为了证实放射性铯污染在莱茵兰-帕拉特纳部分地区野猪中的途径，我们分析了2001年1月至2003年2月期间在帕拉特纳森林西部45,400公顷范围内射杀的2,433头野猪的放射性铯浓度。此外，对于2002年5月至2003年2月期间拍摄的689只动物的一小部分，我们收集了它们的胃，以检查它们的含量和Cs-活度浓度。野猪肉类污染遵循季节曲线，夏季最大比例超过可接受水平(21-26%)，冬季最低水平(1-9.3%)，表明植被期间污染源的消耗量较高。秋季的下降显然归因于低污染山毛榉坚果的广泛消费。准确分析了18个Cs活度浓度最高的胃[345-1,749 Bq/kg(新鲜物质：FM)]和18个Cs活度浓度低的胃(
To substantiate the pathways of radiocaesium contamination in wild boars in parts of Rhineland-Palatinate, we analysed radiocaesium-activityconcentration of 2,433 wild boars shot in an area covering 45,400 ha in the western part of the Palatinate Forest between January 2001 and February 2003. Also, for a fraction of 689 animals shot between May 2002 and February 2003, we collected their stomachs for the examination of content and Cs-activity concentration. Wild boar meat contamination followed a seasonal curve with maximum proportions exceeding accepted levels in the summer (21-26%) and minimum levels in winter (1-9.3%) indicating a higher consumption of a contaminating source during the vegetation period. The autumn decline is obviously attributed to the extensive consumption of low-contaminated beech nuts. An exact analysis of food composition in 18 stomachs with maximum Cs-activity concentrations [345-1,749 Bq/kg (fresh matter: fm)] and 18 with low Cs-activity concentrations (
