were all point to point wired, so a little bit better perhaps than the current item under discussion.

That said, companies like harman/kardon made FM tuners and stereo receivers with crude PC boards in the 60s -- and they worked OK, too.
hk, for better or worse, were "early adopters" of PC board construction in hifi.

Of course, I'd be a little leery of the quality and extent of the
shielding in this current production "receiver".
... and... is it just me, or does this thing actually use
IF transformers -- or have they simply disguised ceramic filters or other components under imitation/artifical IF transformer cans? I haven't seen full-sized IF transformers since... well... the days of the Fisher 400!
As to kids and HV -- well... natural selection, you know?
