Beryllium in engines drama

[JohnP]

According to my Ilmor piston from 2000, the bore is 93.5 mm.

Do you have a source for x rays aren’t harmful?
Is the connection here that beryllium is also not harmful?

well pardon me for living !!

you can get the amjclinicaloncology article by searching (the link won't work)

feel free to show me where I have suggested or implied that beryllium can't be harmful
feel free to read the source material not just the Wiki story
feel free to look at the current regulations on Be working

I think you need to understand better what you read and the context in which it’s written.

And given your last question, you should also understand better the implications of what and how you write things.

Article only mentions the hazard model for low level radiation is probably wrong.
It specifically doesn’t mention “X-ray is harmless “

"X-rays use ionizing radiation, which can damage cell DNA and increase the risk of cancer over time. The risk depends on the amount of radiation exposure and the part of the body being X-rayed. Children are more sensitive to radiation than adults."

sorry but the above seems (to me) the vague but 'pile-on-the-condemnation' approach (that I had complained about)

significant (to me) is a statement elsewhere ....
(at c.20 min into the Thought Emporium youtube item titled 'taking X-rays using grandma's radioactive dishes') ....
'' as long as the exposure is brief enough and within certain known safe limits your body can fix any change without issue or increased cancer risk "


regarding beryllium ....
afaik no notable toxicity has developed from a single exposure event
if that is wrong - can someone show me (eg in source material used by Wikipedia) where it says so ?

From the National Library of Medicine at the NIH, a U.S. government agency: Beryllium Toxicity by Elaine R. Stearney; Julian A. Jakubowski; Angela C. Regina. https://www.ncbi.nlm.nih.gov/books/NBK585042/

Acute beryllium sensitivity and Berylliosis should be suspected in any patient presenting with respiratory complaints alongside known or suspected beryllium exposure. Acute beryllium toxicity will typically occur after exposure levels of 25 to 100 μg/m. It will typically manifest with inflammation of the upper and lower respiratory tract, similar to other cases of chemical pneumonitis.

I don't know if this answers your question about a single exposure, but it does mention exposure levels.
