Atomic Show #239 – Sarah Laskow and the LNT model

In March 2015, Foreign Policy magazine published an article by Sarah Laskow titled The Mushroom Cloud and The X-Ray Machine. The article described the controversy over the radiation protection model known as the linear, no-threshold dose response.

Ms. Laskow conducted some admirable literature research and talked with a number of well-known people.

The ones that made it into her article as quoted sources included Dr. Tony Brooks, Chief Scientist of the Department of Energy’s Low Dose Radiation Research program, Dr. Helen Caldicott, a long time antinuclear activist, John Boice of the National Council on Radiation Protection, Dr. Ed Lyman of the Union of Concerned Scientists, Dr. Greg Jaczko, who was Chairman of the Nuclear Regulatory Commission until asked to resign because due to a loss of confidence in his managerial performance, and Dr. David Brenner from Columbia University and Image Gently.

From my point of view, her choices for quotable sources were not especially balanced; Tony Brooks is the only person in the above list whose scientific research has led him to the conclusion that the LNT overestimates radiation health risks at low doses. John Boice isn’t sure and wants another 7 years and $25 million to conduct additional epidemiological research while the rest firmly believe that there is no safe dose of radiation.

Sarah agreed to fit me into her busy schedule to about her article.

We talked about our respective research into the history of the LNT model, the biological logic guiding those who question the no safe dose assumption, the choices made during the process of editing her piece to fit the space available, and the difference between interviewing a variety of people with opposing points of view and seeking scientific truth.

We also delved a bit into the financial and political motives that underly certain policies that are supposedly based on sound scientific research and truth.

I hope you enjoy the conversation and learn something about how opinions are formed and shared.

Consumer Reports Editor Clings to LNT to Spread Uncertainty About Radiology

Consumer Reports, a widely read magazine in the U. S., has published more than half a dozen articles in the past couple of years warning people that every CT scan carries with it the risk of causing cancer. Here are the headlines of those articles. Consumer Reports: January 03, 2013. Many patients unaware of radiation […]

Time to stop consuming precious resources to harmonize occupational dose limits

Pressure groups and interested individuals have been striving for more than two decades to force the U. S. to reduce its occupational worker radiation protection limit from 50 mSv/year to 20 mSv/year. The primary justification for this effort is that in 1991 the International Commission on Radiation Protection (ICRP) issued publication 60 and provided their […]

Tritium – aka radioactive hydrogen – from reactors is not a threat to human health

Fukushima Tank Farm

Tritium, also known as radioactive hydrogen, is an isotope that releases an 18 Kev beta particle. The isotopic half life is about 12 years. Among other possible production mechanisms, it is produced in low quantities and concentrations in any reactor where water is exposed to a neutron flux. The production rate is higher in heavy […]

Science has falsified the “no safe dose” hypothesis about radiation. Now what?

There is a growing understanding among people who specialize in understanding how ionizing radiation affects human beings that the prevailing “no safe dose” model that was adopted as the result of a major political struggle during the mid to late 1950s is false and does not represent reality. Responsible people that continue to accept and […]

Health effects of nuclear radiation in plain language

CuttlerRadiationJan2013

By Jerry Cuttler, DSc, PEng All organisms have very remarkable protection capabilities. While most people still think that living cells are structurally stable, scientists discovered in the 1980s that cells undergo a very high rate of naturally-occurring physical and chemical damage caused by the heat, oxygen and other chemicals in their bodies. Approximately 10,000 measurable […]
