10 Key Points 

  • In 1956, the US National Academy of Sciences (NAS) released the BEAR I Genetics Panel Report on radiation risks.

  • Newly discovered letters reveal the public report was written by third-party authors from Scientific American without panel approval.

  • The published report misrepresented panel views and included scientific errors not endorsed by the genetics experts.

  • The report promoted the Linear No-Threshold (LNT) model, claiming all radiation exposure is harmful.

  • Panelists privately criticized the report, stating it contained inaccuracies and misleading language.

  • The NAS failed to disclose that the panel had not reviewed or approved the report before its release.

  • William Russell’s 1958 research showed radiation-induced mutations could be repaired, contradicting LNT assumptions, but this was ignored.

  • The misleading report heavily influenced US radiation policy, leading to strict safety standards and widespread public fear.

  • The authors argue the NAS committed a serious breach of scientific ethics by allowing inaccurate information to shape policy.

  • This paper recommends that the 1956 report be formally retracted to correct decades of misinformation in radiation risk assessment.
