Zhytomyr Oblast in Ukraine was contaminated by radiation from the Chernobyl nuclear disaster, and residents continue to suffer from radiation poisoning caused by ingesting contaminated crops. The Association to Help Chernobyl, Chubu-District, Japan has recognized the ability of rapeseed to absorb radioactive substances (including Cs137 and Sr90), and since 2007 it has been implementing a project that cultivates rapeseed in contaminated areas, uses the rapeseed oil produced to create biodiesel, and then uses the waste left after harvesting as biomass fuel and waste from oil production to manufacture biogas. This project will encompass the fourth and fifth years of a five-year plan, and will include initiatives to prevent damage from continous rapeseed cultivation, and the development of effective cultivation methods. This will contribute to improving soil conditions in contaminated areas, reducing radiation poisoning in local residents, and revitalizing regional agriculture through biofuel and energy production.
