Mother of all cancer risk assessment regulation found to be science fraud

Climate junk scientist James Hansen wasn’t the first to use the term “loaded dice” in regard to alleged human enhancement of environmental risk. That “honor” goes to Science magazine which use the term in its editorial heralding its May 1957 publication of the foundational paper of all cancer risk assessment, E.B. Lewis’ “Leukemia and Ionizing Radiation.”

Here is the Science editorial.

Lewis paper was an immediate sensation, vaulting him from CalTech obscurity to headlines, NBC’s “Meet then Press” and congressional testimony.

Lewis’ paper changed everything in cancer risk assessment. It became the basis for the key regulatory assumption of the linear no-threshold model (LNT), i.e., there is no safe exposure to cancer-causing agents like radiation and chemicals.

But Lewis lied in his paper.

Lewis ignored warnings in three key data sets and inappropriately re-classified data in a fourth data set for the purpose of validating the politically motivated LNT, which at the time was being used as an argument to stop above-ground nuclear testing.

Lewis’ conduct is hard to explain by “honest error.”

Watch the University of Massachusetts-Amherst’s Ed Calabrese discuss all this in Episode 16 and Episode 17 of the Health Physics Society’s video series, “The Historical Foundations of the Linear No-Threshold Dose-Response Model for Cancer Risk Assessment.”

  1. The next hobgoblin or boogeyman is PFAS.

    Leftist “scientists” are freaking out over it.

    Even though these substances have been manufactured since the ’50’s.

    Of course, so predictably, EPA set the drinking water threshold at the method detection limit (4 ppt!).

    $$ billions more from EPA to States.

    Follow the money.

  2. of course the mavens and Brahmins of “science” will make you pry this from their “cold dead hands” because it is and has been a major source of power over us. They can and do make outrageous demands of us in the futile and stupid attempt at zero exposure to massive number of chemical and air pollutants. I give you PM2.5.

    The pols love it too, as there’s always one more agency to create or expand and one more hobgoblin to throw billions of tax dollars at.

    When are the adults coming home?
