This paper deals with the 137Cs airborne radioactive concentration measured in Northern Italy after the Chernobyl accident. We devised a fractal model to aid in describing the space-time distribution of radioactivity. The model is based on the Fractal Sum of Pulses theory, involving additive stochastic processes. We use, as input source of information, the parametrization of the time trend of radioactive concentration in a few Italian Provinces we calculated in previous work. The results look promising, since realistic scenarios of environmental pollution are produced.
本文探讨了切尔诺贝利事故后在意大利北部测量的空气中铯 - 137放射性浓度。我们设计了一个分形模型来帮助描述放射性的时空分布。该模型基于脉冲分形和理论，涉及加性随机过程。我们使用在先前工作中计算出的意大利几个省份放射性浓度时间趋势的参数化作为信息输入源。结果看起来很有前景，因为生成了环境污染的现实情景。
