Summary[edit]

Description
English: On April 26, 1986, an explosion in the nuclear power plant near Chernobyl, Ukraine, created a radioactive cloud that some days later reached central Europe. Radioactive fall-out particles sticked to the ground and plants. My colleague Tyno Abdul-Redah and me exposed grass leaves from our school yard in (at that time) West-Berlin to photographic plan film for 47 hours in a hermetically closed box. After its development the negative was copied on 10x15 cm photo paper which is submitted here as a scan. It shows the hot spots, namely caused by 131-Iodine isotope, as white spots on the grass leaves (the round dark spot origins from a coin, used to generate a contrast area). Our work was submitted to the German Competition for Young Scientists (jugend forscht) in 1987. Because of its background this image can also be regarded as a historical document.
