title: Multi-fractal nature of radioactivity deposition on soil after the Chernobyl accident.
abstract: Fractal analysis is introduced in the field of environmental health physics. In particular, it is applied to the complex and inhomogeneous deposition pattern of radioactivity after the Chernobyl accident. The patchiness of 137Cs hot spots is quantified by a fractal dimension as low as 1. The problem of finding hot spots that might be of health concern is discussed.
