Abstract: In this paper we examine eight popular books published immediately after the Fukushima Daiichi nuclear disaster. Our aim is to clarify the characteristics, problems in the scientific communication related to the health effects of radiation. The eight books are compared from the aspects of: 1) how units such as Bq, Gy and Sv are defined; 2) how the dose limits are explained; 3) how deterministic and stochastic effects of radiation are differentiated; 4) how LNT model is explained and evaluated; 5) how the fact that we evolved in the midst of natural background radiation is treated. The main finding of our survey is that although the authors of the examined texts start from the same 'scientific facts', in trying to make these facts easily understandable, they adopt different rhetorical strategies and eventually they end up delivering quite different and conflicting messages to the people.
