In this paper, I argue on how the risk and anxiety of radioactive exposure after the Great East Japan Earthquake should be presented in TV programs. Many people in Japan still have much interest and anxiety about the effects of radioactive contamination, but a unified consensus about what kind of influence does radiation exposure have on us has not been reached among experts. Generally, TV programs are expected to be easily understandable; however, differences among experts on the evaluation and judgment of radioactive effects remain.
I analyze the TV programs on radioactive exposure related with not only the Fukushima 1 Nuclear Power Plant disaster but also the Hiroshima-Nagasaki atomic bombings and Chernobyl disaster because the purpose of this paper is to extract the commonalities of the radiation exposure discourses.
I analyze TV programs broadcasted since 1986 within the database of archives that can be easily accessed, such as the ‘NHK on-demand’ on the Web and the ‘Broadcast Library’ in the Broadcast Programming Center of Japan. I also use some TV programs which are broadcasted around March 11, 2014. They were collected by myself.
I pay attention to the construction of scientific reality based on “laypeople's discourse” and “numeric data.”
By analyzing the discourses on radiation exposure through several decades, we find that experts have failed to explain influence of the radioactivity radiation exposure clearly . Many experts explain that the status of anxiety and interest in the “present” transferred to the “future” as being vague.
I analyze not only discourses of experts but also those of laypeople; as a result, we realize the importance of the role of laypeople in understanding the explanations of experts on TV. When experts talk about radiation with scientific uncertainty, laypeople's discourses support them so that they are easily comprehensible for the audience of the TV programs.
