Proposal of new measure of radiation dose for a better understanding of radiation for the public

New nuclear power plants need to be built to provide clean energy which does not generate carbon dioxide. Building such plants requires agreement by the public on the necessity for the development of nuclear power programs. It is therefore important to provide the general public with an understanding of the true situation in matters of radiation and to assuage irrational anxieties. A new method of radiation representation is proposed which is based on the annual absorbed or exposure dose equivalent originating from natural radiation. The representation is considered useful to enable the general public to recognize the reality of the influence of exposure to natural radiation. A comparison is made between the risk of radiation and other toxic materials. The toxicity of chemical materials is measured by amounts occurring naturally in the human body in a method similar to that used in the case of nuclear radiation.
