Dentist radiation chart Answered

Living in a rock or brick house exposes you to 700 times the radiation as eating a single yellow banana !
A BBC chart shows a banana as 0.1 radiation units and rock/brick homes as 70 radiation units and
flying a trans continental aircraft is much worse in exposing you to radiation...

You know, eating a single banana per day, for a year, exposes you to 365 times the radiation of eating a single banana.

Regrettably we all need more then trace amounts of Potassium for our nervous system to function... A simple blood test can be used to determine the content of potassium in your body... But does not break down the three isotopes of potassium, of which 40K is radioactive. Traces of 40K are found in all potassium, and it is the most common radioisotope in the human body

Also banana groves down wind of Chernobyl may upset this ratio !

Occasionally I see, or hear, these stories about how human health could be improved, if only there were an inexpensive way to make potassium, with just the stable isotopes, of mass 39 and 41. I guess it could be called, "depleted potassium", meaning depleted of the mass 40 isotope.

The other day, when I was trying to answer the latest water-electrolysis question in the Answers forum, I was looking at some of Cody Reeder's Youtube videos(i.e. Cody's Lab Youtube channel), and one of the videos I noticed was him making some noises about, "depleted potassium", here,

Cool set of vids.. Never realized how gamma 40K decay could be that high.

Of course they don't really explain how to deplete potassium..

Maybe we could find a use for all those New confiscated centrifuges the USgov has stock piled in the warehouse right next to the "Arch_of_the_Covenant" box..

Yeah. Leap years. I guess they're a little longer than regular years.

Or 365 and a 1/4. Depends how you look at it :)

(note: I might have a mistake in my calculations due to tjhe fact that I don't like bananas)

Do not forget that our kidneys eliminate excess potassium through urine; some is eliminated in sweating. This places an upper bound on banananical radiation !

I presume you meant to provide a link to the "BBC chart" you mention. I much prefer the XKCD one: Radiation

I much prefer your excellent Sievert radiation chart to the small BBC wall plaque that I perused two weeks ago at the dentist while waiting for a CNC machine to produce my new ceramic molar cap... It is gratifying to note that the banana=> o.1uSv / stone_house=> 70uSv was properly remembered leading to my 700x conclusion..
