Radioactive contamination is revealed at the Sugano house in Ryozen, Date, using a special light painting technique. Surrounded by orchards and forest, the Sugano's property was decontaminated by officials, but it is continually re-contaminated by the surrounding land which was not comprehensively cleaned. Here we see radiation levels between 0.22uSv/h and 0.28uSv, with yellow showing spots elevated above the government decontamination target of 0.23 uSv/h.
