'''Fear of radiation''' is one of the barriers to reconsidering nuclear power.  Government agencies have for decades assumed that deaths and other bad effects of radiation on our health follow a model called ''Linear No Threshold'' (LNT), in which death and disease is directly proportional to the total cumulative radiation, no matter how low the rate, even as low as the normal background radiation from space and the materials around us. This assumption ignores the data on low exposures (Figs.1&2) and the role of DNA repair in mitigating the damage done by low doses of radiation (Fig.3). Without a repair mechanism, the number of DNA breaks would simply accumulate in a linear fashion, no matter how low the exposure.

Over reliance on the LNT model has led to policies that are very costly, like radon remediation in old homes (Fig.4) and over-reaction to radiation accidents, like the evacuation after Fukushima (Fig.5), which caused far more deaths that the accident itself (Fig.6). It has also led to excessive fear of radiation from medical x-rays and other nuclear medicine procedures which save thousands of lives.

The LNT model has also been used to argue against expansion of nuclear power. It has lead to the belief that an accident causing a small increase in radiation over a very large area could lead to a large number of cancers and deaths. A more realistic assessment will show that the danger from nuclear power is much smaller than the public believes, and much smaller that the risks from ever-increasing CO2 in our atmosphere.

Fear of radiation is one of the barriers to reconsidering nuclear power. Government agencies have for decades assumed that deaths and other bad effects of radiation on our health follow a model called Linear No Threshold (LNT), in which death and disease is directly proportional to the total cumulative radiation, no matter how low the rate, even as low as the normal background radiation from space and the materials around us. This assumption ignores the data on low exposures (Figs.1&2) and the role of DNA repair in mitigating the damage done by low doses of radiation (Fig.3). Without a repair mechanism, the number of DNA breaks would simply accumulate in a linear fashion, no matter how low the exposure.

Fig.4 Eliminating small amounts of radon can be costly.

Reliance on the LNT model has led to policies that are very costly, like radon remediation in old homes (Fig.4) and over-reaction to radiation accidents, like the evacuation after Fukushima (Fig.5), which caused far more deaths than the accident itself (Fig.6). It has also led to excessive fear of radiation from medical x-rays and other nuclear medicine procedures which save thousands of lives.

It has lead to the belief that an accident causing a small increase in radiation over a very large area could lead to a large number of cancers and deaths.
