Abstract
<jats:p>The dose rate of gamma radiation in air at a height of 1 m above the surface of virgin (undisturbed) soil is the starting point in the basic model that is used to estimate the dose of external radiation to the population living in areas contaminated due to the Chernobyl accident. Today, i.e. more than 30 years after the fallout, the finding of truly virgin lands is a rather difficult task, because many meadows were repeatedly plowed and/or rehabilitated after the accident. The purpose of this study was to develop a quantitative criterion for the detection of virgin soil areas using a portable gamma-ray spectrometer-dosimeter. To achieve this, we have con...
