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 doe s not generate carbon dioxide. Building such plants requires agreement by t he public on the necessity for the development of nuclear power programs. I t is therefore important to provide the general public with an understandin g of the true situation in matters of radiation and to assuage irrational a nxieties. A new method of radiation representation is proposed which is bas ed on the annual absorbed or exposure dose equivalent originating from natu ral radiation. The representation is considered useful to enable the genera l public to recognize the reality of the influence of exposure to natural r adiation. A comparison is made between the risk of radiation and other toxi c materials. The toxicity of chemical materials is measured by amounts occu rring naturally in the human body in a method similar to that used in the c ase of nuclear radiation.
