My friend who is a Radiologist said all the older, more seasoned Radiologists don't have any hair that grows on their hands anymore. She said she was glad to get out because even if they provide lead bibs, the doctors doing emergency radiology type treatments were still exposed long term.

That seems like it would be the most important part of the whole article, and it was left out.

It’s possible that the standards of evidence in a civil case is low enough that they don’t have to demonstrate a causal link. Only that there is radiation in the air and that radiation causes cancer.

This seems like pretty strong evidence that the Linear No-Threshold Model for radiation exposure is the correct model. Not great for the many companies attempting to revive the nuclear power industry.

The radiation exposure caused by the flight is a known. Fraunhofer institute once had the calculator they made for Lufthansa (if I remember correctly) publicly available. You could enter flight numbers and it would aggregate your exposure.

Speculation: Most forms of breast cancer occur because of bad protein production from a specific gene. My guess is this flight attendants breast cancer isn't from any known breast cancer gene.
