I suspect that he simply does not understand the issues, and/or the
facts.  He, himself, basically makes the point that K-40 is in most
everything we eat, but then shoots himself in the foot in thinking
that Cs-137 (a K-analogue) is more dangerous, even though the t1/2 is
orders of magnitude shorter than that of K-40, and the gamma emissions
are much lower energy.

P.S.  In no sense does Cs-137 have a longer t1/2 than radium (Ra-226,
physical t1/2 ~= 1600 y).

scattered all over the place by above-ground
nuclear tests and the Chernobyl and Fukushima accidents has a much
longer half life, and can easily contaminate food and water supplies.
As the New York Times notes:
Over the long term, the big threat to human health is cesium-137,
which has a half-life of 30 years.
