Autoradiograph - visualize radiation since 2011 


In 2011, huge amounts of radioactive particles were released into the air from a nuclear power plant in Japan. More than 70,000 people had to be evacuated from neighbouring towns and communities. Thereafter, concerns about food safety and health spread across the nation. And even now, the problem of how to dispose of the contaminated soil collected in the decontamination work is a major issue.

The radioactive contamination continues to be hotly debated throughout Japan and is a recurring topic in the media. And yet, very few have taken on the task of capturing a visual image of the harmful radiation for the public to see, such as enabling people to see the radiation emitted by objects directly subject to the fallout.

Masamichi Kagaya decided to leave behind as many visual records of the contamination from the nuclear disaster in 2011 as possible. Working in cooperation with Satoshi Mori, Professor emeritus of the University of Tokyo, Kagaya has used a technique called autoradiography to make radioactive contamination visible, covering a wide array of specimens from daily necessities to flora and fauna in the past 5 years.
