The primary reason why many people with strong questioning attitudes have worked hard for several decades to prove that the geneticists on the first National Academy of Sciences committee on the Biological Effects of Atomic Radiation were wrong when they made the statement that there is no safe dose of radiation and threw out the preexisting threshold model of radiation health effects is that the model harms people.
IMO, It was that model that is primarily responsible for the unfair way that the Japanese have treated the hibakusha - the survivors of Hiroshima and Nagasaki. They were treated like people with infectious disease and have been viewed for decades as people who should be sequestered from the rest of society. That prejudice was strongly reinforced by the pronoucements of the Genetics Committee which declared that exposure to radiation at any level increases the rate of mutation and puts future generations at dire risk.
People are still kept from their ancestral land at Chernobyl and at Fukushima, being continuously harmed by the stress brought on by an irrational fear that has been carefully taught and reinforced.
People with medical conditions that can be diagnosed and treated with radiation shy away from allowing their doctors to use the most effective tools because they incorrectly think that the tool may contribute to a cancer development later in life.
The research would not result in an effort to redesign nuclear power plants to shave away a little material; but it should make the design, licensing, construction and operation substantially more economical by eliminating some of the fear induced resistance to nuclear energy. That ecessive fear is what drives people to file lawsuits, act out during public hearings, submit thousands of comments that must be addressed during the approval process, and makes siting a very useful, ultra-low emission power plant an onerous burden.
It is not a matter of "unbiased" science; it is a matter of basing rules on the best available, experimentally derived truth.
Explaining the need for the change gets easier as we gain more understanding about the very large financial reasons why our current model was so biased, so incorrect, and so carefully sold in the first place.
