Erfarenheter och motåtgärder inom jordbruket i Jämtlands län efter Tjernobylnedfallet

This report deals with various aspects, on countermeasures taken to diminish the impact of the Chernobyl accident, in critical fallout areas of Jämtland county, in order to reduce the contamination of the farmers produce and food stuff items with Cs-137 in the years 1986 – 1992. At the time of the Chernobyl radioactive fallout in Sweden the growing season had not yet started in Jämtland county (middle east Sweden), where two moun-tainous agriculture areas were critically contaminated with Cs-137. There was thus time for consideration if these areas, sensible for transfer of Cs-137 to crops, could be used for further agricultural produce, or had to be excluded. According-ly, the Swedish government delegated to Swedish radiation safety authority (SSI) to set up acceptable limits for contents Cs-137 in food stuff items, and to inform regional authorities (Agricultural boards) to facilitate the accomplishment of investigations and field research, which effectively could decrease the transfer of Cs-137 to agricultural crop and animal products. In Jämtland county, agriculture animal and soil advisers were to take part in the direct information of the farmers. Agr Dr I. Bjäresten, animal adviser, is initiator and head author of the report. She was much engaged on all levels of developing and testing the countermeasures to be employed by the farmers, and especially so in the years 1986 and 1987. Agr B. Jönsson, soil adviser is author of the supple-ment, where he re-ports about soil conditions and experiences from the field con-tamination areas investigated in years 1986-1990. Docent K. Rosén, research scientist in radioecology and soil sciences, SLU, is a staff member of research teams on the Jämtland county. He was engaged to get the report published. The report comprises a description of steps taken between the national authori-ties and the Jämtland county administration board in the unexpected situation after the Chernobyl serious fallout. The administration board made many delega-tions to the regional farming advisers, of which the latter in turn cooperated with the farmers concerned, of the “mysterious” radioactive fallout on their fields, and with university departments working with radioecology in Sweden. Their task was to estimate effective decrease of the different countermeasures recommend-ed and to a great extent implemented by the farmers on field and animal levels. The report can be considered as a narrative or account of experiences obtained by Bjäresten during her work with suitable countermeasures to decrease conta-mination of plant and animal products from the contaminated area considered.
